Error building on OS X

Error building on OS X

[Timur Tabi]

I'm trying to build a PowerPC-targeted gcc (4.3.3) on a PowerPC OS X
10.5 system.  I have the latest Xcode installed, which comes with gcc
4.0 and 4.2.  The reason I'm doing this is because I want to build a
4.3-based toolchain that can generate Linux binaries for PowerPC
embedded systems.

Unfortunately, I'm not getting very far at all.  When I run this command:

../gcc-4.3.3/configure --target=powerpc-linux --program-prefix=powerpc-

I get this error:

checking for C compiler default output file name... configure: error:
C compiler cannot create executables

and config.log says this:

Producing GCC binaries requires a working C toolchain (C compiler, C
library, assembler, linker,...) for the "host" system, in your case
for OS X 10.5!  The GCC "sources" are mostly in 'C' language, so a
working C compiler for the host is required to compile them. In order
to make the executables for the "OS X to Linux/PPC" crosscompiler,
producing executables for OS X 10.5 MUST work !

The error tells that now you cannot produce any executables for OS X
10.5 with the installed "Xcode" (what on earth is that?) !

This says "powerpc-apple-darwin9"... Is that really the same thing
as "a PowerPC OS X 10.5 system" ?  Ie do you really have GCC etc
made for OS X 10.5 ? Not one made for OS X 9.x ?

Hi Kai,

Xcode is the mac IDE, but if Xcode is there, then gcc also should be
(and on my 10.5.6 intel system it is, and works, to produce binaries).

Timur --- do you have multiple copies of Xcode?  I think sometimes
an earlier version lying around (from an earlier version of the os)
can confuse things (although this may be a red herring).  That
has happened to me, but not on a build of gcc [which i haven't
attempted on a mac in a long time].

I think Kai's keen observation about maybe straying into OS 9
land may be right on point, though [but i don't know how the
darwin numbers correspond to the OS X numbers, so maybe
darwin9 is what you expect, but it sounds funny].

That was my problem.  I thought I deleted the older version of Xcode,
but apparently not.  After carefully following the uninstall
instructions, and reinstalling, OS X's gcc works now.

I then had to download gmp and mfpr, and now I'm building gcc and
binutils.  Thanks, everyone!
