Hi Brandon,

 

On CentOS 7 you don’t need tirpc, just use the standard glibc-headers packages which installs /usr/include/rpc/rpc.h.  Does that file exist on your system? I have used many versions of CentOS7 and that file has always been present.

 

You should not uncomment this line in asyn/configure/CONFIG_SITE

# TIRPC=YES

 

And you should not change any Makefiles.

 

Please go back to the distributed version of asyn, make sure the glibc-headers package is installed.  If you still get an error building please send the complete output of make when building asyn.

 

Mark

Subject: Issue installing asyn on CentOS 7

 

Hello,

 

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:

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)

    USR_INCLUDES_Linux += -I/usr/include/tirpc
    asyn_SYS_LIBS_Linux += tirpc
  endif

 

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
