23 years ago Martin v. Loewis asked me to report that dynamic loading fails on Mac OS X. I was able to successfully build the CVS version of Python following the directions posted by Dan Wolfe to Python-Dev:
http://www.python.org/pipermail/python-dev/2000-September/016289.html
However, I had some problems compiling the CVS version of Python/XML and reported them as a bug to Source Forge:
https://sourceforge.net/bugs/?func=detailbug&group_id=6473&bug_id=115544
Martin pointed out "how distutils comes up with the linker line: They read the configure-generated Makefile and scan for LDSHARED. So anything that was in the Python Makefile will be used when linking a distutils module." He aksed me to try to build Python a few different ways, but they all failed.
When configured with:
./configure -with-threads -with-dyld --with-next-framework -with-suffix=.exe
Building Python produced the following:
cd Modules ; make OPT="-g -O2 -fno-common" VERSION="2.0" \
prefix="/usr/local" execprefix="/usr/local" all
make[2]: Nothing to be done for `all'.
libtool -o libpython2.0.dylib -dynamic libpython2.0.a -framework System
ld: for architecture ppc
ld: Undefined symbols:
restFP
saveFP
_\_eprintf
_environ
libtool: internal link edit command failed
make[1]: [libpython2.0.dylib] Error 1
make: [python.exe] Error 2
When line 579 in "configure" is modified to the following:
then LDSHARED='$(CC) $(LDFLAGS) -bundle -undefined suppress'
building Python results in the following:
for i in Parser Grammar Objects Python Modules; do \
(cd $i; make VERSION="2.0" add2lib); done
make[2]: add2lib' is up to date. make[2]: Nothing to be done foradd2lib'.
make[2]: add2lib' is up to date. make[2]:add2lib' is up to date.
make[2]: `add2lib' is up to date.
libtool -o libpython2.0.dylib -dynamic libpython2.0.a -framework System

libtool: internal link edit command failed

I have only been using Mac OS X for a few days (and the development tools even less), so this could definitely be due to user error, but I will help out however I can.
