C files being ignored? [message #1290689] Thu, 10 April 2014 10:44 Go to next message

I have a C project in eclipse using the GNU build tools.
It started with a single .c file and I want to add another c/h file pair to keep parts of the code in separate files. Pretty normal stuff.

I have added a new .c file and .h file using the "file / new / Source File" and "file / New / Header" file menus.
I have populated the files as usual.

I have #included the new header file in the main C file.

The contents of the header are processed, I know because some of my #DEFINEs are present.
But the implementation of the functions in the new C files are not found.

When I build I get:
/home/user/workspace/mercury/src/mercury.c:70: undefined reference to `becomeDaemon'

But the method 'becomeDaemon' is correctly define in the new .h file, and correctly implemented in the new .c file.

Further, I can put any syntax errors I wish in the new .c file and they are ignored, and do not flag as errors.

So it looks like the build tools are ignoring my new source file?

How do I tell the build tools to include the new source file?
I have attached a screen shot of Eclipse, showing the original source, the new files and the errors.

Any suggestions?

I suggest you convert the project to use a Makefile. It is much easier to control Makefile project - you have full control, you can define dependencies, configure steps to perform (aka Makefile targets) etc.

You'd need to add a simple Makefile to the source directory and make sure you can perform a build by running "make". Then you can import your source tree into Eclipse as "File -> new project with existing makefile".
