For Windows, a typical installation of the SDK results in the following programs being installed:

Figure 1. MeVisLab Icons

	Note
	Debug versions can only be started if a development environment (Visual Studio) is installed on the computer.

For C++ module development, you can usually use a later Visual Studio version with a MeVisLab that was created for an earlier Visual Studio version.

There may also be differences between Visual Studio Express versions and the full Visual Studio versions (standard or professional). Make sure that the compiler version that you intend to use is supported by your Visual Studio installation.

For compilation, CMake is used. See the CMake Manual for further information.

	Note
	The macOS specific documentation is maintained as a separate document. The document for your specific version can be found here and the latest release version is available here.

This section shows how to handle MeVisLab on macOS:

Installing MeVisLab

Installation differs a little from other applications on macOS. Get MeVisLab from https://www.mevislab.de/download/.

	Note
	MeVisLab is not available for macOS in versions 3.4.3 and follow-up releases.

After downloading MeVisLab, you should double-click the downloaded image file.

A license window and the Finder open.

For most applications, you would drag MeVisLab to Applications directory.

For MeVisLab this link is missing.

You need to open Finder yourself and navigate to your Applications directory.

Right click on the Finder-Icon in your Dock and start a new instance.

Navigate to your (~/)Applications directory.

Now you should be able to drag and drop MeVisLab into the Applications folder.

MeVisLab is installed.

macOS currently does not trust MeVisLab. You will get the following dialog (depending on your language):

Figure 3. Trust MeVisLab

You need to open the Finder again, navigate to Applications directory and open MeVisLab via Context Menu.

Figure 4. Open MeVisLab

Once again a warning opens but this time you will be able to open nevertheless.

Figure 5. Open MeVisLab

Now you can start MeVisLab via Launchpad.

You need to repeat above steps only after a new installation.

You need to grant access to all folders macOS is asking.

This section shows how to handle MeVisLab on Linux:

Module Development on Linux

MeVisLab offers "Module Wizards", which are accessible via the file menu. They create the skeleton of ML and Inventor modules. The sources are created in a folder named by your module in the "Source" subdirectory of a MeVisLab package.

	Note
	Environment variable MLAB_ROOT is required to build C++ modules. MLAB_ROOT must point to InstallDirectory/Packages.

For compilation, CMake is used. See the CMake Manual for further information.

The MeVisLab SDK for Linux can also be installed and used within a Docker image.

Since MeVisLab for Linux was built for Ubuntu, it is best to use Ubuntu as the base image.

In addition MeVisLab always needs a running X server. Therefore we use xvfb for the installation. To be able to use MeVisLab after installation, you must also provide an X server. There are several ways to do this, including using xvfb.

We also use a multistage build to get the final image a bit smaller.
