Hi all,
I'm currently trying to build an ARM cross-compiler that supports
OpenMP under Cygwin (release version 1.5.25-15). For this I took the
gcc-4.2.4 and configured the system in the following way (see the
whole build approach below):
../gcc-4.2.4/configure --target=arm-elf --prefix=/usr/cross/
--with-gnu-as --with-gnu-ld --with-newlib
--with-headers=/usr/cross/arm-elf/include --enable-libgomp
Unfortunately the build stops with the following error message (BTW:
The same error occurs taking the latest gcc-4.3.2):
[...]
checking what to include in gstdint.h... stdint.h (already complete)
configure: error: Pthreads are required to build libgomp
make[1]: *** [configure-target-libgomp] Error 1
Therefore I tried the '--enable-threads=lib' option whereas I first
took '--enable-threads=win32' and then alternatively
'--enable-threads=posix'. But both options ran into errors with the
"gthr-win32.h" and the "gthr-posix.h" respectively (see details
below).
I'd be thankful for any hint I can get to make the compiler run!
Thanks in advance!
BR,
Sebastian
