Installation of pacemaker pcs

[aaroentr]

We are working on making a high availability cluster of two IC-3120 which run our Labview-software.
We want to do this using pacemaker and pcs.

Pacemaker is installed from source using this guide:

https://github.com/ClusterLabs/pacemaker/blob/master/INSTALL.md

We are then trying to install pcs from source using this guide:
https://github.com/ClusterLabs/pcs

Here we get the following error (snippet from console output):

Has anyone seen something similar?
Is it the C-compiler which is not properly set up?

Hi aaroentr,

You'll need to interpret the error logs and compiler settings. The one thing that jumps out at me is this: 

"x86_64-nilrt-linux-gcc  -m64 -march=core2 -mtune=core2 -msse3 -mfpmath=sse --sysroot=/srv/jenkins/perforce/ThirdPartyExports/NIOpenEmbedded/trunk/6.5/objec$
In file included from /usr/include/ruby-2.4.0/ruby/ruby.h:36:0,
                 from /usr/include/ruby-2.4.0/ruby.h:33,
                 from conftest.c:1:
/usr/include/ruby-2.4.0/ruby/defines.h:101:19: fatal error: stdio.h: No such file or directory
 #include <stdio.h>

 It looks like you're not finding the stdio.h header file. That header should be located in the /usr/include directory. 

One potential problem I see is that your gcc command has a sysroot that shouldn't be required if you're compiling on the target. How are you generating the makefile? Where are you getting that sysroot flag from? What version of LabVIEW Real-Time is installed on the target?

Hi GatorBait

Thanks for your reply.

I have found stdio.h in /usr/include.

The makefile is not generated by me. It is included in the .tar.gz from the github repo.

I am not familiar with the sysroot flag. Should I be able to diable this and hopefully advance further?

The target has NI Linux Real-Time version 6.0.
