building hdf5-1.8.8 with icc 12

Hdf-forum archives

Hi,
I needed to apply a couple of patches to some config files in order to
build hdf5-1.8.8 with intel version 12 compiler.

I have attached two patch files, gnu-flags.patch and intel-flags.patch.

1) In version 12.1, icc -v returns the message:
icc version 12.1.0 (gcc version 4.4.5 compatibility)

The file $HDF5_ROOT/config/gnu-flags sees the substring "gcc version" and
decides the compiler is gcc
This causes the H5_CFLAGS to be set to flags which are not appropriate for
icc.
There is already logic in this file to deal with the fact that the
PathScale compiler also outputs the gnu version string.
gnu-flags.patch adds similar logic for icc version 12.

2) In $HDF5_ROOT/config/intel-flags there is a case statement at the end
which sets PROD_CFLAGS according to the icc version, but it stops with
version 11.
intel-flags.patch adds the case for icc v12 and assigns the same flags as
for icc v11.

Suggested improvements welcome.

Thanks,
John Eisenlohr

John,

Thank you for the report and patches (patches look good).

We already have an entry in our issues DB for 1) and I just added 2) to it. The issue will be addressed in 1.8.9 (May 15, 2012).

Thank you!

Elena
