[Kst] CFITSIO Problem

[Nicolas Brisset]

Hi Nicholas,

have you been able to sort out your issue? Our cmake guru (Peter) is probably on holidays, otherwise he'd have sent an answer the day you asked :-)
To make sure what command is run there is a silent option somewhere which can be deactivated. I would suggest you try this to make sure the right flags are passed at link time.
Otherwise it could be a Mac-specific issue maybe? Are you using the same compiler for Kst as for the CFITSIO lib?
I guess you've checked the cmake flags against another datasource using an external library?

Sorry that I can't be more specific, but without the code and with only my limited knowledge of cmake and Mac OS X development I can't do much more right now.
I hope it will still help you.

Cheers,

Nicolas
