Summary0015068: Eclipse cannot run Makefile (mingw)
DescriptionSince cmake 3.0 we cannot build from eclipse (tried Kepler and Luna). We uses the "eclipse cdt4 mingw"-generator on windows to create the projects. After import in eclipse there will be no reaction if we try to run the build or a special target of the Makefile.

The same workflow works with cmake 2.8.x flawlessly.

The build with cmake 3 works without problems if we use the terminal and run it manually with "mingw32-make".
Steps To Reproduce1. Take your project
2. Run cmake-gui and configure the project
3. Select "eclipse cdt4 mingw" generator
4. Import from "existing project" in eclipse
5. Select "build all" or double click on a special target
6. Eclipse does nothing

Expected:
Run the makefile
TagsNo tags attached.

I cannot reproduce this with CMake 3.0.0 or 2.8.12.2 and:

 Eclipse IDE for C/C++ Developers
 Version: Luna Release (4.4.0)

"Build All" always works the first time. After that it does nothing. If I remove build outputs by hand then "Build All" still does nothing, but if I refresh with "F5" then it works.

I observe no difference between CMake 2.8.12 and 3.0 versions.

Ok, we looked into it and found a hint for it.

If we create the project with cmake 3.0 it will create a .project with following "natures".

<natures>
  <nature>org.eclipse.cdt.make.core.makeNature</nature>
  <nature>org.eclipse.cdt.make.core.ScannerConfigNature</nature>
  <nature>org.eclipse.cdt.core.ccnature</nature>
</natures>

If we create the project with cmake 2.8 we have the following natures.

<natures>
   <nature>org.eclipse.cdt.core.ccnature</nature>
   <nature>org.eclipse.cdt.make.core.makeNature</nature>
   <nature>org.eclipse.cdt.make.core.ScannerConfigNature</nature>
   <nature>org.eclipse.cdt.core.cnature</nature>
</natures>

So if we copy the nature block from 2.8 .project file to 3.0 .project file we are able to run make with eclipse again.

Commit 51726cce64ee8bce1115f3c6d092b4ae6f43d714 seems to be the "problem". Since we added CXX in PROJECT only it won't create a cnature.
If we use CXX and C in PROJECT it will create a working .project. But of course cmake will search for a C compiler that we don't need.

We tried ECLIPSE_EXTRA_NATURES... but had no luck with it.

We created a new/empty C++ project with eclipse and looked into .project. Eclipse itself adds cnature and ccnature to it.

Attached a patch that will fix .project creation.

Re 0015068:0036865: Patch applied, thanks:

 Eclipse: Add org.eclipse.cdt.core.cnature to CXX projects

FYI, a patch will get broader visibility on the developer mailing list. See CONTRIBUTING.rst.

I've queued this for 3.1.1 since it is a regression fix.
