My problem is lack of familiarity with the ./config command producing error with gthread cflags or will not run libobjc ./configure. The & has nothing to do with the configure script, it tells the shell to run the process in the background, e.g. sleep 5 & echo blah this will run a "sleep 5" process in the background and immediately run "echo blah" as a separate command so you command is running "configure" in the background ,then trying to run the other options as a separate command, which is totally wrong. Try reading the docs that come with the sources, gcc-3.4.5/INSTALL/index.html, that will tell you how to run configure. Or just run ./configure --help
