Hi, My name is Loren Greenman, and I am running Cygwin at home. When I log in remotely (secure shell) to the computers at where I work, I am unable to run application that require OpenGL. I have downloaded the OpenGL library, and am otherwise up to date on Cygwin. However, I still get an error that says OpenGL not available whenever I try to use this program. My graphics card has OpenGL capabilities, and when I run a OpenGL test program from Cygwin it works, but when I try it after remotely logging into another computer I am unable to use this program. Any help is greatly appreciated. Loren Greenman

Loren, Considering the message that made it to the list just before yours (http://cygwin.com/ml/cygwin-xfree/2004-07/msg00074.html), the choice of ALL-CAPS for the subject was perhaps not the wisest... :-) More below.

Any help is greatly appreciated. Loren Greenman I believe you're confusing the native OpenGL support (which you get from the opengl package) and the OpenGL/GLX extension for the X server. The OpenGL test program is most likely running using the native OpenGL. For the remote program to use OpenGL, you'll need to have the GLX extension enabled in the X server. While from what I recall it is already working (see http://cygwin.com/ml/cygwin-xfree/2004-03/msg00323.html), you'll need to post the exact error message you're getting and the exact commands you used to invoke your XWin session and the failing program. You might also be asked later to post /tmp/XWin.log from a failed session. Igor P.S.

How to use ddd with XWindows?

H... I think that is the command I use on Linux. I tried it on Win2003 server running cygwin and there is no such command. I'm using the command XWin.exe and I'm trying to run the ddd debugger. XWindows seems to start OK. I can run X utilities like the XClock. However, when I try to start ddd main_assert.exe I get the Error: Can't open display:. Someone in the [EMAIL PROTECTED] mailing list suggested I need to set the display and then I was chastised for carrying on off topic. Can someone help me run ddd?

That is not correct at all, and rsync would be much less useful if it were true. rsync works with arbitrary binary data just as well as it does with text. It has no conception of 'lines' or any other type of delimited text. All it does is split up the file into fixed-length chunks and calculates a rolling checksum of each of these. It does not use anything resembling 'diff' or 'patch'. http://rsync.samba.org/tech_report/node2.html Thanks for clarification. Makes sense. So as punishment I made another bench. What is the maximum overhead? It cannot be the reported difference (factor 500). http://rsync.samba.org/tech_report/node6.html has about a similar filesize (2.1MB binary). In this example with a hit:miss ration of 64247:948 the overhead is 5312200:5629158+1632284 (if read and write is synchronous) compared to rcp. So about max 2.5 overhead, and not 500.

Re: rsync very slow, but not a network issue
* Alexis Gallagher (2004-07-12 19:46 +0200)
I am finding that rsync+ssh is giving extremely slow file transfers. But
this slowdown is hitting not when it needs to send data over the
network, but when it applies the rsync algorithm which is supposed to be
faster than sending all the data over the network. This is very puzzling.
For a benchmark, I tried transfering a 5.4 MB mp3 file three different
ways. Here were my results, as reported by 'scp -v' and 'rsync
--progress --stats':
scp: 311000 B/s
rsync (file not there): 309000 B/s
rsync (file already there): 741 B/s
When the file is alredy there, rsync reports a speedup of about 70.
(When the file is not already there, the speed up is 1, of course.) I am
running rsync over ssh with pre-generated keys installed in my .ssh
directories.
rsync under Cygwin is extremly slow and CPU intensive. For example a
simple script that syncs my dot files from my local NetWare server
takes 1:10 minutes to run and eats about 60% CPU while on my Gentoo
box (which has exactly the same hardware) it takes 7 seconds and 2%
CPU.
Try disabling checksumming, zipping and transfer the whole file
('-W'). Try it without ssh.

Re: rsync very slow, but not a network issue
Ok, Now this is progress. When I use '--size-only' then I do see a speedup. The 'transfer' is virtually instantaneous on the stopwatch, and 'rsync --stats' reports a speed of a mere 25 bytes/sec but with a reported speedup of 78125. I can see why this works, but I remain confused why I should need to resort to it. This is basically dispensing with the rsync algorithm, no? The cygwin machine is a Pentium III, 966 Mhz, 512MB of RAM. And the OSX machine is a 1 Ghz PowerPC G4 with 256MB of RAM. I can't believe everyone would use rsync as much as they do if it were not useful on machines of such specifications. Is there a way to benchmark its hashing algorithm on both sides? Maybe the rsync process is getting insufficient priority on one side of the transfer?

Re: FAQ update suggestion for I'm having basic problems with find. Why?
On 2004-07-08, Larry Hall wrote: At 10:02 AM 7/8/2004, you wrote: I have been using *ixy-type systems on and off for what must now be 16 years, including using find. I was using find today on an UDF/ISO format DVD-R, and was perplexed by it seemingly missing out large chunks of the hierarchy at random. It seems that find has an optimisation relating to the hard link count on directories and the presence or otherwise of the . and .. objects. If the filesystem you are finding on doesn't have the . and .. objects then find will fail silently(!) To get it to work, you need to turn the optimisation off with the - noleaf option. This is documented in the man page, but when you come to the symptoms cold, it looks more like a subsystem issue than an application issue, so it didn't occur to me to look in the documentation for find. The problem here is that the route to discovery of the solution is somewhat tricky. (In fact you could say that it is a dangerous optimisation in find. If the optimisation is not valid, there are no error messages and it fails silently. I guess I should be looking to see if this issue has already come up on the upstream version of find.) Right. I'd agree with this notion. My point is this: Whilst this is not an issue with Cygwin per se, the nature of Cygwin means that this issue will tend to arise commonly with Cygwin, and tend not to arise under traditional unixes. Why's that? Traditional unixes have been around for longer. Cygwin contains more to do with joining together stuff which has origins in different paradigms, so you are likely to see more problems with edge cases. Perhaps it would be a good idea to mention this issue in the Cygwin FAQ? Possibly as a second point under the existing heading of I'm having basic problems with find. Why? We could have an extra paragraph that goes something like this: If find does not seem to be producing enough results, or seems to be missing out some directories, you may be experiencing a problem with one of find's optimisations. See the documentation for the option '-noleaf' in the man page. That seems to be reasonable wording. But my inclination would be to get the results of more research into the 'find' issue before adding this to the Cygwin doc somewhere (not sure if the FAQ is quite the right spot given that we haven't seen allot of questions about it - at least not yet ;-) ). Would you be able to look into this further? On Windows XP over NTFS, find apparently worked fine without the -noleaf option. On Windows XP over three DVD-R discs, each containing a distinct data set, all laid out in UDF/ISO format using Ahead Nero 5.5, find required the -noleaf option in order to find all the objects as expected. The three discs were an archive copy of a hard disk from a notebook PC, with the files spread over three DVDs with the decision as to which disk each group of files was placed on made by estimation of usefulness. Discs 1 and 2 contained only one directory at the top level of the hierarchy called Documents and Settings. All other objects were below that directory. Disc 3 contained multiple directories and files at the top level of the hierarchy. The command lines containing find would be: cd /cygdrive/e find -type f -print0 | xargs -0 md5sum | sort +1 somefile find -noleaf -type f -print0 | xargs -0 md5sum | sort +1 somefile (Where /cygdrive/e refers to a DVD reading drive.) The idea is to get a file containing a list of MD5 sums of all files in the hierarchy. The number of search hits returned was as follows: Disc 1 without -noleaf: 0 hits with-noleaf: 7379 hits Disc 2 without -noleaf: 0 hits with-noleaf: 4325 hits Disc 3 without -noleaf: 17618 hits with-noleaf: 37973 hits I also made a list of MD5 sums from the original notebook hard disk using a similar command line. Combining the MD5 sums lists from the DVD-R discs, then sorting the results and comparing with the MD5 sum list from the original hard disk results were as follows: DVD-R discs read without -noleaf: Huge numbers of files completely missing from DVD-R set DVD-R discs read with -noleaf: Minor differences which could all be explained by: (a) Filename truncation on DVD-R filesystem (b) Permissions issues on the hard disk NTFS filesystem (c) Fondling of files by Windows XP in meantime (e.g. desktop.ini) So, from this my conclusion was that -noleaf was necessary when reading from a DVD-R filesystem made as described above. The result of zero hits when the top level directory only contains one directory is consistent with the behaviour described in the find documentation under the -noleaf option. I had Googled for a while to try and find the answer, but to no avail. My search did lead me to the Cygwin mailing list, which lead me first to a suggestion that I read the Cygwin FAQ. The Cygwin

dlopen under cygwin
Hi all, Is dlopen() friends supported under cygwin? If so, is the DLL that gets loaded using dlopen() a regular Win32 DLL, or a 'special' type of cygwin DLL? Reason I ask it that (while trying to get 'plugins' to work under cygwin) I had a look at the gmodule source code of glib, and it seems that gmodule uses regular Win32 LoadLibrary() calls to load the DLL, instead of calling dlopen(). I was wondering if that it actually correct.

Reini's issue was that cat
/proc/registry/HKEY_PERFOMANCE_DATA (yes, I didn't notice the typo

You also made a typo of your own there: he wasn't reading the key
/proc/registry/HKEY_PERFOMANCE_DATA but the default *value* for that key,
indicated by /proc/registry/HKEY_PERFOMANCE_DATA/@
Yep, I noticed this after I sent the message, but that didn't change the
point of the comment, so I didn't bother to correct it. FWIW, another
interesting fact is that on my system, ls HKEY_PERFOMANCE_DATA from
/proc/registry prints @ @ (i.e., *two* default values), neither of
which can be stat()ed.

believe to be perfectly valid behavior. He wasn't getting

I know. I didn't say he was (getting segfaults). I just pointed out
a couple of interesting things I discovered while trying to reproduce
his bug. I also explained why your interpretation of MSDN was incorrect.
Right, I interpreted the key as a stream (which is actually what cat
does), and you're right that at the low level keys aren't streams, so that
paradigm shift happens somewhere in the /proc/registry fhandler.
However...
A registry key simply isn't something you can go on and on reading from.
This is where you're wrong. Here's an excerpt from the MSDN documentation
on RegQueryValueEx
(http://msdn.microsoft.com/library/en-us/sysinfo/base/regqueryvalueex.asp):
If hKey specifies HKEY_PERFORMANCE_DATA and the lpData buffer is
not large enough to contain all of the returned data,
RegQueryValueEx returns ERROR_MORE_DATA and the value returned
through the lpcbData parameter is undefined. This is because the
size of the performance data can change from one call to the next.
In this case, you must increase the buffer size and call
RegQueryValueEx again passing the updated buffer size in the
lpcbData parameter. Repeat this until the function succeeds.
You need to maintain a separate variable to keep track of the
buffer size, because the value returned by lpcbData is
unpredictable.
So, in effect, you *do* need to treat HKEY_PERFORMANCE_DATA specially, and
the /proc/registry fhandler in fact does. Also, I think I may have found
the source of the bug. See below.
There isn't a single key anywhere in the registry that has any kind of
EOF whatsoever, so the lack of one on this particular key can't make the
difference.
True, I apologize for the wrong terminology.
I didn't get around to trying the actual cat instruction he quoted.
I'll try it now:
[EMAIL PROTECTED] ~ cat /proc/registry/HKEY_PERFOMANCE_DATA
Segmentation fault (core dumped)
[EMAIL PROTECTED] ~ cat /proc/registry/HKEY_PERFOMANCE_DATA/@
And then it hangs, as described. Takes (up to) 100%cpu, as well. However
I find that unlike Reini, I can kill it easily enough:
[Window 1]
[EMAIL PROTECTED] ~ cat /proc/registry/HKEY_PERFOMANCE_DATA/@
[Hangs. Meanwhile in window 2:]
[EMAIL PROTECTED] ~ ps

gcc: How does gcc look for foo.dll in `gcc ... -lfoo'?
I'm confused since the gcc documentation says that the only thing that `-lfoo' does, is that it allows gcc to look for `libfoo.a' while linking. But what about the shared libraries (DLLs)? It seems to me that gcc looks for `libfoo.dll', `cygfoo.dll', `foo.dll' and may be for all these plus `.a' suffix, doesn't it? But, for example, libfoo and cygfoo could be two _different_ libraries at all. Can anybody explain the -l feature for DLLs?

I've tried the Cygwin's User Guide and gcc info, but did not find any answer. Given you have a library 'mfoo', then you should have a file libmfoo.a in /usr/lib which is the static archive in the default search path. you specify this archive at the gcc link command with -lmfoo, if this library is a shared library, you should have also an import library /usr/lib/libmfoo.dll.a and a DLL /usr/bin/cygmfoo-2.dll, the default search order is /usr/lib, /usr/bin and then libmfoo.dll.a, libmfoo.a, cygmfoo.dll. So if you have just a static archive, it is found, if you have an import library and a static archive at first the import library is used (if not -static is used at the link command). If the import library is used, ld knows how to find the correct DLL and links the application against the DLL using the import library. If there is no static archive and no import library, then also /usr/bin is searched and also the cygmfoo.dll would be found, but if its actual name is cygmfoo/2.dll you would need to specify -lmfoo-2 at the link line to succeed the direct linking with the DLL. Additionally you may specify the full name with path to link against: gcc -o myapp.exe main_object.o /usr/lib/libmfoo.dll.a or gcc -o myapp.exe main_object.o /usr/lib/libmfoo.a or gcc -o myapp.exe main_object.o /usr/bin/cygmfoo-2.dll Gerrit -- =^..^= http://nyckelpiga.de/donate.html -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

Re: need -mrtd to create Excel DLL?
Siegfried:
Hi. I did not use any __declspec keywords, etc. -- just vanilla C
code which runs as well under gcc or g++ under Cygwin, FreeBSD, or
SPARC/Solaris, etc. Creating DLLs is another matter -- I've just tested
this using Cygwin/gcc under XP Pro. As I said, I cannot get this to
work under Cygwin/g++.
I tested the application with Excel using the dlltest.xls file in
http://www.xraylith.wisc.edu/~khan/software/gnu-win32/
but without the other modifications in his cdll.[ch] files.
To use his dlltest.xls, I named my DLL the same, and created
double dll_double_square (double d)
as one of my functions which called a series of other functions in other
files before returning.
I used the following lines in my Makefile. No other special code changes
were required in any of my .c or .h files:
CC = gcc
MY_OBJS = \

DLL_OPTION=-mrtd # needed for Excel DLL
CYGWIN_OPTION=-mno-cygwin $(DLL_OPTION)

How to update official cygwin documentation for g77 and gcc? (was: RE: need -mrtd to create Excel DLL?)
Lester,
Yeah, I did the same (with regard to __declspec keywords). Odd, Excell
won't read the DLL but C# will! I was just using Excell because it was handy
to test with. Good thing I really don't need excel. My real concern is
calling g77 from C# (which works). I got C# to call gcc too under cygwin.
Too bad my email wrapped my carefully prepared sample source code.
So our examples should go into the cygwin documentation! How can these be
inserted into to the documentation? Can someone tell us? Surely there will
be others who don't want to buy the Microsoft C++ or FORTRAN compilers but
want their C/FORTRAN code to interact with other Microsoft languages like
C#, VB.NET, Javascript.NET, J#.
Incidentally, I did discover that Microsoft is giving away their C/C++
compiler these days. It is part of the .NET Framework SDK (go to
http://search.microsoft.com to look for it). This free version of the
compiler seems to be able to compile C++ but does not have the standard C++
header files, only the standard C header files. I assume folks would still
prefer g77/gcc to Microsoft's, however. Oopss -- that is off topic. Sorry...

FYI: cygwin1.dll build 0701 fixed a file-permission-over-SMB problem I had
Just a thanks, y'all! We have what I believe is an oldish Snap! server here that we export some network shares from. My 1.5.10-3 dll was failing (specifically, vim 6.3 and perl 5.8 couldn't write files on it, although bash had no problem [echo foo foo.txt]). The 0701 build seems to have solved my problem.

I have a theory that the performance data may be added in chunks larger
than 1000 bytes, so the fhandler just can't keep up with the amount of
data, and loops indefinitely. Since you intend to build the DLL from CVS,
you're probably in the best position to check whether this theory is true
(by either just upping the increment amount to something like 5000, or
even doubling the buffer size on each iteration).
Perhaps bufalloc += max(bufalloc, 1000);

Sorry, but no. This will do nothing for the original problem. The idea
was that at some point you need the rate of buffer size increase to
overtake the rate of performance data generation. If performance data is
generated faster than 1000 bytes per query, and adding 1000 bytes isn't
enough, adding *at most* 1000 bytes (as you suggested) is strictly less
effective. I suggested a linear function with a steeper slope (which may
not be enough) or an exponential, which will definitely be enough, but may
introduce huge buffers.
I'm going to build the DLL from CVS now to test the theory. If it is
confirmed, then we can talk about a good buffer size increment function
(probably on cygwin-developers, though).

Firewall issue

I'm using the PC as a holding area for backups so that I don't have to write the backups to CD every day. The network card in the PC is a Kingston Etherex card, and it's not very widely supported on a Linux that fits on 1.2 gig with so little RAM. Anyway, I've hooked it up to my network and installed Cygwin, though I don't think I have enough space for all of it. I want to be able to run sshd so that my server PC can copy its daily backups over to the Cygwin PC, but every time I try to ssh from the server PC over to Cygwin, I get a Connection refused.

If you're just after 'sendmail compatibility' then both ssmtp and exim

I appear to have both exim and ssmtp installed; but I see that
/usr/sbin/sendmail is a symlink to /usr/bin/ssmtp. Fair enough, if
interesting.
I also see that my /etc/ssmtp directory is completely empty. Someone
on the list mentioned /usr/local/exim/README.Cygwin, but there is no
/usr/local/exim directory on my machine.
What I was trying to do was simply to send mail into our local Unix mail
system from a shell script in Cygwin.
When I tried using exim like this:
exim -oi luke /tmp/sample
I got this error:
set{u,g}id failed: 22
2004-07-14 10:48:44 unable to set gid=544 or uid=18 (euid=11021): privilege not needed
(Which I assume means the opposite: that some privilege *is* needed.)
When I tried using the ssmtp sendmail I got this error:
sendmail: Cannot open mailhub:25
which I assumed was because there was no ssmtp.conf file.
Is there a problem with Cygwin's install of ssmtp, in that it creates
no config? Or is configuration simply expected to be done locally or
manually? (From the man page, I see that there's supposed to be an
ssmtp.conf and a revaliases files, but not what they should contain).
BTW, I note that the man page for ssmtp mentions /usr/lib/sendmail,
which doesn't exist under Cygwin: /usr/sbin/sendmail does (good!).
I adapted Uwe Mayer's mail of Oct 6th last year, to produce an
ssmtp.conf file for our site:
root=admin
mailhub=smtp
rewriteDomain=cisra.canon.com.au
FromLineOverride=YES
The happy news to report is that following this, my simple mail
delivery test worked. I don't know what the /etc/ssmtp/revaliases file
is for, or what it should contain, but I thought I'd report these
problems and results in case they're of interest.

Building shared mod_php on cygwin + undefined symbols and missing DSOs
Hello, I'm trying to build the shared php libraries on cygwin but no success so far. Here's the configure invocation: ./configure --with-pgsql --with-apxs=/usr/sbin/apxs \ enable-cgi --enable-fastcgi I get this warning when running make: libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin shared libraries Since it's a warning, I just ignore it. However, I get this error when installing: $ make install Installing PHP SAPI module apxs:Error: file libs/libphp4.so is not a DSO make: *** [install-sapi] Error 1 There is no libphp4.so on the libs directory. Only these files. libphp4.a libphp4.la I've checked the cygwin archives regarding the issue and I saw these relevant posts: http://sources.redhat.com/ml/cygwin/2004-05/msg00212.html http://sources.redhat.com/ml/cygwin/2004-05/msg00269.html In the first post, the question was How to build php in cygwin. The responder pointed to a website. However, the several README.* files referred do not contain a reference to building php on cygwin (read: not even the string cygwin). I've searched the php site on relevant info regarding the problem. One link is: http://bugs.php.net/bug.php?id=21527 However, it still does not give us an idea on how to build php on cygwin. Further search on the net showed that there is an issue regarding using libtool with the -no-undefined option. I got the tip by entering the following string verbatim at google (except quotes): libtool: link: warning: undefined symbols not allowed in i686-pc-cygwin shared libraries Can anyone point out the way to build the latest php on cygwin?

Undefined reference errors and libtool
Hello, Maybe someone from the list can help me out. I'm trying to build a project that contains a number of executables, static and shared libraries using cygwin/autotools, but I'm having trouble with libtool. At certain point during the build, the linker returns an undefined reference error: ../lib/.libs/libopenmodeller.a(libenv_io_la-raster_gdal.o)(.text+0xa59): In function `_ZN10RasterGdal6createEPcR6Header': /home/ricardo/wcs/modeller/src/lib/env_io/raster_gdal.cpp:217: undefined reference to `_GetGDALDriverManager' The command that generated this error is: /bin/bash ../../libtool --mode=link g++ -g -O2 -o om_console.exe om_console-om_console.o om_console-occurrences_file.o om_console-request_file.o -L/usr/local/lib -lgdal ../lib/libopenmodeller.la which in turn runs this: g++ -g -O2 -o om_console.exe om_console-om_console.o om_console-occurrences_file.o om_console-request_file.o -L/usr/local/lib /usr/local/lib/libgdal.dll.a /usr/lib/libjpeg.dll.a -ltiff -lpng -lz -L/usr/lib -lpq ../lib/.libs/libopenmodeller.a -L/usr/local/lib -L/usr/local/lib Not sure why gcc doesn't find the symbols in libgdal.dll.a. nm says the symbol is there: [EMAIL PROTECTED] mailto:[EMAIL PROTECTED] ~/wcs/modeller/src/console $ nm /usr/local/lib/libgdal.dll.a | grep _GetGDALDriverManager T _GetGDALDriverManager I __imp__GetGDALDriverManager If I replace the library /usr/local/lib/libgdal.dll.a in the command above by -lgdal, I get my executable compiled.

Well, I get the segfaults *and* Reini's bug. Guess I'm just lucky!
You will have to debug the segfaults yourself. As for the source or the
Reini bug, this piece of code from fhandler_registry.cc looks
suspicious, in particular, the line marked with == (line 576):
else
{
bufalloc = 0;
do
{
== bufalloc += 1000;
filebuf = (char *) realloc (filebuf, bufalloc);
error = RegQueryValueEx (handle, value_name, NULL, type,
(BYTE *) filebuf, size);
if (error != ERROR_SUCCESS error != ERROR_MORE_DATA)
{
if (error != ERROR_FILE_NOT_FOUND)
{
seterrno_from_win_error (__FILE__, __LINE__, error);
return true;
}
goto value_not_found;
}
}
while (error == ERROR_MORE_DATA);
filesize = size;
}
I have a theory that the performance data may be added in chunks larger
than 1000 bytes, so the fhandler just can't keep up with the amount of
data, and loops indefinitely. Since you intend to build the DLL from CVS,
you're probably in the best position to check whether this theory is true
(by either just upping the increment amount to something like 5000, or
even doubling the buffer size on each iteration). If you can't do this,
I'll get to building the DLL tonight and do the above check.
Igor
Ok, the theory washed out. The code above is actually simply buggy. When
RegQueryValueEx is called (2 lines below the arrow), the size parameter
is uninitialized, so, in effect, it keeps thinking that the buffer has
some random size and reallocating (which, of course, doesn't change the
size, hence the infinite loop).
However, the fix is not as simple as inserting a size = bufalloc; just
before the RegQueryValueEx. When I do that, I get a SIGSEGV in the guts
of iasperf.dll, which I have yet to track down. This happens on the
second iteration, FWIW, with buffer increment of 1000. I'm going to
investigate some more, but I'd say that with the above bug, this key was
never tested, so I have no idea what's going on. Hopefully Chris
(January) can use this to help him track down the problem.

Re: dlopen under cygwin
Gerrit P. Haase wrote: Maarten wrote: Hi all, Is dlopen() friends supported under cygwin? If so, is the DLL that gets loaded using dlopen() a regular Win32 DLL, or a 'special' type of cygwin DLL? dlopen() works and one should use it. Reason I ask it that (while trying to get 'plugins' to work under cygwin) I had a look at the gmodule source code of glib, and it seems that gmodule uses regular Win32 LoadLibrary() calls to load the DLL, instead of calling dlopen(). I was wondering if that it actually correct. This seems to work too, but is it not portable, dlopen() is used for Linux applications and needs not to be ported when building with Cygwin, it just works the same way as for Linux. Except, as I mentioned before, cygwin's glib2 package is built in such a way that it, too, uses LoadLibrary directly and not dlopen. (IIRC, doing it right requires a patch to the gmodule stuff -- and I agree with the maintainer's decision to go ahead with the glib2 package rollout with LoadLibrary and delay the dlopen stuff until later, since I raised the flag on the issue so late in the game). I only mention this glib issue because the original poster had already indicated he downloaded and investigated glib...and I wanted to clarify why even the cygwin version currently uses LoadLibrary -- even tho Gerrit's statement that you should use it [dlopen] is correct. -- Chuck -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
