By the way, why son't you just add your `/lib/x86_64-linux-gnu/` directory to the library path? I believe there was an command line option for fpc that did that (or you can maybe pass a similar option to the linker directly). [not tested: try adding `-Fl/lib/x86_64-linux-gnu/` to the fpc command line?]

IIRC the part after `.so` is considered a version number (or indication thereof). The behaviour you are seeing is *probably* that the linker could not find `libcrypto.so.1.2.asdasd`, so it decides to use the one it found instead. Anyway, I don't know that much about `the linker` either, but this would be my guess. -- Ewald _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
