Bashism nits:

• function download { is a bashism, use download () { instead.
• == is a bashism, use = instead.
• export CXXFLAGS=$CFLAGS needs to be quoted as export CXXFLAGS="$CFLAGS".

Consider running shellcheck to see some other bugs, but these ones break the script on /bin/sh -> dash systems even without, e.g., unusual characters in the directory name.

Also, ftp.gnu.org encourages the use of https.

Also, because POSIX doesn’t believe in first-order logic, set -e is not tripped by the failure of the first command in an && chain. Use separate commands instead. I got this error (which is puzzling in its own right, but should have at least triggered a script failure).

Maybe add -O2 to CFLAGS unless you meant to disable optimization? (Typical configure scripts default to -O2 only if CFLAGS is unset.)

-I${INSTALL_DIR}/include should be unnecessary if pkg-config is installed (and I don’t think this works if it isn’t).

@andersk Thanks for the notes. Curiously I did not see that ncurses error - I'm building in a Docker based on latest Fedora (because I am looking for a portable build for a RH-ish OS) - I guess the compilers differ.

What I am looking at now is a different set of ncurses configure options to try and get a typical binary output i.e. matching what you would see in a dist with ncurses installed.

/cc mobile-shell/mobile-shell.github.io#47

@andersk @javabrett the ncurses build failure is fixed by exporting CPPFLAGS="-P"
