[Gmsh] compilation error in Fltk

[Orlando.Rivera at lrz.de]

Hi

I have a weird error by compiling under linux,   my configure is:

./configure CC=icc CXX=icpc CFLAGS="-O3 -ipo" CXXFLAGS="-O3 -ipo"
F77=ifort FFLAGS="-O3 -ipo"
--prefix=/lustre_projects/pr28fa/a2815ag/gmsh/2.5
--with-fltk-prefix=/lustre_projects/pr28fa/a2815ag/gmsh/fltk-1.1.9
--with-gsl-prefix=/lrz/sys/libraries/gsl/1.11 --enable-cgns
--with-cgns-prefix=/lustre_projects/pr28fa/a2815ag/gmsh/cgnslib-2.5
--with-hdf5-prefix=/lrz/sys/HDF5/5-1.6.5-amd-gcc
--with-fftw3-prefix=/lrz/sys/libraries/fftw/3.1.1


Specifically Fltk/GmshServer.h
the error is around  line 106


#if defined(HAVE_NO_SOCKLEN_T)
     int len;
    // I replaced by socklen_t len;
#else
    socklen_t len;
#endif
    if(_portno < 0){
#if !defined(WIN32) || defined(__CYGWIN__)
      struct sockaddr_un from_un;
      len = sizeof(from_un);
      return accept(s, (struct sockaddr *)&from_un, &len); //<< error here
#else
      return -7; // Unix sockets not available on Windows without Cygwin
#endif


when HAVE_NO_SOCKLEN_T is defined  len is integer   and accept(s, (struct
sockaddr *)&from_un, &len)  expects  a &socklen_t  as 3rd parameter and
not an integer


so I just replaced to be len as sockeln_t  ,and I went  through   and  it
seems to work ,  the question is :  is this a time bomb that will affect
me in the future ,  what  GmshServer.h actually do?


Regards

Orlando
