what happen to gfortran compiler

what happen to gfortran compiler

what happen to gfortran compiler

i have used
gfortran.exe uses.f95 and use gfortran.exe myfile.f95 such as
this aLL files that worked perfectly and compiled no problem
prior now get message. eg Get error

:\Simply Fortran 2>gfortran.exe uses.f95
his version of c:\Simply Fortran 2\gfortran.exe is not compatible with the version of Windo
s you're running. Check your computer's system information to see whether you need a x86 (3
-bit) or x64 (64-bit) version of the program, and then contact the software publisher.

I am doing exaclty the same thing and never got this message before ! Why NOW ?

RE: what happen to gfortran compiler

Have you upgraded to W10?

Which version of gfortran are you using (gfortran --version)

RE: what happen to gfortran compiler

Check your windows updates on the day it stopped working.

RE: what happen to gfortran compiler

No, have not upgraded or changed anything, still windows 7. I am pretty sure it is a 'bogus' incorrect message and I am pretty sure I do have 64bit capability-anyway nothing has changed unless I accidently pushed some wrong keystrokes which I often do and in fact on that occasion certainly did as the source file got really 'muffed' also. Unfortunately I did not think to carefully look at the DOS screen. I did not compile within code blocks as usually don't as it does not work for module anyway. I do the compile in DOS window direct.
I forgot what version it was. i remember there was a way to tell once and i did it but have forgotten how to do that. But get the following when do gcc -v

c:\Simply Fortran 2>gcc -v

I don't think the above is of much relevance though. It is gfortran.exe of 2,023kb. My date on it shows 1/26/2015 but am
pretty sure that date is likely only particular to when I installed.

RE: what happen to gfortran compiler

Oh OK NEVEr mind now found the problem . Wasn't expecting something that blatant. Another thing that seems strange is why do 2 different versions of gfortran NOT even close in size in different directories with very different subdirectory structure and other files give exactly the same as above when
Do gcc -v. Though it could somehow be using the same files etc. ?

RE: what happen to gfortran compiler

Personally I do a full load of cgywin on my windows 7 64 bit and put it's bin directory in my path variable. Now I have all the UNIX utilities on my windows machine with all their functionally and that includes gfortran. Before I did this I uninstalled all versions of gfortran that were already on my machine.

RE: what happen to gfortran compiler

Say, Bill, I did not think cygwin and mingw were the same thing, though; unless they have changed cygwin since last time I used it. As far as I knew, when you compile with cygwin, your program is not a self-contained program and it has to have access to some cygwin.dll at run-time; on the flip side, I think a program compiled with mingw is truly self-contained and can be given to somebody else without mingw.

Maybe just a detail, but worth being aware of it.

RE: what happen to gfortran compiler

Probably worth doing a test build after you download a mingw compiler. Sometimes it doesn't get build correctly and has a dependency on cygwin - this has happened quite a few times. If you use cygwin, you may run into problems if you use utilities which are not part of cygwin but which require a different versions of cygwin.dll

RE: what happen to gfortran compiler

Thats true, however all you have to do is store the cygwin1.dll file in the same directory as the exe and everything will work fine. I will check into mingw. Thanks for the info
