If your library depends on symbols defined in your program (such as callback functions, etc.), then you need to link your executable so that it exports its symbols. If you're using GNU binutils, you can do this by adding the following command line parameter to your command line for linking your executable: -Wl,-E For example: gcc -Wl,-E -o myprogram <etc., etc.> Thanks, Lyle -----Original Message----- From: gcc-help-owner@xxxxxxxxxxx [mailto:gcc-help-owner@xxxxxxxxxxx] On Behalf Of Thomas.Rogowski@xxxxxxxxxxx Sent: Monday, November 29, 2004 1:49 PM To: gcc-help@xxxxxxxxxxx Subject: access from a dynamic library to the main-program Hello! I have a c++ program and a library separated in an executable and in a library file, the program loads the library dynamicaly and this library must have a pointer to my program. How can I link and compile my library and my program? I use linux. I tried to link program with library and library with program but after that I had two separated files and the library can't access to the instance of my program. Thank you in advance Thomas
