Problems building C++ code using a Serial library

(1/4) > >>

PaulUK:
Dear All,

First post here.  I'm quite new to CodeBlocks and working on a wxWidgets based GUI that uses serial coms to talk to an external device.

I got the program to work (using Windows 7) when using CreateFile to setup the serial port.  Now I'd like to use a library found here:
https://www.codeproject.com/Articles/992/Serial-library-for-C

I put the serial.cpp and serial.h files in the project folder but when I go to build, I get the following error.

undefined reference to 'CSerial::Open(......)

This is the function that is supposed to open a serial port.  Has anyone else had issues with this library in CodeBlocks?  It was initially used with MS VS circa 2003.  I have included serial.h at the top of the main program file.  Thank you.

Did you add serial.cpp to the CB project? If not, try doing so.

If you do not wish to add serial.cpp to the CB project; then, you need to build the library and link to it.

Hello Tim,
Yes, I added the serial.cpp and .h files to the project and they appear in the sources and headers tree. 

PaulUK:
I am running Code::Blocks version 20.03 on Windows 7. The compiler I use is GCC default (don't know which version number).

Hope this helps.
