Build Piccolo

Build on Windows

You may execute the build_windows.bat. This batch file will generate the projects, and build the Release config of Piccolo Engine automatically. After successful build, you can find the PiccoloEditor.exe at the bin directory.

Or you can use the following command to generate the Visual Studio project firstly, then open the solution in the build directory and build it manually.

cmake -S . -B build

Build on macOS

The following build instructions only tested on specific hardware of x86_64, and do not support M1 chips. For M1 compatible, we will release later.

To compile Piccolo, you must have the most recent version of Xcode installed. Then run 'cmake' from the project's root directory, to generate a project of Xcode.

cmake -S . -B build -G "Xcode"

and you can build the project with

cmake --build build --config Release

Or you can execute the build_macos.sh to build the binaries.

Build on Ubuntu 20.04

You can execute the build_linux.sh to build the binaries.

Extra

Generate Compilation Database

You can build compile_commands.json with the following commands when Unix Makefiles generaters are avaliable. compile_commands.json is the file required by clangd language server, which is a backend for cpp lsp-mode in Emacs.

For Windows:

cmake -DCMAKE_TRY_COMPILE_TARGET_TYPE="STATIC_LIBRARY" -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -S . -B compile_db_temp -G "Unix Makefiles"
copy compile_db_temp\compile_commands.json .
