I have configured as follows: configure --enable-languages=c,c++ --target=arm-elf --with-gnu-as --with-gnu-ld --prefix=path-to/arm-elf-gcc-4.5.0
The given $prefix should be some 'absolute' pathname, the default is '/usr/local' when no '--prefix=$prefix' is given. Yours is 'relative' to some directory.
when I make all I get the following error: Links are now set up to build a cross-compiler from x86_64-unknown-linux-gnu to arm-unknown-elf. checking for exported symbols... path-to/arm-elf-gcc-4.5.0/arm-elf/bin/objdump: conftest: File format not recognized checking for -rdynamic... path-to/arm-elf-gcc-4.5.0/arm-elf/bin/objdump: conftest: File format not recognized
Hard to say what is the search root for these, probably the main $BUILD directory. In any case there seems to be nothing which the configure script expects, here an 'objdump' for the 'arm-elf' target...
my system is ubuntu 9.10 64 bit with gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu9) binutils: GNU ld (GNU Binutils for Ubuntu) 2.20
Of course you should first have binutils for 'arm-elf' in the '$prefix/bin' (for humans and this dir in PATH) and in '$prefix/arm-elf/bin' (for the GCC to be built). The 'path-to/arm-elf-gcc-4.5.0/arm-elf/bin/objdump' shows this scheme with your given $prefix and $target values.
