Hi William,

I have made some further changes that allow for compiling the example IOC - please try again and let me know if that works.

Best,

thanks for fixing the support module,

now I can compile it.

but I struggle to get the example app compiled...

I have applied and pushed the patch, and can now build OK with modbus R3-2:

Hi Jakub ,

 

Ø  I was planning on getting it working with the newer modbus version at some point, which it seems you have already done, perhaps we should just apply those changes to the repo?

 

That sounds good.  Are you OK with just applying my changes using the “patch” command, or do you want me to fork the repository and make a PR? 

 

One thing you need to do before applying the patch is to do:

 

git mv eurothermModbus.c eurothermModbus.cpp

 

Mark

Hi Mark,

 

This repo is a backup of an IOC instance we had running that as far as I could tell had no upstream master (I believe it was downloaded as a source tarball, probably from the DLS site). I was planning on getting it working with the newer modbus version at some point, which it seems you have already done, perhaps we should just apply those changes to the repo?

 

Best,

Jakub

I now realize that DLS repository is not the same as the one you are using.  However, this one does seem to be the same:

 

https://github.com/jwlodek/eurotherm2k

 

Jakub, is this repository a fork of a master somewhere else, or is this now the primary repository?

 

Mark

Hi William,

 

It appears that the eurothemModbus source code is on Github here:

 

https://github.com/dls-controls/eurothermModbus

 

Does your gitlab dump differ from that?

Hi Mark,

 

unfortunately, it doesnt work, various casts fail.

 

I've saved a dump here: https://gitlab.fhi.mpg.de/kw/eurotherm2k

(should be externally accessible)

Hi William,

 

You can probably just rename eurothermModbus.c to eurothermModbus.cpp.  See if that works.

 

How does eurothermModbus use drvModbusAsyn?

Hi,

unfortunately the DLS site for the eurotherm support module is not available anymore...
(http://controls.diamond.ac.uk/downloads/support/eurotherm2k/)

does anybody still maintain eurotherms?

I kinda converted the 1-22 release to work with my environment and am now running into a C / C++ error...
newer asyn versions reference vector.h which is C++ while my eurotherm support file is C, which is bad because the C compiler doesnt know about the C++ vector.h ...

In file included from /home/epics/EPICS/epics-support/modbus/include/drvModbusAsyn.h:15,
                 from ../eurothermModbus.c:25:
/home/epics/EPICS/epics-support/asyn/include/asynPortDriver.h:4:10: fatal error: vector: No such file or directory
 #include <vector>
          ^~~~~~~~
compilation terminated.

Im not sure how to get around this....

maybe someone with more experience in the EPICS build system can help me out.

thanks,

William
