Hi all,

I am not able to compile the user subroutine in the tutorial example of butterfly valve. I used the following command

c:\temp>cfx5mkext PipeValve_inlet.F

follwing error is obtained:

A fatal error has occurred in cfx5mkext:

The compiler command "df" could not be found. Please ensure that the compiler is on your PATH and try again.

My db files are created in c:\temp whereas my cfx5mkext.ccl file is stored in c:\CFX\CFX5.5.1\etc\5.5.1

CFX manual says that if the commands do not execute the FORTRAN compiler on your platform, then you will will have to manually edit a copy of the CFXROOT/etc/5.5.1/cfx5mkext.ccl file and place it in the working directory. The cfx5mkext command will look for a copy of cfx5mkext.ccl in the current working directory first.

QUESTIONS:

1) In this case, is temp my working directory?

2)What changes i have to make while manually editing the cfx5mkext.ccl file as mentioned by the manual?

I am using CFX 5.5.1 and FORTRAN 90.

Please let me know how to resolve this problem.

Thanks.

1) Yes, temp is your working directory 2) You don't need to edit the cfx5mkext.ccl file, you just need to make sure that executing the command 'df' at the command prompt finds the FORTRAN compiler executable. You have an environment variable called PATH, this lists the directories which are searched for the executable. The directory in which your FORTRAN compiler executable is located needs added to the list of directories in PATH. hope this helps Mike

Hi Mike,

The Fortran compiler executable is in the path (i checked this with the command PATH). The Fortran Compiler on the machine is Essential Lahey Fortran 90 (ELF 90). The command to compile the Fortran File is elf90. I edited the cfx5mkext.ccl file by changing the parameter df! to elf90!. (see following comand which is part of cfx5mkext.ccl file.

OS: winnt

cc = cl

fc = df!

ld = link

ext build cflags = -MD

ext link ldflags =

ext link lib5files = solver-pvm.lib

cppincflag f = -include:

cppflags f = -fpp:-m

fc outopt obj = -object: fc outopt exec = -dll: cc outopt obj = -Fo ext lib suffix = dll ext lib pattern = %s.dll ATTRS: double

cppflags = -DDOUBLE_PRECISION

ext build fflags = -integer_size:32 -real_size:64 -MD

ext link lib5files = solver-pvm.lib END END

But still it gave me the same error as for df. Then i removed the ! sign in fc=elf90!(see above commands; replace df by elf90) so that fc=elf90. Then when i executed the command c:\temp> cfx5mkext PipeValve_inlet.F ,it worked ,but it gave me 76 errors. The PipeValve_inlet.F file is there in examples (created by CFX people). I was not expecting any errors.

1)what might be the reasons for these errors?

2)Can you check if your cfx5mkext.ccl file also has ! sign for the line fc=df! (see above commands).Because in my ccl file this ! is only there for winnt OS and not for other OS.

Are you sure CFX supports the elf90 compiler? I believe elf90 is not a full fortran 90 compiler but I may be wrong. It looks like the compiler doesn't like the fortran 77 style comment C. You may want to go in and change all the comment lines which begin with C to lines which begin with ! which is the fortran 90 style comment.
