Locating the source file and line for a runtime error

[Jon_D]

Hello,

I am using Intel Fortran 2024.0 with VS 2022. Previous versions of the compiler listed the source file and line number where a runtime error occurred when the program was compiled in Debug mode. With this version of the compiler Routine, Line and Source are all listed as Unknown.  This is the case for both ifort and ifx. Is there a compiler setting that will show this information?

Thank you.

Jon

/traceback  It is the default in a debug configuration, but not in a release configuration. It's under Fortran > RunTime.

Thank you, Steve. /traceback is on but I am still not getting the source file/line number information.

Please provide a short example. I tried this:

D:\Projects>type t.f90
implicit none
integer :: a(5) = [1,2,3,4,5]
integer :: i
do i=1,10
print *, a(i)
end do
end

D:\Projects>ifx /traceback /check:bounds t.f90

It turns out linker setting -incremental was set to "default" in my project. Following the settings in your example, I changed it to NO and I am now able to see the proper information. Thank you, Steve.

Good to know. The default when a Fortran project is created is No for this setting.
