|---|
| 2 | |
|---|
| 3 | ## Overview |
|---|
| 4 | |
|---|
| 5 | A terminal emulator widget for Qt 5. |
|---|
| 6 | |
|---|
| 7 | QTermWidget is an open-source project originally based on the KDE4 Konsole application, but it took its own direction later on. |
|---|
| 8 | The main goal of this project is to provide a Unicode-enabled, embeddable Qt widget for using as a built-in console (or terminal emulation widget). |
|---|
| 9 | |
|---|
| 10 | It is compatible with BSD, Linux and OS X. |

| 44 | ## Installation |
|---|
| 45 | |
|---|
| 46 | ### Compiling sources |
|---|
| 47 | |
|---|
| 48 | The only runtime dependency is qtbase ≥ 5.12.0. |
|---|
| 49 | Build dependencies are as follows: |
|---|
| 50 | - CMake ≥ 3.1.0 serves as the build system and therefore needs to be present to compile. |
|---|
| 51 | - The latest [lxqt-build-tools](https://github.com/lxqt/lxqt-build-tools/) is also needed for compilation. |
|---|
| 52 | - Git is needed to optionally pull latest VCS checkouts. |
|---|
| 53 | |
|---|
| 54 | Code configuration is handled by CMake. CMake variable `CMAKE_INSTALL_PREFIX` will normally have to be set to `/usr`, depending on the way library paths are dealt with on 64bit systems. Variables like `CMAKE_INSTALL_LIBDIR` may have to be set as well. |
|---|
| 55 | |
|---|
| 56 | To build, run `make`. To install, run `make install` which accepts variable `DESTDIR` as usual. |
|---|
| 57 | |
|---|
| 58 | To build PyQt bindings, build this library first, and then invoke `sip-wheel` in pyqt/ directory. Environment variables `CXXFLAGS` and `LDFLAGS` can be used to specify non-installed or non-standard directories for headers and shared libraries, and the built Python wheel can be installed by standard tools like `pip`. See [the CI script](.ci/build.sh) for a complete example. |
|---|
| 59 | |
|---|
| 60 | ### Binary packages |
|---|
| 61 | |
|---|
| 62 | The library is provided by all major Linux distributions. This includes Arch Linux, Debian, Fedora, openSUSE and all of their children, given they use the same package repositories. |
|---|
| 63 | Just use the distributions' package managers to search for string `qtermwidget`. |
|---|
