Colin Patrick McCabe commented on HADOOP-8489:
----------------------------------------------
Yeah, you're right.
It seems that CMake gets CMAKE_SYSTEM_PROCESSOR from the output of "uname -p",
and on some older versions of Linux this could return "amd64."
As for passing -m32 to the linker... there are some online sources that
recommend doing this for a 32-bit-build-on-64. The GNU ld documents themselves
seem silent on -m32 itself, although they do talk about some other options to
-m. So it's probably best to leave this for now, until we can determine that
it's not needed...
