New issue 2277 by [email protected]: GUB should bail unless a
special env var is set
http://code.google.com/p/lilypond/issues/detail?id=2277
GUB checks the host environment; if anything has changed, then it rebuilds
all packages, taking 2 or 3 times as long to build the binaries.
The CG has a helpful little script which sets up a new bash shell with
exactly the environment you want. Unfortunately, sometimes I forget to run
that script, so it starts rebuilding everything. I generally notice
halfway through, but then I'm concerned about leaving the cross-compile
with some packages rebuilt and some not rebuilt, so I just delete
everything and start from scratch.
It would be nice if the "make lilypond" target in GUB first checked if
there was a GUB_OK_TO_BUILD environment variable (or something like that),
and if there wasn't, it just exited with a message.
If we'd had this simple check, the 2.15.28 release would have been at least
six hours earlier than it actually will be, as well as saving literally
days of compiling time in the past.
