I had the same problem on RHEL8 recently. It was reported here: https://github.com/epics-modules/asyn/issues/95 

If "TIRPC=YES" does not work for your cross compile, then you probably need to comment out all vxi11-related stuff in asyn/asyn/Makefile

Good luck!

    Hi,

    I think I came across the same issue recently on RHEL8. There was a recent Asyn build option added, that you can set in CONFIG_SITE (or CONFIG_SITE.local):

    TIRPC=YES

    Which changes the include file search path to /usr/include/tirpc/

    Cheers,
    Matt

    Subject: [EXTERNAL] asyn vxi11 rpc issue cross compile for yocto powerpc64-fsl-linux

    I am in the process of cross-compiling EPICS7 for powerpc64-fsl-linux.

    epics-base works great, also already some support-modules like sncseq, sscan, calc, busy …

    Now I just fail with asyn on the vxi11 part.

    rpc/rpc.h can only be found on the yocto-sysroot under usr/include/tirpc. Also I don't see any rpc-support like rpcgen etc..

    That may also be due to how it was built with yocto. But this part I have not yet understood and I use 
    recipes from ESS and am quite happy where I have now arrived with their help ;-)

    Is there a variable/flag I can use to keep the vxi11 stuff out of the build process of asyn?
