[bitbake-devel] [PATCH 1/2] build.py: add single-quotes around already-expanded directory name

[Peter Seebach]

If the computed name of a directory contains an undefined variable
reference, bitbake dutifully creates a directory with a name that has
${...} in it. However, the actual task script created then tries to cd
to that directory, and the cd command fails, because no such directory
exists -- because the shell has helpfully removed the ${...} which did
not match any actual variables.

Since we want the name to be used exactly-as-is, add single quotes around
the name so this doesn't cause strange failures running tasks, which
allows us to progress past such failures and get to a point where they
can be diagnosed.
