O2_GENERATE_DICTIONARY problem when Headers are not set explicitely

[sawenzel]

I ran into the following problem:

a) I do not set HEADERS explicitely in my cmake b) I set LINKDEF to some LinkDef.h

Since HEADERS are not set, O2_GENERATE_LIBRARY will search for HEADERS itself and picks up LinkDef.h. This leads to errors with rootcling because "LinkDef.h" will appear twice.

I think we need to protect against this in some way. Possibly just checking if the LINKDEF file is also present in the HEADERS list.

You are correct. I'll have a look.

Is this done?

[Barthelemy]

no. I will move it to JIRA where I will be able to see it and organize it with the rest of my work. How can I close this one ? There is no close button.

@Barthelemy: I think the issue should stay open here in parallel. Otherwise, it is hard to track progress and know when it was done ...

[Barthelemy]

@sawenzel I understand your point. At the same time, I fear that it will quickly become unmanageable. I will keep it opened for now but would like to rediscuss it with you after Christmas, maybe around a coffee.

[sawenzel]

Agreed.
