Hi William,
Upon looking more closely at the config.log
configure:11340: gcc -o conftest -g -O2 conftest.c -lGL 1>&5

configure: failed program was:
I see that ld could not find the GL libraries for some reason.
One thing to watch out for is the -g flag. This causes configure
errors with the latest Xcode. export CFLAGS and CXXFLAGS with -Os
before configuring.
export CFLAGS=-Os
export CXXFLAGS=-Os
If you need debug symbols, add -g back into platform.make after
configuration (to CFLAGS1 & CXXFLAGS1).
However, I have put this in my .profile. The location I have put is
usr/X11/lib . Is this the correct location?
# environment variables

export PATH=$PATH:$QTROOT/bin
export LD_LIBRARY_PATH=$VTK_LIB_DIR:$X11_LIB_DIR:$LD_LIBRARY_PATH
export DYLD_LIBRARY_PATH=$VTK_LIB_DIR:$X11_LIB_DIR:$DYLD_LIBRARY_PATH
Setting DYLD_LIBRARY_PATH is unnecessary on OSX. If you have to do it
for VTK, then the VTK build is broken. LD_LIBRARY_PATH is the linux
version of this and is not needed on OSX.
DYLD_LIBRARY_PATH only affects the finding of libraries at runtime,
not linking as in configure tests. And properly built libraries on
OSX should have the path built into them so they're found at runtime
without DYLD_LIBRARY_PATH. Though GRASS does use this as a neat trick
(as a side effect) to make the binaries relocatable.
Here is my configure command
./configure --with-cxx --prefix=/Applications/GRASS --enable-macosx-
app --with-x --with-cxx --with-opengl=aqua --without-readline --x-
includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib --with-
opengl-includes=/usr/X11R6/include
This is probably what is confusing the build - you set --with-
opengl=aqua, yet set the opengl includes and libs to X11. These
options can't be used together. Configure should force the includes
and libs based on the opengl value, but to be sure just use --with-
opengl, which defaults to X11, and you probably won't need the
includes/libs options.
Also note that you need to compile your own tcltk for X11, and set
those options for the GRASS configure. See the grass source osx
readme for details.
If I use the -with-opengl=x11 option, I get the following
configuration error
checking for location of OpenGL library...
checking for glBegin in -lGL... yes
checking for gluBeginCurve in -lGLU... yes
checking for glXCreatePbuffer... no
configure: error: *** Unable to locate .

configure:11340: gcc -o conftest -g -O2 conftest.c -lGL 1>&5
ld: library not found for -lGL
collect2: ld returned 1 exit status
This is strange - configure is inserting the X11 lib path for the
glBegin and gluBeginCurve tests, but not for the glXCreatePbuffer
test. Oh, I'm getting that also, but it's not keeping compilation
from working. This is just testing for the availability of pbuffers,
and GRASS has a fallback if that's not available.
So, your make error log doesn't have the needed info. You need to
look way back in the shell scrollback to see what the actual error
is. You may need to change your Terminal window settings to unlimited
scrollback.
