CT-NG 1.5.2: configure: error: C compiler cannot create executables

CT-NG 1.5.2: configure: error: C compiler cannot create executables

[Alex]

Dear all,

this is my first mail to this list.  I really hope you can help me.  I
am trying to build a toolchain for "powerpc-unknown-linux-uclibc"
under Ubuntu 9.10 with CT-NG 1.5.2 and gcc (Ubuntu 4.4.1-4ubuntu8)
4.4.1.  I am using the .config file from the "samples" directory of
CT-NG.

Unfortunately I get the following error:
[INFO ]  Installing final compiler
[EXTRA]    Configuring final compiler
[EXTRA]    Building final compiler
[ERROR]    checking for C compiler default output file name...
configure: error: C compiler cannot create executables
[ERROR]    make[2]: *** [configure-target-libmudflap] Error 1
[ERROR]    make[1]: *** [all] Error 2
[ERROR]    Build failed in step 'Installing final compiler'
[ERROR]    Error happened in
'/home/alex/ctng/lib/ct-ng-1.5.2/scripts/functions' in function
'CT_DoExecLog' (line unknown, sorry)
[ERROR]          called from
'/home/alex/ctng/lib/ct-ng-1.5.2/scripts/build/cc/gcc.sh' at line #
350 in function 'do_cc'
[ERROR]          called from
'/home/alex/ctng/lib/ct-ng-1.5.2/scripts/crosstool-NG.sh' at line #
544 in function 'main'
[ERROR]    Look at
'/home/alex/x-tools/powerpc-unknown-linux-uclibc/build.log' for more
info on this error.
[ERROR]  (elapsed: 31:58.23)
[31:58] / make: *** [build] Error 2

GCC is working on my system, I have successfully compiled etc. a
"Hello World" program.

Any help would really be appreciated!

Regards,
Alex

Hi Alex!

The "C compiler cannot create executables" error is very common and 
almost always confusing. It is often caused by the configure script 
calling $CC with invalid $CFLAGS, $LDFLAGS, bad $LD_LIBRARY_PATH or similar.

The file /home/alex/x-tools/powerpc-unknown-linux-uclibc/build.log in 
your case probably references a more readable failure in the libmudflap 
build directory. You can see more in 
<somewhere>/targets/powerpc-unknown-linux-uclibc/build/build-cc/powerpc-unknown-linux-uclibc/libmudflap/config.log, 
which likely tells us a bit more about your particular problem.

My guess, however, is that you've run into a problem similar to what I 
had a couple of weeks ago when attempting to build an Arm (big-endian) 
toolchain on my Ubuntu 9.10 (32-bit) system:

     http://sourceware.org/ml/crossgcc/2009-12/msg00039.html

It took a while figuring out the problems, but the latest crosstool-NG 
in the Mercurial repository has a couple of patches against GCC 4.4.x 
and binutils that may help you out. Simply "sudo apt-get install 
mercurial" and then checkout the tree:

     hg clone http://ymorin.is-a-geek.org/hg/crosstool-ng

Please let us know how things turn out for you, good luck!

Regards
  /Joachim
