Hey Andrew!

 AA> It should only take a few seconds to build.

 # time make -j6
 real    0m0.197s
 user    0m0.728s
 sys     0m0.090s

Under 2 milliseconds.

 AA> If it fails to build, please post the output from make and we'll
 AA> see if we can pinpoint the cause.

Even though it successfully compiled here is the output anyhow;

 rmw: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, not stripped

The above was done on my custom pure 64-bit nondistribution rootfs (aka motorshed) using gcc-10.2.0/glibc-2.33 and friends.

Does this help any?

Life is good,
Maurice
