I get undefined reference to serial::list_ports()'` when i try to use the example file.
the error is thrown in this line https://github.com/wjwwood/serial/blob/master/examples/serial_example.cc#L49

vector<serial::PortInfo> devices_found = serial::list_ports();

I can compile example locally on my Mac and the definition for that function is in the serial/serial.h header:

https://github.com/wjwwood/serial/blob/master/include/serial/serial.h#L734

Can you give more info on how you are building this?

@ejb1123 that looks like a successful build to me 😄

You can try make test to make sure stuff builds and run against it.

That looks like a success to me too, maybe you had an old version of the serial library lying around and when you compile it found the new header, but when you tried to link you got the old version of the library.

Either was I don't see any issue with the output you posted above.

Thanks for the help i got it working in code blocks.
I had to set the the linker setting by pointing it to /usr/local/lib/libserial.so
