Hmm, you are right. The solaris /bin/sh is older revision of posix. > Does the configure script work if you replace /bin/sh with /bin/ksh > in your Solaris box yes, it does work if executed by /bin/bash or /bin/ksh > If yes, something like the following could be added to the beginning > of 'configure' > > option=option=value > if test ! x"${option$*=}" = x"value" 2>/dev/null; then > if test x"${PREVENT_LOOPING-}" = x; then > PREVENT_LOOPING=true; export PREVENT_LOOPING > test ! -x /bin/ksh || exec /bin/ksh "$0" "$@" > test ! -x /bin/bash || exec /bin/bash "$0" "$@" > fi > echo "Cannot find compatible shell for '$0'" >&2 > exit 1 > fi Unfortunately, no. The /bin/sh says "bad substitution" and does not run the script at all. I also tried eval 'echo ${A%%1}'; echo ok but that does not run the 'echo ok' and fails also. I can see three possible solutions 1) use bash or ksh in the shebang line 2) rewrite the script as I gave the overview 3) declare that solaris 10 /bin/sh is not compatible with configure script Frankly even 3) is viable option, one just have to remember to run 'bash configure'. If everything else would work, I would be happy :) Thank you -- Vlad
