Hi all,
I just downloaded the latest iotivity release by git cloning it, and I'm trying
to run a build.
The build fails with the following error:
resource/csdk/security/src/ocsecurity.c:75:16: error: this statement may fall
through [-Werror=implicit-fallthrough=]
prefix = (isSecure == true) ? COAPS_TCP_PREFIX : COAP_TCP_PREFIX;
resource/csdk/security/src/ocsecurity.c:77:5: note: here
case CT_ADAPTER_IP:
^~~~
Looking in the code, the fallthrough is intentional, but it appears that the
build system is setup to
consider such things an error. I introduced a temporary fix by adding:
__attribute__ ((fallthrough));
Now the new errors are:

cc1: all warnings being treated as errors
I'm invoking the build by simply running `scons` in the root directory.
I'm building on Ubuntu 17.10. My compiler is gcc 7.2.0.
Are there some build settings I need to set up for it to build correctly?
Regards,
Nikita Kiryanov
