# `mussel`
`mussel` is the shortest and fastest script available today to build working cross
compilers that target `musl` libc
## Features
1. **Up-to-date**: uses latest available upstream sources for packages
2. **Fast**: probably the fastest script around to build a cross compiler
targeting `musl` libc, and runs fully under `dash`
3. **Short**: has the least amount of steps ([see
below](#how-is-mussel-doing-it)) required
to build a cross compiler targeting musl libc (even less than
[musl-cross-make](https://github.com/richfelker/musl-cross-make))
4. **Small**: all installation steps use `install-strip` where applicable
5. **Simple**: easy to read, modify and extend
6. **POSIX Compliant**: the entire script is POSIX compliant
7. **Well Documented**: the script comes with a
[`DOCUMENTATION.md`](DOCUMENTATION.md)
file that includes state of the art information explaining what is being done
and why
## Requirements:
To confirm you have all required packages, please execute `./check`
## Usage
### Building a Cross Compiler
```Shell
./mussel (arch) (flags)
```
**(arch)**: See [**Supported
Architectures**](#supported-architectures)
below
**(flags)**:
```Console
f | -f | --enable-fortran Enable optional Fortran support
k | -k | --enable-pkg-config Enable optional pkg-config support
l | -l | --enable-linux-headers Enable optional Linux Headers support
o | -o | --enable-openmp Enable optional OpenMP support
p | -p | --parallel Use all available cores on the host system
q | -q | --enable-quadmath Enable optional libquadmath support (default for Fortran)
s | -s | --min-size Optimize for minimum size
x | -x | --disable-cxx Disable optional C++ support
g | -g | --disable-isl Disable isl Library support (Graphite loop optimisations)
T | -T | --custom-vendor Sets a custom vendor for tuple, requires architecture to be set before
```
### Other Commands
```Shell
./mussel (command)
```
**(command)**:
```Shell
c | -c | --clean Clean mussel's build environment
h | -h | --help Display this help message
```

## Packages
1. `binutils`: 2.44
2. `gcc`: 14.2.0
3. `gmp`: 6.3.0
4. `isl`: 0.27
5. `linux`: 6.13.7 (**Optional** Linux Headers Support) (**Disabled** by default)
6. `mpc`: 1.3.1
7. `mpfr`: 4.2.2
8. `musl`: 1.2.5
9. `pkgconf`: 2.4.3 (**Optional** `pkg-config` Support) (**Disabled** by default)
## How Is `mussel` Doing It?
1. Install `musl` headers
2. Configure, build and install cross `binutils`
3. Configure, build and install cross `gcc` (with `libgcc-static`)
4. Configure, build and install `musl`
5. Build, and install `libgcc-shared`
## **Optional** Steps
- Build and install `libstdc++-v3` (**Optional** C++ Support) (**Enabled** by default)
- Build and install `libgomp` (**Optional** OpenMP Support) (**Disabled** by default)
- Build and install `libquadmath` (**Optional** Quadruple-precision Support)
(**Disabled** by default, **Enabled** for Fortran)
- Build and install `libgfortran` (**Optional** Fortran Support) (**Disabled** by default)
- Install `linux-headers` (**Optional** Linux Headers Support) (**Disabled** by default)
- Configure, build and install `pkgconf` (**Optional** `pkg-config` Support)
(**Disabled** by default)
### Using `mussel` With Host's `pkg-config` or `pkgconf`
The reason we included `pkgconf` with `mussel` as an **optional** step is
because we can easily configure the host's `pkg-config` or `pkgconf` to work
with `mussel` without having to build our own version of `pkg-config` or
`pkgconf`.
Here are the five magical environment variables that we need to set to configure
the host's `pkg-config` or `pkgconf` to work with `mussel`:
```Shell
export PKG_CONFIG_PATH=$MSYSROOT/usr/lib/pkgconfig:$MSYSROOT/usr/share/pkgconfig
export PKG_CONFIG_LIBDIR=$MSYSROOT/usr/lib/pkgconfig:$MSYSROOT/usr/share/pkgconfig
export PKG_CONFIG_SYSROOT_DIR=$MSYSROOT
export PKG_CONFIG_SYSTEM_INCLUDE_PATH=$MSYSROOT/usr/include
export PKG_CONFIG_SYSTEM_LIBRARY_PATH=$MSYSROOT/usr/lib
```
The last two I believe are `pkgconf` specific but setting them won't do any harm.
### Using `mussel` With Host's `meson`
`mussel` now provides cross-compilation configuration files for `meson` that
support all listed architectures, and a wrapper around host's `meson`
(`mussel-meson`) in an effort to make dealing with `meson` a bit easier.
