Using .so files

If I have a file libx.so, and want to use it's method xyz(void).
Have to a in C with GCC use that method, assuming that I know all this at compilation (not runtime linking)?

Yes, but I can only find how to create .so files.

Re: Using .so files

I am not entirely sure that I understand what you need but you can either install it in /usr/lib or if you just want to use it locally adjust the LD_LIBRARY_PATH so that it includes the directory at which your library is located. Also when compiling don't forget to add the -L flag to gcc followed by the directory where the shared library is located. Also you might need to add the -I flag (that's a capital i) as well followed by the path where the header(s) of your library is(are) located. Some more information plus some examples here and here.

Seems about right, but I do not need to do it anymore.

Thanks anyway!

Re: Using .so files

One both of your replays:

??

And on 'tomk':
I assume you mean, that you think I passed a homework.
No, this has nothing to the with homework, than I would just ask my teacher(s) [look at the time 04:23:56 UTC+2, they are clearly working and can answer me right away].
No, this was a part of hacking Java with modifying it's files, but there was an easier way to do what I wanted to do (without hacking Java).
