Crosscompiling for Aarch64

[phodina]

Hi,

I've attempted to cross-compile the liblockdev pkg for Aarch64. However, there seems to be some issue with the linker, see the attached log. I'm running version 2.25 on Guix (x86_64 builds ok).

Any ideas what could be the cause?

Nothing specific here, looks like g-ir-scanner is calling libtool to link the generated sources but I don't see any real error message in the output. You may try compiling with make V=1 -j1 but that's a long shot.

Alternatively, just switch to /tmp/guix-build-libblockdev-2.25.drv-0/libblockdev-2.25/src/lib and call the libtool command manually. Perhaps it'll give you more precise error message.

Thanks @tbzatek ! I'll try the flag and without parallel build
