mcaCanberra, mcaAIM, and nmcDemo are built unconditionally on OS X

[kmpeters]

mcaApp/CanberraSrc/Makefile allows mcaCamberra, mcaAIM, and nmcDemo to be easily omitted from the build on Linux:

# Linux
# To build for Linux system uncomment the following lines.  This requires libnet or
# LLC sockets
ifeq ($(LINUX_NET_INSTALLED), YES)
LIBRARY_IOC_Linux += mcaCanberra
PROD_IOC_Linux    += mcaAIM
PROD_IOC_Linux    += nmcDemo
endif

But not on OS X (Darwin):

# Darwin
LIBRARY_IOC_Darwin          += mcaCanberra
PROD_IOC_Darwin             += mcaAIM
PROD_IOC_Darwin             += nmcDemo

I don't know if the correct approach is to add DARWIN_NET_INSTALLED to mca's configure/CONFIG_APP or to change LINUX_NET_INSTALLED to something more general that applies to both Linux and OS X.

OS X builds are broken if libnet isn't installed:

cc -c            -DUSE_LIBNET -g `libnet-config --defines`     -DUNIX  -Ddarwin     -O3 -g   -Wall     -DUSE_LIBNET -g `libnet-config --defines`    -arch x86_64    -fno-common -fPIC -MMD -I. -I../O.Common -I. -I.. -I../../../include/os/Darwin -I../../../include    -I/Users/kpetersn/synApps_testing/3.14/synApps/support/calc/include  -I/Users/kpetersn/synApps_testing/3.14/synApps/support/sscan/include  -I/Users/kpetersn/synApps_testing/3.14/synApps/support/busy/include  -I/Users/kpetersn/synApps_testing/3.14/synApps/support/std/include  -I/Users/kpetersn/synApps_testing/3.14/synApps/support/seq-2-2-3/include -I/Users/kpetersn/synApps_testing/3.14/synApps/support/autosave/include/os/Darwin -I/Users/kpetersn/synApps_testing/3.14/synApps/support/autosave/include  -I/Users/kpetersn/synApps_testing/3.14/synApps/support/asyn/include  -I/Users/kpetersn/synApps_testing/3.14/synApps/support/mca/include -I/Users/kpetersn/synApps_testing/3.14/base-3.14.12.5/include/os/Darwin -I/Users/kpetersn/synApps_testing/3.14/base-3.14.12.5/include        ../nmc_comm_subs_1.c

I would suggest changing LINUX_NET_INSTALLED to LIBNET_INSTALLED or better HAVE_LIBNET, which is the syntax that many packages use.

[kmpeters]

I will change it to HAVE_LIBNET and create a pull request.

• Do we have that option in the master branch?
• After installing libnet on OS X through brew, makefile still cannot find libnet.h. The following trick works

USR_CFLAGS_Darwin           += -g `libnet-config --defines --cflags`
USR_CPPFLAGS_Darwin         += -g `libnet-config --defines --cflags`
USR_LDFLAGS_Darwin         += `libnet-config --libs`
mcaCanberra_SYS_LIBS_Darwin += pcap
mcaAIM_SYS_LIBS_Darwin      += pcap
nmcDemo_SYS_LIBS_Darwin     += pcap
