Error while compiling Fortran routine
 

Hi Everyone

I am getting following error, while trying to create shared library for the user sub routine, MomentumSource1.F used in one of the Ansys CFX 10 tutorials ...

C:\cfx\test1>cfx5mkext MomentumSource1.F

I went through the older posts but couldn't get much out of them. Can anyone help me out. Thanks in advance.

Re: Error while compiling Fortran routine
 

Hi,

I guess you use a windows platform? The manual says that for this case Compaq Visual Fortran 6.5 or later is required and sucessfully tested.

Perhaps your compiler is not suitable for CFX-10. You could also try to use the command " ! system ("cfx5mkext <name_of_routine>.F") == 0 or die; " in CFX-Pre under Tools>CommandEditor. Another reason can also be that spaces are not allowed in the file name.

Hope this helps.

Hi all,

i am also getting same error while compiling in command line

Hi Selvam,

I am not an expert, but I think your case is different. You have an error in your routine. During the compilation the compiler proofs, if your routine is correct and stops when an error occurs. It seems that you didn't define your external variable.
