I'm a bit confused here. So you're trying to build on x86_64-linux-gnu
, for armv6-linux-musleabihf
? or are you trying to build on aarch64-linux-gnu
?
The host which is building the binary is x86_64 The build target, so for which arch the final binary will be is armv6 And the target host is aarch64.
So in the end we would have a musl gcc compiler which runs on aarch64 and compiles to armv6 but all was build first on a x86_64.

Thanks for clarifying. The script doesn't currently self-host, but what you could probably do is
1) Build a toolchain targetting aarch64-linux-musl
as usual.
2) Using that toolchain, build whatever libraries are needed to build GCC (eg. zlib, libzstd, libatomic) for aarch64-linux-musl
.
3) After the first-pass toolchain has access to the required libraries, edit the ./configure
invocations for GCC & binutils and add --build=aarch64-linux-musl
. After that, build a toolchain targetting armv6-linux-musleabihf
.
In step 3, you'll need to run mussel.sh
on compatible hardware since once the new armv6-linux-musleabihf
compiler won't run on x86_64
, but on aarch64
. So, to answer your question, you'd either need access to an armv8 host or qemu-aarch64
to emulate it, at least as far as I know. Hope this helps.

Hello there,
Because discussions is not enabled for this repo, I place it here, as it's not an issue.
I wonder if someone every tried to do a canadian-cross compile with this? What my main goal is.
x86_64-linux-gnu
systemarmv6-linux-musleabihf
for exampleaarch64-linux-gnu
This way it would be possible to build cross-compilers for all the provided targets but then are able to run on a arm64/aarch64 host/architecture.
Else something like QEMU needs to be used to emulate the aarch64 architecture, which is probably not going to provide the best performance.
Someone an idea, or tried this before either using mussel or something else? And if so, does someone have any pointers?
Thanks in advance!
btw. I already tried to install the
aarch64-linux-gnu-g**
cross compilers, use that as GCC/G++ and added the correct--host
and--build
arguments to the configure commands.
