# cpkg
[](https://matrix.hackage.haskell.org/package/cpkg)

`cpkg` is a build tool for C with a particular emphasis on cross compilation.
It is configured using
[Dhall](http://github.com/dhall-lang/dhall-haskell).
By considering a package to be a *function* taking a `cpkg`-supplied
installation directory to a series of steps, we can effectively package
C projects with diverse build systems and handle dependencies between them.
This tool provides reasonably good support for cross-compilation of C projects
and packages. It is not a full-fledged package manager.

## Installation
```
cabal new-install cpkg
```
### Shell Completions
Add the following to your `~/.bashrc` for shell completions:
```
eval "$(cpkg --bash-completion-script cpkg)"
```
### Packages
To view available packages, use `cpkg list`
```

## Example
To install `tar`:
```
cpkg install tar
```
To install `emacs`:
```
cpkg install emacs
```
### Configuration
Here is the configuration for Lua:
```dhall
let prelude = https://raw.githubusercontent.com/vmchale/cpkg/master/dhall/cpkg-prelude.dhall
in
let lua =
λ(v : List Natural) →
let printLuaOS =
λ(os : types.OS) →
merge
{ FreeBSD = λ(_ : {}) → "freebsd"
, OpenBSD = λ(_ : {}) → "bsd"
, NetBSD = λ(_ : {}) → "bsd"
, Solaris = λ(_ : {}) → "solaris"
, Dragonfly = λ(_ : {}) → "bsd"
, Linux = λ(_ : {}) → "linux"
, Darwin = λ(_ : {}) → "macosx"
, Windows = λ(_ : {}) → "mingw"
, Redox = λ(_ : {}) → "generic"
, Haiku = λ(_ : {}) → "generic"
, IOS = λ(_ : {}) → "generic"
, AIX = λ(_ : {}) → "generic"
, Hurd = λ(_ : {}) → "generic"
, Android = λ(_ : {}) → "generic"
, NoOs = λ(_ : {}) → "c89"
}
os
in
let luaBuild =
λ(cfg : types.BuildVars) →
let cc = prelude.mkCCArg cfg
in
let ldflags =
(prelude.mkLDFlags cfg.linkDirs).value
in
let cflags =
(prelude.mkCFlags cfg.includeDirs).value
in
let os =
prelude.osCfg cfg
in
[ prelude.call (prelude.defaultCall ⫽ { program = "make"
, arguments = cc # [ printLuaOS os, "MYLDFLAGS=${ldflags}", "MYCFLAGS=${cflags}", "MYLIBS=-lncurses" ]
})
]
in
let luaInstall =
λ(cfg : types.BuildVars) →
[ prelude.call (prelude.defaultCall ⫽ { program = "make"
, arguments = [ "install", "INSTALL_TOP=${cfg.installDir}" ]
}) ]
# prelude.symlinkBinaries [ "bin/lua", "bin/luac" ]
in
prelude.simplePackage { name = "lua", version = v } ⫽
{ pkgUrl = "http://www.lua.org/ftp/lua-${prelude.showVersion v}.tar.gz"
, configureCommand = prelude.doNothing
, buildCommand = luaBuild
, installCommand = luaInstall
, pkgDeps = [ prelude.unbounded "readline"
, prelude.unbounded "ncurses"
]
}
in
lua [5,3,5]
```
### Cabal Integration
After running
```
cpkg install libX11 --target=arm-linux-gnueabihf
cpkg install libXext --target=arm-linux-gnueabihf
cpkg install libXrandr --target=arm-linux-gnueabihf
cpkg install libXinerama --target=arm-linux-gnueabihf
cpkg install libXScrnSaver --target=arm-linux-gnueabihf
```
You can dump flags to be passed to cabal with
```
cpkg dump-cabal libX11 libXext libXrandr libXinerama libXScrnSaver --target=arm-linux-gnueabihf
```
which will produce something like
```
--extra-lib-dirs=/home/vanessa/.cpkg/arm-linux-gnueabihf/libX11-1.6.7-820c8166b4caadb/lib --extra-lib-dirs=/home/vanessa/.cpkg/arm-linux-gnueabihf/libXext-1.3.3-1bad0a89c6794a53/lib --extra-lib-dirs=/home/vanessa/.cpkg/arm-linux-gnueabihf/libXrandr-1.5.1-f58f951a622e5c2/lib --extra-lib-dirs=/home/vanessa/.cpkg/arm-linux-gnueabihf/libXinerama-1.1.4-516496f7e04d34be/lib --extra-lib-dirs=/home/vanessa/.cpkg/arm-linux-gnueabihf/libXScrnSaver-1.2.3-60f6993b79a87725/lib
```
This could be used, for example, to cross-compile `xmonad`, viz.
```
cabal new-install xmonad --with-ghc arm-linux-gnueabihf-ghc --with-ghc-pkg arm-linux-gnueabihf-ghc-pkg $(cpkg dump-cabal libX11 libXext libXrandr libXinerama libXScrnSaver --target=arm-linux-gnueabihf)
```
### Dhall Prelude
There is
a [prelude](https://github.com/vmchale/cpkg/blob/master/dhall/cpkg-prelude.dhall)
available containing functions which simplify the process of writing package
descriptions. As an example, we can install `sed`
```dhall
let prelude = https://raw.githubusercontent.com/vmchale/cpkg/master/dhall/cpkg-prelude.dhall
in
let sed =
λ(v : List Natural) →
prelude.makeGnuExe { name = "sed", version = v }
in
sed [4,5]
```
## Known Deficiencies
### Security
This tool is insecure.
### Performance
This tool is not performant.
### Dependency Solver
Currently, there is no dependency solver. It should be relatively easy to add
a version-based dependency solver to the code.
### Garbage Collection
Currently, there is no garbage collector à la `$ nix-collect-garbage`. This will
*not* be relatively easy to add, because it will require that the global package
index be re-implemented (ideally using a proper database).
