A problem about gprof
Often there are seperate precompiled versions of libraries that where compiled with profiling on. For example, if you have glibc-profile installed you should change your -l into a -l_p. Just a hunch, but check to see if you have a profiled version of the "e" library.

Hi dear experts,
In order to use the gprof in the SDE 5.02 toolchain, I compiled a program
with '-p' option but the compiler responsed with a error. I have checked the startup assembly code crt0.sx. There is an address operation which need the address of '_ecode'. Which library has the symbol '_ecode'? Could you give me a clue?
Thanks in advance!Best regards,
Yidan
