Does someone have a fix for false warnings from eclipse ide with C++ quantlib projects?

[Michael Barrow-2]

Hi all,

I'm a long time stalker first time poster. False compiler warnings and the unresolved symbols (CDT only) with eclipse IDE when one includes quantlib.hpp seem to be well known. However I've not been able to fix this in Eclipse. Does anyone have some 'gold' settings (I'm using eclipse Indigo on Ubuntu 12.10) that they can share? I've tried adding the quantlib source tree to my project and re-indexing (from eclipse) to no avail.

It is quite difficult picking through the noise from compilation and code completion would be a God send.

Best regards and Merry Christmas,

Mike

Hi Michael,
    I'm afraid I'm not familiar with the problem.  What kind of
warnings are you getting? Is it something that we can fix in the code?

Later,
    Luigi

Hi Luigi,

This fellow has reported similar problems on his blog (at the very end as a note) http://quantcodetips.blogspot.co.uk/2012/02/setup-quantlib-under-windows-using.html 

When compiling the test suite, warnings are unresolved symbol errors and some warnings involving the style of virtual function definitions (there are around 200+)

I've not been able to root cause, but it may be possible to resolve this in QuantLib code as certain styles trip up the eclipse CDT indexer, however I can neither confirm this is what is happening or give an estimate of the work involved. 

I've attached a trivial example showing eclipse's inability to index the Quantlib includes despite its ability to successfully compile and run against them.

If anyone is interested in a quick workaround, I've found that if you simply paste quantlib.hpp at the top of a cpp file, the eclipse Codan/CDT indexer seems to pick up on symbols correctly for that source file.

Any other pattern (copying quantlib.hpp to a project folder & referencing that for example) just does not work. Finger is squarely pointed at the eclipse guys on this one IMO.
