According to http://wiki.flightgear.org/index.php/Plib there should be no dependency on PLIP windowing library (pw). I found that FG/src/GUI/layout_test.cxx uses plip/pw.h. Since I am building flighgear on a 64-bit mac layout_test.cxx does not compile. This is a consequence from the fact that Carbon is not available as a 64-bit library, and PLIB only supports Carbon for Mac OS X. I am using the 64-bit enabled Cocoa which, luckily for me, is supported by OSG.

I suggest that layout_test is rewritten and the PLIB pw dependency is removed, and thus making the statement regarding PLIB in http://wiki.flightgear.org/index.php/Plib correct. Another option is to change the wiki page.

Also, I think that test programs should in general be created by issuing 'make check'. I have attached a trivial patch that moves compilation of layout_test as a part of 'make check' instead of a simple 'make'. It does not resolve the issue with PLIB pw dependence but allows mac 64-bit users to compile the essential components of the flightgear source.

Can someone please commit the patch to the CVS?


Cheers,

Jari
