Dear list,
I am struggling a little with a recent revision of the MinGW-w64 runtime. I use
the latest snapshot from openSuse to install my cross-compiler tool chain. I
used Qt4 in the past and want to migrate to Qt5. During this process I
experience the following issue:
In my project I link against MSVCR110.DLL and other libs from Microsoft SDKs.
For example against RUNTMCHK.LIB from Visual Studio 2012. When linking the
executable I get the following error:
runtmchk.lib(f:/dd/vctools/crt_bld/SELF_64_amd64/crt/src/build/amd64/dll_obj/nativec/gs_report.obj):(.text[__report_gsfailure]+0x0):
multiple definition of `__report_gsfailure'
/usr/x86_64-w64-mingw32/sys-root/mingw/lib/libmingw32.a(lib64_libmingw32_a-gs_support.o):/home/abuild/rpmbuild/BUILD/mingw-w64-crt/crt/gs_support.c:104:
first defined here
Seems that MinGW tries to provide some functionality that was used to be
provided by runtmchk.lib. I still need this lib, however, since MinGW-w64 only
supports a little subset from there. Now my question to you: What steps would
you recommend to solve this issue?
What I did here was: I recompiled the MinGW-w64 runtime and removed the
function report_gsfailure from the runtime. In this case, however, my
executable crashes during initialisation of Qt5 on Windows 7 and in Wine. Hence
I guess this was not the optimal solution attempt.
Best regards
Sebastian
