A number of the included example programs in the MPIDE 0023 release has errors when compiling.

Is that just my setup or has the examples not been fully tested ?

Not sure. It may be either (or both). Can you give more details on what's not compiling, and what types of errors?

In Examples in Arduino There are more, of course, but its a start. Doesn't seem to matter what board selection is chosen, same on Uno to Max32 etc Kim

What version of mpide are you running?

In file included from /usr/lib/gcc/avr/4.5.3/../../../avr/include/util/delay.h:44:0

This is a strange error to see. Were you compiling for a chipkit board when it produced the errors you quoted? An mpide build ought not be referencing /usr/lib/gcc at all for a PIC32 compile; it shouldn't even be in the search path. Can you quote the entire log from a "verbose" compile?

For Uno builds, you may be facing a compiler version incompatibility. On linux systems, Arduino relies on a separately-installed avr compiler, and not all linux package managers are set up to install a compatible (or even 'working') version of the AVR compiler.

Both Sweep and MotorKnob compile fine for me (for both Uno and Uno32 targets), using Mpide 0023-macosx-20111221 (which is the last "release" build...)

Edit: Also compiles fine for me using "MPIDE 20120811 RC4" The math.h problem does seem to be a famous libc bug that slipped through in assorted linux installs: http://lists.gnu.org/archive/html/avr-libc-dev/2011-10/msg00011.html (but it still shouldn't occur when building CPU32 targets.)

I have had some Ubuntu issues since I "upgraded" to 12.04
