Trying to run the example program from the serialib serial communication library.

Library: http://serialib.free.fr/html/files.html

Example Code: http://serialib.free.fr/html/_example1_8cpp_source.html

I compile from the command line with 

g++ Example1.cpp -o example

and get several errors for undefined reference

Example1.cpp:(.text+0x24): undefined reference to `serialib::serialib()'
Example1.cpp:(.text+0x40): undefined reference to `serialib::Open(char const*, unsigned int)'
Example1.cpp:(.text+0x83): undefined reference to `serialib::WriteString(char const*)'

My #include statements find the library .h file, but for some reason it is still throwing this error.

Any ideas why this is happening? I am pretty new at C/C++ and could really use some help.

    it looks like one of two things, 1) the gcc ... line is missing either a) L -lseriallib or b) -I. -I infact, it seems to be missing both sets of parameters. – user3629249 Nov 08 '14 at 09:29
