[stable-5.00] step 11, toolchain kernel headers fails to install #6

Closed gottaeat closed 5 years ago

gottaeat commented 5 years ago

i've followed the build steps with extreme caution but i'm given this error at step 11:

[07:04] mlfs /mnt/mss/apathymusl/sources/files/linux-5.2.11: make mrproper
[07:04] mlfs /mnt/mss/apathymusl/sources/files/linux-5.2.11: MLFS_ARCH=${MLFS_CPU} make INSTALL_HDR_PATH=dest headers_install

compilation terminated.
make[1]: *** [scripts/Makefile.host:90: scripts/basic/fixdep] Error 1

can provide any extra details if desired.

following these steps from stable-4.0.0 fixes the problem:

make mrproper

PATH=/bin:/usr/bin:/cross-tools/bin:/tools/bin \
MLFS_ARCH=x86 make INSTALL_HDR_PATH=dest headers_install

find dest/include \( -name .install -o -name ..install.cmd \) -delete

cp -rv dest/include/* /tools/include

this time another header issue but with binutils pass 2 at step 14:

I just uploaded comit 8a6713d6a4ae2db7fda798a608f2993985f08b05 that fixed a number of typos, including step 11. Correct command: ARCH=${MLFS_CPU} make INSTALL_HDR_PATH=dest headers_install with ${MLFS_CPU} set to x86 (x86_64 & i686) or arm for arm CPU's.

With the commit i just submitted, creating a GCC specs file for /cross-tools seems to fix that issue where in step 11 the $PATH has to be reversed.

stable-4.00 supposedly builds fine after the /tools tool-chain is properly built... I completed a build on a i686 machine (HP nc6400) that already uses musl. I did not realize stable-4.00 fails to build on non-musl hosts.

Step 10 [TC: GCC Pass1] still requires a reversal of $PATH to complete build. I am still unsure why.

Also I noticed if binutils or GCC fails to build/install while building /tools, /tools has to be rebuilt after changes are made to build instructions. Don't forget to set the cross-compiling environment if logging out and loggin back in as mlfs user.

So far I got CT(/cross-tools) and TC(/tools) to build fine on an x86_64-glibc host (Toshiba m400) and a armv7l-glibc host (Odroid Xu4) using the latest commit.

looks like the last changes you've made fixed that problem but also introduced a new one:

 [07:11] mlfs /mnt/mlfs/sources/files/linux-5.2.11: ARCH=${MLFS_CPU} make INSTALL_HDR_PATH=dest head
 ers_install
 Makefile:649: arch/x86-64/Makefile: No such file or directory
 make: *** No rule to make target 'arch/x86-64/Makefile'.  Stop.
 [07:11] mlfs /mnt/mlfs/sources/files/linux-5.2.11: echo $MLFS_CPU
 x86-64

there's no x86_64 under arch/, resulting in this error. passing just x86 or not setting the ARCH variable fixes it and headers get installed to dist fine.

can confirm that with my 5th attempt at this in the last 2 months, i've managed to build the toolchain successfully. thanks for sharing your experiments. looking forward to the actual system build.
