1104349Sphkdnl configuration script for expat 2104349Sphkdnl Process this file with autoconf to produce a configure script. 3104349Sphkdnl 4104349Sphkdnl Copyright 2000 Clark Cooper 5104349Sphkdnl 6104349Sphkdnl This file is part of EXPAT. 7104349Sphkdnl 8104349Sphkdnl EXPAT is free software; you can redistribute it and/or modify it 9104349Sphkdnl under the terms of the License (based on the MIT/X license) contained 10104349Sphkdnl in the file COPYING that comes with this distribution. 11104349Sphkdnl 12104349Sphk 13104349Sphkdnl Ensure that Expat is configured with autoconf 2.52 or newer 14104349SphkAC_PREREQ(2.52) 15104349Sphk 16104349Sphkdnl Get the version number of Expat, using m4's esyscmd() command to run 17104349Sphkdnl the command at m4-generation time. This allows us to create an m4 18104349Sphkdnl symbol holding the correct version number. AC_INIT() requires the 19104349Sphkdnl version number at m4-time, rather than when ./configure is run, so 20104349Sphkdnl all this must happen as part of m4, not as part of the shell code 21104349Sphkdnl contained in ./configure. 22104349Sphkdnl 23104349Sphkdnl NOTE: esyscmd() is a GNU M4 extension. Thus, we wrap it in an appropriate 24104349Sphkdnl test. I believe this test will work, but I don't have a place with non- 25104349Sphkdnl GNU M4 to test it right now. 26104349Sphkdefine([expat_version], ifdef([__gnu__], 27104349Sphk [esyscmd(conftools/get-version.sh lib/expat.h)], 28178848Scokane [2.0.x])) 29178848ScokaneAC_INIT(expat, expat_version, expat-bugs@libexpat.org) 30104349Sphkundefine([expat_version]) 31104349Sphk 32104349SphkAC_CONFIG_SRCDIR(Makefile.in) 33104349SphkAC_CONFIG_AUX_DIR(conftools) 34104349Sphk 35104349Sphk 36104349Sphkdnl 37104349Sphkdnl Increment LIBREVISION if source code has changed at all 38104349Sphkdnl 39104349Sphkdnl If the API has changed, increment LIBCURRENT and set LIBREVISION to 0 40104349Sphkdnl 41104349Sphkdnl If the API changes compatibly (i.e. simply adding a new function 42104349Sphkdnl without changing or removing earlier interfaces), then increment LIBAGE. 43104349Sphkdnl 44104349Sphkdnl If the API changes incompatibly set LIBAGE back to 0 45104349Sphkdnl 46104349Sphk 47178848ScokaneLIBCURRENT=6 48178848ScokaneLIBREVISION=2 49178848ScokaneLIBAGE=5 50104349Sphk 51104349SphkAC_CONFIG_HEADER(expat_config.h) 52104349Sphk 53104349Sphksinclude(conftools/libtool.m4) 54104349Sphksinclude(conftools/ac_c_bigendian_cross.m4) 55104349Sphk 56104349SphkAC_LIBTOOL_WIN32_DLL 57104349SphkAC_PROG_LIBTOOL 58104349Sphk 59104349SphkAC_SUBST(LIBCURRENT) 60104349SphkAC_SUBST(LIBREVISION) 61104349SphkAC_SUBST(LIBAGE) 62104349Sphk 63104349Sphkdnl Checks for programs. 64104349SphkAC_PROG_CC 65104349SphkAC_PROG_INSTALL 66104349Sphk 67104349Sphkif test "$GCC" = yes ;
