Well, after no response at all, trying to compile V1.9.14 via Code:Blocks &mingw-sjlj, hanging here: error: 'ADDON-DIR' was not declared in this scope . #ifdef WIN32 void BuildClientPath(char* path_to_so, int path_len, const char* so_name) { snprintf(path_to_so, path_len, ADDON_DIR "/%s.dll", so_name); } What now?
