Re: [cdt-dev] The Indexer only wants to use the default system headers

["Anne van Rossum" <anne@xxxxxxxxxxx>]

Dear Dmitry,

Thanks for your response, I managed to get it working! Having somebody like you as backup really helps.

FYI. The problem was not that the directories didn't show up at "Paths and Symbols", but that they seem to be in the wrong order. So, the problem is not that the indexer doesn't find them, but that it first finds the system files and hence redirects to the wrong files. Now, I manually added the directories again, so they appear on top of the list over there, I used the "Full Indexer" and included also files that weren't built or included (first option). And now <string.h> goes indeed to the appropriate file. 

I think it might be considered a small bug that even though my $PATH environmental variable starts with the custom "/opt/arm-2008q1/arm-none-eabi/include" directory, the Indexer first searches in the "/usr/include" directory. Am I correct that this might be considered a bug? Or is this bug solved in a later version (I use Eclipse 3.2.2)?

Kind regards,

Anne

Try to add /opt/arm-2008q1/arm-none-eabi/include to the list of
include directories of your project (Properties->C++ General->Paths
and Symbols) and rebuild the index.
Also, you can try to use Properties->C++ Build->Discovery
Options->Discovery Profile options->Load Build output from file.
Using it, you can use the build log to be parsed and all the include
paths and symbols to be added to the project automatically.
