# Shell script to build the Python shared library properly; if we haven't
# already built the export list, we'll need to link twice (argh...) so we
# can eliminate some unwatnted global symbols from the system glue/init
# objects.
#
# This is called by the Modules/Makefile as part of $(LINKCC):
#
# $(LINKCC) $(LDFLAGS) $(LINKFORSHARED) $(MAINOBJ) \
#	-L.. -lpython$(VERSION) $(MODLIBS) $(LIBS) $(SYSLIBS) -o python $(LDLAST)
#
# In 1.5.1 this changed to:
#
# $(LINKCC) $(LDFLAGS) $(LINKFORSHARED) $(MAINOBJ) \
#	$(LIBRARY) $(MODLIBS) $(LIBS) $(SYSLIBS) -o python $(LDLAST)
#
# For BeOS we should set $(LINKCC) to this in configure (similar to the
# AIX situation):
#
# $(srcdir)../BeOS/linkcc $(LIBRARY) $(PURIFY) $(CC) $(OPT)
#
# -L.. -lpython$(VERSION) will automagically pick up the shared library.
#
# As of Python 1.5.2, this isn't strictly necessary, but it makes me
# feel safer.  It makes sure we've got all the BeOS-specific libraries,
# and it creates the "lib" symlink that we'll need for chance of running
# "make test" successfully.
