Configure the build to use mingw

git clone
cd lmms
mkdir build
cd build

Create a Windows desktop installer

make -j4 package

... see more compiling options here.

Windows MSVC

Warning, MSVC building is still experimental. Some plugins aren't available when compiling with MSVC.

Use the master branch, MSVC is not supported on stable-1.2.

git clone -b master


  1. Install Visual Studio Community (if you don't already have it) from here:
    • Make sure to download the Desktop Development with C++ tools. If you already have Visual Studio downloaded, you can 'modify' it with the Visual Studio Installer.
    • Alternatively, you can use Visual Studio build tools (which includes the compiler and the other stuff but without the ide).
  2. Install Qt Open Source version from here:
    • Follow the installer and create a free account if you do not have one already.
    • When you get to the 'Select Components' stage, select version 5.15.2 and just select 'MSVC 2019 64-bit' and 'MSVC 2019 32-bit'.
      • If you only want to build for 32-bit, you can just select the 32-bit option.
      • If you want to build for 64-bit, you need to also install the 32-bit package as well to support 32-bit VSTs.
    • Expand the 'Developer and Designer Tools' section and unselect 'CMake 64-bit' (we will install this manually in the next step) and 'Ninja' (this comes by default with Visual Studio). Only 'Qt Creator CDB Debugger Support' and 'Debugging Tools for Windows' should be left selected, along with the mandatory 'Qt Creator'.
  3. Install CMake from here:
    • This is included in visual studio, do we really need to download it here as well...?
  4. Install Git (if you don't already have it) from here:

Installing dependencies

  1. Install Vcpkg at C:\
    cd C:\
    git clone
    cd vcpkg
  2. Install LMMS dependencies using Vcpkg
    .\vcpkg install --triplet=x64-windows fftw3 libsamplerate libsndfile lilv lv2 sdl2 fluidsynth fltk
    Replace x64-windows with x86-windows if you want to build 32-bit version instead of 64-bit.

Compile using Qt Creator

Skip to the next section if you want to use the command line instead.

  1. Open up Qt Creator

  2. Go to Tools->Options->Build & Run->Kits. Qt Creator should have detected your Qt installation automatically. We need to make adjustments to it so that CMake finds the libraries installed using Vcpkg. Select the detected kit and click Change... next to "CMake configuration":

  3. Assuming Vcpkg is installed at C:\vcpkg, add ;C:\vcpkg\installed\x64-windows to the line starting with CMAKE_PREFIX_PATH(or -DCMAKE_PREFIX_PATH):

  4. Exit the options and open CMakeLists.txt in the Qt creator window.

Compile using the command line

Configure using CMake. Pass in Visual Studio 17 2022 (or the version you have in your machine) as the build tool. Also pass in the path to Qt 5.15.2 MSVC 2019 64bit using -DCMAKE_PREFIX_PATH and installed Vcpkg to C:/vcpkg. Change paths accordingly. For 32 bit qt, we use another argument -DQT_32_PREFIX=<path to qt install>/msvc2019

cd lmms
mkdir build
cd build
cmake .. -G "Visual Studio 17 2022" -DCMAKE_PREFIX_PATH=C:/Qt/5.15.2/msvc2019_64 -DQT_32_PREFIX=C:/Qt/5.15.2/msvc2019 -DCMAKE_TOOLCHAIN_FILE=C:/vcpkg/scripts/buildsystems/vcpkg.cmake

If you've build and installed qt5 in vcpkg, you don't need to specify CMAKE_PREFIX_PATH. CMake will find the version inside vcpkg

If configuring succeeded, compile using

cmake --build . --config Release

The building part is over but LMMS fails to run at this stage. You might get "qt5 dlls missing" errors. To fix that, you need to install LMMS using cmake. I am installing LMMS at C:/lmms for this tutorial.

cmake --install . --config Release --prefix=C:/lmms

If LMMS still gives a "dlls missing" error, or if you saw a "cannot analyze prerequisites" error in the previous two steps, you may need to switch to the VS Developer Command Prompt in Visual Studio 2022 to run the commands.

Compile using MSVC IDE

If you completed the first cmake command in the section above, it will have also created lmms.sln in your build directory.

By default when you generate an msvc solution file, cmake will be configured for release. This means the release version of the libraries in vcpkg will be used even if you choose debug in visual studio. You can use a utility like cmake-gui to change the build type from release to debug and then configure and generate again.

You can also use cmake-gui to create the initial solution file. When you configure for the first time, select your compiler and select the option: Select toolchain file for cross-compiling. The file you should be using is <vcpkg-install-path>\scripts\buildsystems\vcpkg.cmake

Alternately, Visual Studio should automatically detect that you are running a CMAKE project if you open the root LMMS folder. You will however need to set the QT path in CMakeSettings.json. This can easily be managed by right clicking on CMakeSettings.json and selecting Edit CMake Settings. Then scroll down to the Qt5_DIR variable and browser for the QT installation folder, then go into the version you have downloaded and navigate to msvc2019_64/lib/cmake. You will also need to set the locations for the libraries you downloaded through vcpkg, which can be found in the packages folder of wherever you installed vcpkg. Click 'Show advanced variables' to ensure you always see the variables you need. Try and populate all the missing _DIR (root folder), _INCLUDE_DIR ('include' folder), and _LIBRARY (the .lib file in 'library'). When inputting paths, use \ in the paths and not / (the 'browse' button seems to use / which don't seem to save/properly).

Note: Visual Studio can be very strange, and sometimes you may have to do some fudging around with saving the CMakeSettings.json file, cleaning, rebuilding, restarting visual studio etc to get lmms building…

If you have WSL installed, you can use the Linux commands instead.

NOTE: You have to type bash into Command Prompt in order to use Linux commands.

Windows MSYS

⚠️ Warning: This tutorial is very outdated and is left here for reference only. Configure a mingw-w64 environment in Windows using msys2 from Start Menu.

I know what I'm doing, show the tutorial

Setup Shell

Setup a unix-like shell environment using msys2

First, download, install and launch msys2 from Start Menu (or manually from msys2_shell.cmd).

Important The msys2 mirrors have reliability problems and this causes packages to fail during download. At any time setting up dependencies if an error occurs, try the command again. For longer tasks, scroll up and look for them.

# From msys2 desktop application, fetch all available packages
pacman -Sy

# Update essential utilities
pacman --needed -S bash pacman pacman-mirrors msys2-runtime

# Restart msys2 (mandatory)

Setup Basic Build Environment

Using msys2 from Start Menu

# Fetch list of outdated packages.
# If this errors out, follow instructions carefully and try again.
pacman -Su

# "Errors occurred, no packages were upgraded" is normal, just try again

# Download and install the 32-bit and 64-bit toolchains (about 85MB)
pacman -S mingw-w64-x86_64-gcc mingw-w64-i686-gcc

# Download and install dependencies (about 1.6GB, 8.2GB installed)
pacman -S git mingw-w64-x86_64-pkg-config make cmake wget p7zip gzip tar binutils mingw-w64-x86_64-qt4 mingw-w64-i686-qt4 gdb diffutils perl-List-MoreUtils perl-XML-Parser

Qt5 hasn't been tested and will likely cause problems but can be provided by installing mingw-w64-x86_64-qt5 mingw-w64-i686-qt5 instead of qt4 packages.

Qt5 egg

# Download and install dependencies (about 1.6GB, 8.2GB installed)
pacman -S git mingw-w64-x86_64-pkg-config make cmake wget p7zip gzip tar binutils mingw-w64-x86_64-qt5 mingw-w64-i686-qt5 gdb diffutils perl-List-MoreUtils perl-XML-Parser

Setup Remaining Dependencies

Using Mingw-w64 from Start Menu (or manually via mingw64.exe).

Important The following commands won't work from msys2 console. It needs to be mingw!

# Delete any old helper scripts
rm -f

# Download latest helper script from master
wget --no-check-certificate

# Run the helper script. This will automatically:
# - Download/extract/install the Ubuntu mingw ppa (400MB)
# - Download/compile any conflicting libraries
# - Configure git for use with msys

# "cp: cannot create regular file" is normal, please ignore

# There will be warnings during library compilations, please ignore

Setup Additional Workarounds

From cmd.exe, as Administrator

# Create symlinks, moc.exe work-around
# - Adjust paths if msys2 was installed in non-standard location
mklink /d %SystemDrive%\mingw64 %SystemDrive%\msys64\mingw64
mklink /d %SystemDrive%\mingw32 %SystemDrive%\msys64\mingw32
mklink /d %SystemDrive%\home %SystemDrive%\msys64\home

    ...done installing? Next, clone the source code

If you have WSL installed, you can use the Linux commands instead.

NOTE: You have to type bash into Command Prompt in order to use Linux commands.
