[Solved] "#include <M5Core2.h>" doesn't compile

[rh1972]

My code has the following with empty setup and loop:

#include <M5Core2.h>

When I verify, it terminates with this:

c:\users\xxxxx xxxxx\appdata\local\arduino15\packages\m5stack\tools\xtensa-esp32-elf-gcc\gcc8_4_0-esp-2021r2-patch5\xtensa-esp32-elf\include\c++\8.4.0\bits\allocator.h:46:10: fatal error: bits/c++allocator.h: No such file or directory

The file does exist in that location. File doesn't exist in this location, but exists in other directories.

I'm compiling this on a Core 2, using this guide:

https://docs.m5stack.com/en/quick_start/core2/arduino

So, what am I doing wrong?

Hi!
I verify this simple code no problem.
#include <M5Core2.h>
void setup() {
}
void loop() {
}
Is this what you were talking about?

Hi, thanks for the reply.

While writing my reply, I realised I misread the error. Arduino IDE cannot find "bits/c++allocator.h" which indeed doesn't exist in this directory. It exists in multiple different directories, though.

I coped "c++allocator.h" into the path stated in my original post, and it got over this error. But, it's now missing another file.

I could copy all these missing files (assuming there's more), but something seems to be wrong here.

@rh1972 said in "#include <M5Core2.h>" doesn't compile:

c++allocator.h

My recent install of Arduino V2.0.3 doesn't have c++allocator.h installed and I could not find it anywhere in my computer.

So, yes! I agree there must be something else wrong.
Are you using Arduino V2.0.3?

[rh1972]

Yeah, I'm using v2.0.3
I installed the "M5Stack" boards, and then the "M5Core2" libraries, including dependencies. I've tried different versions of the boards.

I'm I missing something obvious?

[rh1972]

Well, it's working.

The path to my Windows profile has a space in it. I created a local account without a space, and my empty program compiled with no issues. Don't know if that's the reason. Very strange.

Makes me want to reinstall Ubuntu, or something.

Thanks for the replies, Terry.
