############################################################################## ## This file is a shell script fragment that supplies the information ## necessary to tailor a template configure script into the configure ## script appropriate for this directory. For more information, check ## any existing configure script. ## Be warned, there are two types of configure.in files. There are those ## used by Autoconf, which are macros which are expanded into a configure ## script by autoconf. The other sort, of which this is one, is executed ## by Cygnus configure. ## For more information on these two systems, check out the documentation ## for 'Autoconf' (autoconf.texi) and 'Configure' (configure.texi). ############################################################################## ### To add a new directory to the tree, first choose whether it is a target ### or a host dependent tool. Then put it into the appropriate list ### (library or tools, host or target), doing a dependency sort. For ### example, gdb requires that byacc (or bison) be built first, so it is in ### the ${host_tools} list after byacc and bison. # these libraries are used by various programs built for the host environment # host_libs="mmalloc libiberty opcodes bfd readline glob gash tcl tk tclX" # these tools are built for the host environment # host_tools="texinfo byacc flex bison binutils ld gas gcc gdb make patch prms send-pr gprof gdbtest tgas etc expect dejagnu sim m4 autoconf ispell grep diff rcs cvs fileutils shellutils textutils wdiff find emacs emacs19 uudecode hello tar gzip indent recode release sed utils" # these libraries are built for the target environment, and are built after # the host libraries and the host tools (which may be a cross compiler) # target_libs="libm xiberty newlib libio libg++" # these tools are built using the target libs, and are intended to run only # in the target environment # # note: any program that *uses* libraries that are in the "target_libs" # list belongs in this list. those programs are also very likely # candidates for the "native_only" list which follows # target_tools="examples groff" ################################################################################ ## These two lists are of directories that are to be removed from the ## ${configdirs} list for either cross-compilations or for native- ## compilations. For example, it doesn't make that much sense to ## cross-compile Emacs, nor is it terribly useful to compile xiberty in ## a native environment. # directories to be built in the native environment only # native_only="autoconf cvs emacs emacs19 fileutils find grep groff gzip hello indent ispell m4 rcs recode sed shellutils tar textutils gash tk uudecode wdiff gprof" # directories to be built in a cross environment only # cross_only="xiberty newlib" ## All tools belong in one of the four categories, and are assigned above ## We assign ${configdirs} this way to remove all embedded newlines. This ## is important because configure will choke if they ever get through. # configdirs=`echo ${host_libs} ${host_tools} ${target_libs} ${target_tools}` ################################################################################ srctrigger=move-if-change srcname="gnu development package" # This gets set non-empty for some net releases of packages. appdirs="" # per-host: # Work in distributions that contain no compiler tools, like Autoconf. if [ -d ${srcdir}/config ]; then case "${host}" in m68k-hp-hpux*) host_makefile_frag=config/mh-hp300 ;; m68k-apollo-sysv*) host_makefile_frag=config/mh-apollo68 ;; m68k-apollo-bsd*) host_makefile_frag=config/mh-a68bsd ;; m88k-dg-dgux*) host_makefile_frag=config/mh-dgux ;; m88k-harris-cxux*) host_makefile_frag=config/mh-cxux ;; m88k-motorola-sysv*) host_makefile_frag=config/mh-delta88;; mips*-dec-ultrix*) host_makefile_frag=config/mh-decstation ;; mips*-sgi-irix5*) host_makefile_frag=config/mh-irix5 ;; mips*-sgi-irix4*) host_makefile_frag=config/mh-irix4 ;; mips*-sgi-irix3*) host_makefile_frag=config/mh-sysv ;; mips*-*-sysv4*) host_makefile_frag=config/mh-sysv4 ;; mips*-*-sysv*) host_makefile_frag=config/mh-riscos ;; i[34]86-ncr-sysv43) host_makefile_frag=config/mh-ncrsvr43 ;; i[34]86-ncr-sysv4*) host_makefile_frag=config/mh-ncr3000 ;; i[34]86-*-sco*) host_makefile_frag=config/mh-sco ;; i[34]86-*-isc*) host_makefile_frag=config/mh-sysv ;; i[34]86-*-linux*) host_makefile_frag=config/mh-linux ;; i[34]86-*-solaris2*) host_makefile_frag=config/mh-sysv4 ;; i[34]86-*-aix*) host_makefile_frag=config/mh-aix386 ;; i[34]86-*-go32*) host_makefile_frag=config/mh-go32 ;; vax-*-ultrix2*) host_makefile_frag=config/mh-vaxult2 ;; *-ibm-aix*) host_makefile_frag=config/mh-aix ;; *-bull-bosx*) host_makefile_frag=config/mh-aix ;; *-*-solaris2*) host_makefile_frag=config/mh-solaris ;; m68k-sun-*) host_makefile_frag=config/mh-sun3 ;; *-sun-*) host_makefile_frag=config/mh-sun ;; *-hp-hpux*) host_makefile_frag=config/mh-hpux ;; *-*-hiux*) host_makefile_frag=config/mh-hpux ;; rs6000-*-lynxos*) host_makefile_frag=config/mh-lynxrs6k ;; *-*-lynxos*) host_makefile_frag=config/mh-lynxos ;; *-*-sysv4*) host_makefile_frag=config/mh-sysv4 ;; *-*-sysv*) host_makefile_frag=config/mh-sysv ;; esac fi # The Solaris /usr/ucb/cc compiler does not appear to work. case "${host}" in sparc-sun-solaris2*) if [ "`/usr/bin/which ${CC-cc}`" = "/usr/ucb/cc" ] ; then could_use= [ -d /opt/SUNWspro/bin ] && could_use="/opt/SUNWspro/bin" if [ -d /opt/cygnus/bin ] ; then if [ "$could_use" == "" ] ; then could_use="/opt/cygnus/bin" else could_use="$could_use or /opt/cygnus/bin" fi fi if [ "$could_use" = "" ] ; then echo "Warning: compilation may fail because you're using" echo "/usr/ucb/cc.
