Latest from hg on OSX

[John Swensen]

Has anyone got Octave to compile from the repository on OSX?  I keep  
getting OpenGL errors.  First I was getting a compile error that it  
couldn't find gl.h and glu.h.  So, I tried to add CXXFLAGS pointing to  
either the OSX Framework or /sw/include/mesa.  Either way, I get link  
errrors that it can't find all the opengl functions.  I tried to use  
LDFLAGS to point to either the OSX framework of /sw/lib/mesa, but  
can't get rid of the link error.  Any suggestions?

Hi John,

I'm running Octave with fltk/GL a few days now. It was a little bit tricky to
make the fltk/GL libs working, but now I have a nice FLTK window displaying graphs.

I downloaded two new source packages that we need on MacOSX -> fltk 1.1.9 and
ftgl 2.1.2. I compiled both from source against MacOSX's OpenGL libs.

For fltk I had to use the configure flags "--enable-shared --enable-quartz
--enable-gl" - I also tried other flags but without better results. I also
needed to remove the optimization flag "-ftree-vectorize" from my
C-,CPP-,CXXFLAGS - with this flag the fltk/GL engine doesn't work. No changes
necessary for LDFLAGS here. Once you have compiled fltk, make sure that in the
fltk/test directory the programs gl_overlay and glpuzzle display the graphs -
otherwise you won't have a chance to compile fltk/GL with Octave.

For ftgl I had to call "autoreconf" before "configure". I also needed to add
"-I/usr/X11R6/include" to my C-,CPP-,CXXFLAGS and "-framework OpenGL" to my
LDFLAGS. Then the steps configure, make, make install work very well.

Finally, I also added "-I/usr/X11R6/include" to my C-,CPP-,CXXFLAGS before
configuring the Octave sources and "-Wl,-framework -Wl,OpenGL" to the LDFLAGS. I
must say here that I haven't tried to configure the Octave sources without these
flags - I think I must check this out, ideally they should automatically be
found by the configure script on a Mac system.

Once compiled everything, I had and still have a problem resizing the figure
window, but I'm already in contact with Shai about that. I think there is still
a bug in the fltk sources but I currently cannot really figure out the problem -
so help is wanted ;)

But that's it already, all the sources are ok and can be compiled without error
as long as the dependencies do work pretty. The window appears and display of
the fltk/GL window is really great, thanks to Shai and Michael,

Regards,

   Thomas

I checked it, "-I/usr/X11R6/include" is necessary, "-Wl,-framework -Wl,OpenGL"
can be neglected for Octave.

And I forgot to say that I also needed to compile a new freetype2 because the
one that comes with OSX 10.4.9 is too old. Maybe this is not necessary with OSX
10.5.2. No FLAGS necessary for the configure step of freetype2, it compiles fine.

Thomas,

Might the current hg compile with fltk-aqua 1.1.7-1001? ... or is 1.1.9 required? ... perhaps fltk-aqua won't work either and I'll need fltk-x11?

If fltk-aqua 1.1.7-1001 is all that is needed, it should be a fairly simple task to get the current hg version working using Fink for the dependencies.

I don't know Ben, I'm always using the latest stable releases of source packages
which for fltk is 1.1.9. Don't know what is included in fltk-aqua? I would say
that if the test programs glpuzzle and gl_overlay display something then you
might have a good chance that the one as well as the other package can be taken.
I hope this helps,

Thanks for the response. At the moment I'm having trouble with Finks  
ftgl package. Once that is resolved I'll try build the current hg  
sources and report back.

There is no need for the duplication.  You should only need to add -I
options to CPPFLAGS (the preprocessor is the only thing that should
need -I, and CPPFLAGS are included in the rules for building object
files that are defined in Octave's Makeconf file).

Yes, ok, thanks.

I just found out that (I must once again correct my last email for the third
time now, sorry) we do need "-Wl,-framework -Wl,OpenGL" with LDFLAGS when
configuring the Octave sources because when linking gl-render.cc and others
together into liboctinterp.dylib it fails if not available. This framework is
currently not found automatically on a Mac platform, so I expect we could need a
test for that? If no volunteers then I'll try what I can do...

I have included a changeset which checks for Apple's OpenGL framework. But this
is not the only change that is needed, I also needed to add $(OPENGL_LIBS) into
src/Makefile.in line 277 OCTINTERP_LINK_DEPS. I am not sure if this is the right
place, but liboctinterp.dylib can be created now. If yes, then I can send
another changeset for this?

Hi,

I recently posted on the help-list as I had missed this thread...
I have been trying to build latest hg sources against fltk-aqua
from fink.

1) I am using the following flags:

./configure LDFLAGS="-L/sw/lib -framework OpenGL" CPPFLAGS="-I/sw/
include -FOpenGL" F77=gfortran FFLAGS="-ff2c" --prefix=/opt/octave/

2) I had to change
#include GL/gl.h    to     #include OpenGL/gl.h
and
#include GL/glu.h   to     #include OpenGL/glu.h
in gl-renderer.h

3) The build is completed but the resulting octave has problems
parsing some m-files. This was already mentioned in another thread,
a workaround seems to be adding some white space at the and of those
files

as for item 2) I haven't seen any other mention of this problem in  
this thread
so I was wondering if I have done something wrong there...

HTH,
c.

You're ahead of me. I'm presently unable to get Fink's fltk-aqua to build :-(

I plan ask seek some help form the Fink team when I have the time. Once I am able to build the new dependencies I might be of more help.

Perhaps you can give me a hand with my difficulty?

Are your running Leopard? ... and is you Mac PPC or Intel based?

In either event, did you have a problem building fltk-aqua?

Michael,

I think the fltk team have figured out a cross platform way of
including the OpenGL headers:

http://svn.easysw.com/public/fltk/fltk/tags/release-1.1.8/FL/gl.h
http://svn.easysw.com/public/fltk/fltk/tags/release-1.1.8/FL/glu.h

maybe we should adopt it?

I wonder where this OpenGL directory comes from or where it should be placed? I
searched my Mac for that OpenGL directory but couldn't find it. I have used
Apple's original GL framework, the headers are in /usr/X11R6/include/GL and the
libs can be accessed by '-framework OpenGL'. There are no changes necessary from
my point of view. Somebody please posts the output from

   bash~$ sudo find / -iname OpenGL

and

   bash~$ sudo find / -iname gl.h

Thanks,

Thanks Ben, not necessary - that's enough. I can see the same output that I can
also see on my Mac. But I still do not understand why it should be necessary to
#include <OpenGL/gl.h> instead of #include <GL/gl.h> on a Mac platform? I think
we need Carlo's output of

   bash~$ sudo find / -iname gl.h

I also tried to replace the #include <GL/gl.h> with #include <OpenGL/gl.h> and
the same for the glu.h. Next I tried the -FOpenGL flag with CPPFLAGS. All with
the same result: a compilation error. So, might there be some mismatch of GL
headers? BTW, I'm posting my output from my Intel 10.4.9 system (that, BTW, I
try to keep as clean as possible):

as far as I understand
-framework OpenGL and -FOpenGL
on darwin are shortcuts for
-L/System/Library/Frameworks/OpenGL.framework/Libraries
and
-I/System/Library/Frameworks/OpenGL.framework/Headers
and from the apple gcc manpage

"An example include looks like "#include <Framework/header.h>", where
  Framework denotes the name of the framework and header.h is found in
  the "PrivateHeaders" or "Headers" directory."

so I beleive that
#include <OpenGL/gl.h>
includes
-I/System/Library/Frameworks/OpenGL.framework/Headers/gl.h

and indeed FL/gl.h from fltk uses the same include clause:

#  ifdef __APPLE__
#    include <OpenGL/gl.h>
#  else
#    include <GL/gl.h>
#  endif

Ok for me, but then I vote for a configure-test which automatically sets up
"all" necessary Mac-specific compiler and linker options and ignores all the
other UNIX options.
My thought always has been to keep as much UNIX as possible for Mac too and to
not make the codes depend on too many platform specials, eg. like the Mac-only
-FOpenGL option and an #include <Framework/whatever.h> or similar.

Then, what about including FL/gl.h and FL/glu.h and rely on fltk to  
chose where to find OpenGL library and headers?
