clang is not build in yocto for riscv arch. #235

Closed cghalibkhan closed 4 years ago

cghalibkhan commented 4 years ago

Hi guys,

Describe the bug clang is not build in yocto for RISCV arch. To Reproduce I was trying to build clang ( RISCV arch ) in yocto, for that i have followed this step's,

step1: git clone git://git.openembedded.org/openembedded-core step2: git clone https://github.com/openembedded/meta-openembedded.git step3: cd ${PWD}/openembedded-core && git clone git://git.openembedded.org/bitbake step4: cd ${PWD}/openembedded-core && git clone https://github.com/riscv/meta-riscv.git step5: mv ${PWD}/openembedded-core/meta-riscv/recipes-devtools/openocd ${PWD}/openembedded-core/meta-riscv/recipes-devtools/1openocd && cp -r ${PWD}/riscv-yocto/meta-openembedded/ step6: meta-oe/recipes-devtools/openocd ${PWD}/openembedded-core/meta-riscv/recipes-devtools/ step7: cd ${PWD}/openembedded-core && git clone https://github.com/kraj/meta-clang.git

step8: source oe-init-build-env

step9: export PATH=$(PWD)/openembedded-core/bitbake/bin:$(PATH)

step10: cd build

step11: bitbake-layers add-layer ../meta-riscv step12: bitbake-layers add-layer ../meta-clang

step13: Added TOOLCHAIN = "clang" >> ./conf/local.conf MACHINE = "freedom-u540" >> ./conf/local.conf

step14: bitbake meta-toolchain

step15: bitbake core-image-full-cmdline

Expected behavior output review : 

                      Here i haven't find clang of Target--riscv, But one thing i have noticed that clang for X86 has Build in following PATH but not for RISCV, I have attached log file's for your reference.

Additional context

        Can anyone please help me to build clang for RISCV arch,

Thank you, Ghalib khan.c

@cghalibkhan please use master or zeus branch for clang/risc-v since the backend support is new in clang9 and those branches are only ones supporting clang9 at the moment.
