Kasper, not sure if this will help you, but I think the GLEW stuff was
added recently in V1.4.x and it seems to be still somewhat experimental.
May be to get you started you could switch to v1.3r1 from the repository
and try to embedd that version. V1.3.x should not contain the new GL
stuff.
Good luck
Carsten

Subject: [PyMOL] openGL/GLEW problems when embedding a PyMOL instance in
aPyQt4 widget
Dear pymol user and developer community
I am trying to embed a pymol2.PyMOL instance in a PyQt4 widget.
I am using the latest beta v1.4.1 (although it still says v1.4.0 in
layer0/Version.h, I assume you just forgot to update?). I use ubuntu on
a macbook.
I got it to display a black window inside a PyQt4 app, and I was even
able to produce som ugly little white square H atoms one time, plus som
menus only half visible. Yes, kind of strange.
The problem is openGL related. When typing pymol -v at the command line,
it tells me that my openGL version is pre 2.0, which is not true.
(Well, actually I wasn't entirely sure what precisely to look for in the
synaptic package manager, but libqt4-opengl is v4:4.7.0, python-opengl
is v3.0.1, python-qt4-gl is v4.7.4, freeglut3-dev is v2.6.0,
libglew1.5-dev is, well v1.5.2 glutg3-dev is 3.7-25)
Anyway, when I runt the following code (which may also contain the
source of the problem, I don't know):
class PymolQWidget(QGLWidget):
def __init__(self, parent=None):
QGLWidget.__init__(self, parent=parent)
self.pymolInstance = pymol2.PyMOL()
self.pymolInstance.start()
self.pymolInstance.cmd.load('<home-directory>/GUI/H2.pdb')'
self.pymolInstance.cmd.draw()
self.pymolInstance.cmd.show_as("sticks")
app = QtGui.QApplication(sys.argv)
pymolWidget = PymolQWidget()
pymolWidget.show()
sys.exit(app.exec_())
I get the following error message:
ShaderMgrInit-Error: Could not initialize GLEW:Missing GL version
which means that GLEW_OK!=err at line 145 in layer0/ShaderMgr.c, which
means the glew hasn't been initialized, which is as far as I was able to
get.
Needless to say, help would be greatly appreaciated.
Best,
