Re: unable to compile Python 2.6.4 on AIX using gcc
[In reply to]

Thanks Mark. That was indeed very helpful. Here's the current status:
=======================
1. applied changes suggested by Bob Atkins in that thread.
2. setting env variables.
export OBJECT_MODE=64
export CC="gcc"
export CFLAGS="-maix64 -mcpu=power5"
export LDFLAGS="-maix64 -L/usr/lib64 -L/opt/freeware/lib64
-L/opt/freeware/64/lib -L/usr/X11R6/lib -L/opt/freeware/lib"
export CPPFLAGS="-I/opt/freeware/include -I/usr/lpp/X11/include/X11"
3. configuring and compiling using
configure --with-gcc --enable-shared --prefix=/usr/local/Python-2.6.4 >
config_264.log 2>&1 ; make > make_264.log 2>&1
=======================
Both python (executable) and libpython2.6.a build just fine and are in
the same directory as configure.
However, none of the extensions build. I keep getting libpython2.6 not
found error. Here's an example:
building 'math' extension
gcc -pthread -fno-strict-aliasing -maix64 -mcpu=power5 -DNDEBUG -O3
-Wall -Wstrict-prototypes -I.
-I/usr/local/build/python/Python-2.6.4/./Include -I. -

collect2: library libpython2.6 not found
I hacked Makefile to
LDFLAGS= <> -L./ <other flags>
I now get:
ld: 0711-224 WARNING: Duplicate symbol: PyObject_Size
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more
information.
Fatal Python error: Interpreter not initialized (version mismatch?)
make: The signal code from the last command is 6.
There are no other versions of python on that machine. I would
appreciate any help. Do I need to set the exec_prefix as well?
Thanks.
