| 1702 | 1 INSTALLx.txt - cross-compiling Vim on Unix |

| 4 1. Introduction | |
| 5 2. Necessary arguments for "configure" | |
| 6 3. Necessary environment variables for "configure" | |
| 7 4. Example | |

| 10 1. INTRODUCTION | |
| 11 =============== | |
| 12 | |
| 13 This document discusses cross-compiling VIM on Unix-like systems. We assume | |
| 14 you are already familiar with cross-compiling and have a working cross-compile | |
| 15 environment with at least the following components: | |
| 16 | |
| 17 * a cross-compiler | |
| 18 * a libc to link against | |
| 19 * ncurses library to link against | |
| 20 | |
| 21 Discussing how to set up a cross-compile environment would go beyond the scope | |
| 22 of this document. See http://www.kegel.com/crosstool/ for more information and | |
| 23 a script that aids in setting up such an environment. | |
| 24 | |
| 25 | |
| 26 The problem is that "configure" needs to compile and run small test programs | |
| 27 to check for certain features. Running these test programs can't be done when | |
| 28 cross-compiling so we need to pass the results these checks would produce via | |
| 29 environment variables. See the list of variables and the examples at the end of | |
| 30 this document. | |
| 31 | |
| 32 | |
| 33 2. NECESSARY ARGUMENTS FOR "configure" | |
| 34 ====================================== | |
| 35 | |
| 36 You need to set the following "configure" command line switches: | |
| 37 | |
| 38 --build=... : | |
| 39 The build system (i.e. the platform name of the system you compile on | |
| 40 right now). | |
| 41 For example, "i586-linux". | |
| 42 | |
| 43 --host=... : | |
| 44 The system on which VIM will be run. Quite often this the name of your | |
| 45 cross-compiler without the "-gcc". | |
| 46 For example, "powerpc-603-linux-gnu". | |
| 47 | |
| 48 --target=... : | |
| 49 Only relevant for compiling compilers. Set this to the same value as | |
| 50 --host. | |
| 51 | |
| 52 --with-tlib=... : | |

53 Which terminal library to use. |
| 1621 | 54 For example, "ncurses". |
| 55 | |
| 56 | |
| 57 3. NECESSARY ENVIRONMENT VARIABLES FOR "configure" | |
| 58 ================================================== | |
| 59 | |
| 60 Additionally to the variables listed here you might want to set the CPPFLAGS | |
| 61 environment variable to enable optimization for your target system (e.g. | |
| 62 "CPPFLAGS=-march=arm5te"). | |
| 63 | |
| 64 The following variables need to be set: | |
| 65 | |
| 66 ac_cv_sizeof_int: | |
| 67 The size of an "int" C type in bytes. Should be "4" on all 32bit | |
| 68 machines. | |

71 If Python support is enabled, set this variable to the path for |
| 1621 | 72 Python's library implementation. This is a path like |
| 73 "/usr/lib/pythonX.Y/config" (the directory contains a file | |
| 74 "config.c"). | |

77 If Python support is enabled, set this variable to the execution |
| 1621 | 78 prefix of your Python interpreter (that is, where it thinks it is |
| 79 running). | |
| 80 This is the output of the following Python script: | |
| 81 import sys; print sys.exec_prefix | |

90 If Python support is enabled, set this variable to the version of the |
| 1621 | 91 Python interpreter that will be used. |
| 92 This is the output of the following Python script: | |
| 93 import sys; print sys.version[:3] | |
| 94 | |
| 95 vim_cv_bcopy_handles_overlap: | |
| 96 Whether the "memmove" C library call is able to copy overlapping | |
| 97 memory regions. Set to "yes" if it does or "no" if it does not. | |
| 98 You only need to set this if vim_cv_memmove_handles_overlap is set | |
| 99 to "no". | |
| 100 | |
| 101 vim_cv_getcwd_broken: | |
| 102 Whether the "getcwd" C library call is broken. Set to "yes" if you | |
| 103 know that "getcwd" is implemented as 'system("sh -c pwd")', set to | |
| 104 "no" otherwise. | |
| 105 | |
| 106 vim_cv_memcpy_handles_overlap: | |
| 107 Whether the "memcpy" C library call is able to copy overlapping | |
| 108 memory regions. Set to "yes" if it does or "no" if it does not. | |
| 109 You only need to set this if both vim_cv_memmove_handles_overlap | |
| 110 and vim_cv_bcopy_handles_overlap are set to "no". | |
| 111 | |
| 112 vim_cv_memmove_handles_overlap: | |
| 113 Whether the "memmove" C library call is able to copy overlapping | |
| 114 memory regions. Set to "yes" if it does or "no" if it does not. | |
| 115 | |
| 116 vim_cv_stat_ignores_slash: | |
| 117 Whether the "stat" C library call ignores trailing slashes in the path | |
| 118 name. Set to "yes" if it ignores them or "no" if it does not ignore | |
| 119 them. | |
| 120 | |
| 121 vim_cv_tgetent: | |
| 122 Whether the "tgetent" terminal library call returns a zero or non-zero | |
| 123 value when it encounters an unknown terminal. Set to either the string | |
| 124 "zero" or "non-zero", corresponding. | |
| 125 | |
| 126 vim_cv_terminfo: | |
| 127 Whether the environment has terminfo support. Set to "yes" if so, | |
| 128 otherwise set to "no". | |
| 129 | |
| 130 vim_cv_toupper_broken: | |
| 131 Whether the "toupper" C library function works correctly. Set to "yes" | |
| 132 if you know it's broken, otherwise set to "no". | |
| 133 | |
| 134 vim_cv_tty_group: | |
| 135 The default group of pseudo terminals. Either set to the numeric value | |

| 143 4. EXAMPLE: | |
| 144 =========== | |
| 145 | |
| 146 Assuming the target system string is "armeb-xscale-linux-gnu" (a Intel XScale | |
| 147 system) with glibc and ncurses, the call to configure would look like this: | |
| 148 | |
| 149 ac_cv_sizeof_int=4 \ | |
| 150 vim_cv_getcwd_broken=no \ | |
| 151 vim_cv_memmove_handles_overlap=yes \ | |
| 152 vim_cv_stat_ignores_slash=yes \ | |
| 153 vim_cv_tgetent=zero \ | |
| 154 vim_cv_terminfo=yes \ | |
| 155 vim_cv_toupper_broken=no \ | |
| 156 vim_cv_tty_group=world \ | |
| 157 ./configure \ | |
| 158 --build=i586-linux \ | |
| 159 --host=armeb-xscale-linux-gnu \ | |
| 160 --target=armeb-xscale-linux-gnu \ | |
| 161 --with-tlib=ncurses | |
