# Building and installation
|
||
|
|
|
||
|
|
You are generally recommended to use your distro's package manager to install
|
||
|
|
Notcurses; it is [available](https://repology.org/project/notcurses/versions)
|
||
|
|
prepackaged on many distributions. Otherwise, acquire the current source via
|
||
|
|
|
||
|
|
`git clone https://github.com/dankamongmen/notcurses.git`
|
||
|
|
|
||
|
|
## Prerequisites
|
||
|
|
|
||
|
|
### APT
|
||
|
|
|
||
|
|
On an APT-based distribution, run:
|
||
|
|
|
||
|
|
`apt-get install build-essential cmake libavformat-dev libavutil-dev libncurses-dev libreadline-dev libqrcodegen-dev libswscale-dev pandoc pkg-config`
|
||
|
|
|
||
|
|
If you want to build the Python wrappers, you'll also need:
|
||
|
|
|
||
|
|
`apt-get install python3-cffi python3-dev python3-pypandoc python3-setuptools`
|
||
|
|
|
||
|
|
If you want to build the Rust wrappers, you'll also need:
|
||
|
|
|
||
|
|
`apt-get install cargo bindgen`
|
||
|
|
|
||
|
|
### RPM
|
||
|

|
''FIXME''
|
||
|
|
|
||
|
|
## Building
|
||
|
|
|
||
|
|
* Create a subdirectory, traditionally `build`. Enter the directory.
|
||
|
|
* `cmake ..`. You might want to set e.g. `CMAKE_BUILD_TYPE`.
|
||
|
|
* `make`
|
||
|
|
* `make test`
|
||
|
|
* `make install`
|
||
|
|
|
||
|
|
The default multimedia engine is FFmpeg. You can select a different engine
|
||
|
|
using `USE_MULTIMEDIA`. Valid values are `ffmpeg`, `oiio` (for OpenImageIO),
|
||
|
|
or `none`. Without a multimedia engine, Notcurses will be unable to decode
|
||
|
|
images and videos.
|
||
|
|
|
||
|
|
Run unit tests with `make test` following a successful build. If you have unit
|
||
|
|
test failures, *please* file a bug including the output of
|
||
|
|
|
||
|
|
`./notcurses-tester -p ../data`
|
||
|
|
|
||
|
|
(`make test` also runs `notcurses-tester`, but hides important output).
|
||
|
|
|
||
|
|
To watch the bitchin' demo, run `make demo`. More details can
|
||
|
|
be found on the `notcurses-demo(1)` man page.
|
||
|
|
|
||
|
|
Install with `make install` following a successful build. This installs the C
|
||
|
|
core library, the C headers, the C++ library, and the C++ headers (note that
|
||
|
|
the C headers are C++-safe). It does not install the Python or Rust wrappers.
|
||
|
|
To install the Python wrappers (after installing the core library), run:
|
||
|
|
|
||
|
|
```
|
||
|
|
cd cffi
|
||
|
|
python setup.py build
|
||
|
|
python setup.py install
|
||
|
|
```
|
||
|
|
|
||
|
|
The Python wrappers are also available from [PyPi](https://pypi.org/project/notcurses/). To install the low-level Rust
|
||
|
|
wrappers (`libnotcurses-sys`), run:
|
||
|
|
|
||
|
|
```
|
||
|
|
cd rust
|
||
|
|
cargo build
|
||
|
|
cargo install
|
||
|
|
```
|
||
|
|
|
||
|
|
The Rust wrappers are also available from [crates.io](https://crates.io/crates/libnotcurses-sys/).
|
||
|
|
|
||
|
|
### Build options
|
||
|
|
|
||
|
|
To set the C compiler, export `CC`. To set the C++ compiler, export `CXX`. The
|
||
|
|
`CMAKE_BUILD_TYPE` CMake variable can be defined to any of its standard values,
|
||
|
|
but must be `Debug` for use of `USE_COVERAGE`.
|
||
|
|
|
||
|
|
* `DFSG_BUILD`: leave out all content considered non-free under the Debian Free
|
||
|
|
Software Guidelines
|
||
|
|
* `BUILD_TESTING`: build test targets
|
||
|
|
* `USE_COVERAGE`: build coverage support (for developers, requires use of Clang)
|
||
|
|
* `USE_DOCTEST`: build `notcurses-tester` with Doctest, requires `BUILD_TESTING`
|
||
|
|
* `USE_DOXYGEN`: build interlinked HTML documentation with Doxygen
|
||
|
|
* `USE_MULTIMEDIA`: `ffmpeg` for FFmpeg, `oiio` for OpenImageIO, `none` for none
|
||
|
|
* `USE_PANDOC`: build man pages with pandoc
|
||
|
|
* `USE_POC`: build small, uninstalled proof-of-concept binaries
|
||
|
|
* `USE_QRCODEGEN`: build qrcode support via libqrcodegen
|
||
|
|
* `USE_STATIC`: build static libraries (in addition to shared ones)
