I am feeling next to it - no one of 'make' ports I tried (Compiled from
the MSYS trunk, Migw32, Migw64, TDM-GCC) handle multiple jobs correctly.
There is likely an old bug causing make to freeze randomly when -jN with
N>1 is passed to it. (I found reports with similar problem in MinGW
the possible reasons, but no workaround; even found a patch from a user
that should fix this, but got another errors when used 'make', compiled
with this patch).
A good idea, thanx! I'll try to use cmake instead of configure. May it
produce makefiles that mingw32-make.exe from MinGW64 accept.
mingw32-make.exe is my last hope on a simple solution, but currently it
ends up with (renamed mingw32-make.exe to make.exe) :
make -j8 ONLY_TOOLS="clang" ENABLE_OPTIMIZED=1
Makefile:141: /f/llvm_COMMON/Makefile.rules: No such file or directory
make.EXE: *** No rule to make target `/f/llvm_COMMON/Makefile.rules'. Stop.
, while 'make' from MSYS build without errors (but hangs randomly).
MS2012 builds+tests for 20 minutes, but I want MinGW to also work :)
Morover, it produces Clang, that is unable to link files due to
(the problem is likely related to name mangling issues
and that's that!
