I had a lot of problems with gcc 4.2.x mingw cross (which I used for other
occasions) building mono 2.4 . Then I looked up what the build farm use, and it
is 3.4.5. Seems that gcc 4.2.x is not happy with some of the code when cross
compiling, or when building for windows. I don't know what gcc is available
under cygwin, so I cannot say if the problem is there or not. Rebuilding and
downgrading my cross-compiler to 3.4.5, I managed to cross-build mono 2.4.
Here are a few examples of problems - it is not happy with GC_WIN32_THREADS
being defined both in command line and in code defines. Not happy with FARPROC
in line 479 of libgc/misc.c:
(FARPROC) pfn = GetProcAddress(hK32,
"InitializeCriticalSectionAndSpinCount");
Not happen with the syntax of pointer increment around line 1260
mono/metadata/image.c:
((guint32*) slot)++;
((guint64*) slot)++;
I think these were warnings in gcc 3.4.x and becomes errrors in 4.2.1
Reproducible: Always
Steps to Reproduce:
1. try building with gcc 4.2.1 mingw cross.
Actual Results:
compiler errors.
Expected Results:
successful compilation.
