[Kst] CFITSIO Problem

[Nicholas Chapman]

Hi, no, I haven't solved the problem yet.  After talking to someone
here and spending some time searching on the internet, my best guess
is that it is a problem with linking a c library (cfitsio) into a c++
program (kst).  That would explain why the linker complains about an
undefined symbol _ffclos, when cfitsio defines ffclos.  See the
following for a description on how to link c programs into c++:
http://stackoverflow.com/questions/4598308/how-do-i-compile-and-link-c-code-with-compiled-c-code

I've tried the solutions suggested there in just about every possible
place (such as wrapping the #include statement directly in my plugin,
then editing longnam.h (called by fitsio.h) and fitsio.h in various
ways with 'extern' commands.)  None of these have worked.

Peter, I tried adding the command you suggested to the CMake Wizard
dialog, but I get the following error:
CMake Error: The source directory
"/Users/chapman/data1/Applications/ksttmp/--Dkst_3rdparty_build=1"
does not exist.

I am building the code in a separate directory named ksttmp, so
perhaps I just need to modify the path appropriately (from ../kst to
something else), but it isn't obvious to me what that should be.

One option I haven't tried yet is to re-write my plugin to use ccfits
instead of cfitsio.  ccfits is a c++ version of cfitsio.
