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 13247296Sdelphijdnl Ensure that Expat is configured with autoconf 2.58 or newer 14247296SdelphijAC_PREREQ(2.58) 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)], 28247296Sdelphij [2.1.x])) 29178848ScokaneAC_INIT(expat, expat_version, expat-bugs@libexpat.org) 30104349Sphkundefine([expat_version]) 31104349Sphk 32104349SphkAC_CONFIG_SRCDIR(Makefile.in) 33104349SphkAC_CONFIG_AUX_DIR(conftools) 34247296SdelphijAC_CONFIG_MACRO_DIR([m4]) 35104349Sphk 36104349Sphk 37104349Sphkdnl 38104349Sphkdnl Increment LIBREVISION if source code has changed at all 39104349Sphkdnl 40104349Sphkdnl If the API has changed, increment LIBCURRENT and set LIBREVISION to 0 41104349Sphkdnl 42104349Sphkdnl If the API changes compatibly (i.e. simply adding a new function 43104349Sphkdnl without changing or removing earlier interfaces), then increment LIBAGE. 44104349Sphkdnl 45104349Sphkdnl If the API changes incompatibly set LIBAGE back to 0 46104349Sphkdnl 47104349Sphk 48247296SdelphijLIBCURRENT=7 49247296SdelphijLIBREVISION=0 50247296SdelphijLIBAGE=6 51104349Sphk 52104349SphkAC_CONFIG_HEADER(expat_config.h) 53104349Sphk 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 65247296SdelphijAC_PROG_CXX 66104349SphkAC_PROG_INSTALL 67104349Sphk 68104349Sphkif test "$GCC" = yes ;
