Cannot build because of missing 32-bit GNU stubs and missing libgcc

[viktorpopp]

So i am building my own bootloader in C right now and have come across two quite annoying issues. Whenever i build with the default CC set by my shell i get the following error:

/usr/include/gnu/stubs.h:7:11: fatal error: gnu/stubs-32.h: No such file or directory
    7 | # include <gnu/stubs-32.h>
      |           ^~~~~~~~~~~~~~~~

But that can be fixed by forcing clang instead. I think it would be better if it was possible just to use GCC normally if possible, because it does work just fine in an Ubuntu distrobox.

The second issue that i cannot link libgcc for 32-bit architectures because i use 64-bit integers. I added this in my makefile which i link against:

LIBGCC := $(shell $(CC) $(CFLAGS) -m32 -print-libgcc-file-name)

But again. The issue is that clang is in my distrobox so that path doesn't work...

Any ideas on how to fix this?

have you tried using a toolbox for this exclusively? ideally, you would:

• create a toolbox: toolbox create -c lime-boot-box
• install tools, libs, compiles etc. on the toolbox: toolbox enter lime-boot-box
• iterate on development and address any env/setup issues as they arise

this is exactly the kind of scenario that toolbox/distrobox excels at. in case you need a different distro (e.g., ubuntu), you can specify that as well: toolbox create -d ubuntu -r 24.04 -c lime-boot-box.

Yes i did. And thats when it worked. Now i just include a config file where i define LIBGCC and CLANG: https://github.com/zinix-org/lime-boot/blob/main/Makefile#L11
