Subprojects give me grief when using cmake [message #899936]

Hello,

I use cmake to create my projects. My build directory is "out of source". Cmake creates three "resources" in my project:
[Source Directory]: this is where my source is
[Subprojects]: I have no idea what this is for, but it also holds my source
[Targets]: Again, I have no idea what this is for.

Question: How do I tell Eclipse/CDT to never open a supposed "source file" from within the "Subprojects" resource?

Sometimes Eclipse's extremely useful F3 key takes me to a file in the bogus resource. Worse, I often do not realize what had happened and start editing them and eventually screw myself over.

Thank you!

Chris

Select the Subprojects folder in the Project Explorer. Right click to open the context menu. There select Properties. Go to Resources and enable the attribute "Derived".
Eclipse will then treat this folder as "automatically generated source code" and will ignore it for search results.

Axel,

Thank you for this tip. I have been using it for the past couple weeks. I like that I can mark a project "derived" and signal that it should not be used for source code editing. I do not use Eclipse's 'search' feature, but I do believe you when you say "derived" projects are excluded from search results.

An eclipse feature that I use (and love) is F3 also known as "Open Declaration". Sometimes (I'd say 20% of the time) using F3 brings me to source code in a "derived" project. I generally do not notice when this happens. However, if I attempt to edit the source code, Eclipse CDT interrupts me with a modal dialog: 'Are you sure you want to edit source code in a "derived" project?'

Question: Can I command Eclipse/CDT to never direct me to "derived" projects when performing an F3/Open_Declaration?

Thank you again for your help,

Chris

Derived folders are normally excluded from being indexed and thus F3 should ignore them. I guess you need to rebuild your index (context menu of Project and then Index->..) to get rid of them.

Unfortunately this is not the case. I filed a bug report here:

In Project Properties->C/C++ General->Paths and Symbols you can define the Source location (default is the whole project but you can exclude subfolders). The indexer will only have a look at these folders.

Axel,

This seems to work! I cannot tell you how happy this makes me! Thank you!

I filed a cmake bug to encourage them to change this setting:

Thank you!
