I wasn't aware that I must prepend *lib* to the library name. Just renaming my link to something.so into libsomething.so did the trick!

[Lazarus] /usr/bin/ld: cannot find -lwhatever
Hi, I'm need to link some C modules to a Lazarus app. I started with just a minimal console app, and one module, I've created with h2pas the binding module, and edited to make it compile properly, but when it comes to link I get the "cannot find" error. I tried both a mymodule.o object and a mymodule.so shared object. I tried putting the .o/.so in the source directory, in the unit directory, and in /usr/lib64 directory (with an ldconfig to update ld cache). I tried declaring the external library just with the module name, and with the full path. I tried adding the path where the .o/.so file is located in the -Fl path of the Compiler Options. The result is always the same: cannot find -lwhatever, with "whatever" reflecting exactly my external library path/name. I'm at loss. What I'm missing?
