Previously, this relied on an (ugly, avr-specific) magic default for the
compiler.path variable, set by the IDE. This allowed the IDE to fall
back to a system-wide toolchain when no bundled toolchain was found (by
making compiler.path empty).
However,
- this only worked for avr, not sam,
- this worked only for gcc, a system-wide avrdude would break on the
avrdude.conf path in platform.txt, and
This would mean that automatic system-wide fallback didn't work in all
situations, so you'd still have to modify platform.txt (or create
platform.local.txt). Since doing that explictly is the most reliable
way, this commit removes the partial-working ability to do this
automatically.
Note that the code to automatically set compiler.path is still kept
around, in case third-party hardware still relies on this. At some
point, this code should be removed, but for now it just shows a warning
message.
"runtime.hardware.path" now contains the path to the hardware folder
of the currently selected board and "runtime.platform.path" the path
to the specific platform.
This should fix#1176 and #1761.
This resolves issue #1356 and add the ability for the Arduino IDE to
detect the amount of RAM allocated to a sketch and compare that to the
available RAM on each board. If RAM is more than 90% full, it will fail
on building since there is not enough free RAM for the heap and stack to
use.
