In m4/curses.m4, line 134, the 5th argument passed to AC_NCURSES was
surrounded by '"' instead of '[' and ']'. Because of that, the expansion
of AC_NCURSES in that case would produce the following line inside the
configure script (note the repeated double quotes):
screen_manager=""ncurses on $withval/include""
That would cause the following error when configure was executed with
the "--with-ncurses=dir" argument:
./configure: line 13468: on: command not found
Although in the case above the error doesn't actually influence the
build process ('screen_manager' isn't used anywhere in the script),
trying to execute 'on' might be harmful if it corresponded to an
existing command in the user's environment.

dnl Curses detection: Munged from Midnight Commander's configure.in
|
|
dnl
|
|
dnl What it does:
|
|
dnl =============
|
|
dnl
|
|
dnl - Determine which version of curses is installed on your system
|
|
dnl and set the -I/-L/-l compiler entries and add a few preprocessor
|
|
dnl symbols
|
|
dnl - Do an AC_SUBST on the CURSES_INCLUDEDIR and CURSES_LIBS so that
|
|
dnl @CURSES_INCLUDEDIR@ and @CURSES_LIBS@ will be available in
|
|
dnl Makefile.in's
|
|
dnl - Modify the following configure variables (these are the only
|
|
dnl curses.m4 variables you can access from within configure.in)
|
|
dnl CURSES_INCLUDEDIR - contains -I's and possibly -DRENAMED_CURSES if
|
|
dnl an ncurses.h that's been renamed to curses.h
|
|
dnl is found.
|
|
dnl CURSES_LIBS - sets -L and -l's appropriately
|
|
dnl CFLAGS - if --with-sco, add -D_SVID3
|
|
dnl has_curses - exports result of tests to rest of configure
|
|
dnl
|
|
dnl Usage:
|
|
dnl ======
|
|
dnl 1) Add lines indicated below to acconfig.h
|
|
dnl 2) call AC_CHECK_CURSES after AC_PROG_CC in your configure.in
|
|
dnl 3) Instead of #include <curses.h> you should use the following to
|
|
dnl properly locate ncurses or curses header file
|
|
dnl
|
|
dnl #if defined(USE_NCURSES) && !defined(RENAMED_NCURSES)
|
|
dnl #include <ncurses.h>
|
|
dnl #else
|
|
dnl #include <curses.h>
|
|
dnl #endif
|
|
dnl
|
|
dnl 4) Make sure to add @CURSES_INCLUDEDIR@ to your preprocessor flags
|
|
dnl 5) Make sure to add @CURSES_LIBS@ to your linker flags or LIBS
|
|
dnl
|
|
dnl Notes with automake:
|
|
dnl - call AM_CONDITIONAL(HAS_CURSES, test "$has_curses" = true) from
|
|
dnl configure.in
|
|
dnl - your Makefile.am can look something like this
|
|
dnl -----------------------------------------------
|
|
dnl INCLUDES= blah blah blah $(CURSES_INCLUDEDIR)
|
|
dnl if HAS_CURSES
|
|
dnl CURSES_TARGETS=name_of_curses_prog
|
|
dnl endif
|
|
dnl bin_PROGRAMS = other_programs $(CURSES_TARGETS)
|
|
dnl other_programs_SOURCES = blah blah blah
|
|
dnl name_of_curses_prog_SOURCES = blah blah blah
|
|
dnl other_programs_LDADD = blah
|
|
dnl name_of_curses_prog_LDADD = blah $(CURSES_LIBS)
|
|
dnl -----------------------------------------------
|
|
dnl
|
|
dnl
|
|
dnl The following lines should be added to acconfig.h:
|
|
