transfer CDT project from linux to windows [message #758538]

I'm trying to create a CDT project in Windows or Linux and transfer the project to the other OS. I'm able to create a project and make it compile on either platform, but I can't get intellisense to work on the second platform and I receive errors and warnings in the IDE. The IDE isn't able to find the system include files no matter how I modify the project settings, which creates a bunches of undefined errors and missing header file warnings.

A project transferred from Windows to Linux gives an 'invalid project path' error with a path pointing to '<project_dir>/Debug/include'. A project transferred from Linux to Windows gives an 'error launching external scanner' warning which seems to indicate a 'discovery options' setting problem, but I receive this warning no matter how I change the settings.

The only method I've come up with that solves all of these problems is to create project files for Linux and Windows but that's not an ideal solution. I'd like to do it with different build configurations. Is this possible?

If you use different build configurations for Linux and Windows you can select a different toolchain for each platform.

I should have clarified; I am creating different build configurations. The projects build on both platforms, but the IDE does not have the proper paths on the second platform so intellisense doesn't work and it shows a bunch of errors and warnings. For example, for the project started on Linux and transferred to Windows, I added a build configuration that uses the VS compiler. The program builds on Windows, but the IDE shows a bunch of errors and warnings. Part of the issue seems to point to the 'Discovery Options'. Changes made to 'Discovery Options' seem to be ignored.

yes paths are not compatible...dooouuhh. Nothing but start project files from scratch.

Is new project files currently the only solution? Anyone know if this is something slated to be fixed?

An example project is attached. I created the project in Linux, then copied to Windows and created a build configuration called Debug-Win using MSVC. If you launch eclipse from the VS command prompt and open the project, the project should compile, but the IDE will show a bunch of errors.

To get code completion (intellisense) working you will need a different index for every build configuration. Open Project properties->C/C++ General->Indexer
Here you should select "Use active build configuration for the indexer" (at the bottom of the page). So when you switch from Linux to Windows build configuration (i.e. change the active build configuration) your index should be rebuild with the correct include paths and symbols.
