I am only used to MS forten 5.1 on dos, so do you have a "hello world" kind of program with batch or make example to compile/link? Just to get started, here or email(replace nulnulfour, and remove double letters in last part).

AFAIK, Equation.com replaced libgomp, the threaded library for OpenMP support, by their own proprietary version. They may have made other changes to the compiler, but they haven't released anything back to GCC if they have. > What is their motivation for doing so ? You would need to ask someone at equation.com. Based on their statement "Binaries distributed at this site are a variant of GCC. Distributions of Equation Solution have indepentent settings." You can request the source code that they used to build their binaries, but don't hold your breath. -- steve

I had to convert the table from Markdown to HTML, which will make it slightly more difficult to edit, but visually I think the result is very nice. Thanks for the suggestion. -- Jason Blevins Ph.D. Candidate, Department of Economics, Duke University http://jblevins.org/

Start up windows Explorer with <WINDOWS>+E key combination, navigate to thumb drive root, and clean up root directory. I just created a new directory call "Backup" and dragged everything into it. Then create a new directory call gcc_eq32 in the root directory. Start Internet Explorer and go to www.equation.com, click on the Programming Tools link, then the Fortran,C,C++ link and scroll down to Download: Weekly Snapshot, and click on the link to download the 32-bit snapshot. When the little window pops up and asks if you want to run of save, click on Save and navigate to your thumb drive and the gcc_eq32 directory, then click on Save. Now back in Windows Explorer, navigate to the gcc_eq32 directory and double-click the installation executable that you just downloaded. Accept the terms, and in the next dialog box click on browse and browse to the gcc_eq32 directory. Click OK but delete the extra \gcc in the installation directory name, then click on Install. After installation, you need a couple of extra things to make this work cleanly. First, select your gcc_eq32 directory in Windows Explorer and from the menu bar select File | New | Text document. Change the name to Shortcut.bat, right-click on the file and select Edit from the drop-down menu. Paste in this stuff: @echo off Title Build environment for 32-bit gfortran equation solutions set path=%cd:~0,2%\gcc_eq32\bin;%cd:~0,2%\gcc_eq32\libexec\gcc\i686-pc-mingw32\4.5.0;%path% set EQ_LIBRARY_PATH=%cd:~0,2%\gcc_eq32\i686-pc-mingw32\lib;%EQ_LIBRARY_PATH% cd %cd:~0,2%\gcc_eq32 (correct any line wraps above) and then exit Notepad, saving the file. Next, start up another instance of Windows Explorer and using the right mouse button, drag and drop C:\WINDOWS\system32\cmd.exe to the root directory of your thumb drive and select Create Shortcut from the drop down menu. Right-click on the shortcut, select Properties, and under the General tab change the name to Command Prompt for 32-bit gfortran Under the shortcut tab, change the target to C:\WINDOWS\system32\cmd.exe /K %cd:~0,2%\gcc_eq32\Shortcut.bat Change Start in to %cd:~0,2%\gcc_eq32 And under the Options tab, make sure that QuickEdit mode and Insert mode are checked. Click on OK, and you should have a working thumb drive installation. So now I tried starting up Windows Explorer, and from there double-click the Command Prompt for 32-bit gfortran and got the following session: F:\gcc_eq32>dir Volume in drive F has no label.
