[swift-users] Linux/armv5tel

[Jason Pepas]

Hi,

I'm attempting to build Swift for armv5tel (a Pogoplug) running Debian Jessie.

I'm building against Apple's 2016/2/8 snapshots, and LLVM fails on the
first file:

++ cmake_config_opt llvm
++ product=llvm
++ [[ Ninja == \X\c\o\d\e ]]
+ /usr/bin/cmake --build
/root/swift-build-scripts/build/buildbot_linux/llvm-linux-armv5 -- -j1
all

Has anyone else run into something similar?  Any ideas?

Thanks,
