1) When I do an initial checkout OR bzr update, I'm getting: # bzr update Doing on-the-fly conversion from RepositoryFormatKnitPack1() to RepositoryFormatKnitPack6(). This may take some time. Upgrade the repositories to the same format for better performance. Tree is up to date at revision 10807 of branch http://bzr.squid-cache.org/bzr/squid3/trunk Why is that? 2) How exactly do I proceed after the bzr checkout? automake autoconf ./configure ... ? I'm asking becuase automake is spitting into my face with: # automake configure.in:9: required directory ./cfgaux does not exist configure.in: no proper invocation of AM_INIT_AUTOMAKE was found. configure.in: You should verify that configure.in invokes AM_INIT_AUTOMAKE, configure.in: that aclocal.m4 is present in the top-level directory, configure.in: and that aclocal.m4 was recently regenerated (using aclocal). configure.in:37: required file cfgaux/config.guess' not found configure.in:37: automake --add-missing' can install config.guess' configure.in:37: required file cfgaux/config.sub' not found configure.in:37: automake --add-missing' can install config.sub' configure.in:48: required file cfgaux/install-sh' not found configure.in:48: automake --add-missing' can install install-sh' src/Common.am:29: USE_LOADABLE_MODULES does not appear in AM_CONDITIONAL compat/Makefile.am:5: src/Common.am' included from here compat/Makefile.am:12: Libtool library used but LIBTOOL' is undefined compat/Makefile.am:12: The usual way to define LIBTOOL' is to add AC_PROG_LIBTOOL' compat/Makefile.am:12: to configure.in' and run aclocal' and autoconf' again. compat/Makefile.am:12: If AC_PROG_LIBTOOL' is in configure.in', make sure compat/Makefile.am:12: its definition is in aclocal's search path. compat/Makefile.am: required file cfgaux/depcomp' not found compat/Makefile.am: automake --add-missing' can install depcomp' /usr/share/automake-1.11/am/depend2.am: am__fastdepCC does not appear in AM_CONDITIONAL ... -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt@xxxxxxxxxx | http://www.charite.de
