Experimental Physics and
Industrial Control System

I have encountered another issue while trying to get EPICS installed on our CentOS 7 machine.

Based on similar posts in the mailing list, it seems to be TIRCP related. Here is the error I get when I try to make:

$ make

Things I have tried:

1) In configure/CONFIG_SITE, I uncommented the line:

TIRPC=YES

2) In asyn/Makefile, I appended this to the very end:

 ifeq ($(TIRPC),YES)

3) I removed the empty header files from /usr/include/rpc and replaced them with symbolic links pointing at  the files in /usr/include/tirpc/rpc

Unfortunately, nothing seems to have any effect on the error generated from make and that seems to have exhausted all solutions I could find in the archives. Any ideas about how to fix this?

P.S.: This machine controls our diffractometer and we are just trying to get spec to talk to our Lakeshore 336  -- both asyn and StreamDevice are necessary for this purpose?

Thank you,
Brandon
