Re: [Discuss-gnuradio] Re: Intel Mac GNU Radio Install Update Soon

[Thomas Schmid]

I agree, we should not automate this, though a note in a "how to
install on a macbook" would be nice since a lot of people don't know
about that option.

A quick note of caution: I found out that sometimes compiling with -j2
gets errors, then restarting the process without -j2 compiles without
any errors. I assume that it is some dependency problems because one
of the processes did not finish yet.

Also, increasing to -j3 or -j4 might even increase the compile
performance since some of the make processes might be doing some
intensive IO work, thus the CPUs are free for compiling. I only
recently learnt that (thank you, Greg)...
