This is invoked by the autoconf-generated 23# configure script. Putting it in a separate shell file lets us skip 24# running autoconf when modifying build-specific information. 25 26# This file switches on the shell variable ${build}. As much of this 27# as possible should be replaced with autoconf tests in the future. 28 29# This file sets the following shell variables for use by the 30# autoconf-generated configure script: 31# 32# build_xm_defines List of macros to define when compiling for the 33# build machine. 34# 35# build_xm_file List of files to include when compiling for the 36# build machine. 37# 38# build_install_headers_dir 39# Target to use when installing header files. 40# 41# build_exeext Set to the suffix, if the build machine requires 42# executables to have a file name suffix. 43 44# Default settings. 45build_xm_file= 46build_xm_defines= 47build_exeext= 48build_install_headers_dir=install-headers-tar 49build_file_translate= 50 51# System-specific settings. 52case $build in 53 hppa1.0-*-hpux1[01]* | \ 54 hppa*64*-*-hpux11* | \ 55 hppa1.1-*-hpux11* | \ 56 hppa2*-*-hpux11* ) 57 build_install_headers_dir=install-headers-cpio 58 ;; 59 i[34567]86-*-cygwin* | x86_64-*-cygwin* ) 60 build_xm_file=i386/xm-cygwin.h 61 build_exeext=.exe 62 ;; 63 i[34567]86-*-mingw32* | x86_64-*-mingw*) 64 build_xm_file=i386/xm-mingw32.h 65 build_exeext=.exe 66 t=`(CMD //c echo /c) 2>/dev/null` 67 case $t in ?:*) 68 build_file_translate="CMD //c" 69 ;; 70 esac 71 ;; 72 i[34567]86-pc-msdosdjgpp*) 73 build_xm_file=i386/xm-djgpp.h 74 build_exeext=.exe 75 ;; 76 *-*-sysv*) 77 # All other System V variants. 78 build_install_headers_dir=install-headers-cpio 79 ;; 80 *-*-*vms*) 81 # All OpenVMS targets. 82 build_xm_file="vms/xm-vms.h" 83 build_exeext=.exe 84 build_install_headers_dir=install-headers-cp 85 ;; 86esac 87 88
