    @m^2: can you please write something more to explain - which software will be open ?

    i can not found hints about this ..

    on http://www.pathscale.com/enzo is written about PathScale ENZO 2011

    All I know is written in the 3 links provided.
    It's not entirely clear ATM what's going to be released, but there's a strong indication that it's EkoPath mainly because
    -there was information that a product that's going to be release was priced $1795 which matches EkoPath
    -the option to buy it disappeared from the Pathscale website.

    It happened:

    Sadly, it's GPL.

    So can we use that EKOpath to compile commercial programs?

    Yes. It's GPL, like gcc.

    I see only free trial on PathScale site, and even there's a price for EKOpath (1795 USD) on Main Page. Is that wrong? Where can I download the full version?

    It seems they need to update the site...
    Anyway, http://www.pathscale.com/ekopath4-op...e-announcement so it's true.
    There is some chance that if you download the trial , you're gonna get the real deal, but personally I decided to wait.

    Download link (didn't try it, it's supposedly x64 and my Linux machine is not):
    http://c591116.r16.cf2.rackcdn.com/e...-installer.run

    A statement from a PathScale team member:
    If we're not faster than g++ or other compilers file a bug report

    here we can found the source-code for compiler and debugger

    https://github.com/path64/compiler
    https://github.com/path64/debugger

    compiler is under GPLv3 and debugger is under Sun-CDDL

    but a binary for SUSE LINUX ENTERPRISE SERVER 11 or other linux ...

    best regards

    Well, EKOpath was written for HPC and HPC is Linux/ Unix/ BSD, not Windows or Mac. So Windows and Mac weren't a priority for them. On the other hand, on their site there's an indication that EKOpath should support Windows and Mac from Q1 2011.

    windows version is still too early and now there is no timeline

    a link to an actual linux binary we find on the website
    http://www.pathscale.com/ekopath-compiler-suite

    under the point:

    Nightly download - EKOPath nightly build download

    here is a x64-linux-binary downloadable

    best regards

    It seems I was wrong, it's only for GPL compliant things because parts of it runtime that get embedded with every executable are GPLed.

    So what about GCC? I can't compile commercial, closed-source or non-GPL compatible programs with GCC? GCC with proper tuning often beats EKOpath (from what I saw on the 'net).

    That sounds ridiculous.

    There were several comments about it and from what i got, GCC uses a mix of LGPL and special exceptions for the code that it embeds.

    I succeeded to compile the sources from theses links and compilers seem to work
    ( Scientific Linux 6.1, x86_64, gcc 4.4.5, cmake 2.8.5 )

    but I have two problems:
    - the version is 1.0.0 :

    $ /opt/path64/bin/pathf95 --version
    PathScale (tm) Compiler Suite: Version 1.0.0
    Built on:
    Thread model: posix
    GNU gcc version (PathScale 1.0.0 driver)

    Copyright PathScale Inc and others. All Rights Reserved.
    You can find complete copyright, patent and legal notices in the corresponding documentation.
    - with the version 3.2, to compile NetCDF, I use "CPPFLAGS =- Df2cFortran" due to the "extra underscore" problem
    It seems that with the version 4, it changed : right ?

    thanks
