[cdt-dev] Problems with cross-platform CDT builds

["dmsubs" <dmsubs@xxxxxxxxxxxxx>]

Hi,

I have a bunch of plugins that extend CDT. 

I have defined a Product Configuration that builds my product. This builds
the entire product, including all the CDT and Eclipse components. This is
all working well on Windows and I have been building this way for a long
time.

I now want to build cross-platform (for Linux as well as Windows), so I have
added the eclipse-delta-pack (As described here:
http://aniefer.blogspot.com/2009/06/using-deltapack-in-eclipse-35.html). I
find that to get a successful build, I also have to add the cdt-master-6.0.2
in the same way. I then build my product and it all works as expected (I get
a product build for Windows and Linux, and both products work).

However, having added the delta packs (eclipse and cdt-master), when I  exit
Eclipse and restart it, I then get Java tooling errors(*). This only seems
to happen when I add cdt-master.

1. Am I going about cross-platform builds in the right way?
2. If so, any ideas on why my workspace keeps getting corrupted (If I import
the projects into a new workspace, all is OK again, unti I add the delta
packs...)
3. If not, how should I be doing cross-platform builds for CDT?

Any help appreciated!
