5 years ago Hi @dhalbert ,
are you sure there is no stray file in the folder where the Blink you are compiling lives?
The ./new:1:40: error: string looks suspicious.
I'll try on a clean 18.04 VM and will report back

5 years ago @facchinm Hmm, there is a file named new, but it is not in examples/01.Basics/Blink, it's in my home directory (!). It happens to contain some code with hid_report_descriptor. If I rename it to new1, the problem goes away. (There were files labeled new and old I was diff-ing.)
But this is now a different kind of bug. Why should a stray file named new be included in a compilation, and only for Nano 33 BLE? The panel icon I use to start arduino does start it up with my homedir as the current directory.

5 years ago Indeed it's very suspicious; paths outside compiler and core folders should never be included... Unless you have something overriding the default paths as environment variable. Could it be the case?

5 years ago I don't see any such env var; perhaps there is some typo in the Mbed build scripts (like a new instead of $new or something). The new is not affecting other board compilations. I'll poke around.

5 years ago .arduino15/packages/arduino/tools/arm-none-eabi-gcc/7-2017q4/arm-none-eabi/include/c++/7.2.1/functional has these includes:
Note the #include <new>. So somehow . is part of the include path.
#if __cplusplus >= 201103L
#include <new>
#include <tuple>
#include <type_traits>
#include <bits/functional_hash.h>
#include <bits/invoke.h>
#include <bits/std_function.h>
#if __cplusplus > 201402L
# include <unordered_map>
# include <vector>
# include <array>
# include <utility>
# include <bits/stl_algo.h>
#endifFor Arduino Nano 33 BLE< note, the -I.:
/home/halbert/.arduino15/packages/arduino/tools/arm-none-eabi-gcc/7-2017q4/bin/arm-none-eabi-g++ -c -I. ...In a vanilla Uno build, there is no -I. as a command-line arg on any of the compilation lines.

5 years ago Sorry for the slew of messages. In .arduino15/packages/arduino/hardware/mbed/1.1.2/platform.txt, there is:
...
compiler.c.flags=-c -I. {compiler.warning_flags} -Os -g -nostdlib "@{compiler.mbed.defines}" "@{compiler.mbed.cflags}" {compiler.mbed.arch.define} -MMD -mcpu={build.mcu}
...
compiler.cpp.flags=-c -I. {compiler.warning_flags} -g -Os -nostdlib "@{compiler.mbed.defines}" "@{compiler.mbed.cxxflags}" {compiler.mbed.arch.define} -MMD -mcpu={build.mcu}
...No other BSP platform.txt files that I have installed include -I.

5 years ago You are TOTALLY right. I don't know when that include path slipped into (it exist since the initial commit). I'm removing it right now; thank you so much for spotting this!
Using Arduino: 1.8.10 (tar file unpacked into personal
bindirectory) Arduino nRF528x (Mbed OS) 1.1.2 on Ubuntu 18.04 x64I get compilation errors when compiling the canonical Blink example. Blink compiles fine on Windows 10 with the same BSP and Arduino versions. After the first failure I removed
.arduino15and reinstalled the BSP to make sure everything was clean, and the errors still occur.
