gcrypt windows build

When I compile on Windows XP using MinGW and GCC 4.4.1, and run the tests (make check), I get a bunch of failures:


FAIL: version.exe
FAIL: t-mpi-bit.exe
FAIL: prime.exe
FAIL: register.exe
FAIL: ac.exe
FAIL: ac-schemes.exe
FAIL: ac-data.exe
FAIL: basic.exe
FAIL: mpitests.exe
FAIL: tsexp.exe
FAIL: keygen.exe
FAIL: pubkey.exe
FAIL: hmac.exe
FAIL: keygrip.exe
FAIL: fips186-dsa.exe
FAIL: benchmark.exe
========================================
16 of 16 tests failed
Please report to bug-libgcrypt [at] gnupg
========================================


The libraries build just fine - no problems there. When I run the programs I don't see any output at all. Any thoughts? I appreciate any help anyone can provide.

We only support cross-builds from a POSIX platform. If you try to
build it on the traget platform it may or may not work.

You mean the test program? They return an exit code; some of them
accept an option like

cd tests
./basic --verbose

How do you test a cross-compiled library? How do you run your test programs to validate your cross-compiled libraries are working correctly? Do you have any tips on how I could get the test programs working?

I was running the generated executables (e.g. ./basic.exe --verbose), not the associated scripts (./basic) and even with --verbose, I was getting no output at all.

Thanks for helping me out - it's appreciated.

Use wine. Just install MinGW and Wine under Linux, and then build
libgcrypt like this:

./configure --host=i586-mingw32msvc --build=i686-pc-linux-gnu

It will invoke the self-tests automatically, if you have the
binfmt-support package installed.

If you want a makefile that does everything, check out
<http://josefsson.org/gnutls4win/Makefile>.

What version of gcc do you use (in the mingw toolchain)?

I'm using the 'mingw32' package from debian, which appears to be gcc 4.2
based. http://packages.qa.debian.org/m/mingw32.html

Take care: The mingw packages in Debian are broken:

as GNU make. We are using Debian GNU/Linux (Lenny); due to a little
bug in the mingw32 compiler it is highly suggested to put a line
deb http://apt.intevation.org lenny/mingw .
into /etc/apt/sources and update the mingw packages.

they replaced the snprintf and introduced a bug. IIRC, "%lu" requires
an "unsigned long long" arg and not an "unsigned long". The result is
that the stack is messed up and you get all kinds of strange error.
At one point it took us many hours of debugging until we realized that
some parts of a system were build with the broken mingw runtime. The
fix is trivial but still hasn't made it into Debian.

I think libgcrypt does not use printf with "%lu" but that may depend
on the version.


Shalom-Salam,

Werner

Interesting! I believe I was able to reproduce the problem, now
reported too:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=561599

There is another bug report as weel. Hwoever I can't remember the
number. FWIW, here is a little test program:


#include <stdio.h>

main ()
{
unsigned long foo = 42;
char buf[50];

snprintf (buf, sizeof buf, "->%lu<-", 42);
if (strcmp (buf, "->42<-"))
{
fputs ("snprintf is broken\n", stderr);
return 1;
}
else
{
fputs ("snprintf is okay\n", stderr);
}
return 0;
}



Shalom-Salam,

Werner

It is http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=452977 -- my bug
was a duplicate of that one.

Looks like the same error.
