A problem about gprof

A problem about gprof

[ZhouY.external]

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


PS. The following is the error messge:

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.

There is no crt0.something in Linux.  Seems your compiler is configured
for some obscure target.  Rebuild your compiler for mips-linux or
mipsel-linux as target.  Zero chance otherwise.
