Re: [building EPICS in RHEL-5 64bit] environment variables

[Pavel Masloff <pavel.masloff@gmail.com>]

THANKS MIROSLAV!!!

It worked. The base is installed now at long last. Any idea on how to use EPICS? I started with softIoc and then iocInit. Which were both ok. After that i run exit. I am planning to hook up a Tektronix 3054 oscillograph. But hesitate for some reason. Do not know where to start.

Thank you very much! You helped a lot!

Hello.
I am new to epics as well but maybe I can save you some of the troubles I went
trough during the installation on linux .
These are my personal notes for the EPICS installation.

 In general for linux you need to setup the EPICS environment variables.
One way of doing that is via the file ~/.bashrc

Here is the content of my bashrc file.
------------------------------------------------------------------
EPICS_HOST_ARCH=linux-x86_64
EPICS_BASE$HOME/EPICS/BASE
EPICS_DISPLAY_PATH=$HOME/EPICS/synApps/support/all_adl/
LD_LIBRARY_PATH=$HOME/EPICS/BASE/lib/linux-x86_64
PATH=$PATH:$HOME/bin:$HOME/EPICS/BASE/bin/linux-x86_64:
$HOME/EPICS/extensions/bin/linux-x86_64/:/usr/local/bin
I could  help you with the epics installation for the redhat.
export EPICS_HOST_ARCH
export EPICS_BASE
export PATH
export EPICS_DISPLAY_PATH
export LD_LIBRARY_PATH

------------------------------------------------
For BASE you will need those  packages.

 yum install perl-devel readline-devel gcc-c++
Also for RedHat 5 you need to use the ncurses instead of the readline libraly.
So in the file
~/EPICS/BASE/configure/os/CONFIG_SITE.Common.linux-x86 or
CONFIG_SITE.Common.linux-x86_64
comment the line refering  to readline and uncoment the ncurses.
--------------------------------------------------------------------------------



# No other libraries needed (recent Fedora, Ubuntu etc.):
#COMMANDLINE_LIBRARY = READLINE

# Needs -lncurses (RHEL 5 etc.):
COMMANDLINE_LIBRARY = READLINE_NCURSES
--------------------------------------------------------------------------------

Don't forget to run
make clean
before
make install

Also don't forget that the changes made to bashrc do not take in effect until
the next login.
Let me know if this worked for you.
