AC_PREREQ(2.50) dnl Get the version number of Subversion, using m4's esyscmd() command to run dnl the command at m4-generation time. This allows us to create an m4 dnl symbol holding the correct version number. AC_INIT() requires the dnl version number at m4-time, rather than when ./configure is run, so dnl all this must happen as part of m4, not as part of the shell code dnl contained in ./configure. dnl dnl NOTE: esyscmd() is a GNU M4 extension. Thus, we wrap it in an apprpriate dnl test. I believe this test will work, but I don't have a place with non- dnl GNU M4 to test it right now. define([subversion_version], ifdef([__gnu__], [esyscmd(build/getversion.py subversion/include/svn_version.h)], [0.x])) AC_INIT(subversion, subversion_version, [http://subversion.tigris.org/]) undefine([subversion_version]) dnl AC_CONFIG_SRCDIR is *required*; sanity-checks that our src dir exists.
