AIX 5.3 - Enabling Shared Library Support Vs Extensions

[Anurag Chourasia]

Hi Stefan,

I followed your suggestion and configured LDFLAGS but the make step fails
for another error now.

My configuration options are as follows

./configure --enable-shared --disable-ipv6 --with-gcc=gcc CPPFLAGS="-I
/opt/freeware/include -I /opt/freeware/include/readline -I
/opt/freeware/include/ncurses" LDFLAGS="-L. -L/usr/local/lib"

Below is the transcript from the make step.

running build
running build_ext
ldd: /lib/libreadline.a: File is an archive.

*Fatal Python error: Interpreter not initialized (version mismatch?)*
*make: 1254-059 The signal code from the last command is 6.*
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

The last command that i see above (ld_so_aix) seems to have completed as the
file _struct.so exists after this command and hence I am not sure which step
is failing.

There is no other Python version on my machine.

Please guide.
