[LLVMdev] Can libc++ build for arm cross compiler? (original) (raw)

cschen,

When testing my baremetal stuff, I usually do something like this:

$ qemu-system-arm -semihosting -M integratorcp -cpu arm1026 -kernel ./aa

For your target, the process will be a little different because you'll need to set up the whole OS within QEMU, and then scp ./aa over to the guest OS and run it there. Unfortunately, I don't have a script that I can share that does that for non-baremetal toolchains.

Cheers,

Jon
