This is again related to the failure of execution of a gfortran built binary ("cannot execute binary", see thread http://cygwin.com/ml/cygwin/2011-11/msg00034.html )
In short, the main problem is that I can't build a successful binary from the FLEXPART fortran code (just google "FLEXPART nilu" if you are curious of what FLEXPART is) on a cygwin installation I did just over a week ago, but it builds and run without problem on an installation from October 3. I get no differences in warnings from the bad build compared to the good one, so I really don't know what to look for. So far I have come to the conclusion that this must be related to one or several changes in the cygwin distribution done after October 3. Through try and failure testing I found that this is not affected by gfortran/gcc as both gcc 4.3.4 and gcc 4.5.3 works. The latter hangs on '$EGREP' calls in the 'grib_api' (required library) configure script, but the workaround of changing to 'egrep' works fine. I have posted the output from strace, objdump and cygcheck for some of you to look at in the former thread, but it seem like this is far from a straight forward problem. I can see from the [ANNOUNCEMENT] posts that a few things in this cygwin distro have been updated since October 3 and I kindly ask if someone have an idea of what updates since then may cause a badly gfortran built binary if it has nothing to do with gcc alone? I will now start going through the updates and change back to versions yielding October 3 if possible. I think this is important since cygwin will give the opportunity to run and develop FLEXPART on Windows machines the way linux-users are used to. In addition, I also see a potential problem of other fortran software that people want to run under cygwin. Regards, Kåre
