# makepkg
makepkg is a tool for creating [pacman](Pacman.md) packages based on [PKGBUILD](PKGBUILD.md) files.
## Configuration
The system configuration is available in `/etc/makepkg.conf`, but user-specific changes can be made in `$XDG_CONFIG_HOME/pacman/makepkg.conf` or `~/.makepkg.conf`. Also, system wide changes can be made with a drop-in file `/etc/makepkg.conf.d/makepkg.conf`. It is recommended to review the configuration prior to building packages.
> **Tip**: devtools helper scripts for building packages in a clean chroot use the `/usr/share/devtools/makepkg.conf.d/arch.conf` configuration file instead.

## Usage
Make a package:
```shell
makepkg
```
Make a package and install its dependencies:
```shell
makepkg --syncdeps
```
Make a package, install its dependencies then install it to the system:
```shell
makepkg --syncdeps --install
```
Make a package, but skip checking the source's hashes:
```shell
makepkg --skipchecksums
```
Clean up work directories after a successful build:
```shell
makepkg --clean
```
Verify the hashes of the sources:
```shell
makepkg --verifysource
```
## Options
| Option | Description |
| ------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `-A, --ignorearch` | Ignore a missing or incomplete arch field in the build script |
| `-c, --clean` | Clean up leftover work files and directories after a successful build |
| `-d, --nodeps` | Do not perform any dependency checks. This will let you override and ignore any dependencies required. There is a good chance this option will break the build process if all of the dependencies are not installed |
| `-e, --noextract` | Do not extract source files or run the prepare() function (if present); use whatever source already exists in the $srcdir/ directory. This is handy if you want to go into $srcdir/ and manually patch or tweak code, then make a package out of the result. Keep in mind that creating a patch may be a better solution to allow others to use your [PKGBUILD](PKGBUILD.md). |
| `--skipinteg` | Do not perform any integrity checks (checksum and [PGP](../../../cryptography/GPG.md)) on source files |
| `--skipchecksums` | Do not verify checksums of source files |
| `--skippgpcheck` | Do not verify [PGP](../../../cryptography/GPG.md) signatures of source files |
| `-i, --install` | Install or upgrade the package after a successful build using [pacman](Pacman.md) |
| `-o, --nobuild` | Download and extract files, run the prepare() function, but do not build them. Useful with the `--noextract` option if you wish to tweak the files in $srcdir/ before building |
| `-r, --rmdeps` | Upon successful build, remove any dependencies installed by makepkg during dependency auto-resolution and installation |
| `-s, --syncdeps` | Install missing dependencies using [pacman](Pacman.md). When build-time or run-time dependencies are not found, [pacman](Pacman.md) will try to resolve them. If successful, the missing packages will be downloaded and installed |
| `-C, --cleanbuild` | Remove the $srcdir before building the package |
| `-f, --force` | Overwrite package if it already exists |
| `--noarchive` | Do not create the archive at the end of the build process. This can be useful to test the package() function or if your target distribution does not use [pacman](Pacman.md) |
| `--sign` | Sign the resulting package with [gpg](../../../cryptography/GPG.md) |
| `--nosign` | Do not create a signature for the built package |
| `--key <key>` | Specify a key to use when signing packages |
| `--noconfirm` | (Passed to [pacman](Pacman.md)) Prevent [pacman](Pacman.md) from waiting for user input before proceeding with operations |
## Misc
### Using mold linker
[mold](../../development/mold.md) is a drop-in replacement for ld/lld linkers, which claims to be significantly faster.
To use mold, append `-fuse-ld=mold` to `LDFLAGS`. For example:
```sh
# /etc/makepkg.conf
LDFLAGS="... -fuse-ld=mold"
```
To pass extra options to mold, additionally add those to `LDFLAGS`. For example:
```sh
# /etc/makepkg.conf
LDFLAGS="... -fuse-ld=mold -Wl,--separate-debug-file"
```
To use mold for Rust packages, append `-C link-arg=-fuse-ld=mold` to `RUSTFLAGS`. For example:
```sh
# /etc/makepkg.conf.d/rust.conf
RUSTFLAGS="... -C link-arg=-fuse-ld=mold"
```
### Parallel compilation
The make build system uses the `MAKEFLAGS` environment variable to specify additional options for make. The variable can also be set in the `makepkg.conf` file.
Users with multi-core/multi-processor systems can specify the number of jobs to run simultaneously. This can be accomplished with the use of `nproc` to determine the number of available processors, e.g.
```sh
MAKEFLAGS="--jobs=$(nproc)".
```
Some `PKGBUILDs` specifically override this with `-j1`, because of race conditions in certain versions or simply because it is not supported in the first place.
### Building from files in memory
As compiling requires many I/O operations and handling of small files, moving the working directory to a [tmpfs](../../../linux/filesystems/tmpFS.md) may bring improvements in build times.
The `BUILDDIR` variable can be temporarily exported to makepkg to set the build directory to an existing tmpfs. For example:
```sh
BUILDDIR=/tmp/makepkg makepkg
```
Persistent configuration can be done in `makepkg.conf` by uncommenting the `BUILDDIR` option, which is found at the end of the BUILD ENVIRONMENT section in the default `/etc/makepkg.conf` file. Setting its value to e.g. `BUILDDIR=/tmp/makepkg` will make use of the Arch's default `/tmp` temporary file system.
> **Note:**
> - Avoid compiling larger packages in tmpfs to prevent running out of memory.
> - The tmpfs directory must be mounted without the `noexec` option, otherwise it will prevent built binaries from being executed.
> - Keep in mind that packages compiled in tmpfs will not persist across reboot. Consider setting the `PKGDEST` option appropriately to move the built package automatically to a persistent directory.
### Generate new checksums
Install `pacman-contrib` and run the following command in the same directory as the [PKGBUILD](./PKGBUILD.md) file to generate new checksums:
```sh
updpkgsums
```
`updpkgsums` uses `makepkg --geninteg` to generate the checksums.
The checksums can also be obtained with e.g `sha256sum` and added to the `sha256sums` array by hand.
### Build from local source files
If you want to make changes to the source code you can download the source code without building the package by using the `-o, --nobuild` Download and extract files only option.
```sh
makepkg -o
```
You can now make changes to the sources and then build the package by using the `-e, --noextract` Do not extract source files (use existing `$srcdir/` dir) option. Use the `-f` option to overwrite already built and existing packages.
```sh
makepkg -ef
```
