Lv2

Required packages: lv2-dev liblilv-dev

VST

Install libraries for VST support On Ubuntu/mint/other stable distros, install wine from WineHQ. Follow the steps listed here
After setting up WineHQ, install the packages with the following commands:

sudo apt install libwine-dev gcc-multilib g++-multilib

if you still don't get vst support, try running sudo apt install --install-recommends wine-devel

note: It is possible to use wine-(stable, devel, or staging)

### Carla

Install libraries for [Carla](http://kxstudio.linuxaudio.org/Applications:Carla) support:
```bash
# Update software sources
sudo apt-get update

# Install required dependencies if needed
sudo apt-get install apt-transport-https gpgv wget

# Download kxstudio package file
wget https://launchpad.net/~kxstudio-debian/+archive/kxstudio/+files/kxstudio-repos_11.1.0_all.deb

# Install it
sudo dpkg -i kxstudio-repos_11.1.0_all.deb
sudo apt install -y carla

• Don't forget to install libraries for VST support here and Carla support here

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

Troubleshooting

CMake

Some project operations -- such as generating AppImages -- may require a newer version of CMake. To force a newer version, install from snap:

sudo snap install cmake --classic
alias cmake='snap run cmake'

# keywords: WARNING AppImage creation requires at least CMake 3.19

Unmet dependencies

Sometimes apt will not allow all packages to be installed simultaneously. (e.g. foo : Depends: bar (=1.0.0) but it is not going to be installed). Install them or resolve dependencies individually.

sudo apt install libfluidsynth-dev
sudo apt install libjack-jackd2-dev

# keywords: The following packages have unmet dependencies
# keywords: Unknown command PKG_GET_VARIABLE
# note: libsdl-dev might need a version number when installing dependencies. Example: libsdl1.2-dev 

This can also happen if you already have Jack1 installed on your system, and you're trying to install Jack2 development files. You should try installing Jack1 dev files instead:

sudo apt install libjack-dev

# keywords: The following packages have unmet dependencies

Both Jack1 and Jack2 work fine with LMMS, for differences between the two please consult the Jackaudio wiki.

qmake

If qmake --version shows an error:

sudo apt install qt5-default

# keywords: qmake: could not find a Qt installation of ''

ia32-libs

Older environments may complain that ia32-libs package has been removed. See this page for more information.

sudo apt install wine32

# keywords: ia32-libs package has been removed

Using build-dep

If you are unable to build LMMS after following the steps above, you may want to try apt-get's build-dep command.

This command will install required dependencies for a package.

For Ubuntu:

1. Edit /etc/apt/sources.list, and uncomment any deb-src entries.
2. sudo apt update
3. sudo apt build-dep lmms

For Linux Mint:

1. Open "Software Sources".
2. Flip the "Source code repositories" switch in the Official Repositories tab.
3. Update the apt cache when prompted.
4. Run sudo apt build-dep lmms.

Remember to comment out deb-src entries in /etc/apt/sources.list when you are finished, or all subsequent apt update commands will take twice as long
