having the same issue currently, anyone figured out a workaround to this issue?
For whatever reason setting the compiler optimization from
-O2 --> -O1
suppresses the error... but you'll still have linker errors in the end.
also.. (while still using -O2) just deleting the line and doing
char extra_info_out[2048];
snprintf(
extra_info_out,
sizeof(extra_info_out),
extra_info
);
allows to compile.. but I'm still getting a segmentation fault..
FWIW ThrowingBagels works out of the box.. only caveat is new packet format.
Ok.. so for the segmentation faults check out here:

Specifically the recommendations as follows:
vi opc-server.c
change e131 port to 0 in
+ .e131_port = 0,
And
+ assert_int_range_inclusive("e131 UDP Port", 0, 65535, input_config-
>e131_port);
make
Geocene has a working version in 4.19: https://github.com/Geocene/LEDscape
I've got a Beaglebone Black running Debian 10.3. When I run 'make' to build the opc-server, it's failing thusly:
opc-server.c: In function ‘opc_server_set_error.part.1’: opc-server.c:211:3: error: invalid use of ‘__builtin_va_arg_pack ()’ snprintf( ^
~~~~ extra_info_out,);
I'm running the stock kernel 4.19.94. GCC is version 8.3.0-6.
There are also a bunch of warnings beforehand. Any suggestions on how to fix this?
