[Kstars-devel] linker errors

[Jason Harris]

Hello,

I have worked around this problem, but I am not satisfied with my current 
solution.

My workaround is to add 
"../widgets/kstarsplotwidget.cpp ../widgets/timebox.cpp" to the SOURCES block 
in tools/Makefile.am.

This shouldn't be necessary, because libkstarswidgets.a is listed in the LDADD 
block, and it is my understanding that this file includes the object code for 
KStarsPlotWidget, TimeBox, and the rest of the widgets.  However, once I add 
the above files to the SOURCES block, I no longer get the linker errors.

Any ideas what is going on here?

So, as you see in my last commit log, we are now generating an actual kstars 
executable!  Now to make it actually run...
