gfortran - nonconforming tabs warning

(1/2) > >>

gib:
Since my Fortran code has a great number of tabs, the compiler warning is very annoying - the great number of tabs warning messages drowning out other warnings.  I've followed suggestions that either -Wtabs or -Wno-tabs has the effect of suppressing these warnings, but in CB neither has that effect.  Does somebody know the solution to this?

Thanks
Gib

No, that doesn't help.  I'm sure some other Fortran programmers using CB must have encountered this issue.
To check how gfortran behaves outside of CB, I compiled a trivial test program:

--- Code: ---program main
integer :: i, j, k
k = 0
do i = 1,10
do j = 1,3
k = k+10
enddo
enddo
write(*,*) 'k: ',k
end program
--- End code ---

where the indentation on lines 5,6,7 uses tabs.

Compiled with
>gfortran -c test.f90
there are no warnings.
With
>gfortran -c -Wtabs test.f90
there are 3 tabs warnings
With
>gfortran -c -Wno-tabs test.f90
there are no warnings.

Using -Wtabs, -Wno-tabs or no compiler option in CB gives tabs warnings.  I have not been able to find any combination of compiler switches that turns these warnings off.  It is frustrating.

It says this:

This is done by selecting the "Full command line" option Under menu "Settings" -> "Compiler" -> Global compiler settings -> [the compiler you use] -> "Other Setting" tab, "Compiler logging". In 12.11 and newer this is enabled by default.

* You should review all the commands and their options;

Have you done it? Are they the same as the ones for your command line invocation of the compiler?

and there:

--- Quote ---Build log:

--- Code: ---Paste full build log here. (It is found in the 'Build log' tab). Please make always a 'rebuild' (Menu: Build->Rebuild) or a 'clean' and 'build' before you copy the full build log.
