Hi Stulov, > Can compiler use project sources packed in archive? I think the answer depends on your OS. If your OS can mount archives as volumes, then the answer is yes. If your OS cannot mount archives as volumes, then the answer is no. The compiler would be oblivious that the project sources are packed in an archive. If the archive is read-only, you'd be responsible for telling the compiler to put the output in a suitable output target directory. Sincerely, --Eljay
