New submission from Charles Solar <charlesso...@gmail.com>: On solaris, if you build a 64 bit python and use it to build an extension, it will not properly link the module.
Apparently solaris requires the -m64 flag in the linker as well as the compile steps. Python distutils successfully compiles all the object files using -m64, but it fails to link with -m64 causing the entire build to fail if the extension needs a 64 bit library dependency ( will get 'incompatible library' errors from the linker ). To reproduce: build python with CFLAGS="-m64 -O3" LDFLAGS="-m64" build a C extension that depends on a 64 bit library (python setup.py install) I assume that it would work if the C extension does not need a specific 64 bit library as the linker will not go and look for the wrong version of file. So its a very uncommon but annoying bug. > ld --version GNU ld (GNU Binutils) 2.20.1.20100303 Copyright 2009 Free Software Foundation, Inc.
