--- Begin Message ---Thank you Bastian! I've adjusted matlab_r2006b/bin/mbuildopts.sh on the box to use g++ as the linked and it works now fine ;-) Thank you very much and once again, sorry for the ignorance ;-) P.S. I am closing the "bug" since the issue got resolved P.S.S. Vladimir - just use the most recent r2006b release of Matlab ;-) On Mon, 18 Sep 2006, Bastian Blank wrote: > On Sun, Sep 17, 2006 at 06:27:26PM -0400, Yaroslav Halchenko wrote: > > After recent upgrade, mcc (Matlab compiler fails to compile) with next > > error messages: > This update changed the default compiler from gcc-3.3 to gcc-4.0. > > r14sp3 release of matlab: > > -> gcc -O -pthread -o test test_main.o test_mcc_component_data.o > > -Wl,-rpath-link,/share/apps/matlab_r14sp3/bin/glnx86 > > -L/share/apps/matlab_r14sp3/bin/glnx86 -lmwmclmcrrt -lm -lstdc++ > > /usr/bin/ld: warning: libstdc++.so.5, needed by > > /share/apps/matlab_r14sp3/bin/glnx86/libmwmclmcrrt.so, may conflict with > > libstdc++.so.6 > Read this line carefully. matlab wants libstdc++.so.5, the new binary > wants libstdc++.so.6.
