Many people have expressed interest in getting g++ to support the -p and -pg profiling options. Until the 1.36 release the profiling situation looked grim... However, it appears now that there is at least some support for profiling with g++ on machines that use GNU gas and GNU ld. To get it working simply apply this patch: *** cplus-decl.c.~1~ Wed Oct 11 07:37:53 1989 --- cplus-decl.c Wed Oct 11 21:30:42 1989 *************** *** 2444,2451 **** current_binding_level = NULL_BINDING_LEVEL; free_binding_level = NULL_BINDING_LEVEL; ! if (profile_flag) ! fatal ("profiling not yet supported in GNU C++"); if (profile_block_flag) fatal ("`-a' profiling not yet supported in GNU C++"); if (write_symbols == GDB_DEBUG) --- 2444,2451 ---- current_binding_level = NULL_BINDING_LEVEL; free_binding_level = NULL_BINDING_LEVEL; ! /* if (profile_flag) ! fatal ("profiling not yet supported in GNU C++"); */ if (profile_block_flag) fatal ("`-a' profiling not yet supported in GNU C++"); if (write_symbols == GDB_DEBUG) Remember that g++ mangles names; it may take a little while to get familiar with the output from prof or gprof! I'm sure if I've forgotten anything someone will remind me ;-) Doug -- Master Swordsman speak of humility; | schmidt@ics.uci.edu (ARPA) Philosophers speak of truth; | office: (714) 856-4034 Saints and wisemen speak of the Tao of no doubt; The moon, sun, and sea speaks for itself. -- Hiroshi Hamada
