Windows build fails on MinGW GCC 13 due to libssp changes #51740
Closed
Description
Compiling Julia on Windows with GCC 13 from MSYS2 (which is the only available compiler) fails during linking:
LINK build2/usr/bin/libjulia-codegen.dll
C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/13.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: ./codegen.o: in function `add_named_global':
C:/Users/Tim/Julia/src/julia/src/codegen.cpp:549:(.text+0x26a53): undefined reference to `__imp___stack_chk_guard'
collect2.exe: error: ld returned 1 exit status
make[1]: *** [/c/Users/Tim/Julia/src/julia/src/Makefile:412: /c/Users/Tim/Julia/src/julia/build2/usr/bin/libjulia-codegen.dll] Error 1
make: *** [/c/Users/Tim/Julia/src/julia/Makefile:97: julia-src-release] Error 2
This is on #51698, because otherwise the CSL static libraries break the build.
I'm not entirely sure where we should be getting __stack_chk_guard from; it's defined in rtutils.c, but HAVE_SSP is set, so that code isn't activated:
Lines 218 to 228 in 4d2d849
Meanwhile, libssp.dll from CSL has the symbol:
❯ objdump -p ./usr/bin/libssp-0.dll | grep stack
[ 6] __stack_chk_fail
[ 7] __stack_chk_guard
... and we do link this DLL, but that somehow doesn't seem to help:

See below for a MWE, and the link to upstream changes causing this.
Workaround: override HAVE_SSP := 0 in Make.user.
