Hi,

maybe you know, just in case not...

You allow use of bespoke python build for the most part.  There is an 
issue in the linking though - I had to make the following change so that 
gdb was linked with my python rather than the system one.  I suppose 
that you should set some sort of PYTHONLIBS variable that contains the 
path to the relevant libs (somewhat like you do for INTERNAL_CPP_FLAGS).

CLIBS = $(SIM) $(READLINE) $(OPCODES) $(BFD) $(INTL) $(LIBIBERTY) $(LIBDECNUMBER) \

         $(XM_CLIBS) $(NAT_CLIBS) $(GDBTKLIBS) -ldl -lncurses -lz -lm    -lpthread -ldl -lutil -lm  -lpython2.7 -Xlinker -export-dynamic \

         $(LIBEXPAT) \

         $(LIBIBERTY) $(WIN32LIBS) $(LIBGNU)

CLIBS = $(SIM) $(READLINE) $(OPCODES) $(BFD) $(INTL) $(LIBIBERTY) $(LIBDECNUMBER) \

         $(XM_CLIBS) $(NAT_CLIBS) $(GDBTKLIBS) -ldl -lncurses -lz -lm    -lpthread -ldl -lutil -lm -L$(MY_PYTHON)/lib -lpython2.7 -Xlinker -export-dynamic \

         $(LIBEXPAT) \

         $(LIBIBERTY) $(WIN32LIBS) $(LIBGNU)



Incidentally, the reason why I was compiling was this:

$ gdb `which python` core.23394
gdb: symbol lookup error: gdb: undefined symbol: 
PyUnicodeUCS4_FromEncodedObject

confusion with unicode...

Regards,

Paul.
