Hi Marcus, I have checked my matlab installation and I can launch standalone matlab under both 32 and 64 linux. The code snippet from Mathworks is: /* * Start the MATLAB engine locally by executing the string * "matlab" * * To start the session on a remote host, use the name of * the host as the string rather than \0 * * For more complicated cases, use any string with whitespace, * and that string will be executed literally to start MATLAB */ if (!(ep = engOpen("\0"))) { fprintf(stderr, "\nCan't start MATLAB engine\n"); return EXIT_FAILURE; } ... Under 32b linux the program continues and executes sample commands. Under 64b linux, the return code from engOpen is *not* zero and I get the can't start matlab engine error.

I have open SuSE 10.2 32 and 64 bit installed on the same machine.

I compile a small matlab example under 32b (either by booting 32b linux or -m32 compiler flag) and run under 32 and 64 bit linux. The code compiles under both environments.

However, the code runs normally under 32b linux, but the 64b linux runtime causes an error condition and the sample code exits.

I have the 32 bit environment loaded under the 64b installation. Yet, there is a subtle difference which is causing this problem.

I've checked the shared libs used in each case and they are identical. I cannot figure out what is causing this issue?

Any help is greatly appreciated!

can you add the error message please. my crystal ball is overheated. darix -- openSUSE - SUSE Linux is my linux openSUSE is good for you www.opensuse.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org ____________________________________________________________________________________ Yahoo! oneSearch: Finally, mobile search that gives answers, not web links. http://mobile.yahoo.com/mobileweb/onesearch?refer=1ONXIC -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
