Closed issue by kqo on void-packages repository

https://github.com/void-linux/void-packages/issues/22616

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:
  * Void 5.6.2 x86_64-musl GenuineIntel uptodate rrFFFF
* package:
  * arduino-cli
  * gcompat
  * musl-obstack

### Expected behavior

Binaries pulled in by `arduino-cli` which are linked against `glibc` should hopefully work on musl after #22237 (which fixed other missing symbols, thank you for that!).

### Actual behavior

The `arm-none-eabi-g++` binary pulled in by the `arduino:sam` core is still missing symbols from obstack, namely:

```
Error relocating [...]/arduino/packages/arduino/tools/arm-none-eabi-gcc/4.8.3-2014q1/bin/arm-none-eabi-g++: _obstack_newchunk: symbol not found
Error relocating [...]/arduino/packages/arduino/tools/arm-none-eabi-gcc/4.8.3-2014q1/bin/arm-none-eabi-g++: obstack_free: symbol not found
Error relocating [...]/arduino/packages/arduino/tools/arm-none-eabi-gcc/4.8.3-2014q1/bin/arm-none-eabi-g++: _obstack_begin: symbol not found
Error relocating [...]/arduino/packages/arduino/tools/arm-none-eabi-gcc/4.8.3-2014q1/bin/arm-none-eabi-g++: _obstack_memory_used: symbol not found
```

`gcompat` seems to support building with `musl-obstack`, so I [tried enabling support](https://github.com/void-linux/void-packages/compare/master...kqo:gcompat-arduino) in the template. I can see that `musl-obstack` gets linked in with `-lobstack`, but the binary still can't find the symbols, nor can I with `nm`.

I'm really out of my depth with this, so I'm not sure if this is a `gcompat` problem, something I'm doing wrong with `xbps`, or if I'm just misunderstanding how things are supposed to work.

### Steps to reproduce the behavior

This will bump into the binary needing obstack symbols:
```
$ arduino-cli core update-index
$ arduino-cli core install arduino:sam
$ arduino-cli sketch new test_sketch
$ arduino-cli compile test_sketch --fqbn arduino:sam:arduino_due_x_dbg
```

It's probably quicker to run:
```
$ LD_PRELOAD=/usr/lib/libgcompat.so.0 ldd ~/.local/share/arduino/packages/arduino/tools/arm-none-eabi-gcc/4.8.3-2014q1/bin/arm-none-eabi-g++
```

I'm still having it (seems to) on alpine-virt with gcompat:
```
asvm-x86-64:~/myapp/bin# ./arduino-cli compile --fqbn "esp32:esp32:nano32" ./sk1/
Error relocating /root/myapp/data/packages/esp32/tools/xtensa-esp32-elf-gcc/1.22.0-97-gc752ad5-5.2.0/bin/xtensa-esp32-elf-g++: obstack_free: symbol not found

Error during build: exit status 127
```

is there any oob solution?

i've installed (musl-obstack [package](https://pkgs.alpinelinux.org/package/edge/main/x86/musl-obstack)), but it did not work. I was too naive ;)

Comment:
First thing, we aren't Alpine, we are Void, so this repo isn't really correct.
But either way the issue is, that musl-obstack doesn't export a `obstack_free` function, only `_obstack_free`.

https://github.com/void-linux/musl-obstack Would be the upstream for `musl-obstack` for both Alpine and Void, you can open an isue there.

@Johnnynator Thanks a lot for your answers! I will definitely look in void-linux distro whether this issue is solved oob to jusut use it instead of alpine.
