Compiling EPICS on WIN32 (Windows95/NT)

|
Original port of EPICS base to WIN32 (Windows95/NT)

0) what you will get
|
|
--------------------
|
|
|
|
Right now this port of EPICS to WIN32 should allow you to
|
|
|
|
* compile almost all of EPICS base using {Tornado, MS Visual C, perl,
|
|
GNU make} (only {MS Visual C, perl, GNU make} if you prefer
|
|
to compile only the host portions of EPICS base).
|
|
* load EPICS on a PC IOC (486, pentium),
|
|
load simple databases
|
|
(no drivers/devices for real I/O available, yet.
|
|
Some Greenspring IP support [Relay, Dig, ADC, DAC] is in progress)
|
|
* build and use ca.dll on NT or Win95 to access all IOCs,
|
|
as well as the Com-library, gdd-library, and cas-library as DLLs.
|
|
The remaining libraries are statically linked and
|
|
therefore only accessible from programming languages like C,
|
|
not general WIN32 apps.
|
|
* build gdd, cas and a demo of the new portable CA server on WIN32.
|
|
|
|
1) see what you have
|
|
--------------------
|
|
|
|
To compiler EPICS on WIN32, we need
|
|
|
|
WindRiver System's Tornado (used: 1.0) (not required if host only build)
|
|
Microsoft's Visual C/C++ (used: 4.0) (borland C++ rumored to work also)
|
|
|
|
and some tools:
|
|
|
|
gnu make www.gnu.org
|
|
perl www.perl.org (used 5.003)
|
|
|
|
The perl interpreter and gnu make are available 'on the net'
|
|
as sources which compile with MS Visual C++.
|
|
If you cannot/don't want to find them, contact me, please!
|
|
|
|
2) set environment variables
|
|
|
|
Your path should include:
|
|
- The EPICS-binaries that we are about to build in <EPICS>base/bin/WIN32
|
|
- The System (for me it's in NT40...)
|
|
- The MS Visual C compiler binaries
|
|
|
|
Check with e.g.:
|
|
|
|
>echo %Path%
|
|
C:\WINNT35.0\system32;
|
|
C:\WINNT35.0;
|
|
c:\msdev\bin;
|
|
c:\perl5\bin;
|
|
c:\make-3.75\WinRel;
|
|
c:\epics\base\bin\win32 (really where INSTALL_LOCATION specifies)
|
|
|
|
On NT, "Path" is defined by the operatin system, on Win95, it's "PATH" instead.
|
|
|
|
MS Visual C and Tornado should be installed properly with
|
|
these env. variables set:
|
|
|
|
WIND_BASE=c:\Tornado (required for cross development only)
|
|
WIND_HOST_TYPE=x86-win32 (required for cross development only)
|
|
|
|
This way the EPICS makesystem can locate Tornado
|
|
without any changes to the files in base/config.
|
|
So for pc486 the settings in CONFIG_SITE where
|
|
you specify the location of VxWorks are ignored,
|
|
this information is taken from WIND_BASE and _HOST_TYPE!!
|
|
|
|
MSDevDir=C:\MSDEV
|
|
include=c:\msdev\include;c:\msdev\mfc\include
|
|
lib=c:\msdev\lib;c:\msdev\mfc\lib
|
|
|
|
Select host arch to build:
|
|
HOST_ARCH=WIN32 (used by the make system)
|
|
|
|
Special note: configuring EPICS_CA_AUTO_CA_ADDR_LIST under WIN32
|
|
----------------------------------------------------------------
|
|
Currently if EPICS_CA_AUTO_CA_ADDR_LIST is YES (the default)
|
|
then the ca address list will be initialized to the broadcast address of
|
|
one of the interfaces on the WIN32 host (in the near future this will be
|
|
fixed so that the broadcast addresses of all interfaces is used as on other os).
|
|
If EPICS_CA_AUTO_CA_ADDR_LIST is NO behavior is as described in the CA
|
|
reference manual.
|
|
|
|
(Setting env. vars. is different: for NT, use Settings/System,
|
|
for Win95 use autoexec.bat)
|
|
|
|
3) building EPICS
|
|
-----------------
|
|
|
|
Prepare apx. 2 ltr. Tee and type:
|
|
|
|
cd <epics>/base
|
|
make (use gnu make)
|
|
|
|
Watch for errors and send them to me.
|
|
|
|
Known problems:
|
|
* gnumake seems to be faster than WIN32 sometimes
|
|
which results in warnings/errors like
|
|
"file has modification date in the future"
|
|
for newly vreated things.
|
|
Very seldom this is fatal, so you have to
|
|
stop gnumake and restart it.
|
|
* This is strange because Windows95/NT don't care
|
|
about upper/lower case:
|
|
WIN32 is WIN32, not win32. Gnumake fails
|
|
if e.g. base/src/include/os/WIN32 is ...win32.
|
|
|
|
Good luck !
