The installation of DiscoveryStudio 3.5  on nowadays kernel 3.x Linux may not works well and the official site only suggest the kernel2.6 Linux OS including RHEL 4.x 5.x and SLE (SUSElinux entperise)10. However, the kernel 3.X Linux OS improved a lot on speed and it would be nice if DS3.5 could work in nowadays new kernel machine.

For SUSE LINUX ENTERPRISE 11 SP2, it always claimed the following errors when we try to submit jobs:

Server OS: Linux dream 3.0.42-0.7-default #1 SMP Tue Oct 9 11:58:45 UTC 2012 (a8dc443) x86_64 x86_64 x86_64 GNU/Linux

The error message received are caused by a missing system library on linux machine.

The required system libraries for a 64-bit SuSE 11 machine are:

• compat-libstdc++ (x86_64)
• expat-32bit (x86_64)
• fontconfig-32bit (x86_64)
• freetype2-32bit (x86_64)
• glibc-32bit (x86_64)
• libdrm-32bit (x86_64)
• libgcc (x86_64)
• libstdc++ (x86_64)
• Mesa-32bit (x86_64)
• mozilla-nspr-32bit (x86_64)
• pam-32bit (x86_64)
  unixODBC-32bit (x86_64) (by default, this library is not installed)
  
• xorg-x11-libs-32bit (x86_64)
  xorg-x11-Xvfb (x86_64)
• zlib-32bit (x86_64)

 

However if  all the libraries are installed - the libraries require the 32-bit version of the library even on a 64-bit version of Linux - it require the following steps work out:

 rename the <PP installation directory>/linux_bin/libfreetype so that the system libfreetype  is used instead.
