Current Issues


  • Configure is unable to find the symbol glp_lpx_simplex when checking for the presence of glpk. Glpk has changed its naming convention for API routines. This is normally invisible to users of glpk (who always use lpx_simplex in code). Current COIN configuration tests understand this; the best solution is to upgrade.

If that's not convenient, the workaround is to use the configuration flag --disable-glpk-libcheck. If you have the ability to regenerate configuration files, add a leading underscore ('_') to the symbol in relevant files. For example,




The same problem exists with glp_mpl_initialize; the workaround is --disable-gmpl-libcheck or edit to look for _glp_mpl_initialize.


  • On AIX, with the xlC compiler the CXX flag -qrtti has been needed.
    ./configure ADD_CXXFLAGS="-qrtti"

  • On P-Series(ppc64) running Linux(Red Hat 4.1.1-52) with gcc(V 4.1.1 20070105) ThirdParty/ASL has compile time errors.
    fpinit.c: In function 'fpinit_ASL':
    fpinit.c:123: error: '_FPU_EXTENDED' undeclared (first use in this function)
    fpinit.c:123: error: (Each undeclared identifier is reported only once
    fpinit.c:123: error: for each function it appears in.)
    fpinit.c:123: error: '_FPU_DOUBLE' undeclared (first use in this function)
    A suggested work around is to specify ADD_CFLAGS="-DNO_fpu_control" when running configure.
    ./configure -C ADD_CFLAGS="-DNO_fpu_control"


  • --omit-frame-pointer leads to failure of C++ throw for some GCC compiler versions (GCC 3.3, 3.4, and 4.0.2, 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

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