Creating Library files?

Well,

It depends if you want to make shared libraries or static libraries.

The general procedure to do, say for C and assuming GNU tools, for a shared library is:

user@machine:~ $ gcc -c -fpic module1.c module2.c module3.c
user@machine:~ $ ld -Bshareable -o mylib.so.1.0 module1.o module2.o module3.o


Then obviously you''ll have to link against this library to use it when you compile programs that use those library calls.


FYI HTH,

.zfod

Also,

Remember to do the ldconfig stuff if you''re using such a system to create the necessary links and cache. Also, if you''re using a non-standard trusted lib directory you can add it. If not, be sure to set your LD_LIBRARY_PATH accordingly.

Static. I wan''t the stuff compiled directly into my programs.

Thanks for the info on the shared lib''s though I might be makeing one of those eventually too.

Ahh,

Ok, just do the following with your object code:

user@machine:~ $ ar rc mylib.a module1.o module2.o module3.o
user@machine:~ $ ranlib mylib.a

This creates the static library mylib.a that you can link against.

Tried that. It dosn''t want to work right. I have to have a global instance of each class object in the library or the I get undefined referance errors on all the class function calls in my project.
