When trying to use XCode to compile an open source project on Mac OS X Mountain Lion, you might have realized that build tools like GNU Autoconf, Automake or Libtool are no longer available. I think these tools have been removed with XCode 4.3.
One way to make them available again, is to download the source and build them with this script:
#!/bin/bash # type of compression #COMPRESSION=gz #COMPRESSIONFLAGS=-zxf COMPRESSION=xz COMPRESSIONFLAGS=-Jxf # # path to curl CURL=/usr/bin/curl # set to empty if working as root or if you are able to write to /usr/local/ SUDO="" #SUDO=/usr/bin/sudo # # version of autoconf VAUTOCONF=2.69 # # version of automake VAUTOMAKE=1.15 # # version of libtool VLIBTOOL=2.4.6 CURRENTDIR=`pwd` cd $CURRENTDIR $CURL -OL http://ftpmirror.gnu.org/autoconf/autoconf-$VAUTOCONF.tar.$COMPRESSION tar $COMPRESSIONFLAGS autoconf-$VAUTOCONF.tar.$COMPRESSION cd autoconf-$VAUTOCONF ./configure && make && $SUDO make install cd $CURRENTDIR $CURL -OL http://ftpmirror.gnu.org/automake/automake-$VAUTOMAKE.tar.$COMPRESSION tar $COMPRESSIONFLAGS automake-$VAUTOMAKE.tar.$COMPRESSION cd automake-$VAUTOMAKE ./configure && make && $SUDO make install cd $CURRENTDIR $CURL -OL http://ftpmirror.gnu.org/libtool/libtool-$VLIBTOOL.tar.$COMPRESSION tar $COMPRESSIONFLAGS libtool-$VLIBTOOL.tar.$COMPRESSION cd libtool-$VLIBTOOL ./configure && make && $SUDO make install
After it ran without errors, the tools are available in /usr/local.
Further you might also need pkg-config. This can be build with this script:
#!/bin/bash # type of compression COMPRESSION=gz COMPRESSIONFLAGS=-zxf # # path to curl CURL=/usr/bin/curl # set to empty if working as root or if you are able to write to /usr/local/ SUDO="" #SUDO=/usr/bin/sudo # # version of pkg-config VPKGCONFIG=0.29.1 CURRENTDIR=`pwd` cd $CURRENTDIR $CURL -OL https://pkg-config.freedesktop.org/releases/pkg-config-$VPKGCONFIG.tar.$COMPRESSION tar $COMPRESSIONFLAGS pkg-config-$VPKGCONFIG.tar.$COMPRESSION cd pkg-config-$VPKGCONFIG ./configure --with-internal-glib && make && $SUDO make install
For Mac OS X it is important that you use at least version 0.29.1 of pkg-config. Otherwise you would get linking errors. Afterwards pkg-config is also available in /usr/local.
