I believe most of our scripts depend on bash and not just a POSIX-compilant shell. If we haven't adapted them to say so explicitly, we probably should.

Is there a separate 'cpp' package containing the C preprocessor on Alpine Linux, separate from the C and C++ compilers? I'm not familiar with that distribution.

It seems like cpp (/usr/bin/cpp) is part of the gcc package:

I'm just surprised that when I install bash, I still get the busybox shell running it:

bash-4.3# echo $SHELL

/bin/ash

bash-4.3# ls -l /bin/ash

lrwxrwxrwx    1 root     root            12 Apr  1 18:56 /bin/ash -> /bin/busybox

This is a known issue on alpine:

Now just I would like to know what environment variable I should feed the shell so that charm++'s build finds the correct path for cpp.
