Add entries about MinGW/Msys PATH order under configuration and compilation

Current Issues

Configuration

  • Under cygwin with Intel 11 compilers, the intel compiler might pick up the wrong link.exe, which results in failures setting up the FFLAGS and in failures when linking a binary. You can tell the Intel compilers where to find the right link.exe by editing the files icl.cfg and/or ifort.cfg in the Intel compiler installation. The line to add is of the form
      -Qlocation,link,"C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\Bin"
    
  • On MacOS X, if you use the Intel 10 compilers and build static (or debug) libraries, it is wise to set F77 to "ifort -shared-intel" to avoid later problems when COIN-OR libraries are linked to each other.
  • On MacOS X 10.5, you should use
      ADD_CXXFLAGS="-mmacosx-version-min=10.4" ADD_CFLAGS="-mmacosx-version-min=10.4" ADD_FFLAGS="-mmacosx-version-min=10.4"
    
    This helps to get around a problem with the Ampl Solver Library (ASL) and in the recoginition of the FLIBS (in case gfortran is used). This flag avoids undefined references to something with an $UNIX2003 attached, see also http://developer.apple.com/releasenotes/Darwin/SymbolVariantsRelNotes/index.html
  • On MacOS X 10.5, if you get failures when running the code due to lazy symbol binding, try to rebuild everything with LDFLAGS="-flat_namespace". However, this solution might fail too.
  • On MacOS X 10.6, it is sufficient to add to the configure command
      ADD_FFLAGS="-mmacosx-version-min=10.4"
    
    Do not ADD_CXXFLAGS="-mmacosx-version-min=10.4" or you will have problems with try catch causing ABORT TRAP errors. If you are going to compile with ASL you should also try to build static libs by adding
       --enable-static --disable-shared
    
  • "./configure: line 20: $'\r': command not found" error on Cygwin. If you see an error like this on Cygwin, it means that your setting for Cygwin is such that the native text style is "Windows" and not "Unix". As a consequence, the configure and other shell scripts have Window-style line end characters, which cannot be digested properly by the shell. As a work-around, you can run the "dos2unix" program to correct all failing shell scripts (e.g., by typing "dos2unix configure"). In the long run, we will change the subversion properties for those files to avoid this problem, but it might take some time until all files have been corrected.
  • When using MinGW and Msys, you may see failures that really leave you scratching your head. Before you tear your hair out, check your PATH. Both Windows and MinGW/Msys define some common utilities: find, link, and sort. Unfortunately, the Windows versions are completely incompatible with the unix versions. Make sure that the MinGW/Msys command (bin) directories come before the Windows command directories in your PATH! Both the configure and libtool shell scripts can fail if this is not true. If you're trying to build with Windows cl and link (you can see the problem coming eh?) make sure that the Visual Studio command directories precede the MinGW/Msys command directories, which in turn must still precede the Windows command directories. Unix link is not helpful for linking programs!

Compilation

  • 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"
    
  • In Microsoft Windows, using the MinGW gcc compiler version 4.2.1 under Msys, you cannot successfully link with -lstdc++ because of a buggy .la file. To fix, replace the file MinGW/lib/gcc/mingw32/4.2.1-sjlj/libstdc++.la with this fixed one. This currently affects only the unit test of Ipopt (as far as I know).
  • When using MinGW and Msys, you may see failures that really leave you scratching your head. See the entry under configuration. During build, the failure is due to libtool finding Windows sort instead of unix sort.
