Fix QEMU build script for arm config #58

Closed shawnpdoherty closed 1 year ago

shawnpdoherty commented 1 year ago

Build script for QEMU kernel fails on x86 build hosts because ARCH is not set for defconfig

*** Can't find default configuration "arch/x86/configs/versatile_defconfig"!

Set ARCH=arm to keep continuity and pass build.

For errata. The section labeled "Building a Kernel for QEMU" passes by the configuration altogether.

"Here is the sequence of commands to build Linux for the ARM Versatile PB that is emulated by QEMU, using the crosstool-NG v5TE compiler:" $ cd linux-stable $ make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabi- mrproper after clean, we need a .config file here, Instruction goes right to creating boot image, modules, and device tree blobs


$ make -j4 ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabi- zImage 
$ make -j4 ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabi- modules 
$ make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabi- dtbs

@shawnpdoherty thank you for your pull request. Your one-line change has been merged.

I will review your errata pertaining to "Building a Kernel for QEMU" and it to the README for this repo if that makes sense.

Thanks, yes that's perfect. Sorry to piggyback the errata on that Pull Request, wasn't sure how to get that looked at. Thanks very much
