There are a couple problems. First, the name of the shell variable is
"enable_toolbox", not "toolbox". Second, your AM_CONDITIONAL() is checking
for a value of "yes", however you are setting the variable to true or false.
"yes" is not the same as true or false. Note also that AC_ARG_ENABLE(),
automatically sets enable_toolbox, so setting the variable again in the
'case' statement is redundant. Here is an improved version (with proper m4
quoting):
AC_ARG_ENABLE([toolbox],
[AC_HELP_STRING([--enable-toolbox], [build Atlas toolbox applications])],
[case $enableval in
yes|no) ;;
*) AC_MSG_ERROR([bad value $enableval for --enable-toolbox]) ;;
esac],
[enable_toolbox=yes])
AM_CONDITIONAL([TOOLBOX], [test $enable_toolbox = yes])
-- ES
