That's error coming from boost.context library build for assembly code. Don't think there's arm64 support there for gcc -- seems like it's looking for clang. Obviously if you're not using boost.context you can ignore. Not seeing an issue for this, but maybe worthy of filing a report: https://github.com/boostorg/context/issues libs/context/build/Jamfile.v2 # ARM64 # ARM64/AAPCS/ELF alias asm_sources : asm/make_arm64_aapcs_elf_gas.S asm/jump_arm64_aapcs_elf_gas.S asm/ontop_arm64_aapcs_elf_gas.S : <abi>aapcs <address-model>64 <architecture>arm <binary-format>elf <toolset>clang ; alias asm_sources : asm/make_arm64_aapcs_elf_gas.S asm/jump_arm64_aapcs_elf_gas.S asm/ontop_arm64_aapcs_elf_gas.S : <abi>aapcs <address-model>64 <architecture>arm <binary-format>elf <toolset>gcc ; # ARM64/AAPCS/MACH-O alias asm_sources : asm/make_arm64_aapcs_macho_gas.S asm/jump_arm64_aapcs_macho_gas.S asm/ontop_arm64_aapcs_macho_gas.S : <abi>aapcs <address-model>64 <architecture>arm <binary-format>mach-o <toolset>clang ; On Mon, Apr 20, 2020 at 6:44 AM Rahul Sreeram via Boost-users < boost-users@lists.boost.org> wrote:
Hi,
I am trying to build boost 1.72 with arm 64 bit compiler. I am seeing the error: No best alternative for libs/context/build/asm_sources Although, after getting this error, compilation looks to succeed, but I am not sure if it did properly or not.
I have this line in the project-config.jam: using gcc : arm : aarch64-fsl-linux-g++ --sysroot=/sysroots/aarch64-fsl-linux ;
After running b2, I get the following output: ./b2 toolset=gcc-arm Performing configuration checks
- default address-model : 64-bit - default architecture : arm
