# 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) -nodup $(OPT)
|
|
#
|
|
# -L.. -lpython$(VERSION) will automagically pick up the shared library.
|
|
|
|
# Check to make sure we know what we're doing.
