Alpine Linux on x64 and AArch64

[Lilian BENOIT]

Hi Aleksei,

Thanks for your response.

devkit is a archive that i must download on musl.cc website.

This archive must uncompress on sysroot of qemu-debootstrap
cd ~/sysroot-arm64; unzip xxx-linux-musl-cross.tgz

my command is correct, isn't it ?


But i hesitate on two archives
  - https://musl.cc/aarch64-linux-musl-cross.tgz
  - https://musl.cc/x86_64-linux-musl-cross.tgz

I must use first ou second link if i want build on my computer (Linux 
debian x86 64) for aarch64 ?
In fact, first part is target or platform of build ?

Best Regards,
Lilian Benoit,
