Hi Pierrick,
Where in your configure/CONFIG_SITE files are you setting TIRPC=YES?
There are 2 places in Asyn where GnuMake looks at the TIRPC variable. Both asyn/Makefile and testGpibApp/src/Makefile do this:
# Some linux systems moved RPC related symbols to libtirpc
# Define TIRPC in configure/CONFIG_SITE in this case
ifeq ($(TIRPC),YES)
USR_INCLUDES_Linux += -I/usr/include/tirpc
asyn_SYS_LIBS_Linux += tirpc
endif
For cross-compilation you really don’t want that to be enabled in either Makefile, so if you’re setting TIRPC=YES in your onfigure/CONFIG_SITE file you also need to set TIRPC=NO in your
CONFIG_SITE.Common.linux-arm_raspberrypi5 file. Alternatively only set it to YES in the target-specific CONFIG_SITE.Common.$(T_A) files where those are needed.
HTH,

I guess that my real question is, how does one turn "off" the
