Cevelop breaks Eclipse Neon configuration on migration #5

Closed dvorka closed 7 years ago

dvorka commented 7 years ago

Expected Behavior

I wanted to give Cevelop a try and attempted to open existing Eclipse Neon 2 project. I expected project to be successfully built and continue to develop w/ Cevelop.

Actual Behavior

Cevelop changed (removed part of) existing configuration - diff:

This broke existing build + through the project's configuration UI I'm getting the following error:

Cevelop/Project Properties/C/C++ Build

The more we know about your setup, the easier it will be for us to reproduce the problem.

BTW, I was able to successfully workaround the problem by deleting existing configuration (.project, .cproject and .settings) and I can enjoy Cevelop.

Hi Martin, thanks for reporting this. I think this happened because Cevelop does not come with CDT's Cross GCC support. I's an optional feature, but we didn't realize that its absence would break existing projects. So for the next release, we're going to include it by default, just like CDT.

dvorka commented 7 years ago

That would be great - I think that I became Cevelop over the weekend user :smiley:

misto commented 7 years ago

The newer Cevelop releases now include Cross GCC support.
