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

[Heinz Junkes via Tech-talk <tech-talk at aps.anl.gov>]

i have now added the following in epics-base 
to configure/os/CONFIG_SITE.Common.linux-ppc64e6500:

OP_SYS_INCLUDES += -I$(SDKTARGETSYSROOT)/usr/include/tirpc
OP_SYS_LDLIBS += -ltirpc
