Necessary arguments for "configure" + 3. Necessary environment variables for "configure" + 4. Example + + +1. INTRODUCTION +=============== + +This document discusses cross-compiling VIM on Unix-like systems. We assume +you are already familiar with cross-compiling and have a working cross-compile +environment with at least the following components: + + * a cross-compiler + * a libc to link against + * ncurses library to link against + +Discussing how to set up a cross-compile environment would go beyond the scope +of this document. See http://www.kegel.com/crosstool/ for more information and +a script that aids in setting up such an environment. + + +The problem is that "configure" needs to compile and run small test programs +to check for certain features. Running these test programs can't be done when +cross-compiling so we need to pass the results these checks would produce via +environment variables. See the list of variables and the examples at the end of +this document. + + +2. NECESSARY ARGUMENTS FOR "configure" +====================================== + +You need to set the following "configure" command line switches: + +--build=... : + The build system (i.e. the platform name of the system you compile on + right now). + For example, "i586-linux". + +--host=... : + The system on which VIM will be run. Quite often this the name of your + cross-compiler without the "-gcc". + For example, "powerpc-603-linux-gnu". + +--target=... : + Only relevant for compiling compilers. Set this to the same value as + --host. + +--with-tlib=... : + Which terminal library to. + For example, "ncurses". + + +3. NECESSARY ENVIRONMENT VARIABLES FOR "configure" +================================================== + +Additionally to the variables listed here you might want to set the CPPFLAGS +environment variable to enable optimization for your target system (e.g. +"CPPFLAGS=-march=arm5te"). + +The following variables need to be set: + +ac_cv_sizeof_int: + The size of an "int" C type in bytes. Should be "4" on all 32bit + machines. + +vi_cv_path_python_conf: + If Python support is enabled, set this variables to the path for + Python's library implementation. This is a path like + "/usr/lib/pythonX.Y/config" (the directory contains a file + "config.c"). + +vi_cv_var_python_epfx: + If Python support is enabled, set this variables to the execution + prefix of your Python interpreter (that is, where it thinks it is + running). + This is the output of the following Python script: + import sys; print sys.exec_prefix + +vi_cv_var_python_pfx: + If Python support is enabled, set this variables to the prefix of your + Python interpreter (that is, where was installed). + This is the output of the following Python script: + import sys; print sys.prefix + +vi_cv_var_python_version: + If Python support is enabled, set this variables to the version of the + Python interpreter that will be used. + This is the output of the following Python script: + import sys; print sys.version[:3] + +vim_cv_bcopy_handles_overlap: + Whether the "memmove" C library call is able to copy overlapping + memory regions. Set to "yes" if it does or "no" if it does not. + You only need to set this if vim_cv_memmove_handles_overlap is set + to "no". + +vim_cv_getcwd_broken: + Whether the "getcwd" C library call is broken. Set to "yes" if you + know that "getcwd" is implemented as 'system("sh -c pwd")', set to + "no" otherwise. + +vim_cv_memcpy_handles_overlap: + Whether the "memcpy" C library call is able to copy overlapping + memory regions. Set to "yes" if it does or "no" if it does not. + You only need to set this if both vim_cv_memmove_handles_overlap + and vim_cv_bcopy_handles_overlap are set to "no". + +vim_cv_memmove_handles_overlap: + Whether the "memmove" C library call is able to copy overlapping + memory regions. Set to "yes" if it does or "no" if it does not. + +vim_cv_stat_ignores_slash: + Whether the "stat" C library call ignores trailing slashes in the path + name. Set to "yes" if it ignores them or "no" if it does not ignore + them. + +vim_cv_tgetent: + Whether the "tgetent" terminal library call returns a zero or non-zero + value when it encounters an unknown terminal. Set to either the string + "zero" or "non-zero", corresponding. + +vim_cv_terminfo: + Whether the environment has terminfo support. Set to "yes" if so, + otherwise set to "no". + +vim_cv_toupper_broken: + Whether the "toupper" C library function works correctly. Set to "yes" + if you know it's broken, otherwise set to "no". + +vim_cv_tty_group: + The default group of pseudo terminals. Either set to the numeric value + of the your tty group or to "world" if they are world accessable. + +vim_cv_tty_mode: + The default mode of pseudo terminals if they are not world accessable. + Most propably the value "0620". + + +4. EXAMPLE: +=========== + +Assuming the target system string is "armeb-xscale-linux-gnu" (a Intel XScale +system) with glibc and ncurses, the call to configure would look like this: + +ac_cv_sizeof_int=4 \ +vim_cv_getcwd_broken=no \ +vim_cv_memmove_handles_overlap=yes \ +vim_cv_stat_ignores_slash=yes \ +vim_cv_tgetent=zero \ +vim_cv_terminfo=yes \ +vim_cv_toupper_broken=no \ +vim_cv_tty_group=world \ +./configure \ + --build=i586-linux \ + --host=armeb-xscale-linux-gnu \ + --target=armeb-xscale-linux-gnu \ + --with-tlib=ncurses + + + +Written 2007 by Marc Haisenko <marc@darkdust.net> for the VIM project. diff --git a/src/Make_os2.mak b/src/Make_os2.mak index e90f23e286..a0cc890cd6 100644 --- a/src/Make_os2.mak +++ b/src/Make_os2.mak @@ -4,7 +4,7 @@ # Created by: Paul Slootman # -### This Makefile has been succesfully tested on these systems. +### This Makefile has been successfully tested on these systems. ### Check the (*) column for remarks, listed below. ### Later code changes may cause small problems, otherwise Vim is supposed to ### compile and run without problems. diff --git a/src/auto/configure b/src/auto/configure index 386fc810e1..a0f3e92813 100755 --- a/src/auto/configure +++ b/src/auto/configure @@ -1,25 +1,82 @@ #! /bin/sh # Guess values for system-dependent variables and create Makefiles. -# Generated by GNU Autoconf 2.59. +# Generated by GNU Autoconf 2.62. # -# Copyright (C) 2003 Free Software Foundation, Inc. +# Copyright (C) 1992, 1993, 1994, 1995, 1996, 1998, 1999, 2000, 2001, +# 2002, 2003, 2004, 2005, 2006, 2007, 2008 Free Software Foundation, Inc. # This configure script is free software; the Free Software Foundation # gives unlimited permission to copy, distribute and modify it. ## --------------------- ## ## M4sh Initialization. ## ## --------------------- ## -# Be Bourne compatible +# Be more Bourne compatible +DUALCASE=1; export DUALCASE # for MKS sh if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then emulate sh NULLCMD=: - # Zsh 3.x and 4.x performs word splitting on ${1+"$@"}, which + # Pre-4.2 versions of Zsh do word splitting on ${1+"$@"}, which # is contrary to our usage.
