Compiling EPICS and Building IOC Applications on Tru64Unix/Alpha
|
|
(former Digital-Unix, and even former OSF1)
|
|
for architectures "osf-alpha" and "osf-alpha-gnu"
|
|
|
|
======================================================================
|
|
|
|
Tools needed
|
|
------------
|
|
|
|
For C/C++ Compiler, you need one of these compiler set.
|
|
|
|
- DEC/Compaq/HP's ANSI C/C++ compilers for "osf-alpha"
|
|
I used
|
|
cc -V
|
|
Compaq C V6.5-303 (dtk) on Compaq Tru64 UNIX V5.1B (Rev. 2650)
|
|
Compiler Driver V6.5-302 (dtk) cc Driver
|
|
cxx -V
|
|
Compaq C++ V6.5-042 for Compaq Tru64 UNIX V5.1B (Rev. 2650)
|
|
Compiler Driver V6.5-042 (cxx) cxx Driver
|
|
|
|
- GNU gcc/g++ compiler for "osf-alpha-gnu"
|
|
I used
|
|
gcc --version
|
|
gcc (GCC) 3.4.3
|
|
|
|
Environment
|
|
-----------
|
|
|
|
Before compiling, please set the environment variable EPICS_HOST_ARCH
|
|
dependent on your compiler.
|
|
|
|
for cc/cxx
|
|
setenv EPICS_HOST_ARCH osf-alpha
|
|
(setenv EPICS_HOST_ARCH `startup/EpicsHostArch.pl`)
|
|
export EPICS_HOST_ARCH=osf-alpha
|
|
|
|
for gcc/g++
|
|
setenv EPICS_HOST_ARCH osf-alpha-gnu
|
|
(setenv EPICS_HOST_ARCH `startup/EpicsHostArch.pl gnu`)
|
|
export EPICS_HOST_ARCH=osf-alpha-gnu
|
|
|
|
Building
|
|
--------
|
|
|
|
Should be quite straightforward. Edit (if necessary) the CONFIG_SITE
|
|
files and "make". (Be sure that GNU make is in your path or call it
|
|
explicitly as the standard make on Tru64Unix is _not_ GNU.)
|
|
|
|
For example (with csh):
|
|
setenv EPICS_HOST_ARCH `startup/EpicsHostArch.pl`
|
|
make |& tee ../make-base-osf.log
|
|
make runtests | & tee ../test-base-osf.log
|
|
setenv EPICS_HOST_ARCH `startup/EpicsHostArch.pl gnu`
|
|
make |& tee ../make-base-osfgnu.log
|
|
|
|
Minor errors are detected in and timer. They should be investigated
|
|
later.
|
|
|
|
Some internals
|
|
-----------------------
|
|
|
|
__alpha is used to distinguish this architecture from others.
|
|
__DECCXX is used to distinguish DEC/Compaq/HP C++ compiler from GNU's.
|
|
There are several ways to specify compiler options for pthread.
|
|
Please consult the pthread(3) manual page.
|
|
src/libCom/osi/os/osf is used for osi definitions,
|
|
src/libCom/osi/os/alpha is not used.
|
|
About 230 warning messages with cc/cxx, and 4 with gcc. Sometimes
|
|
errors from cxx are intuitive.
|
|
I just started to use IOC application for a gateway purpose. There
|
|
can be architecture-dependent problems, that I didn't find yet.
|
|
|
|
Only several lines in configure and src files were modified from
|
|
base-3.14.4/5/6/7/8/8.2/9pre. Thanks the core team for keeping
|
|
the alpha-osf dependent part in the distribution.
