[GRASS-dev] trying to compile wxPython NVIZ

[Michael Barton]

I just managed to compile GRASS on the Mac OS X (10.5.4) without x11  
and with aqua tcltk 8.5.1. It actually works and looks pretty good.  
NVIZ does not work. No TclTk error messages (this is a difficulty with  
nviz; it traps all errors so you can't see what is wrong). However,  
because this is native aqua TclTk, it did give an Apple error message  
that I'll copy in below. It may be helpful if someone want's to debug  
it (I've added Paul to the cc list because of this).

You can see some quick screenshots of the GUI here <http://www.public.asu.edu/~cmbarton/files/grass_screenshots/grass_osx_aqua/ 
 >. It looks surprisingly good. To get TclTk 8.5 aqua to compile and  
run, I had to do the following...

make distclean

export TCLTK_INTERNAL=
export TCLTKVER="8.5"

./configure --with-freetype --with-freetype-includes="/Library/ 
Frameworks/FreeType.framework/unix/include/freetype2 /Library/ 
Frameworks/FreeType.framework/unix/include" --with-freetype-libs=/ 
Library/Frameworks/FreeType.framework/unix/lib --with-gdal=/Library/ 
Frameworks/GDAL.framework/Programs/gdal-config --with-proj --with-proj- 
includes=/Library/Frameworks/PROJ.framework/unix/include --with-proj-

includes=/Library/Frameworks/UnixImageIO.framework/unix/include --with-

tiff-includes=/Library/Frameworks/UnixImageIO.framework/unix/include -- 
with-tiff-libs=/Library/Frameworks/UnixImageIO.framework/unix/lib -- 
without-postgres --without-mysql --with-odbc --with-sqlite --with- 
sqlite-libs=/Library/Frameworks/SQLite3.framework/unix/lib --with- 
sqlite-includes=/Library/Frameworks/SQLite3.framework/unix/include -- 
with-fftw-includes=/Library/Frameworks/FFTW3.framework/unix/include -- 
with-fftw-libs=/Library/Frameworks/FFTW3.framework/unix/lib --without- 
x --with-cxx --with-opengl=aqua --without-readline --prefix=/ 
Applications/GRASS --enable-macosx-app --with-python --with-wxwidgets=/ 
usr/local/lib/wxPython-unicode-2.8.7.1/bin/wx-config --with-tcltk- 
includes="/Library/Frameworks/Tcl.framework/Headers /Library/ 
Frameworks/Tk.framework/Headers /Library/Frameworks/Tk.framework/ 
PrivateHeaders"

sudo make install

THEN, I had to find a copy of wish.app, show contents, and extract a  
copy of Wish from inside Wish.app/Contents/MacOS/.

NEXT, I had to rename Wish to wish8.5 and put it into /Applications/ 
Grass/GRASS-7.0.app/Contents/MacOS/bin of the binary GRASS-7.0.ap that  
I'd just made.

After that GRASS launches fine in Mac TclTk aqua

I assume that this last part could go into the build instructions.

Perhaps this will help move all of GRASS Mac to native aqua as the  
wxPython GUI continues to get refined. If the nviz issues with aqua  
TclTk could be solved, the Mac version could dispense with x11  
completely--and would still have a terminal for running bash and other  
command line things.

When I compiled, I got a number of togl warnings, but no obvious  
errors. So perhaps it can be made to run in 8.5.1 where it was  
problematic in 8.4.
