Hi list,
I'm trying to compile my C application with gprof but it is not working.
This is a multithreaded program that use mysql and openssl libraries.
Reading the man page I see that is need add -pg to the compile command
line, but when a do this the following error occurs at linking time
$ gcc -L/usr/local/lib/mysql -Wall -I. -I.. -I/usr/local/include/mysql -o
serverd ../log.o ../mem.o ../misc.o ../threads_wrapper.o ../openssl.o db.o
main.o request.o ssl_server.o ssl_socket.o threads.o threads_control.o
-pthread -lmysqlclient_r -lssl -pg

*** Error code 1
Stop in /usr/home/ale/personal/ale_projects/works/program/server.
I tried to substitute the -pg compiler flag by -lc_p, with this flag the
program compile but is not linked with libc_p and don't generate the gprof
output file...
$ gcc -L/usr/local/lib/mysql -Wall -I. -I.. -I/usr/local/include/mysql -lc_=

Any ideas ?
