[kepler-dev] questions about matlab actor in 64 bit window 7.

Tue Apr 27 18:04:45 PDT 2010

Hi Jianwu,
Hmm, I don't have a Windows 64 platform on which to try Matlab.

However, the problem below looks to be something to do with gcc?
The message:
 > gcc: installation problem, cannot exec 'cc1plus': No such file or directory
is suspect

BTW - Cygwin under Windows is rather pathetic these days.
- Christopher Faylor broke GNU make under Cygwin, see
http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII7.0/limitations.htm

- When I install Cygwin, the c: file system is mounted in such
a way that shell scripts don't work, see
https://lists.eecs.berkeley.edu/sympa/arc/ptolemy-hackers/2010-04/msg00017.html

In addition using JNI under Cygwin has been difficult.  It has been best
to invoke a C binary and then invoke Java, see $PTII/jni/launcher.

That said, under Cygwin under Windows, I've found it easiest to work with the code
in $PTII/jni and get those tests working first as the tests are simple.

Another issue is that every version of Matlab might require a different
share library.  In addition, we have the 32bit vs 64bit issue.   Fortunately
most platforms are moving towards 64 bit, so this will go away in the future.
However, if we are to support Mac OS X, Windows and Linux, then we may need
32 bit and 64 bit versions for each platform (total 6).  Also, there could be JDK
version dependencies, so if we want to support JDK 1.5 and 1.6 then we could have
12 files.  If we want to support the most recent version of Matlab and one version
back, then that is 24 files, or at least as many 24 different tests that we
should do.

Sigh.

I'm traveling this week and off the network on Wednesday.
