   9 # Shell script to build the Python shared library properly; if we haven't
  10 # already built the export list, we'll need to link twice (argh...) so we
  11 # can eliminate some unwatnted global symbols from the system glue/init
  12 # objects.
  13 #
  14 # This is called by the Modules/Makefile as part of $(LINKCC):
  15 #
  16 # $(LINKCC) $(LDFLAGS) $(LINKFORSHARED) $(MAINOBJ) \
  17 #       -L.. -lpython$(VERSION) $(MODLIBS) $(LIBS) $(SYSLIBS) -o python $(LDLAST)
  18 #
  19 # In 1.5.1 this changed to:
  20 #
  21 # $(LINKCC) $(LDFLAGS) $(LINKFORSHARED) $(MAINOBJ) \
  22 #       $(LIBRARY) $(MODLIBS) $(LIBS) $(SYSLIBS) -o python $(LDLAST)
  23 #
  24 # For BeOS we should set $(LINKCC) to this in configure (similar to the
  25 # AIX situation):
  26 #
  27 # $(srcdir)../BeOS/linkcc $(LIBRARY) $(PURIFY) $(CC) $(OPT)
  28 #
  29 # -L.. -lpython$(VERSION) will automagically pick up the shared library.
  30 #
  31 # As of Python 1.5.2, this isn't strictly necessary, but it makes me
  32 # feel safer.  It makes sure we've got all the BeOS-specific libraries,
  33 # and it creates the "lib" symlink that we'll need for chance of running
  34 # "make test" successfully.
