# Building in Mac OS X
|
|
|
|
Building in Mac OS X can be accomplished in just a few steps:
|
|
|
|
* Install general development tools (clang, make, git)
|
|
* Install cmake
|
|
* Checkout INAV sourcecode through git
|
|
* Build the code
|
|
|
|
## Install general development tools (clang, make, git)
|
|
|
|
Open up a terminal and run `make`. If it is installed already, you should see a message like this, which means that you
|
|
already have the required development tools installed:
|
|
|
|
```
|
|
make: *** No targets specified and no makefile found. Stop.
|
|
```
|
|
|
|
If it isn't installed yet, you might get a popup like this. If so, click the "install" button to install the commandline
|
|
developer tools:
|
|
|
|
|
|
|
|
If you just get an error like this instead of a helpful popup prompt:
|
|
|
|
```
|
|
-bash: make: command not found
|
|
```
|
|
|
|
Try running `xcode-select --install` instead to trigger the popup.
|
|
|
|
If that doesn't work, you'll need to install the XCode development environment [from the App Store][]. After
|
|
installation, open up XCode and enter its preferences menu. Go to the "downloads" tab and install the
|
|
"command line tools" package.
|
|
|
|
[from the App Store]: https://itunes.apple.com/us/app/xcode/id497799835

|
|
|
## Install cmake
|
|
|
|
The easiest way to install cmake's command line executable is via
|
|
[Homebrew](https://brew.sh) (a package manager for macOS). Go to their site
|
|
and follow their installation instructions.
|
|
|
|
Once Homebrew is installed, type `brew install cmake` in a terminal to install
|
|
cmake.
|
|
|
|
Alternatively, cmake binaries for macOS are available from
|
|
[cmake.org](https://cmake.org/download/). If you prefer installing it this way,
|
|
you'd have to manually add cmake's command line binary to your `$PATH`. Assuming
|
|
`CMake.app` has been copied to `/Applications`, adding the following line to
|
|
`~/.zshrc` would make the cmake command available.
|
|
|
|
```sh
|
|
export PATH=$PATH:/Applications/CMake.app/Contents/bin
|
|
```
|
|
|
|
## Ruby
|
|
|
|
Ruby is installed by default on macOS.
|
|
|
|
## Checkout INAV sourcecode through git
|
|
|
|
Enter your development directory and clone the [INAV repository][] using the "HTTPS clone URL" which is shown on
|
|
the right side of the INAV GitHub page, like so:
|
|
|
|
```
|
|
git clone https://github.com/iNavFlight/inav
|
|
```
|
|
|
|
This will download the entire INAV repository for you into a new folder called "inav".
|
|
|
|
[INAV repository]: https://github.com/iNavFlight/inav.git
|
|
|
|
## Build the code
|
|
|
|
Assuming you've just cloned the source code, you can switch your current
|
|
directory to INAV's source try by typing:
|
|
|
|
```sh
|
|
cd inav
|
|
```
|
|
|
|
Inside the INAV directory, create a new directory to store the built files. This
|
|
helps keeping everything nice and tidy, separating source code from artifacts. By
|
|
convention this directory is usually called `build`, but any name would work. Enter
|
|
the following command to create it and switch your working directory to it:
|
|
|
|
```sh
|
|
mkdir -p build && cd build
|
|
```
|
|
|
|
Now we need to configure the build by using the following command:
|
|
|
|
```sh
|
|
cmake ..
|
|
```
|
|
|
|
This will automatically download the required compiler for INAV, so it
|
|
might take a few minutes. Once it's finished without errors, you can
|
|
build the target that you want by typing `make target-name`. e.g.:
|
|
|
|
```sh
|
|
make -j8 MATEKF722 # Will build MATEKF722 target
|
|
```
|
|
|
|
A list of all the available targets can be displayed with:
|
|
|
|
```sh
|
|
make targets
|
|
```
|
|
|
|
Once the build completes, the correspondent `.hex` file will be found
|
|
in current directory (e.g. `build`) and it will be named as
|
|
`inav_x.y.z_TARGET.hex`. `x.y.z` corresponds to the INAV version number
|
|
while `TARGET` will be the target name you've just built. e.g.
|
|
`inav_2.6.0_MATEKF722.hex`. This is the file that can be flashed using
|
|
INAV Configurator.
|
|
|
|
## Updating to the latest source
|
|
|
|
If you want to erase your local changes and update to the latest version of the INAV source, enter your
|
|
INAV directory and run these commands to first erase your local changes, fetch and merge the latest
|
|
changes from the repository, then rebuild the firmware:
|
|
|
|
```sh
|
|
git reset --hard
|
|
git pull
|
|
|
|
make target-name # e.g. make MATEKF722
|
|
```
