c program / repertory

hello,

I was wondering where I have to copy the different c librairies and c
functions in QNX.

if I copy them in the bin repertory, does I only need to do a:
#include<math.h> a the beginning of the program?

thanks.

You don’t need to copy them anywhere the compiler front end (cc or qcc )
knows where to look for them.

#include <math.h> is fine, but you may have to use -lm to tell
the compiler to link with the math library.

thanks.

I agree for the librairy included in the compiler. but what about the
librairy that I created?
I have several librairy for my I/O boards but I don’t know in which
repertory to copy them.

thanks

I would used the -L option to tell the linker where to look for library,
and then specify -l for each of your library.

thanks
