Bug 440682 – =sci-libs/hdf5-1.8.9-r2 please stabilize

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sean Santos 2012-11-01 02:45:02 UTC]

hdf5 seems to require quad precision to compile, which was only added to gfortran via libquadmath in 4.6 (at least for common architectures; I wouldn't know if there was some machine that had quad support earlier). For me, emerging hdf5 (the first and only stable version right now) stopped on a line with "KIND=16", with gfortran noting that the kind was unsupported.

Hopefully gcc 4.6 is stabilized soon. Even so, I think that the dependency should be added.

[Comment 1 François Bissey 2012-11-01 02:56:23 UTC]

which versions of hdf5? I compile hdf-1.8.9 with gcc-4.3 on SLES11 box at work so I am bit surprised by this claim.
Can you attach a build log of a failed install with gcc<4.6?

[Comment 2 Sean Santos 2012-11-01 03:24:53 UTC]

This is sci-libs/hdf5-1.8.8-r1. To be clear, compiling with the fortran USE flag is the problem, because this is an issue specific to gfortran. I would not be surprised if everything else works fine with gcc-4.3.

Here's the error message:

mpif90 -O2 -pipe -march=native   -I../../src -I../../fortran/src -O2 -pipe -march=native -c -o H5fortran_detect.o  H5fortran_detect.f90
H5fortran_detect.f90:175.16:

   REAL(KIND= 16) :: a
                1
Error: Kind 16 not supported for type REAL at (1)
H5fortran_detect.f90:178.21:

    a_size = SIZEOF(a)
                     1
Error: Symbol 'a' at (1) has no IMPLICIT type
make[2]: *** [H5fortran_detect.o] Error 1

There are a prodigous number of warnings, so the log is too large to attach, but I think this is the only relevant part as I can reproduce the error in a short program:

  program test
    integer, parameter :: qk = 16
    real(qk) :: a = 1._qk
    write(*,*) a
  end program test

With gfortran 4.5.4 this yields:

test.F90:5.9:

  real(qk) :: a = 1._qk
         1
Error: Kind 16 not supported for type REAL at (1)

It's a dupe of bug 419895. Please use hdf5-1.8.9. I'll reuse this bug for stabilization.

[Comment 4 Kacper Kowalik (Xarthisius) (RETIRED) 2012-11-01 08:50:54 UTC]

Couple of bug fixes, notably the one described originally in this report. Arches please do your magic!

@alpha, @ia64, @sparc
Guys you may consider skipping this version and go ahead straight to 1.8.10. I'll request stablereq for it later this week.

Don't forget to file the stablereq for the new autoconf before asking 1.8.10 stable
