[swift-users] Build doesn't find ioctl.h

[Lane Schwartz]

Hi,

I'm attempting to build on Scientific Linux 7.1. I've made good progress,
but I just hit another error. The build can't find ioctl.h; it exists, just
not in the location the build system is looking for it:

$ ls /usr/include/linux/ioctl.h
> /usr/include/linux/ioctl.h

I'm assuming there should be a pretty trivial fix for this. Any suggestions
would be greatly appreciated.

Thanks,
