Build Failure on macOS Monterey

[newbie-developer-1994]

Hello,

Cross Compiler build fails / Original makefile fails.

Following instructions on https://github.com/dthain/basekernel/wiki/Building-and-Running.

• Since running macOS, run ./build-cross-compiler.sh
• Failed with line rltty.c:83:7: error: implicit declaration of function 'ioctl' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
• Bypassed this by setting GDB="gdb-9.1", however makefile for gdb ended with make[1]: Nothing to be done for 'install-target'.

Added env var export PATH="$PWD/cross/bin:$PATH"

cdrtools and qemu are installed.

Running make fails, for both the committed configuration and the changed configuration (macOS):

Help. I am a professional in other areas. New to C stuff. But after reviewing your code, it is fascinating.

Hmm, it's been a while since I tried that configuration. Let me poke at it with my Mac and see what comes out. In the meantime, your error suggests to me that you have a partial build with one configuration, and then attempted to continue with another. Suggest that you do a make clean in the basekernel directory, and then make again to see if that helps.

Here is what I was able to observe this morning:

• Several versions of gdb do not build correctly on OSX 12.0.1. I haven't found a working version in the time available, let me know what you discover.
• However, gdb is not required to build and run the kernel, it's just helpful when troubleshooting. You can proceed without it, if the build script fails at the (final) gdb step.
• I think your current problem will be fixed with make clean and then make. Let me know if that works for you.

It worked. Off to experimenting!
