New in Fortran 2

[javijerome]

Hi guys! i'm new in fortran. i'm very interested in it. however, i don't know where to start. i'm running windows7 and i'm a basic programmer. i have been using C and visual basic as my main programming language. i have a little knowledge about php, python, visual c#, and java.

Then start with reading an introduction - for example here:

http://www.tcm.phy.cam.ac.uk/~mjr/f1nn.pdf

And if you don't have a Fortran compiler installed, then download any free compiler - for example here:

(I would recommend g95 and gfortran)

 

[javijerome]

thanks mikrom. the intro pdf file was a great help.
though i actually found an IDE for fortran95 that i downloaded from silverfrost.

i had some problems installing g95 and gfortran. i can't seem to find some installation procedures.

I think g95 and gfortran can't be installed at the same time for some reason. I remember that I've been answered something like this on this forum when had problems with it myself.

Try deleting both compilers and install the one you like most on a clean system.

On windows you can download gfortran auto-install at:

http://gcc.gnu.org/wiki/GFortranBinaries#Windows

Or directly:

http://users.humboldt.edu/finneyb/gfortran-windows.exe

Just run the executable and everything will install fine.

thanks gerritgroot!

Does it work now?

I think xwb told me this once, he/she is also active on this forum.

I think g95 and gfortran can't be installed at the same time for some reason.

It's possible: I have all 3 compilers running on the same Windows Vista computer: g77, g95 and gfortran. I use them all for test purposes in the MSYS/MinGW environment and haven't noticed any problem.

1. I installed MSYS + MinGW and got g77 with it.

2. Then I installed g95-MinGW.exe from

http://www.g95.org/

I have both g77 and g95 in the directory C:\msys\1.0\mingw\bin. After the installation of g95 the directory C:\msys\1.0\mingw\bin need to be in the path and we need to set the variable
LIBRARY_PATH=C:\msys\1.0\mingw\lib\gcc-lib\i686-pc-mingw32\4.0.4;C:\msys\1.0\mingw\lib

3. Then I installed gfortran-windows.exe in C:\Program Files\gfortran. Now gfortran works standalone from the windows command line or from MSYS. There are no conflicts in MSYS with g77 or g95.

Note: g77 should be now obsolete, replaced by gfortran. So you have install only gfortran and g95. gfortran should be available with actual version of MinGW with gcc 4.x. I have older installation with gcc 3.4.5 which was delivered with g77. Read about other installation problems here:
