gcc on MAC OSX

gcc on MAC OSX

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.

Cheers,
Michael Grabe

Hi Michael,

 >It seems as if I need a c compiler to begin with.

Correct.  That is true for all platforms that GCC is used upon.

 >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.

Build from scratch first, THEN uninstall those binaries.

HTH,
