Unable to compile mpy-cross on x86_64.

[RSC-Games]

A few days ago, I installed Debian on an old machine I had laying around. I set it up, then decided to install IDF 4.4.2 on it last night. I also cloned micropython (if you clone it with git clone --recursive https://github.com/micropython/micropython.git). This morning I ran a test build with a modified sdkconfig and it got to the qstr.i.last generation step. Then, while compiling mpy-cross, I got the following errors (with make V=1):

I've compiled micropython before with minimal issues on a Raspberry Pi. Unless something changed that I'm not aware of, then I probably cloned the repository wrong. Could somebody give me a pointer in the right direction please? It would be very helpful, as I cannot continue development of my system without compiling in C modules and frozen .mpy modules without compiling the source.

[robert-hh]

These are all standard C include files, not especially related to MicroPython. Looks like these are not installed. Did you run:

sudo apt-get build-essential

as mentioned e.g. in the MP readme for the unix port.

[RSC-Games]

It would appear that my libc version is too new. I guess it's because I installed dolphin from the sid branch but most of my packages are from bullseye. Should I reattempt this by fetching packages from the sid branch?

[robert-hh]

You should install the build-essential from the same source as the gcc compiler.

[RSC-Games]

I got build-essential from bullseye, and the compiler from bullseye. It would appear that the compiler does not want a libc6 version above 2.32, and I have 2.35. So I went ahead and installed the packages from the sid branch.

[RSC-Games]

It appears to be working but I had to reinstall my virtualenv for python 3.10

[RSC-Games]

mpy-cross built successfully. Thank you for your time!
