[cfe-dev] Problem building Clang in Eclipse

In that case, you would have to add the TableGen runs to the project as
custom build steps (I forget what they are called in Eclipse), so the generated
include files exist. Then point Eclipse to the correct directory, and it should
pick them up.


Hope that helps,
