Hello,

I guess this is a very basic question but how do you make FASM output .so shared objects? And how can you import functions from other shared objects? Thank you,

Use format ELF with at least one executable section and export the symbols by means of public directive.

To import any symbol, load the shared object with dlopen and then use dlsym to obtain the pointer to the symbol required. For most system libraries, symbols are already resolved by the loader.

Im new here and I registered as I wanted to do linux assembly and specifically .SO's

Do you have an example of a basic .SO that could be built with FASM ?
