I, too, am having difficulties building a cross-compiler.
I've followed the article in the wiki to the letter, but when I try to compile binutils, I get these errors:

Code: Select all

I'm building this using Cygwin, on a 32-bit Windows 7 machine.

Permission denied

Have you tried running with administrator privileges?

Yeah, I should've guessed that was the problem. Though I'm curious... I've compiled many things with cygwin before, and I never needed it to be run with admin privileges. Why now?

Thanks anyway.

One of my development machines is now running a 64-bit Windows 8, and of course the previously compiled cross compiler no longer works.
However, re-doing all the steps in the Cross-compiler tutorials doesn't produce a working environment.
Binutils compiles fine, but during the compilation of GCC, I run into the following errors:

Code: Select all

Configuring in ./fixincludes
configure: loading cache ./config.cache
configure: error: `target_alias' has changed since the previous run:
configure:   former value:  `i686-pc-cygwin'
configure:   current value: `i586-elf'
configure: error: in `/usr/src/build-gcc/fixincludes':
configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm ./config.cache' and start over
Makefile:3236: recipe for target `configure-fixincludes' failed
make: *** [configure-fixincludes] Error 1

I have not changed anything between running

Code: Select all

cd /usr/src/build-binutils
../binutils-x.xx/configure --target=$TARGET --prefix=$PREFIX --disable-nls
make all
make install

and the build of GCC, yet, for some reason, it seems as though my target gets changed.

I don't have the answer to that question but I did have the same problem once: Solved problem building cross compiler.

I finally managed to compile GCC. I re-ran cygwin setup, reinstalled the required libs and updated some programs, and that produced a working GCC, but now I get a different error when trying to compile my kernel, namely:

Code: Select all

 /usr/local/cross/bin/i586-elf-ld.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory

This is the exact error that made me recompile my GCC previously. (I had simply copied it over from my 32-bit machine, hoping it would work on 64-bit also)

EDIT: Running GCC from cmd showed that it couldn't find cygwin1.dll
After adding the cygwin bin directory to my PATH the error went away.
