Sorry, I have forgotten to show swig version, so here it is: $ swig -version SWIG Version 1.3.29 Compiled with g++ [x86_64-redhat-linux-gnu] Please see http://www.swig.org for reporting bugs and further information

Hi, thanks for using the module and for the thorough bug report. I was just able to reproduce your issue, and it turned out to be the SWIG version. I had managed to compile against all versions back to 1.3.28, but did not have thorough enough unit tests to catch this issue. It appears that SWIG 1.3.33 is actually the minimum compatible version that supports 'typedef' in the way that F::IB::SWIG needs it to. I will update the module accordingly, but in the meantime, just upgrade SWIG to at least 1.3.33 (though preferably newer...), and you should be good to go.

Thank you very much! I have updated manually to swig-1.3.36-50.1, and Finance::InteractiveBrokers::SWIG now works perfectly.
