ewxb - Erik Westrup's GCC cross-compiler builder

This is a script documenting the steps and phases take when I compiled a GCC cross toolchain for GCC 4.9 head (with Go support). Building a cross-compiler is complex due to dependencies so a lot of bootstrapping has to be done. This script is inspired by Jim Blandy's excellent eglibc cross-compiling guide posted at eglibc's mailinglist at [patches] Cross-building instructions.

This script can serve as a starting point for those who want to build a x-toolchain from scratch. Don't expect it to work in directly as it's tailored for my setup. Instead you can re-use the phases and modify the script with parameters that you need. The last phases adds Go support, which is easy to comment out if you're only interested in a C/C++ compiler.

My setup was:

Host/Build system: Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux
Target: mips
gcc: 4.9.0
glibc: 2.19
binutils: 2.24

The scripts makes it easy to run specific phases (or range of phases) so that you easly can tweak a failing phase and continue with the ones that follows when you have got one phase to work. Make sure to edit x_environment.sh to the right versions of the packages and build paths to use.

For any details, simply read the sauce.

More info about using Go with a gccgo cross-compiler can be found at the go-wiki.

The sweet result after playing some Rube Goldberg trickery games.

Error in script

I've found a small error in the ewxb-script:

line 217:
$sysroot
ist wrong and empty.
Replace it with
$SYSROOT (capital letters).

Cannot build a version of go tools aware of gccgo powerpc

Hi,

I have followed the steps necessary to build GCCGO for PPC (32 bits) here with the help of this script as well.

I cannot manage to finish the last step (Build a cross-gccgo aware version of the Go tool),
I cloned the go source code (with git, then checked out go1.12.1) in /tmp

I am trying to make:

> $HOME/gogit/bin/go build -o xgo -compiler gccgo -x .

work inside src/cmd/go. Go is apparently trying to fetch crypto, arch, tool and sys packages and I am getting this error:

    WORK=/tmp/go-build326274842

Problem in finishing Phase 7

I am trying to build the tool chain to compile GO 1.3.3 on x86_64 with target set to x86_64 and I am running into issues with step 7. Following is the error message.

/root/src/x86_64-unknown-linux-gnu_gcc_build/tools/x86_64-unknown-linux-gnu/lib/../lib64/libstdc++.so.6.0.21-gdb.py is not an ELF file

Things I changed are
+export TARGET="x86_64-unknown-linux-gnu"
+export LINUX_ARCH="x86_64"

+#export GCCV=gcc-4.9.0
+export GCCV=gccgo

-export LINUXV=linux-2.6.31.14 (MAY BE NOT NEEDED)
+export LINUXV=linux-3.13
