All,

When I configure python to enable shared libraries, none of the extensions
are getting built during the make step due to this error.

building 'cStringIO' extension
gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall

-L/usr/local/lib *-lpython2.6* -o build/lib.aix-5.3-2.6/cPickle.so
*collect2: library libpython2.6 not found*

This is on AIX 5.3, GCC 4.2, Python 2.6.6

I can confirm that there is a libpython2.6.a file in the top level directory
from where I am doing the configure/make etc

Here are the options supplied to the configure command

./configure --enable-shared --disable-ipv6 --with-gcc=gcc CPPFLAGS="-I
/opt/freeware/include -I /opt/freeware/include/readline -I
/opt/freeware/include/ncurses"

Please guide me in getting past this error.

Thanks for your help on this.

Regards,
Anurag
