# Bazel rules for Qt
These Bazel rules and BUILD targets make it easy to use Qt from C++ projects built with Bazel.
Note that unlike many libraries used through Bazel, it requires Qt to be installed when building the application.
Also keep in mind that these rules only allow to link Qt dynamically.
In addition in the case of Linux it also requires Qt to be installed on the system when running it.
For Windows, it is not needed to have Qt installed in the system to run your program. The needed DLL files are copied to the output folder to make it self-contained. However, Qt is still dynamically linked.
## Platform support
This project currently works on Linux, Windows, and macOS.
## Usage
You can either copy the `qt.BUILD` and `qt.bzl` files into your project, add this project as a submodule if you're using git, or use a `git_repository` rule to fetch the rules.
Configure your `WORKSPACE` to include the Qt libraries:
```python
# WORKSPACE
load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")
git_repository(
name = "com_justbuchanan_rules_qt",
remote = "https://github.com/justbuchanan/bazel_rules_qt.git",
branch = "master",
)
load("@com_justbuchanan_rules_qt//:qt_configure.bzl", "qt_configure")
qt_configure()
load("@local_config_qt//:local_qt.bzl", "local_qt_path")
new_local_repository(
name = "qt",
build_file = "@com_justbuchanan_rules_qt//:qt.BUILD",
path = local_qt_path(),
)
load("@com_justbuchanan_rules_qt//tools:qt_toolchain.bzl", "register_qt_toolchains")
register_qt_toolchains()
```
Use the build rules provided by `qt.bzl` to build your project. See `qt.bzl` for which rules are available.
```python
# BUILD
load("@com_justbuchanan_rules_qt//:qt.bzl", "qt_cc_library", "qt_ui_library")
qt_cc_library(
name = "MyWidget",
srcs = ["MyWidget.cc"],
hdrs = ["MyWidget.h"],
deps = ["@qt//:qt_widgets"],
)
qt_ui_library(
name = "mainwindow",
ui = "mainwindow.ui",
deps = ["@qt//:qt_widgets"],
)
cc_binary(
name = "main",
srcs = ["main.cpp"],
copts = ["-fpic"],
deps = [
"@qt//:qt_widgets",
":MyWidget",
":mainwindow",
],
)
```
