Installing shared library

[Harichand M V]

I want to install a shared library.
I created a .h file and .c file and
compiled it as follows
cc -c *.c
gcc -shared -o libsim.so *.o

I copied the libsim.so file to /usr/lib and the .h file to /usr/include. But problem is that I cant access library. I included the .h file in my program. Still not working.Please help!!

Did you use the "-lsim" option when compiling your program?

What was the error message?

Did it appear when trying to compile your program? Or was the compilation successful but the program displays an error message when you try to run it?

(The correct "-l" option is formed by taking the library name, leaving out the suffix .a, .so or .sl and replacing the "lib" in the beginning with "-l". Thus, libsim.so -> -lsim)

Note that the suffix of the shared library should be .sl instead of .so in PA-RISC-based HP-UX. With Itanium-based versions, .so is the recommended suffix but .sl may be used for backwards compatibility reasons.
