I added musl overlay to my RPi3B

RPi3B:~ # emerge --info '=sys-devel/gcc-8.2.0-r3::gentoo' | wgetpaste

Portage 2.3.49 (python 3.6.6-final-0, default/linux/arm64/17.0, gcc-8.2.0, glibc-2.27-r6, 4.19.0-rc6-v8+ aarch64)

necktwi ... that is not a musl profile ... you're using glibc. Yet ...

emerge --info:
CBUILD="aarch64-RPi3B-linux-musl"
CHOST="aarch64-RPi3B-linux-musl"

You can not arbitrarily switch CHOST ... and hope it will work.

but `crossdev -t aarch64-RPi3B-linux-musl` has created `/usr/aarch64-RPi3B-linux-musl/etc/make.conf` with
Code:

CHOST=aarch64-RPi3B-linux-musl
CBUILD=x86_64-pc-linux-gnu


is it the other way around in crossdev env?

I just copied CHOST from there when I porting to musl.

Thank you!

necktwi ...

you didn't mention crossdev ... however, this is the same arch, so you don't need a crossdev, all you need do is unpack a musl stage3, chroot, and build your system (though I'm not sure why you didn't, or don't, start from a musl stage3 to begin with, or what you're trying to achieve).

Is there an aarch64-musl stage 3? I could only find armv7 stage 3. But I need armv8a stage 3. If there is one please share a link.

Thanq!

necktwi ... it seems that the musl port to aarch64 is "less than 30% complete". So, no, but that also means there is no chance for crossdev also.
