Would folks offer suggestions on my linking problem?
« on: April 25, 2014, 01:58:18 am »
I can build simple programs just fine.  When I incorporate libraries, then it appears that stdint.h is not being loaded.  I base this on the apparent lack of a definition for the datatype uint8_t

The myriad of settings, coupled with my limited C knowledge, leaves me struggling to sort out my problem.  Yes, I am quite sure it is MY problem, not Code::Blocks. 

I just need some suggestions on how to divide and conquer this problem.  I am lost when it comes to a strategy for narrowing it down.

Code: [Select]

People are probably going to go down the 'show us your code' path.  But if we can stay on the path of how to sort through all the compile and link options, search paths, defines and so on, I figure I can sort it out.  What's my best angle of attack to sift through all those variables to zero in on the cause?  So far, it's been hours of 'well I guess I'll try setting/changing this' all over and rather scattershot at that.

With that, the bottom line is a Class that defines two uint8_t parameters in its constructor are flagged in the error output as 'char' data types, which it rightly concludes does not match the Class definition.

How does C::B (well, really the compiler I suppose) arrive at a char data type?  Is that a last-ditch 'I didn't find anything else so I'll call it a char' outcome?  Again, I figure that maybe stidint.h, where uint8_t is defined, is not being included.  Which leaves the basic questions: Why? and Where should I look to answer that?

Thanks in advance.

So, insight into how CodeBlocks works and ultimately selects the options it runs a compiler with from the myriad of property sheets is out of the question?

First enable full logging in the settings of the compiler.
Second check if you have the cpp file containing the RF24 method implementation into the project.
Please re/read the link posted by stahta01...

For an explanation for how C::B passes options to the compiler you'll need to check the user manual.
