hi
actually i am new to linux gcc programming.
i have created a c file which contains code to send input to a serial communication device. i converted it into a shared object file so that my client will be able to use the library in his program, the test program which i used in the development system with the library file installed in the /usr/local/lib works well. so i decided to send the xxx.so.0.0 file to the client and asked him to put in the same /usr/local/lib folder and give an ldconfig -n. to update the library files. he did that exactly and created a test program to use the library file in the desktop, but while compiling an undefined function `function name` error returns in main. i actually dont want to distribute the source. so my question is how to distribute the library file to a client system with out asking him to compile my source.

thanks in advance for your kind time.

best regards
s.an

You need to provide to your users an include file (.h) that contains the function prototypes for the exposed functions in your .so
