configure: error: C compiler cannot create executables

I have just tried to compile MRTG-2 from source and have received this message configure: error: C compiler cannot create executables.

Code: 
krishna:~/Desktop/mrtg-2.14.7 $ ./configure --prefix=/usr/local/mrtg-2
checking for gcc... gcc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.

Naturally, we do what we're asked, but it's at the end.

Code: 
krishna:~/Desktop/mrtg-2.14.7 $ gcc -v
Using built-in specs.
Target: powerpc-apple-darwin8
Configured with: /private/var/tmp/gcc/gcc-5250.obj~12/src/configure --disable-checking -enable-werror --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^.-]*$/s/$/-4.0/ --with-gxx-include-dir=/include/c++/4.0.0 --build=powerpc-apple-darwin8 --host=powerpc-apple-darwin8 --target=powerpc-apple-darwin8
Thread model: posix
gcc version 4.0.1 (Apple Computer, Inc. build 5250)

I've got XCodeCore 660.0 (aka XCode Tools 2.2.1) installed on 10.4.7 with all updates, as well as Fink 0.23.10.

Here's config.log; any help is appreciated because this has happened with another application as well (but I assumed it was the program itself that was broken--it looked like it was trying to create an EXE).

Code: 
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.59.  Invocation command line was

  $ ./configure --prefix=/usr/local/mrtg-2

configure: exit 77

:)
 
I'd suggest moving your Fink installation out of the way temporarily to see if that's causing a problem. Just do:

mv /sw /sw.SAVE

and then try your 'configure' command again, and post back here what you get.
 
Here is the reason your configure script failed:

Code: 
configure:1657: checking for C compiler default output file name 
configure:1660: gcc conftest.c >&5 
/usr/bin/ld: can't locate file for: -lcrt1.o 
collect2: ld returned 1 exit status
The problem is crt1.o can't be located so gcc can't link programs that will actually run. On my Linux system, crt1.o is in /usr/lib. I don't know where it will be on OS X.

Good luck!

Peace...
 
crt1.o is in /usr/lib on OS X, too.

I don't think this is necessarily causing the error, but the configure script appears to be using
gcc -V
to get the version of gcc. At least on OS X, this has to be
gcc -v
The former is used not to establish the version, but to specify a version if, say, there are multiple versions of gcc installed this can override the default.

I would be suspicious of the "-lcrt.o" since crt.o is not a library, is it? I'm not sure how this works, though. Normally for library X, say, you'd have X.dylib in /usr/lib or wherever, and you'd pass "-lX". I'm not sure, but OS X is very fussy about libraries - increasingly so, unfortunately.

You could also poke around in the conftest.c to try to figure it out. If other OS X users have the same problem, you might try searching the applications mailing list archives or bug reports or, failing that, post one yourself.

One question would be: can you compile some applications OK or are you having problems with all compilations? If the latter, it obviously isn't a bug in the application but presumably some quirk in your setup. I'm guessing the former, though, but I'm not sure.
