I tried to make a new linux release on my RedHat 7.1 box.

First I configured, compiled and installed binutils:
./configure --target=avr --exec-prefix=/opt/avrgcc --prefix=/opt/avrgcc
make install
-> everything OK

Appended /opt/avrgcc/bin to the PATH

Then I configured gcc with:
 ./configure --target=avr --exec-prefix=/opt/avrgcc --prefix=/opt/avrgcc
--disable-nls --enable-language=c

After compiling a lot of stuff I get this error:

checking whether the C compiler (/tmp/gcc-3.0.1/gcc/xgcc
-B/tmp/gcc-3.0.1/gcc/ -B/opt/avrgcc/avr/bin/ -B/opt/avrgcc/avr/lib/
-isystem /opt/avrgcc/avr/include -g -O2 ) works... no
configure: error: installation or configuration problem: C compiler
cannot create executables.
make: *** [configure-target-libiberty] Fehler 1

I have seen the same problems, I have not figured out what is causing it, but doing a 'make' (which gives the error) then a 'make install' seems to work out ok.

Its something to do with missing library header files.

You need the newlib header files to build the libraries that build with the compiler.
