MP3 example code compilation error

[calixarene]

I got error messages when I tried to compile example code from the accompany CD of the mikromedia dspic33 board and the latest example code from mikroe web site with both mikroBasicPRO ver 5.2 and 5.6. Here are the error messages output .

************************************

What is the possible cause and how to fix it? I am using the dongle version.

By the way, what is the meaning of the warning message"Warning: Source size (XX) does not match destination size (XX) MP3.mbas". When I click on the error it leads me to line started with UART2.

Thanks.

Hi,

Judging by this, I suspect that the String library isn't included in the Library Manager.
Please, include it and see if the project can be compiled now.

As for the warnings, they show that the string which are manipulated haven't got the same size, i.e. copying the smaller string to a larger string.

Regards,
Filip.

Thanks. The error disappear when I include the string library.

I am a newbie to this compiler.

Is there any difference/short coming between enabling all libraries during compilation as suggested in the "Creating the first project in... " manual and enabling only the libraries necessary for the project?

Hi,

The difference may lay in the compilation time; with all libraries included the compilation time could be slightly longer.
As for the memory usage there is no difference.

Filip.
