Install on Windows (from source, with CMAKE)

Prerequisites

• You must have a C++ compiler. We assume here ​Visual Studio 2008. The freely available ​Express Edition is fine.
• You must also download and install ​CMake 2.6.2 (.exe installer) or later.

Optional tools:

• For HTML document generation you need to install a recent version of Doxygen and Ghostscript.
• If you want to keep track of the latest development of LEMON or even contribute to it, you need the ​Mercurial distributed version control system. We strongly recommend to use ​TortoiseHg which provides a simple installer for Mercurial, a nice GUI and also an integration to the MS-Windows Explorer.

Obtaining the Source

• Either download and extract the following .zip files.
  • Latest stable release, version 1.0.1 (.zip)
  • Latest development snapshot (.zip)
• Or check out it with Mercurial. The development repository url is
  • http://lemon.cs.elte.hu/hg/lemon-main

Configure the CMAKE

The compilation must be done in a separate folder. We suggest to create a subfolder called build in the root of the source code repository.

Then start the CMake GUI and browse the source code and the build folders.

It is even better to start the "Visual Studio 2008 Command Prompt" from the start menu. Then, in the command prompt, step into the build folder and type

cmake-gui ..

Now click on the "Configure" button. Here choose

• either Visual Studio 9 2008 to create project files and an {{{.sln}} file usable from the Visual Studio IDE.
• or NMake Makefiles to create makefiles and compile from command line. In this case you must start cmake-gui from the "Visual Studio 2008 Command Prompt"

Then click again on "Configure" and finally on "Generate".

The configuration is done

Build and install

Finally - assuming you use a recent version of use Visual Studio - start a "Visual Studio Command Prompt" from the start menu. Then, in the command prompt, step into the extracted LEMON source directory and type in the following commands.

mkdir build
cd build
cmake -G "NMake Makefiles" ..
nmake
nmake install
