Building Audacity 2.4.2 on Debian 10 (with cmake 3.18)

[steve]

Audacity 2.4.2 requires cmake version 3.15 or later.
At time of writing, the Debian 10 repository version of cmake is 3.13.4-1, which is too old, so the first task is to install a more recent version of cmake.

1. Uninstall any version of cmake currently installed:

   Code: Select all

   sudo apt purge cmake

2. Download cmake-3.18.1-Linux-x86_64.sh from https://cmake.org/download/
3. Copy cmake-3.18.1-Linux-x86_64.sh to /usr/local

   Code: Select all

   sudo cp cmake-3.18.1-Linux-x86_64.sh /usr/local

4. Navigate to /usr/local and set the executable permission for cmake-3.18.1-Linux-x86_64.sh

   Code: Select all

   cd /usr/local
   sudo chmod +x cmake-3.18.1-Linux-x86_64.sh
   

5. Run the installation script:

   Code: Select all

   sudo sh cmake-3.18.1-Linux-x86_64.sh

6. Follow the on-screen instructions. Note that:
   1. You must respond "Y" when asked if you accept the license agreement
   2. Respond "n" when prompted:

      Code: Select all

      By default the CMake will be installed in:
        "/usr/local/cmake-3.18.1-Linux-x86_64"
      Do you want to include the subdirectory cmake-3.18.1-Linux-x86_64?
      Saying no will install in: "/usr/local" [Yn]:
      

7. Check the cmake version

   Code: Select all

   cmake --version

Once cmake 3.18 is installed, follow the Ubuntu 20.04 instructions to install Audacity: viewtopic.php?p=398471#p398471
