Cross Compile to make a Native Compiler

["Daniel Laird" <danieljlaird at hotmail dot com>]

Hello everyone.

I am trying to make a native mips-linux compiler.  I have a cross compiler 
which runs on intel-linux so i thought i could try to cross compile the 
cross compiler to make a native compiler.  Has anyone done this?

I can configure using the following line
../combined-src/configure --target=mipsel-linux --host=mipsel-linux 
--prefix=/export/home/laird/phoenix_toolchain/native/mips-tools-
3.0.2/ --enable-languages=c,c++ --with-gnu-as --with-gnu-ld -v

this builds the links for a native mips compiler.

I also have to set environmental variables as follows
export CC_FOR_BUILD="gcc"
export CXX_FOR_BUILD="gcc"
export CC="mipsel-linux-gcc"
export 
CC_FOR_TARGET="/export/home/laird/phoenix_toolchain/cross/combined-build/gcc/xgcc 
-B/export/home/laird/phoenix_toolchain/cros
s/combined-build/gcc/ -isystem 
/export/home/laird/phoenix_toolchain/native/mips-tools-3.0.2/mipsel-linux/sys-include"
export GCC_FOR_TARGET="$CC_FOR_TARGET"
export CC_FOR_TARGET="$CC_FOR_TARGET"
export CXX_FOR_TARGET="$CC_FOR_TARGET"
export AS_FOR_TARGET="mipsel-linux-as"
export LD_FOR_TARGET="mipsel-linux-ld"
export NM_FOR_TARGET="mipsel-linux-nm"
export AR_FOR_TARGET="mipsel-linux-ar"
export RANLIB_FOR_TARGET="mipsel-linux-ranlib"
export 
PATH=/export/home/laird/phoenix_toolchain/cross/mips-tools-3.0.2/bin:$PATH
CC=mipsel-linux-gcc

This looks like ti could work but when generating gencodes it builds for the 
wrong architecture(mips execuatble) If i hack the makefile to solve this 
problem later on it wants files to be mips so that it can link them.

Has anyone ever managed to make a native compiler using a cross compiler?  
how did you do it?

Any help much appreciated.
Cheers
Dan

p.s I have tried the website http://www.objsw.com/CrossGCC/FAQ-4.html#ss4.9 
and it helps but does not work.
