This tutorial shows how to set up and use Eclipse for compiling and running BRL-CAD.  BRL-CAD uses the CMake build system so it can generate project files for a number of different development environments.  Here we show you how to create a project using the Eclipse CDT4 generator.
+
I will show you how to do that using the Eclipse CDT4 generator, which isn't different than using any other CMake generator. It works for in-source and out-of-source builds.
  
−
Note that you can [[Compiling/Eclipse/Manually|manually set up an Eclipse project]] for BRL-CAD, though there are several substantial differences in the result.
+
At first we need to run CMake, and set ”Where is the source code” and “Where to build the binaries”, but before thatyou have to be sure that you have a ''CMakeLists.txt'' file in the src directory .  Your project name should be different from your executable name and different from your build folder name. Otherwise, Eclipse will NOT pick up your executable as you build them. Our second work is that to select the generator(the window ''cmake-gui'' appears when you click '''Generate'''), in our case – Eclipse.

For Eclipse, it is important that the build directory not to be a subdirectory of the source directory due to a CMake limitation.

Next, we could build everything, but here we build pieces of the project with the ''benchmark'' and ''mged'' targets. First, the BRL-CAD benchmark:
+
And now I will build project with targets ''benchmark'' and ''mged''. At first – benchmark:  
 
''Project/Make Target/Build...'', then select target:''benchmark''(location ''bench'') and click '''Build'''
 
''Project/Make Target/Build...'', then select target:''benchmark''(location ''bench'') and click '''Build'''
