Execution

  • --omit-frame-pointer leads to failure of C++ throw for some GCC compiler versions (GCC 3.3 and 3.4, for example). Suggested solutions:
    1. If possible, upgrade to a GCC version which does not have this problem. GCC 4.1.1 is known to work correctly in many environments.
    2. Use the variables OPT_CXXFLAGS, OPT_CFLAGS, and OPT_FFLAGS to override the default optimisation options when executing configure. To determine the correct set of options, look for the string omit-frame-pointer in BuildTools/coin.m4. Currently (06.10.20), adding
      OPT_CXXFLAGS="-O3" OPT_CFLAGS="-O3" OPT_FFLAGS="-O3"
      

to the command line options for configure should do the trick.
