DISLIN actual argument differs from type of dummy argument

rmoortgat — Mon, 20 Oct 2025 07:59:36 GMT

VS 17, ifx compiler, windows 11

Settings:

Release x64

Runtime library: Debug Multithreaded(/libs:static /threads/ dbglibs)

Linker - Input ^Additional dependencies: C:\DISLIN\dl_11_ic\disifl.lib user32.lib gdi32.lib

Fortran - Additional include directories: C:\DISLIN\ifc

call SWGBGD(main_win,1.0,1.0,1.0) ! Set background to white using RGB

Generates the following error:

error #6633: The type of the actual argument differs from the type of the dummy argument. [1.0]
error #6633: The type of the actual argument differs from the type of the dummy argument. [1.0]
error #6633: The type of the actual argument differs from the type of the dummy argument. [1.0]

Manual says:

S W G F G D
The routine SWGBGD changes the foreground colour of a widget.
The call is: CALL SWGFGD (ID, XR, XG, XB)
or: void swgfgd (int id, float xr, float xg, float xb);
ID is the widget ID.
XR, XG, XB are the RGB colour values between 0 and 1.

mod file:

subroutine swgbgd(id,xr,xg,xb)
implicit none
integer, intent (in) :: id
real, intent (in) :: xr,xg,xb
end subroutine swgbgd

Copilot doesn't have a clue and sends me from pillar to post.

Hi @rmoortgat,

Thank you for your continued patience.

After reviewing your concern, we have determined that the issue is not related to any Intel-supported hardware or software. The concern appears to be associated with the Fortran compiler or related software components, which are outside the scope of Intel's supported products.

To ensure you receive the most accurate and effective assistance, we will be moving this thread to our dedicated software support forum, where a specialized team will be able to provide further guidance and support.

Best regards,

The error shows a real data size mismatch between the data passed to the subroutine call and the subroutine call interface definition. I saw both the subroutine call and the module interface are using the default real data type so please make sure the code calling the subroutine and the module file are built with the same default real data size setting.

Real data type in Intel Fortran language reference: https://www.intel.com/content/www/us/en/docs/fortran-compiler/developer-guide-reference/2025-2/real-data-types.html

The compiler option to control the default real data size: https://www.intel.com/content/www/us/en/docs/fortran-compiler/developer-guide-reference/2025-2/real-size.html
