Matlab 7.4.0 (R2007a) Install

1
Hi,

I just upgraded by R2006b version of Matlab to the latest version
7.4.0 R2007a. I had already installed Psychtoolbox on my earlier
version of Matlab and proceeded to re-install it to function in the
latest Matlab release. When I re-installed Psychtoolbox, it erased
the old Psychtoolbox folder, downloaded everything ok, seemed to
install it ok, but when it got to the post-install routine, I got
errors regarding "asserting OpenGL". I closed Matlab 7.4, re-opened
it, and tried to run a script of mine that uses Psychtoolbox calls
(and had run successfully with my R2006b version of Matlab), but got
the following error message:

??? Invalid MEX-file 'C:\Psychtoolbox\PsychBasic\Screen.dll': The
specified procedure could not be found.

Error in ==> <my script>
Screen('CloseAll');

I'm running Matlab on a Pentium 4 CPU running WinXP Pro 2002 Service
Pack 2, ATI Radeon X600 on a Dell LCD monitor.

Any suggestions on what's happening?

You can download the source (see help UseTheSource, or the Wiki) and compile it yourself,
but that's a fair bit of work. I'll have a look at the 2007a issue around beginning of April,
so depending on how well that goes its rather weeks than months.

Delphine (see message 6071) seems to have managed to compile from source, maybe she
can provide you with some recompiled working mex files in the meantime. Some of the
mex files may still work because they are compiled against later Matlab versions, but
Screen won't work...
