# gst-build
|
|
|
|
GStreamer [meson](http://mesonbuild.com/) based repositories aggregrator
|
|
|
|
You can build GStreamer and all its modules at once using
|
|
meson and its [subproject](https://github.com/mesonbuild/meson/wiki/Subprojects) feature.
|
|
|
|
## Getting started
|
|
|
|
### Install meson and ninja
|
|
|
|
You should get meson through your package manager or using:
|
|
|
|
$ pip3 install --user meson
|
|
|
|
You should get `ninja` using your package manager or downloading it from
|
|
[here](https://github.com/ninja-build/ninja/releases).
|
|
|
|
### Build GStreamer and its modules
|
|
|
|
You can get all GStreamer built running:
|
|
|
|
```
|
|
mkdir build/ && meson build && ninja -C build/
|
|
```
|
|
|
|
NOTE: on fedora (and maybe other distributions) replace `ninja` with `ninja-build`
|
|
|
|
# Development environment
|
|
|
|
## Uninstalled environment
|
|
|
|
gst-build also contains a special `uninstalled` target that lets you enter an
|
|
uninstalled development environment where you will be able to work on GStreamer
|
|
easily. You can get into that environment running:
|
|
|
|
```
|
|
ninja -C build/ uninstalled
|
|
```
|
|
|
|
If your operating system handles symlinks, built modules source code will be
|
|
available at the root of `gst-build/` for example GStreamer core will be in
|
|
`gstreamer/`. Otherwise they will be present in `subprojects/`. You can simply
|
|
hack in there and to rebuild you just need to rerun `ninja -C build/`.
|
|
|
|
## Update git subprojects
|
|
|
|
We added a special `update` target to update subprojects (it uses `git pull
|
|
--rebase` meaning you should always make sure the branches you work on are
|
|
following the right upstream branch, you can set it with `git branch
|
|
--set-upstream-to origin/master` if you are working on `gst-build` master
|
|
branch).
|
|
|
|
Update all GStreamer modules and rebuild:
|
|
|
|
```
|
|
ninja -C build/ update
|
|
```
|
|
|
|
Update all GStreamer modules without rebuilding:
|
|
|
|
```
|
|
ninja -C build/ git-update
|
|
```
|
|
|
|
|
|
## Add information about GStreamer development environment in your prompt line
|
|
|
|
### Bash prompt
|
|
|
|
We automatically handle `bash` and set `$PS1` accordingly
|
|
|
|
### Zsh prompt
|
|
|
|
In your `.zshrc`, you should add something like:
|
|
|
|
```
|
|
export PROMPT="$GST_ENV-$PROMPT"
|
|
```
|
|
|
|
### Using powerline
|
|
|
|
In your powerline theme configuration file (by default in
|
|
`{POWERLINE INSTALLATION DIR}/config_files/themes/shell/default.json`)
|
|
you should add a new environment segment as follow:
|
|
|
|
```
|
|
{
|
|
"function": "powerline.segments.common.env.environment",
|
|
"args": { "variable": "GST_ENV" },
|
|
"priority": 50
|
|
},
|
|
```
