Error Compiling latest Android 10 Kernel for Pixel 3XL (b1c1_defconfig) - error: LLVMgold.so: could not load plugin library

I'm using Ubuntu 20.04 and compiling the kernel for Pixel 3XL (crosshatch).

Adding LD=ld.gold to my script command doesn't fix the issue and gives the same error. Also, LLVMgold.so is inside the clang directory here: ~/KERNEL_DIRECTORY/linux-x86/clang-r353983c/lib64 (this is the path I'm using for LD_LIBRARY_PATH). I've copied LLVMgold.so to /usr/local/lib and other recommended locations with no luck. As always, thank you for reading and if you need more information, I'll be happy to share it with you.

Error:

nvm.. pretty sure I'm just missing "export" before LD_LIBRARY_PATH in my script command - John Herwig

I'm using Ubuntu 18.04 and compiling the kernel for Pixel 4 (flame). Thanks for your posting. It really helps me a lot.

Unfortunately I still got an error as below: GEN .version CHK include/generated/compile.h UPD include/generated/compile.h CC init/version.o AR init/built-in.o AR built-in.o LTO vmlinux.o ../scripts/link-vmlinux.sh: line 101: 18716 Killed ${LD} ${LDFLAGS} -r -o ${1} $(modversions) ${objects} /home/dongtaotao/msm/Makefile:1134: recipe for target 'vmlinux' failed make[1]: *** [vmlinux] Error 137 make[1]: Leaving directory '/home/dongtaotao/msm/out' Makefile:146: recipe for target 'sub-make' failed make: *** [sub-make] Error 2

Any suggestions?

This was too long for a comment so had to post as an answer:

My Pixel 4 Command where WORKING_DIRECTORY/out/host/linux-x86/bin/ contains some of my AOSP build tools (after running "repo init" and "repo sync" for the latest aosp branch for pixel 4, run "mmma system/libufdt/utils/src" instead of make). The main differences are the floral defconfig file and the specified LD=ld.lld linker

rm -rf out && export PATH=~/WORKING_DIRECTORY/out/host
