I'm using Ubuntu 14.04 on a 32-bit pc. I just compiled gcc 4.9.3 and binutils 2.25, per OSDev instructions. I have tried to compile a cross compiler but I am getting an error I can't resolve:

configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.

I read everything I could find about this error which mostly are written by people trying to build a cross compiler. The articles go back several years with different comments and suggestions on how to fix the problem. I've tried several of the recomendations such as editing lines in files 'libstdc++v3/acinclude.m4' and 'configure.ac', or adding other options after the 'configure' command.

Per OSDev I am using the command
../gcc-4.9.3/configure --target=$TARGET --prefix="$PREFIX" --disable-nls --enable-languages=c,c++ --without-headers.

Does anyone here know how to resolve the error? I'can't go any further and I've run out of clues.

TIA. Bill S.

What is your target triplet?

I'm not sure what 'target triplet' means. i686, ELF format. I will be developing for 32-bit pc. I am running Ubuntu 14.04.

What have you set the environment variable $TARGET to? What about $PREFIX?

export PREFIX="$HOME/cross"
export TARGET=i686-elf
export PATH="$PREFIX/bin:$PATH"

I'm assuming you just typed "make" instead of "make all-gcc" followed by "make all-target-libgcc".

Just typing "make" tries to build libstdc++ as well, which can't be done in a freestanding configuration. Please read the instructions here.

I was doing:
make,
make all-gcc,
make all-target-libgcc.

Wrong. Thanks for your help.
