Deprecated recipe.ar.pattern

[probonopd]

Arduino 1.6.6 hourly build 201510300355 suggests to consider upgrading this core:

./Arduino_1.6.6_201510300355
Picked up JAVA_TOOL_OPTIONS: 
Warning: platform.txt from core 'ESP8266 Modules' contains deprecated recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" {compiler.ar.flags} {compiler.ar.extra_flags} "{build.path}/{archive_file}" "{object_file}", automatically converted to recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" {compiler.ar.flags} {compiler.ar.extra_flags} "{archive_file_path}" "{object_file}". Consider upgrading this core.

Apparently changing this to {archive_file_path} removes the warning in 1.6.6 but breaks compatibility with 1.6.5.
I'm considering to leave the warning in place for now.

Ah! The Arduino IDE again. MdR. ;)

Is there any solution to fix that problem?

@fredericplante please double-check which board you have selected in Tools > Board menu.

core 'Arduino ARM (32-bits) Boards' and Warning: platform.txt from core 'Arduino ARM (32-bits) Boards' contains deprecated recipe.ar.pattern makes me think that you have some ARM board selected.

[fredericplante]

I don't know what to say.

When i reaload the right board, i get

+1, also seeing this error

[wireddude]

+1 seeing this too. downgraded to 1.6.5 for now and able to compile & flash just fine.

@igrr - this change seems to break building from Eclipse Arduino: The auto-generate makeFile will generate

Starting combiner
...xtensa-lx106-elf-gcc: error: arduino.ar: No such file or directory
makefile:89: recipe for target 'ESP_Configurable_Wifi_Connection.elf' failed

If I manually replace all instances of core.a with arduino.ar in the makefile and run make from the command line it will build. If I re-run from Eclipse, makefile gets rewritten and the build breaks.

Disclaimer: I don't know much about make and the auto-generation of it. I found 'arduino.ar' in some pref setting (environment/project/it.baeyens.arduino.core.toolChain.release.2078438648/A.ARCHIVE_FILE/value=arduino.ar) but that was also auto-reset when manually replacing it with 'core.a'.
