Here is one way to build a 64-bit Python binary on Solaris 10 using SUN's compilers**. This is probably not the recommended procedure but it does create a partial, expected result.
Here are the 4 steps I used: 1 - Run ./configure --without-gcc --with-cxx-main=CC --enable-64- bit .... 2 - Edit the generated Makefile and change 3 lines CC = cc -xtarget=opteron -xarch=amd64 CXX = CC -xtarget=opteron -xarch=amd64 MAINCC = CC -xtarget=opteron -xarch=amd64 The -xtarget and -xarch flags must be adjusted for UltraSparc. 3 - Edit python source file ./Include/pyport.h before line 728 (in Python 2.5.1) as follows. Add these 3 lines: #ifndef __GNUC__ /* non-GNU C/C++, like SUN */ # undef LONG_BIT #endif such that LONG_BIT is #define'd next #ifndef LONG_BIT #define LONG_BIT (8 * SIZEOF_LONG) #endif before this error message can occur #if LONG_BIT != 8 * SIZEOF_LONG /* 04-Oct-2000 LONG_BIT is apparently (mis)defined as 64 on some recent * 32-bit platforms using gcc. We try to catch that here at compile-time * rather than waiting for integer multiplication to trigger bogus * overflows. */ #error "LONG_BIT definition appears wrong for platform (bad gcc/ glibc config?)." #endif 4 - Run make and check the resulting Python binary with file ./ python. However, make test still fails and that will require further investigation. /Jean Brouwers **) Sun C/C++ 5.8 2005/10/14 on an Ultra 20 Opteron machine On Oct 29, 12:06 pm, MrJean1 <[EMAIL PROTECTED]> wrote: > Building 64-bit Python is still elusive.
