Greeting,
I am trying to install numpy on the same system into to different prefixes, one dedicated to 32 bit stuff and the other to 64 bit. The machine is a dual CPU Core 2 Duo machine, that is a 64 bit native machine. Getting the 64 bit version to work is no problem. But cross compiling numpy for 32 bit binaries is very troublesome. I have compiled all the dependences using "-m32" including Python itself. All my other packages compile using the -m32 flag without problems. I have set CFLAGS, LDFLAGS, BASECFLAGS, CPPFLAGS, and CXXFLAGS all to reflect the change in bits to use. Please find below the error I receive when compiling with: python setup.py build --fcompiler=gnu95. The error appears to be because it is trying to link _configtest.o without the -m32 flag and thinks it is making a 64 bit binary. If I edit line 378 of ccompiler.py to add "-m32" to the link_opts by hand I can get past this error to a new one which indicates that main was never declared in the linalg package. If that is the more useful starting point I can post those errors as well. Any help would be greatly appreciated. Regards, Brian ############### ERROR BELOW ##################### C compiler: gcc -pthread -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict- prototypes -m32 -m32 -fPIC compile options: '-I/rh5stuff/32bit/include/python2.6 -Inumpy/core/src -Inumpy/core/include -I/rh5stuff/32bit/include/python2.6 -c' gcc: _configtest.c gcc -pthread _configtest.o -L/rh5stuff/32bit/lib -L/usr/local/lib -L/ usr/lib -o _configtest /usr/bin/ld: skipping incompatible /usr/lib/libpthread.so when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/libpthread.a when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/libc.so when searching for -lc /usr/bin/ld: skipping incompatible /usr/lib/libc.a when searching for - lc /usr/bin/ld: warning: i386 architecture of input file `_configtest.o' is incompatible with i386:x86-64 output _configtest failure. removing: _configtest.c _configtest.o _configtest _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
