I wasn't. Rust packages a particular llvm version already (and ties it into it's build scripts). I'm planning on just using that one. > I haven't tried it yet, but I've asked Servo developer, how they do > cross-builds and he said that it's really simple with Rust and Cargo, > which support cross-compilation by design. Well: >From what I've found, crossbuilds work fine if you're using one of a small set of blessed triples (ie: not arm-poky-linux-gnueabi, but arm-unknown-linux-gnueabihf), and you don't set any special CFLAGS/LDFLAGS variables (which oe does). And the infrastructure is not in place to allow packagers to easily add/use different triples and "linkers" (rustc calls gcc/cc to link it's programs, and as a result needs to know where it is). -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
