Description MedZed CLA 2011-07-12 09:02:15 EDT 
Build Identifier: 20110615-0604

I have a file with code that compiles just fine, but with the inclusion of Codan in Indigo, Eclipse is telling me I have a problem that I believe is incorrect.  When I use a type from a header file provided from a vendor, codan tells me it cannot resolve the type.  So if I use a variable of that type in an if() statement or as a return value from a function, codan barfs.

I'm attaching a screen shot and will put some code up if needed.

Reproducible: Always

Steps to Reproduce:
1. Declare a typedefed enum in a header
2. Make a varialbe of that type in a cpp file
3. Use the variable.  Codan barfs.

I can't reproduce this, can you provide some code? Also, try rebuilding the index (Right-click on project, Index, Rebuild).
Comment 3 MedZed CLA 2011-07-12 13:47:12 EDT 
Tried performing the Index rebuild, no help. 

I made a clean build with a very simple main and copy/pasted the offending enum.  I will put both files up here, simply make a new empty C++ project and put these two files in.  You should get the same error (I'll screencap as well).

That works for me too. Can you try the same simple project in a new workspace?

I created a whole brand new workspace and then copied the source files into a brand new project and it yielded the same result.

Could it be an issue with plug ins I may have?  Or perhaps CODAN settings?  Do you have something turned off in the Codan settings that is on by default?

The only plugin I've added on top of the C++ Linux Eclipse package is CUTE, a unit testing framework.
Comment 9 Marc-André Laperle CLA 2011-07-13 20:05:09 EDT 
It has to be some plug-in. I don't think we check for operator usage at all in the current checkers and I can't find that message pattern in codan.

You are correct, my mistake.  It is the plugin I am using for unit testing, CUTE... I'll email the authors with a link to this bug.

Thank you!
