Hi All, I am writing pascal wrapper for a C library called "CTP", which is used in future trading. My project is here: https://github.com/xrfang/CTPas Compiling the interface file along is successful. While linking, fpc complains: ./thostmduserapi.so, needed by ./libthost.so, not found (try using -rpath or -rpath-link) while libthost.so is my wrapper writting in C, which uses thostmduserapi.so, provided by the vendor (no source code).
where is thostmduserapi.so ? Michael.
