问题
On compiling GOBJECT in Visual Studio, I came across below two errors:
Error 5 error LNK1120: 1 unresolved externals C:\gtk_compilation\glib\glib-2.46.0\build\win32\vs12\Debug\Win32\bin\gobject-2-vs12.dll gobject
Error 4 error LNK2019: unresolved external symbol ___chkstk_ms referenced in function _ffi_call C:\gtk_compilation\glib\glib-2.46.0\build\win32\vs12\libffi.lib(ffi.o) gobject
I recompiled the libffi using the procedure described here but with
extra flags given to ./configure like below.
cflags="-fno-stack-check -fno-stack-protector -mno-stack-arg-probe"
which i hope will get rid of the ___chkstk_ms invocations.
After make and make install of libffi, I renamed the libffi.a to libffi.lib and libffi.dll.a to libffi.dll and copied them to appropriate directories.
Then I re-build the gobject project in visual studio and I got the same error which I mentioned in the beginning. :(
Edit:
From this post, I guess the problem's root is that I am using two compilers. But i don't see a way to get around it. I tried to compile the libffi using Visual Studio Projects available, but hours of efforts were in vain.
回答1:
I resolved this using the MSVC build of Libffi found in the Github project.
However, you need to change the line#606 from
sizet z = (*p_arg)->size;
to
unsigned long long z = (*p_arg)->size;
because the typedef is not (for some reason effective here).
