2.4.2 on AIX 4.3 make fails on threading

[Paul Watson]

When I try to build 2.4.2 on AIX 4.3, it fails on missing thread
objects. I ran ./configure --without-threads --without-gcc.

Before using --without-threads I had several .pthread* symbols missing.
I do not have to have threading on this build, but it would be helpful
if it is possible. The machine has the IBM C compiler. Can anyone
suggest a configuration or some change that I can make to cause this to
build correctly? Thanks.

Stop.

Perhaps you need to add -lpthread to the link line. This should be
able to work. What is the link line output from make?

I think that problem has been fixed. Try downloading this file and
replace the one in your build directory:


http://svn.python.org/projects/python/branches/release24-maint/Python/pystate.c

Thanks for your help. I think it worked better after I read the
Misc/AIX-NOTES document. Apparently one -must- use --with-threads.

I grabbed a bzlib.h from the net and created ./Modules/bzlib.h since I
do not have root access. I had to change bz2module.c #include to use
quotes rather than <> symbols so that it would find the header file.

Another problem with building _codecs_cn.c I will put in another
subject. Thanks.
