[Difx-users] Problem in installation of DiFX

[Lupin Lin]

To whom will concern it,

Sorry to spend your time on some simple question about the installation of DiFX.

1. Is the most stable ver. of DiFX 2.4.1?
In Geoff Crew’s mail, he mentioned that DiFX 2.4.2/3 is rolled into DIFX-2.4 as agreed 2014 DIFX meeting.
So I supposed that the most updated(also stable??) version is 2.4.
Do I misunderstand anything?

2. I downloaded the IPP from the official site.
https://software.intel.com/en-us/articles/free_ipp <https://software.intel.com/en-us/articles/free_ipp>

The latest IPP ver. is 2017
However, when I perform "/genipppc $IPPROOT  ($IPPROOT is the directory of installed IPP), I received the following message.
####################################################################
Reading version from /opt/intel/compilers_and_libraries_2017/linux_ipp/include_ippversion.h
Get version 2017.0.0
Note: DIFXITS was not set - used platform.architecture to determine that bits is 64
platform = linux2
ipparch = 64
Sorry, IPP 2017 not yet supported by this script
##################################################################
It seems the genipppc of DiFX-2.4 cannot support IPP ver. 2017 to generate the installation links inside the file “IPP.PC”.
I tried to install an old IPP version, but it does not support for my OS (Ubuntu 16.04 LTS).

Is there any updated script of “genipppc” to support for the latest IPP package?

Sincerely,
