Hi
Just to correct my previous message, the alternative stralign.h I
found doesn't work for me after all when building Ninja, I made a mistake
building it before to think it did work.
So the diff I provided for further info in my previous message may not be
that useful
So to recap, I'm using stralign.h from here:
http://sourceforge.net/projects/mingwbuilds/files/host-windows/releases/4.8.1/64-bit/threads-win32/seh/
that fails on stralign.h:
#ifndef __CRT__NO_INLINE
__CRT_INLINE PUWSTR_C ua_wcschr(PCUWSTR String,WCHAR Character) {
if(WSTR_ALIGNED(String)) return ::wcschr((PCWSTR)String,Character);
return (PUWSTR_C)uaw_wcschr(String,Character);
}
__CRT_INLINE PUWSTR_C ua_wcsrchr(PCUWSTR String,WCHAR Character) {
if(WSTR_ALIGNED(String)) return ::wcsrchr((PCWSTR)String,Character);
return (PUWSTR_C)uaw_wcsrchr(String,Character);
}
I added the :: characters above to make Ninja compile, but I doubt that is
the right fix even it works or appears to.
If there exists a "latest" release of these files, please give me a full
link to where and I'll try them and report back.
Alternatively, if anyone else want's to try to build Ninja on github with
libcxx and clang++ using the same mingw's C headers I am using,
then they should see the same conflict I am seeing with libcxx's headers
and mingw's stralign.h that I'd like to fix.
Until someone with more experience than me tries that, I'm stuck wrestling
with it. But here's the clang++ output from compiling with that setup:
