gcc: problem with scanf/printf with 64 bit integers on cygwin with -mno-cygwin
I use the type unsigned long long and long long to get 64 bit integers on gcc. For reading and writing I use the formatting e.g. unsigned long long u64; u64 = ...; printf(a 64 bit integer %llu\n, u64); This has worked up to now on all systems using gcc except on cygwin compiling with the option -mno-cygwin and on mingw. I get the following problems: - If I print a 64 bit integer alone, the output is ok, if I print 64 bit and 32 bit integers with the same print statement, the output is not the content of the integers. - If I scan a 64 bit integer and the corresponding and the variable into which I read is not initialized, the input is not correct. Is this problem known? Unfortunately the problem is within a big program. But if needed, I could try to isolate it in a small program. But I don't know, if the problem is deterministic, so I cannot promise that.

Re: GCC: problem with library search path when targeting mingw
I'm not sure that I agree with your assements, /usr/lib as always been available (at least displayed) as a default search path in 'print-search-dirs' even when using the -mno-cygwin switch, but for some reason, has always been ignored when linking for MinGW. I think the problem has to do with '/usr/lib/gcc/i686-pc-mingw/3.4.4/../../..' in the search paths, I'm not sure if this path was available in the previous packages of gcc/mingw-runtime/binutils (I don't feel like downgrading to check it out :) ), but this is the one that's giving me trouble rather than /usr/lib, so I don't think -Wl,-nostdlib will be of any help. I agree with you that -mno-cygwin has been a bad choice, as it requires a lot of hacking around to get some configure scripts to recognize/use this option when cross-compiling autotools based packages for MinGW, but until this recent problem, I've always managed to get by without tweaking configure scripts, typically overriding CC, CXX, CPPFLAGS, etc... on the command line was enough. Damien Christopher Faylor wrote: Thanks for the report. This has been mentioned before, it's a problem in gcc's 'specs', which are command-line pattern matching strings (more-or-less) used by the gcc compiler driver to select the right options for the sub-programs that it invokes. It's basically a consequence of the fact that we're using the same driver to drive a native compiler /and/ a cross-compiler; normally, a cross-compiler wouldn't include any of the system paths such as /usr/lib at all, but for a native compiler that's exactly what you want it to do. The /usr/lib inclusion is actually likely to be a binutils problem since ld includes /usr/lib by default. Possibly adding -Wl,-nostdlib to the command line would help. In any event, I really think that -mno-cygwin is 1) a bad choice for an option name and 2) a bad way to accomplish what is essentially cross-compilation. I regret that I stood by idly and watched that option go into gcc. cgf Damien Fouilleul wrote: hello, I'm a big fan of cygwin and I use it a lot to compile mingw apps, however with the latest mingw-runtime, I'm having trouble running configure scripts successfully as test such 'dlopen() in -ldl', which used to fail for mingw target (as expected) now succeeds.

Larry,
Thanks for your quick reply!
I installed the latest version of Cygwin, and almost
all packages which includes 'binutils' package. I
checked and found 'ld' in the path: (1)
cygwin\bin\ld.exe (678 kb), and (2)
cygwin\usr\i686-pc-cygwin\bin\ld.exe (1 kb). Is this
normal?
Yes, that's normal. The latter is a symbolic link to the former.
I did a quick search on the list and couldn't find
exact answer to my question.
Do you have any more thoughts? Thanks!
OK, this looks like it must be a configure problem then. 'cygpath'
is apparently being invoked by the script with an empty path. If
you can narrow down where in this script that this is happening,
you should have more luck determining why this is the case and how
to resolve it. My WAG is that it's resolving some environment variable
or path that doesn't actually exist. But I can't say more without
further details.
HTH,

Re: Help: gcc problem in Cygwin!
Frank, you could run make with the -n flag to see what commands it issues (even hidden command lines). This generates enormous amounts of output for all commands far beyond the one that is bothering you now, so run for instance: make -n 21 | less If you're lucky, you'll see cygpath mentioned early on. If you're very lucky, the context would tell where to look further. -- Stein -- 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/

that there is a confusion on which linker to use
for
gcc, and GNU ld is not on the path. I attach the
output from './configure' at the end. Do you think
it
is related to those outputs? If so, how to fix it?
If
not, what's the cause?
checking for ld used by GCC... ${CXX}
checking if the linker (${CXX}) is GNU ld... no
Make sure you've installed the 'binutils' package
and that
'ld' from this package is in your path. If this
doesn't
resolve the problem, then please read and follow the
problem

Re: gcc problem - cygwin-1.5.19-4
Hello, It's not a flag problem: sometimes when I invoke make this problem happens and the, 1 or 2 seconds after, if I invoke again make, it works fine without any modifications. I have never meet this problem with the preceding version of cygwin. It happened since 1.5.19. Could it be a transient network problem ? Your sincerely, Yann COLLETTE Gerrit P.

gcc problem
Hi Gents,
I've installed the latest version of cygwin (as of today 2.03.04). My PC is
running Windows 2000 with service pack 4. Installation is done on my loca
drive d:. I tried a small C++ and failed, the reason is totally unclear to
me.
The program is:
#include iostream
using namespace std;
int main()
{
int selection;
bool loop = true;
while (loop)
{
#if 0
cout endl;
cout *\n;
cout * Learning bed C++ *\n;
cout *\n;
cout CHAPTER 4 \n;
cout =\n\n;
cout 1: Review_5\n;
cout -1: Exit\n;
cout $ ;
cin selection;
cout endl;
switch (selection)
{
case -1:
loop = false;
break;
case 0:
break;
case 1:
break;
case 2:
break;
case 3:
break;
case 4:
break;
case 5:
break;
case 6:
break;
case 7:
break;
case 8:
break;
case 9:
break;
case 10:
break;
case 11:
break;
}// switch (selection)
#endif
}// while (loop)
return 0;
}//main
The error message is:
$ gcc -o gtest gtest.cc

same.

Gareth PS - in response to the other email - .cc Is pre-processor input - since that's the Normal state for c++ code - pre-processor input of which the output is then fed to a c++ compiler. (Virtually at least, in practice it can end up being integrated somewhat. The C standard allows 'as if' interpretation in the implementation of the pre-processing component.) -- 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/

1.3.22: (gcc) problem using gettimeofday with -mno-cygwin
Hello,
I am trying to compile the following trivial program:
#include stdio.h
#include sys/time.h
int main()
{
struct timeval tv;
gettimeofday(tv, NULL) ;
printf(%ld %ld\n, tv.tv_sec, tv.tv_usec);
return 0;
}
When I use gcc with no options, everything works fine. However, if I use

gcc problem with filename case insensitivity
Greetings,
I have a problem which I realise comes from Windows' being
case-insensitive with filenames. Even so, maybe someone here knows
how to solve it.
Suppose I have this source file:
#include string.h
#include String.h
int main() {
// some stuff
}
and I compile with gcc -Imy/include/dir sourcefile.c where
String.h lives in my/include/dir.
GCC uses my/include/dir/String.h to satisfy the string.h directive.
Is there any way to get GCC to check case when locating include files?
Interestingly, this used to work in B18! (Hahaha!)
Seriously, though, the B18 release announcement has this remark:
The conflict between String.h and string.h (and other such pairs of
header files) where you include one and get the other has been fixed.
(describing gcc in the release).
A Google search on filename case gcc site:cygwin.com turned up only
10 hits, and the B18 release announcement was one of them. :-)
Is there any possibility to get case-sensitive behavior from GCC in
this respect?
Thanks,
David

Re: gcc problem?
I didn't program in C for a long time but as far as I remember,
scanf read 1 string using white space as separator.
to enter aaa bbb ccc
you need scanf(%s %s %s, ...) or gets
use gets
or scanf(%s, ..)
followed by
while('\n'!=getchar());
but you loose the extra typed words
hope this helps.

You can't flush(stdin). Nothing wrong with Cygwin here, simply the other

Flushing stdin (was: Re: gcc problem?)
Carlo,
Visual C++ 6.0 CRT (and AFAICT, that of Visual C++.NET too) allow you to
flush an input stream. The only problem with that is that the C standard
apparently defines flushing ONLY for output streams (sec. 7.9.5.2). Why in
the hell MicroSquash didn't disclose that this behavior was M$-specific, who
knows--it's yet another way they try to lock you into their software.
For reading words entered by the user, I'd approach the situation using
fgets() and a pair of string buffers--one to hold the input line and one to
hold the word that is sscanf()'ed. After we've read the word, we can
loop-read until there are no more characters on stdin (in case we entered
past the size of the string buffer), knowing that our word is in a separate
buffer and that each iteration both are NULLed out.
Here's the code...
#include string.h
#include stdio.h
int main() {
char string[80];
char word[80]; /* extra string buffer */
int i;
for (i = 0; i 2; i++) {
memset(string, 0, 80 * sizeof(char));
memset(word, 0, 80 * sizeof(char));
printf(Enter some words: );
fgets(string, 80, stdin); /* see note A */
sscanf(string, %s, word);
printf(The first word you entered was... %s\n, word);
while (!strchr(string, '\n'))
fgets(string, 80, stdin);
}
return 0;
}
Note A:
Pressing Enter as soon as the prompt comes up will cause fgets() to write a
newline and a NULL to the buffer and return. If you want to FORCE the user
to enter a non-blank line, then change
fgets(string, 80, stdin);
to
do {
fgets(string, 80, stdin);
} while (string[0] == '\n');

RE: Flushing stdin (was: Re: gcc problem?)
I believe the name of the company you're referring to is Microsoft. (In
addition to the spelling, note that the 's' is not capitalized.) It
matters, because you'll have a much easier time reporting the small bug
you've discovered (these do occur in large systems, and the
documentation for large systems) if you use the correct company name
when searching for a web site on which to actually submit the bug
report.
BTW, which C standard do you mean? 7.9.5.2 doesn't seem to exist in
either of my copies (I have the 1989 ANSI version, and the 1999 ISO
version handy).

RE: gcc problem?
This is not a bug in Cygwin or Gcc. Scanf(%s, ...) only reads from
the stdin if the input buffer is empty. If you only enter a single word
on the first prompt, then it will wait for you to type the 2nd word. If
Borland produces different results then maybe they are wrong (or simply
different).
