split from #147

I thought that buiding (py)gtkgl on osx would be a good stepping stone for eventually getting it to work/build on win32...

All these instructions are from within a gtk-osx jhbuild shell (tested with xcode 3.2 on osx 10.5):

gtkglext

  • we use the git version to get osx support (no public releases for over 5 years - yikes!):
git clone git://git.gnome.org/gtkglext
cd gtkglext
  • then we ignore the documentation which is out of date, wrong and completely missing when it comes to building on osx, and we configure the build with the totally undocumented (but supported) quartz gdk backend, but only after defining the magic compiler variables that prevent libtool from barfing at us with:
libtool: compile: unable to infer tagged configuration
libtool: compile: specify a tag with `--tag'
make[4]: *** [gdkglquery-quartz.lo] Error 1
make[3]: *** [all-recursive] Error 1
make[2]: *** [all] Error 2
make[1]: *** [all-recursive] Error 1

Some good info on libtool issues can be found here.
[[BR]]
So then end up with:

export CXX=/usr/bin/c++-4.2
export CC=/usr/bin/gcc-4.2 
export OBJC=/usr/bin/gcc-4.2 
gtkdocize
autoreconf -is
./configure --prefix ${JHBUILD_PREFIX} \
            --libdir ${JHBUILD_PREFIX}/lib \
            --with-gdktarget=quartz \
            --build=i386-darwin
make
make install

(may sound simple but this was anything but)

[[BR]]

pygtkglext
The real problems start with pygtkglext.
There are two ways of building it: distutils and autotools based, none of which work.
Again, we use the more up to date version from git (not that the 1.1 makes any difference..):

git clone git://git.gnome.org/pygtkglext
cd pygtkglext

-pygtkglext distutils*

  • python ./setup.py install --prefix=$JHBUILD_PREFIX fails with:
TypeError: pkgc_version_check() takes exactly 2 arguments (3 given)

we remove the broken pkgconfig check by commenting out the two lines:

if not pkgc_version_check('pygtk-2.0', 'PyGTK', PYGTK_REQUIRED_VERSION):
    raise SystemExit, "Aborting"

(you should really check that you do have pygtk-2.0 correctly installed at this point and that you have the pkgconfig file it would normally check against, ie: $JHBUILD_PREFIX/lib/pkgconfig/pygtk-2.0.pc)

  • then we get this other error:
Traceback (most recent call last):
  File "./setup.py", line 117, in <module>
    override='gtk/gdkgl/gdkglext.override')
  File "./gtk/inst/lib/python2.7/site-packages/gtk-2.0/dsextras.py", line 495, in __init__
    py_ssize_t_clean))
  File "./gtk/inst/lib/python2.7/site-packages/gtk-2.0/dsextras.py", line 399, in __new__
    codegen_error_message))
NameError: 'Template' is not defined

Which means that it doesn't find codegen... (really not obvious). So we tell it where to find it:

PYTHONPATH=$JHBUILD_PREFIX/share/pygobject/2.0/:$PYTHONPATH python2.7 ./setup.py install \
        --prefix=$JHBUILD_PREFIX
  • then we get this error:
gtk/gdkgl/gdkglmodule.c: In function 'init_gdkgl':
gtk/gdkgl/gdkglmodule.c:86: error: 'gdkglext_major_version' undeclared (first use in this function)
gtk/gdkgl/gdkglmodule.c:86: error: (Each undeclared identifier is reported only once
gtk/gdkgl/gdkglmodule.c:86: error: for each function it appears in.)
gtk/gdkgl/gdkglmodule.c:87: error: 'gdkglext_minor_version' undeclared (first use in this function)
gtk/gdkgl/gdkglmodule.c:88: error: 'gdkglext_micro_version' undeclared (first use in this function)
error: command '/usr/bin/gcc-4.2' failed with exit status 1

And those values only get mentioned in the gdkglversion section of gtkglext/docs/reference/gtkglext/gtkglext-sections.txt, and in gtkglext/gdk/gdkglversion.c we can find functions that look like they would almost match: gdk_gl_get_major_version, gdk_gl_get_minor_version and gdk_gl_get_micro_version.
So we replace the code in gtk/gdkgl/gdkglmodule.c like so:

    tuple = Py_BuildValue("(iii)",
                          gdk_gl_get_major_version(),   /* gdkglext_major_version */
                          gdk_gl_get_minor_version(),   /* gdkglext_minor_version */
                          gdk_gl_get_micro_version());  /* gdkglext_micro_version */
  • then we get this new build error:
In file included from ./gtk/inst/include/gtk-2.0/gtk/gtk.h:234,
                 from ./gtk/inst/include/pygtk-2.0/pygtk/pygtk.h:8,
                 from gtk/gdkgl/gdkglext.override:26:
./gtk/inst/include/gtk-2.0/gtk/gtkitemfactory.h:47: warning: function declaration isn't a prototype
gtk/gdkgl/gdkglext.override:36:19: error: GL/gl.h: No such file or directory
(...)

Which can be fixed by adding /usr/X11/include to the include path in setup.py:

GLOBAL_INC.append("/usr/X11/include")
  • but then we get another error:
gtk/gdkgl/gdkglext.override: In function '_wrap_gdk_gl_config_new':
gtk/gdkgl/gdkglext.override:130: error: 'GDK_TYPE_GL_CONFIG_MODE' undeclared (first use in this function)
gtk/gdkgl/gdkglext.override:130: error: (Each undeclared identifier is reported only once
gtk/gdkgl/gdkglext.override:130: error: for each function it appears in.)

I give up...

-pygtkglext autotools*
It's a mess - don't go there.
Missing macros, out of date docs, etc.

OSX is really unpleasant to deal with, GL should be the last of our worries. Not going to bother.

Another attempt using autotools:
gtkglext:

  • fix gtkglext's configure.ac to avoid this error:
configure.ac:58: error: 'AM_CONFIG_HEADER': this macro is obsolete.
    You should use the 'AC_CONFIG_HEADERS' macro instead.

by doing this:

sed -i -e 's/AM_CONFIG_HEADER/AC_CONFIG_HEADERS/g' configure.ac
  • generate build config:
autoreconf -fiv
./configure --prefix=${JHBUILD_PREFIX}
  • fix gdk/quartz/Makefile (or tell configure using --with-tags=CC ?):
sed -i -e 's+/libtool$+/libtool --tag=CC+g' gdk/quartz/Makefile
  • build:
make

And ignore errors in examples (missing pangoft2) - or remove "examples" from top-level Makefile

  • then we can finally install:
make install

Notes: on 10.6.x, we were getting these errors:

Undefined symbols:
  "_objc_msgSend", referenced from:
    (... lots of places ...)

This was solved by adding:

  • "-framework Foundation -framework OpenGL" on 10.5
  • "-framework Cocoa -framework OpenGL -framework Carbon" on 10.6
    to GL_LIBS in the gdk/quartz/Makefile (there probably is a better/more correct way, but this worked).
    (note: you may need to make clean && make)

-pygtkglext* from git:

  • fix pygtkglext's configure.ac:
sed -i -e 's/AM_CONFIG_HEADER/AC_CONFIG_HEADERS/g' configure.ac
  • fix tuple as per distutils instructions
  • fix GL include path by patching it in the Makefile..
  • then remove lots of things that don't build..
  • then you install and find you can't load it:
$ python
>>> from ctypes import *
>>> x=cdll.LoadLibrary("/Users/MacAdmin/gtk/inst/lib/python2.7/site-packages/gtk-2.0/gtk/gdkgl/_gdkgl.so")

    self._handle = _dlopen(self._name, mode)

$ nm /Users/MacAdmin/gtk/inst/lib/libgdkglext-quartz-1.0.0.dylib | grep __gdk_gl_context_destroy

If at first you don't succeed, try again.. and again, and again.
[[BR]]

Eventually, got it to build and load, use the attached files to replace the ones shipped with pygtkglext (in gtk/gdkgl). We remove lots of stuff that does not build (either because pygtkglext has not kept up with gtkglext or because they are missing from the quartz backend).

The resulting shared object loads, though we are missing a bunch of constants so we still have to patch a few places to get it to run..

(hack): rather than hardcoding each value that is missing when we hit a problem, this hacks all the values from gdkgltokens directly into the python code:

    sed 's+  GDK_GL_++g' | sed 's+,.*++g' | sed 's+\/\*.*++g' \
    >> ~/pygtkglext/gtk/gdkgl/__init__.py

It looks like the osx client logs GL extensions as unavailable. Attached client logs from starting a session.

What makes you think it is not available?
Looks ok from what I am seeing, no warnings and no errors.

With r3832, we now include all the accelerator functions (optional but useful), so these warnings should now be all gone:

Unable to load ArrayDatatype accelerator from OpenGL_accelerate
Unable to load converters accelerators (wrapper, arraydatatype) from OpenGL_accelerate
Unable to load arrayhelpers accelerator from OpenGL_accelerate
Unable to load nones_formathandler accelerator from OpenGL_accelerate
Unable to load numpy_formathandler accelerator from OpenGL_accelerate

If they are still present in newer builds, please post the output of:

Xpra.app/Contents/Helpers/Python -c \
   "from OpenGL_accelerate.arraydatatype import AsArrayTypedSizeChecked;
from OpenGL_accelerate.wrapper import returnPyArgumentIndex;
from OpenGL_accelerate.arraydatatype import (AsArrayOfType,AsArrayTyped,AsArrayTypedSize)"

(should be empty)

(btw, please don't use RTF unless absolutely necessary, text/plain is better as it is machine parseable, grepable, etc)

Sorry, I thought the unavailable extensions was NOT expected.

With osx 0.10 r3830 I am still getting a lot of GL Extension GL_blahBlah unavailable messages on start, but I am not getting any of the Unable to load blahBlah from OpenGL_accelerate ... and just to be sure I ran the command you suggested and did indeed get no output.

(and my Mac's TextEdit, for some idiotic reason, doesn't give .txt as a save format option, at least not a readily available option... didn't realize it was a hassle, a spot of extra work and I can make .txt in future)

So, was GL enabled or not?
What does session-info show? Any GL windows? GL renderer info?

FYI: you can create plain text files without trouble with just "cat > file.txt" when pasting log samples.

Without a tray, I'm not aware of a way to get the session info, so I'm not sure how else to check for GL enabling- except from those logs that show when the client is started from the command line.

Many of the extensions show as unavailable, but there does seem to be an OpenGL module available, namely: 2013-07-11 19:31:26,972 OpenGL Version: 2.1 APPLE

Hah, yes, until I restore the tray here are 2 ways:

  • looking in the client log:
grep make_new_backing client-debug.log
  • using xpra info (gl has more limited csc):
xpra info | grep -i csc

Which should look like this with OpenGL:

client.encoding.csc_modes=('YUV420P', 'YUV422P', 'YUV444P', 'BGRA', 'BGRX')
window[1].client.csc_modes=('YUV420P', 'YUV422P', 'YUV444P')

Whereas a regular window backing will also support BGR modes.

I see from the client logs in #379 that opengl is enabled on a real mac and works ok:

pygdkglext version=(1, 1, 0)
pygdkglext OpenGL version=(1, 0)
using display mode: ['SINGLE']
OpenGL_accelerate module loaded
Using accelerated ArrayDatatype
OpenGL Version: 2.1 APPLE
(...)
vendor: Apple Computer, Inc.
renderer: Apple Software Renderer
shading language version: 1.20
GLU extensions: 
GLU version: 1.3 MacOSX
(...)
Texture size GL_MAX_RECTANGLE_TEXTURE_SIZE_ARB=16384
(...)

Then for each window:

GL Pixmap backing size: 499 x 316, drawable=\
    <gtk.gdk.GLWindowImplQuartz object at 0x17596328 (GdkGLWindowImplQuartz at 0xa13c80)>
(...)
present_fbo() drawable=\
    <gtk.gdk.GLWindowImplQuartz object at 0x17596490 (GdkGLWindowImplQuartz at 0xa13c80)>

For building on 10.6... (hang on to your seats, it's even uglier than above - yes it's possible)

How I ended up doing it:

  • Note the small changes specific to 10.6 in comment:5 (changes to -framework list)
  • use the distutils route to get the shared object files to be linked properly (otherwise all the symbols got missing when using autoconf ..)
  • when the install step fails because of the really old version requirements... use rsync to install "by hand":
rsync -rpvlgto \
   build/lib.macosx-10.6-i386-2.7/gtk/* \
   ~/gtk/inst/lib/python2.7/site-packages/gtk-2.0/gtk/

And then we get a runtime crash:

(gdb) bt
#0  0x00487f57 in g_type_name () from /Users/spikesdev/gtk/inst/lib/libgobject-2.0.0.dylib
#1  0x006d942d in pyg_flags_add () from /Users/spikesdev/gtk/inst/lib/python2.7/site-packages/gobject/_gobject.so
#2  0x01fd7080 in pygdkglext_add_constants () from /Users/spikesdev/gtk/inst/lib/python2.7/site-packages/gtk-2.0/gtk/gdkgl/_gdkgl.so
#3  0x01fd5829 in init_gdkgl () at gtk/gdkgl/gdkglmodule.c:109
#4  0x000e154e in _PyImport_LoadDynamicModule (name=0x2814600 "gtk.gdkgl._gdkgl",

Ugly, ugly.
We can comment out the call to add_constants and re-add the constants to the module using the hack from comment:10
Build again, install again.

Then it seems to work in as much as the module loads without crashing.

Update: this is being moved to #533, which now includes all-in-one patches for both packages. See also #563#comment:14

correct patch, which allows gtkgl to load on all machines and not just the one I build on

somehow this got missed because the file isn't tracked by git, ugly way of fixing things
