Dear users, This is a reposting of Fei Wang's question from a few days ago concerning builds on MAC OSX 10.3.*. I have the same problem, but I fear I am being stupid. I have downloaded gcc3.3 and gcc3.1 sources, and when I try to build either I get the same error as I try to configure: *** The command 'cc -o conftest -g conftest.c' failed. *** You must set the environment variable CC to a working compiler. It seems as if I need a c compiler to begin with. I don't know what to do. I read in the html documents that cc must be set or else failure will happen during configuring. Well it happens. What am I to do? I have installed the prepackaged gcc3.1 compilers that come with the MAC operating system; however, they do not have g77 bundled in there so I uninstalled those binaries and tried to build from scratch. Any help would be great.
