where is the lib of "cexp" about GCC?

I had wrote a program and gcc -c XXX.c, the error is undefined
reference to 'cexp' , I want to link the lib about 'cexp', but I don't
know where it is.

This is an FAQ - <http://www.c-faq.com/>

Basically you need to include an '-lm' switch with your compilation
command:

gcc -c xxx.c -lm

This tells the linker to link against the system's math libraries which
are separate from the Standard C library on UNIX systems.

Add -lm.
