I receive the same error on Ubuntu 21.04 64-bit.

[poljar]

There are now binary releases of python-olm, which can be in the upstream gitlab repo: https://gitlab.matrix.org/matrix-org/olm/-/packages/28.

[poetaman]

@poljar Does that help macOS ARM64 (i.e aarch64)?

[poljar]

No, seems like only Linux builds are available.

[poljar]

So the issue here seems to be that the libolm fails to install a header if the Makefile build is used.

Upstream issue: https://gitlab.matrix.org/matrix-org/olm/-/issues/8.
