i+## &mdash; 16 August, 2015	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+I've recently been playing around with [PCC](http://pcc.ludd.ltu.se/) and	Err	z3bra.org	70
i+[musl](http://www.musl-libc.org/), and to make the process of compiling	Err	z3bra.org	70
i+softwares with them easier, I decided to setup a cross-compiler relying on both.	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+**TL;DR**: here is the full script. It will create your toolchain in `$HOME/cross/pcc-x86_64` and name the tools `x86_64-linux-musl-*`.	Err	z3bra.org	70

i+2. install linux headers	Err	z3bra.org	70
i+3. build binutils	Err	z3bra.org	70
i+4. build musl	Err	z3bra.org	70
i+5. build pcc/pcc-libs	Err	z3bra.org	70
i+6. (optionnal) add a pkg-config wrapper	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+### 1. grabbing sources	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+This part is pretty simple. You just need to choose which version of the	Err	z3bra.org	70
i+software you want to use. Here is my list at the time of writing:	Err	z3bra.org	70
i+	Err	z3bra.org	70
i++ pcc : 1.1.0	Err	z3bra.org	70
i++ binutils : 2.25	Err	z3bra.org	70
i++ musl : 1.1.10	Err	z3bra.org	70
i++ kernel : 4.1.4	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+You can get the sources by following these links:	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+ftp://pcc.ludd.ltu.se/pub/pcc-releases	Err	z3bra.org	70
i+ftp://ftp.gnu.org/gnu	Err	z3bra.org	70
i+http://www.musl-libc.org/releases	Err	z3bra.org	70
i+https://www.kernel.org/pub/linux/kernel/v4.x	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+Once you have all your tarballs, extract them somewhere.	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+### 2. patch everything	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+Everything doesn't need patching, but when you're playing with musl, you'll	Err	z3bra.org	70
i+quickly realise how heavily softwares rely on the GNU libc.	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+GregorR did all the dirty job here, and provide	Err	z3bra.org	70
i+[patches](https://github.com/GregorR/musl-cross/tree/master/patches) for use	Err	z3bra.org	70
i+with cross-compilers to work with musl. Check what's in, and grab those you	Err	z3bra.org	70
i+might need.	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+The 1.1.0 version of pcc require some patching too, in order to work flawlessly	Err	z3bra.org	70
i+with an alternative libc. It *seems* to be fixed in 1.2.0 (DEVEL version), if	Err	z3bra.org	70
i+you're interrested. They fix the `configure` script to accept musl based	Err	z3bra.org	70
i+targets, and fix the default library pass of the compiler.	Err	z3bra.org	70

i+	Err	z3bra.org	70
i+For this part, just check the appropriate sections in the original script. You	Err	z3bra.org	70
i+might want to enable shared libraries, or avoid compiling everything statically,	Err	z3bra.org	70
i+so tweak it however you want.	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+For PCC, the `PCCINCDIR` and `PCCLIBDIR` are important, as they will tell the	Err	z3bra.org	70
i+compiler where are the PCC libraries. The `--with-incdir` and `--with-libdir`	Err	z3bra.org	70
i+parameters are used to tell the compiler where to search for default libraries,	Err	z3bra.org	70
i+so make sure you set them properly.	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+### Enjoy!	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+You compiler should be ready to go! You can test it by running the following	Err	z3bra.org	70
i+snippet:	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+        $ echo 'main(){}' > dummy.c	Err	z3bra.org	70
i+        $ PATH="$HOME/cross/pcc-x86_64/bin:$PATH"; export PATH	Err	z3bra.org	70
i+        $ x86_64-linux-musl-pcc dummy.c	Err	z3bra.org	70
i+	Err	z3bra.org	70
i+For the sake of the experience, I also built a gcc cross-compiler using the same	Err	z3bra.org	70
i+method, and tested both compilers on the [libressl](http://www.libressl.org)	Err	z3bra.org	70
i+code base. The packages are simply tar.bz2 archives of libressl installed on a	Err	z3bra.org	70
i+chroot (so there are only the libressl files):	Err	z3bra.org	70
