1 NUT-specific autoconf macros
2 ----------------------------
4 The following NUT-specific autoconf macros are defined in the m4/
11 Check for the corresponding type in the system header files, and
12 #define a replacement if necessary.
17 - NUT_CHECK_LIBNETSNMP
18 - NUT_CHECK_LIBPOWERMAN
19 - NUT_CHECK_LIBOPENSSL
24 Determine the compiler flags for the corresponding library. On
25 success, set nut_have_libxxx="yes" and set LIBXXX_CFLAGS and
26 LIBXXX_LDFLAGS. On failure, set nut_have_libxxx="no". This macro
27 can be run multiple times, but will do the checking only once.
28 Here "xxx" should of course be replaced by the respective library name.
30 The checks for each library grow organically to compensate for
31 various bugs in the libraries, pkg-config, etc. This is why we have
32 a separate macro for each library.
36 Check for various features required to compile the IPv6 support.
37 dnl Check for various features required for IPv6 support. Define a
38 preprocessor symbol for each individual feature (HAVE_GETADDRINFO,
39 HAVE_FREEADDRINFO, HAVE_STRUCT_ADDRINFO, HAVE_SOCKADDR_STORAGE,
40 SOCKADDR_IN6, IN6_ADDR, HAVE_IN6_IS_ADDR_V4MAPPED,
41 HAVE_AI_ADDRCONFIG). Also set the shell variable nut_have_ipv6=yes
42 if all the required features are present. Set nut_have_ipv6=no
47 Check for the exact system name and type.
48 This was only used in the past to determine the packaging rule to be used
49 through the OS_NAME variable, but may be useful for other purposes in the
52 - NUT_REPORT_FEATURE(FEATURE, VALUE, VARIABLE, DESCRIPTION)
54 Schedule a line for the end-of-configuration feature summary. The
55 FEATURE is a descriptive string such that the sentence "Checking
56 whether to FEATURE" makes sense, and VALUE describes the decision
57 taken (typically yes or no). The feature is also reported to the
60 Also use VARIABLE and DESCRIPTION for defining AM_CONDITIONAL and
61 AC_DEFINE (only if VALUE = "yes"). VARIABLE is of the form 'WITH_<NAME>'.
63 - NUT_REPORT(FEATURE, VALUE)
65 Schedule a line for the end-of-configuration feature summary, without
66 printing anything to the terminal immediately.
68 - NUT_PRINT_FEATURE_REPORT
70 Print out a list of the features that have been reported by
71 previous NUT_REPORT_FEATURE macro calls.
73 - NUT_ARG_WITH(FEATURE, DESCRIPTION, DEFAULT)
75 Declare a simple --with-FEATURE option with the given DESCRIPTION
76 and DEFAULT. Sets the variable nut_with_FEATURE.
