Summary: libpython2.4.so get not installed
Initial Comment:
Given:
AIX 5.1
GCC 3.3.2
Python 2.4.2 ( Python-2.4.2.tar.gz )
./configure \
--enable-unicode \
--enable-shared \
--with-gcc \
--mandir=/usr/local/man \
--infodir=/usr/local/info
Problem:
during " gmake install " the libpython2.4.a will not
be installed in /usr/local/lib and the link for
libpython2.4.so does not exist then.
I did not dig further but below is the output from
"gmake install"
For me the
...
if test -f libpython2.4.so; then ...
look wrong because it does not contain a Path and will
fail.
regards
Hajo
output during "gmake install"

Hi Neal
if give up to test/fix the configure.in With the help from
Ulrich Berning i build a static version and convert these to
a shared one. See notes down below.
Tnx for supporting

The problem seems to be in configure.in. Search for
Py_ENABLE_SHARED. Try adding a line for LDLIBRARY (like for
BeOS). You may also need a line for INSTSONAME and others
variables too. After modifying configure.in, you will need
to regenerate with autoconf. You can try modifying
configure which is generated by autoconf. Then re-run
configure. Search for libpython in the generated Makefile.
That should have a .so ending.

Its looked like that the libpython2.4.so will not be build.
I took a lock at the Makefile but could not get a clear view
what option is needed to let the system build a libpython2.4.so
