plplot.mod
Comment 2 Orion Poplawski 2012-01-29 00:22:59 UTC 
Compiles fine with 4.6.2-1.fc16
Comment 3 Jakub Jelinek 2012-01-29 08:15:51 UTC 
plf95demolib.mod hasn't been provided.

plf95demolib.mod
Comment 5 Jakub Jelinek 2012-01-30 11:30:42 UTC 
That last mod file looks to be gcc 4.6* generated rather than 4.7.

plf95demolib.mod

Sorry about that, this should be the right one.
Comment 7 Jakub Jelinek 2012-01-30 17:01:15 UTC 
Narrowed down to:
program x09f95
    use plf95demolib
    integer, parameter :: nptsx=35, xdim=99
    real(kind=8)   :: xg1(xdim), distort
    xg1 = foo (arange(0,nptsx) / dble(nptsx-1), distort)
contains
elemental real(kind=8) function foo( coord, factor )
    real(kind=8), intent(in) :: coord, factor
    foo = 1
end function foo
end program x09f95

but it doesn't fail without the plf95demolib use, could you please attach the *.f90 file in which the module is defined?

That link is already in the External Trackers section.
Comment 11 Orion Poplawski 2012-02-06 16:27:20 UTC 
Can we get this into rawhide soon (before the branch maybe)?  I can't build plplot until this gets in and I need to fix broken dependencies.  Thanks!
