I have installed Eclipse Indigo for C/C++ Linux developers on Ubuntu 10.04 x86.
When I use common predefined macro __BASE_FILE__ Eclipse says Symbol '__BASE_FILE__' could not be resolved, but compilation is OK. I have to use it so often in my code and Eclipse fills my screen with red lines and bug icons :)
How can I fix this?
See Question&Answers more detail:os
Not sure if this addresses your specific problem, but I also had semantic errors. They just came out of the blue after having a working project.
Anyway, I fixed it with a single option in workspace settings by setting: "Build configuration for indexer: Use active build configuration"
The other option was "Use the build configuration specified in the project's indexer settings" and this is the one that wasn't working. I think it may have been corrupted after an eclipse crash.
