MATLAB: Am I unable to start MATLAB 6.5 (R13) with Java if I have libvga.so.1.4.1 library file in the /usr/lib directory on a RedHat Linux machine

Why am I unable to start MATLAB 6.5 (R13) with Java if I have libvga.so.1.4.1 library file in my /usr/lib directory on a RedHat Linux machine?

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

This is a bug when using MATLAB 6.5 (R13) with the libvga.so.1.4.1 library file in your /usr/lib directoryX. Our development staff is currently investigating this issue.

The only way to work around this issue is to keep moving the libvga library back and forth to start MATLAB with java.

MATLAB: Do I receive an error about gcc version when executing a MEX-file or an executable generated by MATLAB Compiler on Linux

This bug has been fixed in Release 2007b (R2007b). For previous product releases, read below for any possible workarounds:

This bug has been fixed in Release 2007a (R2007a). For previous product releases, read below for any possible workarounds:

This error may occur when you use MATLAB or MATLAB Compiler in combination with GNU gcc 3.3.x, with gcc 3.2.3 that is distributed by Red Hat, or with another unsupported version of gcc. For the list of supported compilers, consult the following document:

http://www.mathworks.com/support/compilers/current_release/

See the related solution to compile and install a fully compatible GNU gcc. While installing the supported version of gcc is strongly recommended, some of our customers have reported the following workarounds are successful. These workarounds have not been tested and are not supported by MathWorks.

Workaround 1:

Before starting MATLAB (if executing a MEX-file) or before executing a file generated by MATLAB Compiler, set the LD_PRELOAD environment variable to /lib/libgcc_s.so.1

For bash users:

 export LD_PRELOAD=/lib/libgcc_s.so.1

For csh users:

 setenv LD_PRELOAD /lib/libgcc_s.so.1

Workaround 2:

Another workaround is to replace some library files in the MATLAB installation with the corresponding libraries from the version of GCC you are using. Be sure to create backup copies of any libraries you replace, since you may have errors in MATLAB after replacing the libraries. For example in MATLAB 7.1 (R14SP3) you could replace the following files:

libg2c.so.0.0.0 
libgcc_s.so.1 
libstdc++.so.5.0.3

and the symbolic links associated with these files with newer libraries from your gcc release. The files to be replaced are in the following directory:

$MATLABROOT/sys/os/$ARCH

(where $MATLABROOT is the MATLAB root directory on your machine, as returned by typing:

matlabroot

at the MATLAB command prompt and $ARCH is your architecture "glnx86" for 32-bit Linux and "glnxa64" for 64-bit Linux.)

MATLAB: Will MATLAB 6.5 (R13) run on RedHat 9

MATLAB 6.5 (R13) has not been qualified on RedHat 9. There has been several customer-reported issues regarding this version of RedHat and MATLAB, though RedHat 9 uses a 2.4.x kernel, which is supported with MATLAB. (The majority of the reported behaviors are not consistently reproducible.)

Our development team has been notified of the issues relating to RedHat 9 and is currently investigating them, but at this time there are no known workarounds.

Please note that if you are experiencing small MATLAB Java dialog windows on Linux, see the related solutions section at the bottom of this page.
