Regarding the implementation status of Fortran 2003 and Fortran 2008 features, see ACM SIGPLAN Fortran Forum (http://doi.acm.org/10.1145/1667140.1667145) - or slightly older at http://fortranwiki.org/fortran/show/Fortran+2003+status For gfortran see also for the status http://gcc.gnu.org/wiki/Fortran2003Status http://gcc.gnu.org/wiki/Fortran2008Status and for the release notes (changes) http://gcc.gnu.org/gcc-4.5/changes.html http://gcc.gnu.org/gcc-4.4/changes.html http://gcc.gnu.org/gcc-4.3/changes.html > They both have partial, but far from complete support for F2003.

From: Paul Thomas on 15 Mar 2010 10:53 Out of curiosity, during an extremely boring meeting, I downloaded and extracted the equation.com gcc-4.5.0 snapshot package onto a memory stick. I thought that this would be a good test because I have absolutely no administrator rights on my work laptop :-) It worked perfectly. I tried compiling and running a few progams and encountered no problems. One nice feature of this package is that it, as well as gcc, gfortran and g++, comes with all sorts of bits and pieces like gdb, make etc.. http://www.equation.com/servlet/equation.cmd?call=fortran Regards Paul Thomas

It all gets installed without much ado. I like it better than some of the other distributions I know of. Regards, Arjen

So maybe the installation on that stick won't work on another machine. What I like to do is to create a new command prompt and point it at a new *.BAT file. Here is one for 32-bit gfortran: @echo off Title Build environment for 32-bit gfortran equation solutions set path=C:\gcc_equation32\bin;C:\gcc_equation32\libexec\gcc\i386-pc-mingw32\4.5.0;%path% set EQ_LIBRARY_PATH=C:\gcc_equation32\i386-pc-mingw32\lib;%EQ_LIBRARY_PATH% If you put such a command prompt and Shortcut.bat file on your thumb drive then I would give it a better chance of working when plugged in to another random (Windows) computer. You could test this by taking your thumb drive to a coffeeshop and borrowing anyone's laptop. Mmmm... but how do you know the drive letter for your thumb drive on the computer you are going to plug it in to? I'm sure there's a solution, but it might make the Shortcut.bat file a bit more complicated. -- write(*,*) transfer((/17.392111325966148d0,6.5794487871554595D-85, & 6.0134700243160014d-154/),(/'x'/)); end
