Meaningful compiler error messages

I spend an inordinate amount trying to understand the garbled error messages from the GNU C++ compiler that comes with Visual Micro / Arduino. Are there any alternatives that will produce better diagnostics (Clang?) and how difficult is it to install an alternative compiler?

The toolchain is specified by the core you have chosen

Tim,

Your message is too cryptic for me to understand. Could you please add a few sentences and possibly a link or two that will give me some more context.

Thanks,

Bob

You have not given info about which board you are using so I could not be more specific.

The fact is that when you install the arduino ide or download using board manager you are installing a core (platform). That contains the tools to build the code and instructions of what programs to run to perform the build.

So when you decide which board you want to use and you decide to use an arduino or compatible board you are choosing the toolchain which is the compiler.

Visual Micro just does whatever the core tells it to do for whatever board you have chosen.

Thanks. That helps a lot. I use Nanos, Unos and Megas. I am assuming that all three use the Gnu C++ compiler. If that is the case, are there viable alternative C++ compilers that will give more meaningful error messages and would be usable in this environment?

Thanks for being patient with me on this.

I think you need to find an arduino code forum to ask these questions. This forum is just for tech support to get the arduino extension for vs working.
