[GRASS-dev] 7.svn fails to build from source

[William Kyngesburye]

I updated the makefile to strip 64bit flags on OSX.  But I found  
another problem: it uses WXWIDGETSLIB for linking (it's only  
wxwidgets, not wxpython), and it includes universal flags,  
independently of however GRASS is configured.

I've been compiling GRASS 7 with -arch i386 -arch x86_64, skipping  
PPC, and I'm sure many people will just opt for a "native" build (i386  
or ppc).  So, the sources compile i386 (stripped of x86_64), but then  
tries to link i386 + ppc because of WXWIDGETSLIB.

Nothing I can do about this, it's really a wxwidgets config bug.  arch  
flags should not be a part of link flags, and the arch flags don't  
even appear in WXWIDGETSCXXFLAGS or WXWIDGETSCPPFLAGS where they  
should be.

The workaround is to make sure to configure GRASS universal.

WXWIDGETSLIB doesn't affect the wxpython modules, nviz and vdigit,  
wince they use a setup.py (where I have WXWIDGETSLIB ignored for OSX,  
though I'm not sure this is the right way).

Maybe I can strip the arch flags out of WXWIDGETSLIB...
