Eclipse CDT4 Generator
Starting with version 2.6.0 CMake includes an Eclipse CDT 4.0 generator (not released yet, but already in cvs). It works together with the Makefile generators available now (i.e. "Unix Makefiles", "MinGW Makefiles", "MSYS Makefiles", and maybe "NMake Makefiles"). With this generator it is possible to create a set of .project/.cproject files that can be imported in Eclipse as an "Existing Eclipse project".
Note that CMake 2.4.x users may follow instructions provided here CMake:Eclipse in order to setup an Eclipse+CMake usage manually.
Using Eclipse CDT4 Generator
Using the Eclipse CDT4 generator is not different as using another CMake generator, it works for in-source and out-of-source builds. In this example I assume the source tree of my project is /home/eric/certi_src
- Create a build directory and goes there
mkdir /home/eric/certi_build cd /home/eric/certi_build
- Launch CMake
cmake -G"Eclipse CDT4 - Unix Makefiles" ../certi_src
After that you will find two Eclipse file in your build tree:
- Import the created project file into Eclipse:
- Launch eclipse
- Import project using Menu File->Import
- Select Existing projects into workspace:
- Browse where your build tree is and select the root build tree directory
- You get a fully functional eclipse project
Using Eclipse CDT4 Generator with version control systems
There is a limitation of the CMake CDT4 Eclipse generator when your source tree is handled by a versioning system (like CVS, Subversion or other) you may read the referred discussions in the links below.
A maybe acceptable solution is to have 2 projects:
- one for version management This one may be obtained by a normal checkout using new project from CVS
- one for building, resulting from the imported CMake generated project which is obtained by the previously described procedure
You will find a screen cast describing how to it here: File:CMakeEclipseCDT4andCVS-2.ogg
Discussion about Eclipse CDT4 Generator limitations
If you would like to monitor the changes to the EclipseCDT4 support, you can view the following links which contain the cvs history log for changes to the two main files:
Eclipse assumes project files (i.e. .project and .cproject) must be at the root of the project tree and a project may be handled by a versioning system (CVS, SVN, ...) iff the root project tree is.
This assumption clashes with the fact that CMake generated files should stay in the build tree whereas source files (which are usually those handled by a versioning system) reside in the source tree.
There has been a fair amount of discussion regarding this problem of the Eclipse CDT4 Generator:
- Trouble with CMake + Eclipse + SVN/CVS
- *Updated* Eclipse CDT4 CMake Generator - Pre-Alpha version
- Partially Shared project using Eclipse CDT (cdt-dev ML)
