Facing bitbake errors with Yocto Jethro

[jaymindabhi]

Hi Team,

Facing error while integrating opeblas in Yocto Jethro (BB version - 1.28.0), aarch64-oe-linux target system.
Using "openblas_0.2.20.bb" recipe taken from - https://layers.openembedded.org/layerindex/recipe/68888/

Added "openblas" in local.conf.

Following is the error log:

Somehow this looks like a mix of 64bit armv8 and 32bit armv7, perhaps the autodetection failed.
But 0.2.20 is quite old anyway,could you try with current 0.3.6 instead ?
(I must admit I am not familiar with yocto)

[jaymindabhi]

I have tried with 0.3.6 version with following compilation configuration:

oe_runmake HOSTCC="${BUILD_CC}" CC="${TARGET_PREFIX}gcc ${TOOLCHAIN_OPTIONS}" CROSS_SUFFIX=${HOST_PREFIX} ONLY_CBLAS=1 HOSTCC="${BUILD_CC}" NOFORTRAN=1 USE_THREAD=0 NO_LAPACK=1 TARGET=ARMV8 ARCH=arm64

Still facing error, different one, described as below:

Is my compilation configuration command is correct or I am missing anything?
As I am cross compiling with Yocto, my architecture is arm64 (ARMV8).

Please suggest.

[martin-frbg]

I am not sure i understand the cross-compiling - do you intend to build an ArmV7 binary on ArmV8, or the other way round ?(Or is the actual compilation running on non-ARM hardware?)

[jaymindabhi]

I want to build binary for aarch64 architecture.

[martin-frbg]

The "ASMNAME redefined" is probably harmless (the partly recursive makefile structure does this when one supplies CFLAGS or similar).
The assembler error seems to suggest you are trying to use the wrong toolchain (32bit) to compile arm64 assembly according to
https://community.arm.com/developer/tools-software/oss-platforms/f/dev-platforms-forum/5274/issue-compiling-armv8-assembly

[brada4]

It bails out on aarch64 instructions. Looks like 32bit AS is in the way somehow.
Could you expand the build variables, like adding 'set' after failed build?

[brada4]

I found answer in your initial post, it is a 32bt compiler, ARMv7 is a 32bit arch.

-oemllib32-linux-gnueabi-

[jaymindabhi]

Let me try with ARMV7 architecture option.
Will update here with outcomes.

Thanks

[brada4]

Iit should be done by bb file already. The arch override does not work like you tried, you need full target toolchain

[jaymindabhi]

Below is my current openblas_0.3.6.bb file. Will set TARGET=ARMV7 BINARY=32 and update here. Meanwhile can you please let me know if I am missing any parameters in existing configuration? Do I need to add any other parameters during compilation?

[brada4]

Basic cross-compilation would be
make CC=target-arch-gcc FC=target-arch-gcc HOSTCC=cc
With particular build commands in your file it is designed to build only aarch64 version, so that aarch64 should be visible in build logs prominently.

[martin-frbg]

Did you get any further with this ?
