CodeLite can't fin include files - <math.h>

Loaded CodeLite on my Ubuntu machine, tried to build c-code and it could not find the include file <math.h>. Seemed to be ok with the include statement but could find the functions sqrt() and pow(). I know that the proper files are on my machne becaue Code::Blocks functions properly, and so does NetBeans IDE.

You should post the build information + your codelite version

CodeLite 5.4 (so now I will get an answer, doubtful)

To build a C-file using math.h, the GNU people say you have to link it. For a compile and link with the executable name same as file
in a terminal session you would enter:

gcc c_file.c -o c_file -lm

The -lm links the math lib. I had this same issue with Geany, however there is an option to set compiler options, i.e the -lm. Have not been able to
determine how to do this in codelite. This is the question to be answered.


For those who like the details:

/bin/sh -c 'make -j 2 -e -f Makefile'

No need to respond ....
I resolved the issue myself.
Hope you guys enjoy reading all that build-log data.
