FW: Problems compiling grep and friends
Im running xp pro and I am trying to compile grep. I downloaded the source. ./configure seemed to go OK but there were problems with make. It looks like it cannot find the usr directory.

It looks like it cannot find the usr directory. Is there a fix for this? How did you configure? It looks like it's got confused over the --prefix setting; that extra '/' then makes cygwin treat the path as a UNC network path, so you're trying to install to a network share called 'local' on a remote host named 'usr'! I've seen this sort of thing happen before when I was messing around by setting DESTDIR during make install. You'd better show us all your configure and build command lines. mkdir //usr mkdir: cannot create directory `//usr': No such host or network path mkdir //usr/local mkdir: cannot create directory `//usr/local': No such host or network path mkdir //usr/local/share mkdir: cannot create directory `//usr/local/share': No such host or network path make[1]: *** [install-data-yes] Error 1 make[1]: Leaving directory `/cygdrive/c/Documents and Settings/sheintze/Desktop/ftp%3a%2f%2fmirrors.kernel.org%2fsourceware%2fcygwin /release/grep/grep-2.5.1a-4/po' make: *** [install-recursive] Error 1 I really wouldn't build it in your package dir though, that's a bit cluttery. The optimal method is to use setup.exe to download and unpack the source for grep into /usr/src, and build it there (using the provided build script if there should happen to be one). cheers, DaveK -- Can't think of a witty .sigline today -- 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/
strange behavior with perl v 5.8.8
Hello,
I've run into a strange adding problem with perl:
when incrementing by 0.1 i get a strange behavior where at some
arbitrary number, it will append 0.99 to the end of the
number.
test case:
my $start = 0;
my $interval = 0.1;
my $end = 10;
do{ print start: $start\n; $start += $interval;}until($start = $end);
Results:
...
start: 4.5
start: 4.6

why all of suddun i get 5.9?
Is this a perl problem?

Re: strange behavior with perl v 5.8.8
Nope, not a Cygwin specific issue.
I get the same behavior at the same point on Gentoo perl 5.8.8 (x86
dual-Xeon), Debian Etch perl 5.8.8 (x86 P4), and SunOS 5.10 perl 5.8.4.

'fraid so. Use rounding if you like. This is bog-standard floating point behaviour, part of the fundamental limitations of the representation. See, e.g. http://docs.mandragor.org/files/Programming_languages/C/clc_faq_en/C-faq/q14.1 .html http://en.wikipedia.org/wiki/Floating_point#Accuracy_problems or in general google for floating point accuracy. cheers, DaveK -- Can't think of a witty .sigline today -- 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/

Because binary floating-point numbers can't represent decimal values
like 0.1 exactly.
Is this a perl problem?
No, it's not a Cygwin problem either. It's a floating-point problem. We
have to deal with such queries all the time in the Python community:
http://www.python.org/doc/faq/general/#why-am-i-getting-strange-results-with-simple-arithmetic-operations
[...]
The correct way out of this is to use integer variables to control the
loop and calculate the start value each time around.

Steve

supposed missing iconv with cygwin 1.7.0
When building binutils with cygwin 1.7.0 cvs and snapshot, make reports that iconv is missing. I think it also happens with gcc. This was captured from cygwin's bash. Is this a known issue? The only solution I could come up with is installing a new libiconv, but the current libibiconv is from 2006. This has made me hesitant about trying the new dll. It compiles fine under cygwin 1.5.24-2, the current dll. snip [EMAIL PROTECTED] ~/binutils $ mkdir obj [EMAIL PROTECTED] ~/binutils $ cd obj [EMAIL PROTECTED] ~/binutils/obj $ CFLAGS=-O2 ../src/configure checking build system type... i686-pc-cygwin checking host system type... i686-pc-cygwin checking target system type... i686-pc-cygwin checking for a BSD-compatible install... /usr/bin/install -c checking whether ln works... yes checking whether ln -s works... yes checking for gcc... gcc checking for C compiler default output file name... a.exe checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... .exe checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ANSI C... none needed checking for g++... g++ checking whether we are using the GNU C++ compiler... yes checking whether g++ accepts -g... yes checking for gnatbind... gnatbind checking for gnatmake... gnatmake checking whether compiler driver understands Ada... yes checking how to compare bootstrapped objects... cmp --ignore-initial=16 $$f1 $$f 2 checking for bison... bison -y checking for bison... bison checking for gm4... no checking for gnum4... no checking for m4... m4 checking for flex... flex checking for flex... flex checking for makeinfo... makeinfo checking for expect... expect checking for runtest... runtest checking for ar... ar checking for as... as checking for dlltool... dlltool checking for ld...

Insight - redirect from stdin?
I want to use insight with a source file redirected from stdin. I suspected that I should have to bring up the gdb console window and type: run myfile But this doesn't appear to do anything other than run the program directly. If I run it using the input console and type things in, it works fine. I am using cygwin.dll 1.5.24-2, with all files downloaded 8/21/2007.

bug in Win32 Cygwin setup.exe
In order to install Cygwin, I must use either the IE5 settings or a proxy. Upon running the setup.exe program, if I click on Use IE5 settings first, then I have no problem; it finds the mirrors, and I'm golden. If I click on Direct Connection and it fails, I click Back, and then click on Use IE5 settings, then it does not find the mirrors, and even when I add them manually, it won't find the appropriate setup files.
