| # 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. |
