Building Brassica

Building

Brassica can be built using much the same process on both Windows and Linux. (And probably Mac, though I haven’t tried it there.) First, build the command-line interface with Cabal (which can be installed using GHCup):

cabal build exe:brassica

Next, build the GUI interface, in ./gui/brassica-gui. Brassica uses Qt version 6, and relies on CMake for building. The CMake configuration uses cabal to find the location of the command-line executable, so make sure cabal is on your PATH first. Especially on Windows, it may be easiest to open the project in Qt Creator and use that for building.

Alternately, you can use CMake directly. On Linux this is simple:

cd gui/brassica-gui
cmake -S . -B ../build
cd ../build
make

On Windows it is more involved, since you need to set the appropriate paths, substituting <version> as appropriate:

cd gui/brassica-gui
set PATH=%PATH%;C:\Qt\Tools\Ninja\;C:\Qt\Tools\mingw1120_64\bin
C:\Qt\Tools\CMake_64\bin\cmake.exe -S . -B ../build -G Ninja -DCMAKE_BUILD_TYPE:String=Release -DQT_QMAKE_EXECUTABLE:STRING=C:/Qt/<version>/mingw81_64/bin/qmake.exe -DCMAKE_PREFIX_PATH:STRING=C:/Qt/<version>/mingw_64 -DCMAKE_C_COMPILER:STRING=C:/Qt/Tools/mingw<version>/bin/gcc.exe -DCMAKE_CXX_COMPILER:STRING=C:/Qt/Tools/mingw<version>/bin/g++.exe
cd ../build
ninja

Deployment

On Linux, the preferred deployment method is using AppImages. First download linuxdeploy and linuxdeploy-plugin-qt. Then run cabal build, cmake and make as described above. Then, to build the AppImage, run:

linuxdeploy-x86_64.AppImage --executable ./brassica-gui --appdir AppDir -d ../brassica-gui/brassica.desktop -i ../brassica-gui/brassica.png --plugin qt
cp ./brassica AppDir/usr/bin
linuxdeploy-x86_64.AppImage --appdir AppDir --output appimage

(You may need to export QMAKE=/usr/bin/qmake6 if you’re using a distribution such as Debian where Qt 5 is the default.)

Similarly the CLI can be deployed to an AppImage with something like:

linuxdeploy-x86_64.AppImage --executable brassica --appdir AppDirCLI path/to/brassica-gui/brassica.desktop -i path/to/brassica-gui/brassica.png --output appimage

On Windows, first copy brassica.exe, brassica-pb.exe and brassica-gui.exe into .\deploy, and .\examples into .\deploy\examples. Then use windeployqt on brassica-gui.exe to copy over the relevant files for Qt. Finally, use NSIS with the given installer.nsi to generate an installer.

Online version

Building the online version of Brassica is slightly more difficult as it requires the WebAssembly backend of GHC. It is easiest to get this using GHCup’s WASM cross bindists. You will also need Wizer to pre-initialise the WASM binary, and npm for JavaScript package management.

Then:

  1. In ./gui/brassica-interop-wasm, run the following commands:

    cabal build --project-file=cabal-wasm.project brassica-interop-wasm
wizer --allow-wasi --wasm-bulk-memory true "$(cabal --project-file=cabal-wasm.project list-bin -v0 brassica-interop-wasm)" -o "./dist/brassica-interop-wasm.wasm"

    This will create a file ./gui/brassica-interop-wasm/dist/brassica-interop-wasm.wasm containing the WASM binary.

    (Note: it can also be convenient to set CABAL_DIR so that WASM packages are installed to a different location.)

  2. In ./gui/brassica-web, run mkdir dist; ./cpfiles to copy the asset files into dist. Note that you’ll need to redo this every time you update a static file (HTML or CSS or WASM)!

  3. Install JavaScript dependencies using npm install.

    Now you can use webpack to bundle the JavaScript files. For instance, use npx webpack serve to run a development server, or npx webpack --mode=production to prepare a release.
