Load pcre-6.0 into code/trunk.
1 dnl Process this file with autoconf to produce a configure script.
2
3 dnl This is required at the start; the name is the name of a file
4 dnl it should be seeing, to verify it is in the same directory.
5
6 AC_INIT(dftables.c)
7
8 dnl A safety precaution
9
10 AC_PREREQ(2.57)
11
12 dnl Arrange to build config.h from config.in. Note that pcre.h is
13 dnl built differently, as it is just a "substitution" file.
14 dnl Manual says this macro should come right after AC_INIT.
15 AC_CONFIG_HEADER(config.h:config.in)
16
17 dnl Provide the current PCRE version information. Do not use numbers
18 dnl with leading zeros for the minor version, as they end up in a C
19 dnl macro, and may be treated as octal constants. Stick to single
20 dnl digits for minor numbers less than 10. There are unlikely to be
21 dnl that many releases anyway.
22
23 PCRE_MAJOR=6
24 PCRE_MINOR=0
25 PCRE_DATE=07-Jun-2005
26 PCRE_VERSION=${PCRE_MAJOR}.${PCRE_MINOR}
27
28 dnl Default values for miscellaneous macros
29
30 POSIX_MALLOC_THRESHOLD=-DPOSIX_MALLOC_THRESHOLD=10
31
32 dnl Provide versioning information for libtool shared libraries that
33 dnl are built by default on Unix systems.
34
35 PCRE_LIB_VERSION=0:1:0
36 PCRE_POSIXLIB_VERSION=0:0:0
37 PCRE_CPPLIB_VERSION=0:0:0
38
39 dnl Checks for programs.
40
41 AC_PROG_CC
42
43 dnl For the C++ wrapper libpcrecpp.
44
45 AC_PROG_CXX

47 if test -n "$ac_cv_prog_ac_ct_CXX"; then
48 MAYBE_CPP_TARGETS='$(CPP_TARGETS)'
49 fi
50 echo "Maybe-cpp-targets: '$ac_cv_prog_CXX' '$MAYBE_CPP_TARGETS'" #!!
51 AC_SUBST(MAYBE_CPP_TARGETS)
52
53 dnl The icc compiler has the same options as gcc, so let the rest of the
54 dnl configure script think it has gcc when setting up dnl options etc.
55 dnl This is a nasty hack which no longer seems necessary with the update
56 dnl to the latest libtool files, so I have commented it out.
57 dnl
58 dnl if test "$CC" = "icc" ; then GCC=yes ; fi
59
60 AC_PROG_INSTALL
61 AC_LIBTOOL_WIN32_DLL
62 AC_PROG_LIBTOOL
63
64 dnl We need to find a compiler for compiling a program to run on the local host
65 dnl while building. It needs to be different from CC when cross-compiling.
66 dnl There is a macro called AC_PROG_CC_FOR_BUILD in the GNU archive for
67 dnl figuring this out automatically. Unfortunately, it does not work with the
68 dnl latest versions of autoconf. So for the moment, we just default to the
69 dnl same values as the "main" compiler. People who are corss-compiling will
70 dnl just have to adjust the Makefile by hand or set these values when they
71 dnl run "configure".
72
73 CC_FOR_BUILD=${CC_FOR_BUILD:-'$(CC)'}

80
81 dnl Checks for header files.
82
83 AC_HEADER_STDC
84 AC_CHECK_HEADERS(limits.h)
85
86 dnl These are C++ header files
87
88 AC_LANG_SAVE
89 AC_LANG_CPLUSPLUS
90 dnl I could be more clever here, given I'm doing AC_SUBST with this
91 dnl (eg set a var to be the name of the include file I want). But I'm not
92 dnl so it's easy to change back to 'regular' autoconf vars if we needed to.
93 AC_CHECK_HEADERS(bits/type_traits.h, [pcre_has_bits_type_traits="1"],
