Building Slic3r PE on Mac OS
To build Slic3r PE on Mac OS, you will need to install XCode, CMake (available on Brew) and possibly git.
Dependencies
Slic3r comes with a set of CMake scripts to build its dependencies, it lives in the deps directory.
Open a terminal window and navigate to Slic3r sources directory and then to deps.
Use the following commands to build the dependencies:
mkdir build
cd build
cmake ..
make
This will create a dependencies bundle inside the build/destdir directory.
You can also customize the bundle output path using the -DDESTDIR=<some path> option passed to cmake.
Warning: Once the dependency bundle is installed in a destdir, the destdir cannot be moved elsewhere. (This is because wxWidgets hardcodes the installation path.)
Building Slic3r
If dependencies are built without errors, you can proceed to build Slic3r itself. Go back to top level Slic3r sources directory and use these commands:
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH="$PWD/../deps/build/destdir/usr/local"
The CMAKE_PREFIX_PATH is the path to the dependencies bundle but with /usr/local appended - if you set a custom path
using the DESTDIR option, you will need to change this accordingly. Warning: the CMAKE_PREFIX_PATH needs to be an absolute path.
The CMake command above prepares Slic3r for building from the command line. To start the build, use
make -jN
where N is the number of CPU cores, so, for example make -j4 for a 4-core machine.
Alternatively, if you would like to use XCode GUI, modify the cmake command to include the -GXcode option:
cmake .. -GXcode -DCMAKE_PREFIX_PATH="$PWD/../deps/build/destdir/usr/local"
and then open the Slic3r.xcodeproj file.
This should open up XCode where you can perform build using the GUI or perform other tasks.
Note on Mac OS X SDKs
By default Slic3r builds against whichever SDK is the default on the current system.
This can be customized. The CMAKE_OSX_SYSROOT option sets the path to the SDK directory location
and the CMAKE_OSX_DEPLOYMENT_TARGET option sets the target OS X system version (eg. 10.14 or similar).
Note you can set just one value and the other will be guessed automatically.
In case you set both, the two settings need to agree with each other. (Building with a lower deployment target
is currently unsupported because some of the dependencies don't support this, most notably wxWidgets.)
Please note that the CMAKE_OSX_DEPLOYMENT_TARGET and CMAKE_OSX_SYSROOT options need to be set the same
on both the dependencies bundle as well as Slic3r PE itself.
Official Mac Slic3r builds are currently built against SDK 10.9 to ensure compatibility with older Macs.
Warning: XCode may be set such that it rejects SDKs bellow some version (silently, more or less). This is set in the property list file
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Info.plist
To remove the limitation, simply delete the key MinimumSDKVersion from that file.
