[PyOpenGL-Users] PyOpgnGL-3.0.1a2 MSVCR71.dll not found

[David L. P. <pa...@gm...>]

I am attempting to install PyOpenGL-3.0.1b2 on a Win7 system with Python 2.6
installed. I receive an error that msvcr71.dll was not found upon start of
the PyOpenGL install exe.

I have found online suggestions to download msvcr71.dll from various sites
and then to copy that dll into the win system directory. For obvious
reasons, I am unsatisfied with this solution and haven't attempted it.

Does any else have a work around?

Hmm, that's a pain.  If I'm reading correctly, there's no VC 2003 (7.1)
redistributable download on microsoft.com.  So there's no official way
to redistribute it?  That doesn't seem very helpful :( .  Something has
installed it to the Windows folder on my Vista machine, but I've got the
MS Free compiler on there, which likely included it.  I seem to recall
that Python 2.5 included msvcrt71.dll but that there were problems with
redistributions of it (or something like that)... hmm, it's not
installed in the Python25 folder, so it could be that's what did the
system-level install.

What's really weird is that PyOpenGL without the accelerator module is
pure Python... that is, it's not even compiled, it just uses ctypes to
access the dlls.  Maybe in compiling one of the dlls we bundle as data
(maybe GLE?) I produced a dependency on vc7's redistributable.  If you
move OpenGL/DLLS/gle32.dll and OpenGL/DLLS/glut32.dll do you still get
the message?

Hmm, reading again, you're saying the *installer* is failing... hrmph. 
Probably built the pure-python installer with Python 2.5 and it linked
to the Python 2.5 runtime... why would an installer require an external
run-time?  Sigh.  Work-around would be to run the source installation
(i.e. download, unpack, run "python setup.py install") or even use
"easy_install <thezipfile>" if you want.

Thanks. Yes, it is the installer that gave the warning.

I tried downloading the zip files according to your last suggestion.

It worked for PyOpenGL-3.0.1b2.zip but not for
PyOpenGL-accelerate-3.0.1b2.zip. Here's the output for th accelerate
attempt.

f:\PyOpenGL-accelerate-3.0.1b2> python setup.py install
running install
running build
running build_py
running build_ext
building 'OpenGL_accelerate.wrapper' extension
Unable to import Numeric, skipping Numeric extension building
error: Unable to find vcvarsall.bat

Hmm, you *should* be able to use the PyOpenGL-accelerate .exe installer,
it was built with Python 2.6 (since that's the only thing that can build
a binary extension for itself).  PyOpenGL is cross-version, so it
doesn't necessarily get built with the current version (which I think
was the problem here).  The source install of PyOpenGL-accelerate
requires a C compiler, which is a large download for Win32 systems.

HTH,
Mike
