Im asking this question here as I just can't seem to find the answers elsewhere or they are buried so deep in C/C++ related issues I just simply can't sift through them ...

Im writing a a library in assembly using Gnu AS on linux.
Im having a little trouble makeing an .so and also, linking to that .so from
another program (also assembler).

Would some have and example or point me to one that is rather simple?
Even if its just a hello world function in a .so being called from another
prog ?

rgs, James.

Sorry for the long wait... here is an example of shared object and two ways of using it.

The library will be installed into /usr/lib but you can change it from the makefile.

2 pelaillo:
Your SO isn't position-independent (PIC compliant). That's not good.

The post is old, but i think that next example will be useful for someone.
