I tried to do something similar here but it didn't work. Any solutions?

Try again - this below should work. ------- header file -------- namespace xxx { extern int a; extern char foo[]; }; ---------------------------- ------- implementation cpp file ------- #include "header-file" namespace xxx { int a = 2; char foo[] = "ABCD"; }; --------------------------------------- Back to top vsgdp Guest Posted: Sun Sep 28, 2003 7:32 am    Post subject: Re: namespace problem Most excellant.
