[Ipopt] Get errors of the Ipopt Mex file in Matlab

[Gao, Z.]

Hello all,

I am trying to use Ipopt in Matlab. I (succesufully?) generated an ipopt.mexglx file and added its path to matlab. But when I tried to run the examples, I got this message:

  >> examplehs038
  ??? Invalid MEX-file '/home/gao/CoinIpopt/build/lib/ipopt.mexglx':
  /opt/matlab/R2008a/bin/glnx86/../../sys/os/glnx86/libstdc++.so.6: version
  `GLIBCXX_3.4.9' not found (required by
  /home/gao/CoinIpopt/build/lib/libipopt.so.0).

  Error in ==> examplehs038 at 33
    [x info] = ipopt(x0,funcs,options);

It seems possibly that my gcc version is inconsistent with libstdc++, so I check their versions. And I have

It seems OK. I have no idea what's going wrong. I am using matlab 7.6 and ubuntu 8.04 and run the configure script via

  ./configure  \
       ADD_CXXFLAGS="-fPIC -fexceptions"        \
       ADD_CFLAGS="-fPIC -fexceptions"          \
       ADD_FFLAGS="-fPIC -fexceptions"

Thanks.
