[Sbcl-devel] sb-thread on ARM7 ?

[Jeff C. <je...@jk...>]

I just pulled the source for 1.4.2 and tried to build it 
--with-sb-thread on an 4-core ARM 7 (RaspberryPi 2b). It failed almost 
immediately saying threads weren't available on this platform. I want to 
confirm if this is the case or if there's something else I need to do to 
build SBCL with threads on this device. Here are the details on the device:

pi@Raspberry-12:~/src/lisp/sbcl-1.4.2 $ uname -a
Linux WebPlay-1 4.9.60-v7+ #1048 SMP Fri Nov 3 16:05:21 GMT 2017 armv7l 
GNU/Linux
