Crosscompile (for Yocto 2.6 Thud) RedisJSON

[TopperBG]

I want to target compile RedisJSON https://github.com/RedisJSON/RedisJSON

Building machine OS: Ubuntu 18.04.5 LTS

Target MACHINE is var-som-mx6 (NXP i.MX6Q)

Added meta-rust-bin layer in build/conf/bblayers.conf
On host OS build pass just fine with cargo build --release against git clone of RedisJSON

That's my Bitbake recipe:

Any ideas from where failed compilation ?

[posborne]

Looks like it failed trying to do bindgen stuff for redis-modules. Bindgen has additional requirements (libclang, etc.) that will need to be modeled in your recipe for the build to have a chance, but I don't have direct experience sorting out this particular issue so you'll need to do your own digging but we would love a comment back here if you find a solution or believe that something is missing from this layer that is required or would help with the process significantly.

You'll probably want to drop into a devshell and poke around, adding more verbose logging, etc.

[posborne]

Looks like this relates to #96

[posborne]

For now, the workaround mentioned in #75 is worth a shot.

[TopperBG]

Thanks a lot, will look for linket tickets. Will infor here for eventual resolution.
BTW yes, I have on host machine libclang-dev installed.

[TopperBG]

Not going right way. I've added in particular recipe for RedisJSON those rows:

export BINDGEN_EXTRA_CLANG_ARGS
BINDGEN_EXTRA_CLANG_ARGS = "--sysroot=${WORKDIR}/recipe-sysroot -I${WORKDIR}/recipe-sysroot/usr/include"

But error still exist even now is in use sysroot/types.h

That's more strange, the file exists:

#define __always_inline inline

but it's called relative from types.h

#define	__need_size_t
#include <stddef.h>

#ifdef __USE_MISC

BTW I'm useing Zeus branch of meta-rust-bin, could be that be a problem ?

[samliddicott]

This could also be related to rust-lang/cc-rs#82 especially this reply.

Otherwise for cross-compile, build-scripts compiled for host may fail to run in the case where the host has the same triple as the target, and then cargo assumes that the target tools can be used for the host, and target libc might be used.

For me, in a different project using host rust tools, this turned out to require:

+# enable nightly options
+RUSTENV+=__CARGO_TEST_CHANNEL_OVERRIDE_DO_NOT_USE_THIS="nightly"
+# CARGO_UNSTABLE_TARGET_APPLIES_TO_HOST enables CARGO_TARGET_APPLIES_TO_HOST in non-nightly builds (rust-lang/cc-rs#82 (comment))
+RUSTENV+=CARGO_UNSTABLE_TARGET_APPLIES_TO_HOST="true" CARGO_TARGET_APPLIES_TO_HOST="false"
+RUSTENV+=CARGO_TARGET_LINKER='$(CC)' TARGET_LINKER='$(CC)' TARGET_LD='$(CC)' TARGET_LDFLAGS= LDFLAGS=
+RUSTENV+=CARGO_TARGET_CC='$(CC)' TARGET_CC='$(CC)' TARGET_CFLAGS=

+# CARGO_UNSTABLE_HOST_CONFIG="true" enables CARGO_HOST_LINKER="gcc" and other host tools configurations
+RUSTENV+=CARGO_UNSTABLE_HOST_CONFIG="true"
+RUSTENV+=CARGO_HOST_LINKER=gcc HOST_LINKER=gcc HOST_LD=gcc HOST_LDFLAGS=
+RUSTENV+=CARGO_HOST_CC=gcc HOST_CC=gcc HOST_CFLAGS=
+
+RUSTENV+=RUSTFLAGS='$(RUSTFLAGS)'
+
+CARGO=env $(RUSTENV) cargo

I'm trying to use meta-rust-bin instead of host tools, but I'm not sure how those changes above would be transposed into this project.

[samliddicott]

This seems to be the equivalent fix in Kirkstone so that build/sciprt/build will have the correct linker so it can run on the host

https://git.openembedded.org/openembedded-core/commit/meta/recipes-devtools/rust?id=02133f92c56c90a5365985b515953e4136e112aa

[samliddicott]

I still find that cross-compiled code with a different triple produces build-script like this, using the loader in the uninative sysroot, and it executes fine:

$ file /build/arm/build_output/work/aarch64-soniccorex-linux/cbindgen/0.24.3-r0/target/release/build/log-6481e63a95fe6178/build-script-build
/build/arm/build_output/work/aarch64-soniccorex-linux/cbindgen/0.24.3-r0/target/release/build/log-6481e63a95fe6178/build-script-build: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /build/arm/build_output/sysroots-uninative/x86_64-linux/lib/ld-linux-x86-64.so.2, BuildID[sha1]=e2c81d808dc3867ea982e9d293ae9ee378c67568, for GNU/Linux 3.2.0, with debug_info, not stripped

But when cross compiled to the same triple as the host, it has the leading path to the loader stripped, to refer to plain /lib/... and won't run (file not found) because that loader isn't there on the host:

file /build/x86/build_output/work/corei7-64-soniccorex-linux/cbindgen/0.24.3-r0/target/release/build/log-6481e63a95fe6178/build-script-build
/build/x86/build_output/work/corei7-64-soniccorex-linux/cbindgen/0.24.3-r0/target/release/build/log-6481e63a95fe6178/build-script-build: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-x86-64.so.2, BuildID[sha1]=1f4ae69a4bd659a5844d8edf12c637772593ea87, for GNU/Linux 3.2.0, with debug_info, not stripped

So I'm not sure why, given all the precautions, the "interpreter" is different when building the build-script while cross compiling

[EDIT] the cause is that the linker-native-wrapper is not being invoked at all when the host and target triple match, so we need CARGO_TARGET_APPLIES_TO_HOST="false"

[samliddicott]

If you want to try this branch: https://github.com/samliddicott/meta-rust-bin/commits/master
then redis-json will build as far as do_package_qa:

ERROR: redis-json-git-r0 do_package_qa: QA Issue: -dev package redis-json-dev contains non-symlink .so '/usr/lib/librejson.so' [dev-elf]

That branch has @rich-g's fix #128
as well as my fix based on guidance from @jameshilliard here rust-lang/cc-rs#82 (comment)

I tested it cross-compiling on x86 for both arm and for a different x86

[samliddicott]

I see that @banditopazzo has a similar fix as a pull-request as of two weeks ago

[posborne]

Should be resolved as of #146
