tag 317146 + patch thanks I have now tested the patch from Launchpad[0] and can report a partial success! libgcc works:
$ i586-mingw32msvc-g++ -shared-libgcc -o shared.exe hi.cpp
$ i586-mingw32msvc-objdump -p shared.exe | grep 'DLL Name'
DLL Name: KERNEL32.dll
DLL Name: msvcrt.dll
DLL Name: msvcrt.dll
DLL Name: libgcc_sjlj_1.dll
$ wine shared.exe
hi
But libstdc++ does not:
$ i586-mingw32msvc-g++ -shared-libgcc -o shared.exe hi.cpp -lstdc++_s
$ i586-mingw32msvc-objdump -p shared.exe | grep 'DLL Name'
DLL Name: KERNEL32.dll
DLL Name: msvcrt.dll
DLL Name: libstdc++_sjlj_6.dll
$ wine shared.exe
wine: Unhandled page fault on read access to 0xfffffff4 at address
0x6ce4f585 (thread 0009), starting debugger...
Usage:
winedbg [ [ --gdb ] [ prog-name [ prog-args ] | <num> |
file.mdmp | --help ]
I have attached the debdiff (modified to apply to the current package in
Debian) to this message.
I have also attached a test case to demonstrate that the patch works. If
you have the patched mingw32 package installed then you can simply run
'make' and then run both of the generated exe files under wine. Without
the patched package, you can only build the static exe with 'make
main-static.exe'.
