Hi everyone,
Here at the Spallation Neutron Source (SNS) we have a need to build
our EPICS vxWorks target on Linux platforms.
Currently we are supporting the following Hosts:
x86 --- Red Hat Linux 7.0
x86 --- Red Hat Linux 7.1
x86 --- Red Hat Linux 7.2
Currently we are supporting the following targets:
vxWorks 5.4.2 --- MVME2101
vxWorks 5.4.2 --- MVME2302 (still in progress)
vxWorks 5.4 --- MVME167 (only in old "test-stands")
------------------------------------------------------------------------------------
Andrew Johnson (at Argonne National Labs) and Jeff Hill (LANL) suggested that
we request the GNU source for cross-compiling from Windriver Systems (WRS).
We will then be able to port the Tool-Chain to Linux.
So, we requested the Windriver GNU toolchain source code CD.
The WRS Part No: TDK-12878-ZC, CD Title: Tornado 2.0 GNU Source
The CD is "free" if you have a valid WRS license; just request
from local WRS Sales Rep.
The above approach is recommended to ensure compatability with the vxWorks
libraries.
We tried to use the newer gcc-2.95.X compilers on our own with limited
success in EPICS R3.13.X. However, when we moved to EPICS R3.14.0beta1 the
"underground" approach no longer worked for us.
EPICS R3.14.0beta1 introduced a lot of C++ code in the EPICS and Channel
Access code. Basically our EPICS IOCs went "belly-up"
-----------------------------------------------------------------------------------------
We have tested the new compiler mainly with the PPC603 EPICS IOCs.
Please provide any comments/feedback.
How to get and build the cross-compiler from the SNS Project?
Get the "source-code" gzip'd distribution from our public ftp site:
ftp://snsftp.sns.ornl.gov/UPLOAD/controls/CROSS
SNS collaborators can access the distribution via CVS {cvsroot/t202/host/src}
There will be a README file there for the build instructions.
For technical difficulties send e-mail to Dave Thompson or Ernest Williams.
Thanks,
