Does anyone have any experience attempting this? I'm not asking for support for Zope on AIX, just for support for the build system. ;-) Building from the source distribution, having built my own Python 1.5.1 separately, mis-sets the "srcdir" variable to ".", from the perspective of a linking script found in $PYTHONHOME/lib/python-1.5/config. This makes the .o files not get linked into shared libraries. Alas, hard-coding paths didn't get me a success. So I tried the binary porting kit, and it was worse. It made its own python, then installed it as local/bin/python-1.5 and later tried to invoke it as local/bin/python. I never did get it to work, as there were numerous problems at the "can't build Makefile" level, and several core dumps from /bin/sh(!). One problem that there's little excuse for, when building from your standard source distro: Compiling extensions in lib/python make -f Makefile.pre.in boot PYTHON=/home/kwr/bin/python [...snip...] gcc -g -O2 -I/home/kwr/include/python1.5 -I/home/kwr/include/python1.5 -DHAVE_CONFIG_H -I../Components/ExtensionClass -c ./../Components/ExtensionClass/ExtensionClass.c ./ld_so_aix gcc ExtensionClass.o -o ExtensionClass.so make: ./ld_so_aix: Command not found make: *** [ExtensionClass.so] Error 127 make clean rm -f *.o *~ (1) Hey! You failed to make the shared object! Stop! (2) Hey!!! You failed!!! Don't clean up the evidence!!! (3) ld_so_aix is in the $PYTHON_HOME/lib/python1.5/config directory; the "." in "./ld_so_aix" comes from $(srcdir). Dunno who's wrong here. Keith (at least Python seemed to build OK)
