Re: Issue installing StreamDevice on CentOS 7

Hi Brandon,

My example, my asyn has a dependency on CALC; that is the reason you see.

If you don't know or don't need CALC,  you can ignore that.

If your Asyn has more dependencies on whatever modules, you can similarly define them.

Thank you for the reply! I am not 100% sure what CALC is -- using find, I see a folder .../epics-base/modules/libcom/src/calc/ but it does not seem to contain the header files that make needs (sCalcoutRecord.h, for example). 

It seems like I need to install the full SynApps package to obtain Calc? I currently have asyn, is that just one component of SynApps? 

It always depends on what you need. If you don't know, I recommend installing the full SynApps first. For me, I install one by one according to what I need. I don't use SynApps.

 

The tutorial I was following had me execute makeBaseApp.pl -t support prior to cloning the StreamDevice git repo, for a reason that I don't really understand. Do I need to do that with the method you've described?

The tutorial is the last step; you have all EPICS bases and modules in your system before going there.

And each IOC and module generated by "makeBaseApp.pl" should have the same rule in their configuration in configure directory.

Key files you have to understand in configure are

- RELEASE

- CONFIG_SITE

And *.local allows you to add your environment without changing an original git history in each repo.

Best,

Han

 

Thank you,
Brandon

Hi Again,

StreamDevice from https://github.com/paulscherrerinstitute/StreamDevice

0. install re2c package

1. rm -f  GNUmakefile

2. echo "EPICS_BASE=your_epics_base"                              > configure/RELEASE.local

3. echo ASYN=$(INSTALL_LOCATION_ASYN)"                    >>  configure/RELEASE.local
   echo "CALC=$(INSTALL_LOCATION_CALC)"                    >> configure/RELEASE.local
   echo "PCRE="                                                                      >> configure/RELEASE.local
   echo "CHECK_RELEASE = NO"                                           > configure/CONFIG_SITE.local

   sed -i -e "/^CHECK_RELEASE/d"     configure/Makefile

4. make

HTH,

Han

Hello Brandon,

EPICS modules are made aware about the location of other files they must include or link against through the use of the configure/RELEASE file. In StreamDevice, the configure/RELEASE file has the following line:

EPICS_BASE=/usr/local/epics/base-7.0.3

Thus, when you build, the module will try to find certain makefile rules, config files, headers, and libraries it needs in /usr/local/epics/base-7.0.3

When you are adding in a new module, you have to edit the configure/RELEASE file to match up the named macros with the locations where epics-base or the given modules are located on your system.

Subject: Issue installing StreamDevice on CentOS 7

 

Hello,

I am encountering an issue when attempting to install StreamDevice on our CentOS 7.9.2009 machine using this tutorial (step 7): https://epics-controls.org/resources-and-support/documents/getting-started/

When I run make from ~/EPICS/support/stream/StreamDevice, I get these errors:

$ make
configure/CONFIG:18: /usr/local/epics/base-7.0.3/configure/CONFIG: No such file or directory
Makefile:33: /usr/local/epics/base-7.0.3/configure/RULES_TOP: No such file or directory
make: *** No rule to make target `/usr/local/epics/base-7.0.3/configure/RULES_TOP'.  Stop.

Am I supposed to have an epics directory in /usr/local? I am unsure if this is an issue with setting paths correctly or an issue with my epics base install as I do not seem to see anything with the directory structure .../epics/base-7.0.3/...

Thank you,
Brandon
