Only somewhat related to this patch, another problem that wasn't in your doci is that the current O= support doesn't support relative paths.
Yes I am aware of it and it is in the document as something that will be addressed later.
"Note: Relative paths don’t work - supporting relative paths breaks work-flows e.g: powerpc. Explore fix. Compile work-flows. Not planning to support at the moment."
Hi, Sorry to be dense but where is this documented (as quoted above)?
Thanks.
For example, using O=/tmp/build-arm64 works, but O=build-arm64 doesn't. Try this:
$ make ARCH=arm64 HOSTCC=gcc CROSS_COMPILE=aarch64-linux-gnu- O=build-arm64 defconfig $ make ARCH=arm64 HOSTCC=gcc CROSS_COMPILE=aarch64-linux-gnu- O=build-arm64 kselftest-all make[1]: Entering directory '/work/kernel/linux/build-arm64' make --no-builtin-rules INSTALL_HDR_PATH=$BUILD/usr \ ARCH=arm64 -C ../../.. headers_install make[4]: ../scripts/Makefile.build: No such file or directory make[4]: *** No rule to make target '../scripts/Makefile.build'. Stop. Makefile:500: recipe for target 'scripts_basic' failed make[3]: *** [scripts_basic] Error 2 Makefile:151: recipe for target 'khdr' failed make[2]: *** [khdr] Error 2 /work/kernel/linux/Makefile:1220: recipe for target 'kselftest-all' failed make[1]: *** [kselftest-all] Error 2 make[1]: Leaving directory '/work/kernel/linux/build-arm64' Makefile:179: recipe for target 'sub-make' failed make: *** [sub-make] Error 2
I am looking to address build and install issues first.
