This is a collection of autoconf macros which've been written by various people at CMU. To use it, use "aclocal -I cmulocal" (after the first time, automake should automatically use the -I cmulocal, if you've called CMU_INIT_AUTOMAKE in configure.in). CMU_INIT_AUTOMAKE If you use automake, you should call this after AM_INIT_AUTOMAKE. It adds "-I cmulocal" to the aclocal command line, so that when automake runs aclocal, aclocal'll continue to pick up these macros. CMU_ADD_LIBPATH Add -L(arg), and possibly -R(arg) (or whatever the runpath is) to LDFLAGS. CMU_ADD_LIBPATH_TO Likewise to above, except adds it to the specified variable (arg 2). CMU_GUESS_RUNPATH_SWITCH Attempts to guess what the runpath switch is (-R or whatever). CMU_COMERR Requires that com_err exist in the collection (at CMU, do this by running "cvs checkout com_err", and adding com_err to DIST_SUBDIRS in your Makefile.am). It sets the output variable COMPILE_ET to the compile_et program to use, and adds the appropriate paths to LDFLAGS and CPPFLAGS. It does *not* add -lcom_err to LIBS (this would cause later library checks to fail if com_err needs to be built), so Makefiles need to explicitly add -lcom_err (which, after all, should always exist as long as the com_err compile doesn't blow up). Makefiles should do this by using LIB_COMERR, which will substitute to the appropriate magic to use to grab the library. (This may involve a libtool archive; you should be using libtool to link your program if you distribute libraries with it that the program may link against). Note that com_err will only be compiled if the configure script can't find compile_et or libcom_err; if the system already has them, the configure script will use the system installation (although, due to some autoconf wonkiness, com_err will still be configured; it just won't show up in the @subdirs@ expansion). CMU_NANA Adds --with-nana, set by default; if set, attempts to link against libnana. If not set, or if libnana is unavailable, or if we're not using gcc, it defines WITHOUT_NANA. CMU_PROG_LIBTOOL Just like AM_PROG_LIBTOOL, except it performs a couple little hacks to make sure that things don't break on picky vendor compilers which whine about empty translation units. [DEPRECATED - DO NOT USE] CMU_PTHREADS This attempts to link against libpthread (failing if it can't be found), and attempts to do any system-specific setup required for thread support (for example, most things want _REENTRANT to be defined, but Solaris wants _POSIX_PTHREAD_SEMANTICS and __EXTENSIONS__, IRIX wants to see _SGI_REENTRANT_FUNCTIONS, etc). CMU_SASL This tries to find a SASL library, and calls AC_SUBST on LIB_SASL if it finds one, or tells the user to go ftp it if it doesn't exist. Provides --with-sasldir. CMU_KRB4 This attempts to find Kerberos 4 libraries and set up CFLAGS and LIBS appropriately. It also updates and substitutes RPATH for shared library stuff.
