Ah FC4 installed at all because I want other people to do, the impact on Canton. My system is debian sarge, gcc-3.3, boost-1.32 Cygwin boost-1.31 no problems I think you can try something. Redirection first, you redirect the output of the procedure to a document, whether or not normal output. G++3 then translated version of the compiler that can output. [ Closed window ]
