Re: [pcp] PCP build on CentOS 6.6 - VirtualBox 4.3.26

[Paul Colby <pcp@xxxxxxxxxxx>]

You might need to run `ldconfig` (not sure if `make install` is doing that for you).

See: man ldconfig

Cheers.

I am researching PCP (and friends) as a replacement for Orca/SE Toolkit.

[this morning, sometime after 8 AM CDT]
I created a virtual machine using:
VirtualBox 4.3.26-r98988 on Windows 7 Enterprise SP1
and the
CentOS-6.6-x86_64-bin-DVD1.iso (selected "Basic Server")

The VM was updated using:
# yum update

At this point I created a Forwarding rule and switched to PuTTY.

I created a user account (and group):
# useradd -K PASS_MAX_DAYS=-1 -f -1 -e ""Â -c "for Performance Co-Pilot"Â pcp

added the following:

# yum install git
# yum install gcc
# yum install bison
# yum install flex
# yum install gcc-c++
# yum install qt-devel-4.6.2-28.el6_5.x86_64

switched to user pcp and
$ git clone git://git.pcp.io/pcp
$ cd pcp
$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var

 Â(Note: configure produced the following warning but otherwise I see no complaints - I ignored the warning)
WARNING: Python version 2.6 header file missing.
Cannot proceed with the Python 2 installation found.

$ make

$ su root
# make install

# chkconfig pmcd on
# service pmcd start

It failed with the following output:


[root@CentOS66BasicServer ~]# chkconfig pmcd on

I have very little experience with Linux but have been working with Solaris for the last 10 years. The symbolic links look iffy to me.

I hope this is something simple that I overlooked or missed in the docs.

Is CentOS a good environment for experimenting with PCP and friends?


Thanks for any advice,
Glen Gunselman
