Prebuilt index for C symbols? [message #208419]

Hi,

We have a large legacy codebase that we want to use with Eclipse CDT.
Maybe a million lines of code. We expect that the fast indexer will take
quite some time (haven't tried it yet.)

Can we index once and use that index as a starting point for multiple
users? In other words, each person runs their own copy of Eclipse CDT but
starts off with a pre-built index? After that it should be incremental
indexing. Also, the pre-built index may be slightly old compared to the
code in the workspace but we hope that it will still work.

I saw a document with the title, "Pre-built indexes in CDT 4.0". This talks
about PDOM and prebuilt indexes. It is not clear if the index mentioned in
this document is for the Help index or the regular index for a workspace. We
need the workspace index.

Thanks for any suggestions.

Not sure why you want extra work, GCC sources (4 mil lines) index within 20
seconds...

hi Sudhir,

Prebuilt indexes are intended for the use case where a vendor ships some
content (e.g. an SDK) which is immutable and merely referenced by a CDT
project. That is, they are not an end-user feature.

For the use-case where you wish to share an index between team mates, you
can use the Export -> C/C++ -> Team shared index feature.

This will create an index in a specified location relative to your project
that can be shared between team mates.

thanks,
Andrew

Thanks, Andrew. Just what I was looking for. However, I still could not
figure out how to use an already exported index. I don't see Import -> ...
Team Shared Index.

Could you say how a Team shared index can be imported?

Looks like that CDT is supposed to import the index automatically, when the project is initially imported to a workspace. To do so CDT looks at the default location .settings/cdt-index.zip, or wherever the index is recorded.

In my experience, the index is not imported properly:
