Cilkview Cilkscreen Centos 7

Charles_Tolle · ‎07-20-2015

Issues with Cilktools. I have compiled and installed gcc 4.9 and gcc 5.2 on Centos 7 and installed them. The fib.c test code runs fine for both gcc's.

However when I attempt to use the cilktools provided on:

https://www.cilkplus.org/download

I get the following error:

./cilkview: error while loading shared libraries: libstdc++.so.6: wrong ELF class: ELFCLASS64

I believe this is a 32bit lib issue but how can it be over come. I saw some links discussing this in 2012... Nothing since. Is there an updated source code that can be recompiled? Or is there a 64bit version. The tools would be very helpful I am thinking about using Cilk Plus this fall in a class but I need the tools to be working! The cilkplus org webpages have not been updated since 2013...

Thank you for your help,

Hi,

It looks like your system does not have 32-bit libstdc++.

Can you try it again after installing the packaage, "libstdc++.i686" ?

# yum install libstdc++.i686

By the way, the instrumentation support for Cilk tools is not implemented in gcc 4.9 or later, so you will have to use the GCC branch, "cilkplus-4_8-branch" for now. Alternatively, there is a program that offers free software to educators, where you can find Intel compilers - https://software.intel.com/en-us/qualify-for-free-software/educator.
