Failed to Load CMake Project in CLion on M1 MacBook Air Using Bear and Generated CMakeLists #1

Open wuxiaoqiang12 opened 2 weeks ago

Hello,

First of all, I want to express my gratitude for your excellent tutorial. I was able to successfully compile the Linux kernel on my M1 chip MacBook Air. However, I encountered an issue when trying to load the project in CLion.

Here's what I did:

  1. I used Bear (https://github.com/rizsotto/Bear) to track the make process.
  2. Then, I generated a CMakeLists.txt file using the tool from this repository: https://github.com/habemus-papadum/kernel-grok.git.

But when I try to load the CMake project in CLion, it fails with numerous errors indicating that many files are missing.

Compiler exited with error code 1: /opt/homebrew/opt/llvm/bin/clang -xc -I/Users/xiaoqiang/Research/linux_kernel/linux/. -I/Users/xiaoqiang/Research/linux_kernel/linux/./include -g -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX14.5.sdk -Wp,-MMD,drivers/xen/xen-pciback/.conf_space.o.d -nostdinc -I.././arch/arm64/include -I.././arch/arm64/include/generated -I.././include -I.././arch/arm64/include/uapi -I.././arch/arm64/include/generated/uapi -I.././include/uapi -I.././include/generated/uapi -include .././include/linux/compiler-version.h -include .././include/linux/kconfig.h -include .././include/linux/compiler_types.h -D__KERNEL__ --target=aarch64-linux-gnu -fintegrated-as -mlittle-endian -DKASAN_SHADOW_SCALE_SHIFT= -fmacro-prefix-map=./= -std=gnu11 -fshort-wchar -funsigned-char -fno-common -fno-PIE -fno-strict-aliasing -Wall -Wundef -Wno-format-security -Wno-trigraphs -mgeneral-regs-only -DCONFIG_CC_HAS_K_CONSTRAINT=1 -Wno-psabi -fno-asynchronous-unwind-tables -fno-unwind-tables -mbranch-protection=pac-ret+bti -Wa,-march=armv8.5-a -DARM64_ASM_ARCH=\"armv8.5-a\" -DKASAN_SHADOW_SCALE_SHIFT= -fno-delete-null-pointer-checks -Wno-frame-address -Wno-format-truncation -Wno-format-overflow -Wno-address-of-packed-member -O2 -Wframe-larger-than=2048 -fstack-protector-strong -Wno-gnu -Wno-unused-but-set-variable -Wno-unused-const-variable -fno-omit-frame-pointer -fno-optimize-sibling-calls -ftrivial-auto-var-init=zero -fno-stack-clash-protection -falign-functions=4 -Wvla -Wno-pointer-sign -Wcast-function-type -fstrict-flex-arrays=3 -Wimplicit-fallthrough -fno-strict-overflow -fno-stack-check -Wno-initializer-overrides -Wno-sign-compare -Wno-pointer-to-enum-cast -Wno-tautological-constant-out-of-range-compare -Wno-unaligned-access -Wno-cast-function-type-strict -g -fno-var-tracking -mstack-protector-guard=sysreg -mstack-protector-guard-reg=sp_el0 -mstack-protector-guard-offset=1144 -DMODULE -DKBUILD_BASENAME=\"conf_space\" -DKBUILD_MODNAME=\"xen_pciback\" -D__KBUILD_MODNAME=kmod_xen_pciback -c -fpch-preprocess -v -dD -E

    error: error opening 'drivers/xen/xen-pciback/.conf_space.o.d': No such file or directory
    1 error generated.

Is there any specific configuration or additional steps I need to follow to resolve this issue? Any help would be greatly appreciated.

Thank you!

Hi, I'm glad that the build did work :)

I don't have any experience with CLion, so I don't know how to configure it.

But the error indicates that the compiler can't find some files, so I'd check if all the paths provided to clang really exist. For example, -dependency-file drivers/xen/xen-pciback/.conf_space.o.d looks suspicious — it can only work if you are in kernel root directory.

Maybe you can tell CLion to just use the existing makefile? I.e. call make LLVM=1 ARCH=arm64 -j $(sysctl -n hw.logicalcpu) HOSTCFLAGS="-I./" when you run Build/
