Undefined reference to `__chk_fail'

[ajpenner]

Description / Steps to reproduce the issue

We are attempting to build our source code with code coverage enabled. During the linking phase we hit: C:/msys64/mingw32/bin/../lib/gcc/i686-w64-mingw32/13.2.0/../../../../i686-w64-mingw32/bin/ld.exe: C:/msys64/mingw32/bin/../lib/gcc/i686-w64-mingw32/13.2.0/libgcov.a(_gcov.o):(.text+0x17a1): undefined reference to `__chk_fail'

I am uncertain which packages/libraries I need to include to get this working. I have read posts from 5 years ago suggesting that we need to explicitly add '-lssp' or -fstack-protector, neither of these options worked. Likewise using -D_FORTIFY_SOURCE=0 was not a solution.

I am using the latest mingw packages for gcc (13.2.0-3)

Expected behavior

The linker to successfully produce a binary

Actual behavior

The linker cannot produce a binary because of a missing definition

Are you willing to submit a PR?

I am willing to, but I need to know where the problem comes from.

[Biswa96]

Could you provide any minimal sample to reproduce the same error?

[ajpenner]

I will see what I can do about that. The code causing the problem at the moment is proprietary, I will be free to provide a sample in a week or so.

Thanks for the quick response.

[lazka]

'-lssp' or -fstack-protector

-lssp no longer does anything since that code is now included in mingw-w64 and we just provide an empty static archive so it doesn't error, and -fstack-protector doesn't change anything linker related I think (not sure).

The error seems to be related to gcov, so maybe try building without gcov intrumentation as a test (remove -fprofile-arcs -ftest-coverage --coverage etc)

No idea, somehow it's not linking in the mingw-w64 provided things.

[ajpenner]

@lazka I did try a test without the gcov instrumentation and the build worked as expected. I agree that this is isolated to gcov.

[ajpenner]

Sorry about the long delay, please find below a minimal sample of the problem cat sample.c

#include <stdio.h>

int main(int argc, char* argv[])
{
    printf("Hello World");
    return 0;
}

gcc -v -fprofile-arcs -ftest-coverage sample.c

Using built-in specs.

[Biswa96]

I can not reproduce the issue with a clean msys2 installation. Please try with a clean msys2 installation and update the packages.

[ajpenner]

The issue is not with gcc compiling, it is with adding the gcov. I agree that simply running gcc on the code works as I would expect

[Biswa96]

I can not reproduce the issue with gcc -v -fprofile-arcs -ftest-coverage sample.c command also.
