NUT-specific autoconf macros
|
|
----------------------------
|
|
|
|
The following NUT-specific autoconf macros are defined in the m4/
|
|
directory.
|
|
|
|
- NUT_TYPE_SOCKLEN_T
|
|
- NUT_TYPE_UINT8_T
|
|
- NUT_TYPE_UINT16_T
|
|
|
|
Check for the corresponding type in the system header files, and
|
|
#define a replacement if necessary.
|
|
|
|
- NUT_CHECK_LIBGD
|
|
- NUT_CHECK_LIBNEON
|
|
- NUT_CHECK_LIBNETSNMP
|
|
- NUT_CHECK_LIBPOWERMAN
|
|
- NUT_CHECK_LIBOPENSSL
|
|
- NUT_CHECK_LIBNSS
|
|
- NUT_CHECK_LIBUSB
|
|
- NUT_CHECK_LIBWRAP
|
|
|
|
Determine the compiler flags for the corresponding library. On
|
|
success, set nut_have_libxxx="yes" and set LIBXXX_CFLAGS and
|
|
LIBXXX_LDFLAGS. On failure, set nut_have_libxxx="no". This macro
|
|
can be run multiple times, but will do the checking only once.
|
|
Here "xxx" should of course be replaced by the respective library name.
|
|
|
|
The checks for each library grow organically to compensate for
|
|
various bugs in the libraries, pkg-config, etc. This is why we have
|
|
a separate macro for each library.
|
|
|
|
- NUT_CHECK_IPV6
|
|
|
|
Check for various features required to compile the IPv6 support.
|
|
dnl Check for various features required for IPv6 support. Define a
|
|
preprocessor symbol for each individual feature (HAVE_GETADDRINFO,
|
|
HAVE_FREEADDRINFO, HAVE_STRUCT_ADDRINFO, HAVE_SOCKADDR_STORAGE,
|
|
SOCKADDR_IN6, IN6_ADDR, HAVE_IN6_IS_ADDR_V4MAPPED,
|
|
HAVE_AI_ADDRCONFIG). Also set the shell variable nut_have_ipv6=yes
|
|
if all the required features are present. Set nut_have_ipv6=no
|
|
otherwise.
|
|
|
|
- NUT_CHECK_OS
|
|
|
|
Check for the exact system name and type.
|
|
This was only used in the past to determine the packaging rule to be
|
|
used through the OS_NAME variable, but may be useful for other purposes
|
|
in the future.
|
|
|
|
- NUT_REPORT_FEATURE(FEATURE, VALUE, VARIABLE, DESCRIPTION)
|
|
|
|
Schedule a line for the end-of-configuration feature summary. The
|
|
FEATURE is a descriptive string such that the sentence "Checking
|
|
whether to FEATURE" makes sense, and VALUE describes the decision
|
|
taken (typically yes or no). The feature is also reported to the
|
|
terminal.
|
|
|
|
Also use VARIABLE and DESCRIPTION for defining AM_CONDITIONAL and
|
|
AC_DEFINE (only if VALUE = "yes"). VARIABLE is of the form 'WITH_<NAME>'.
|
|
|
|
- NUT_REPORT(FEATURE, VALUE)
|
|
|
|
Schedule a line for the end-of-configuration feature summary, without
|
|
printing anything to the terminal immediately.
|
|
|
|
- NUT_PRINT_FEATURE_REPORT
|
|
|
|
Print out a list of the features that have been reported by
|
|
previous NUT_REPORT_FEATURE macro calls.
|
|
|
|
- NUT_ARG_WITH(FEATURE, DESCRIPTION, DEFAULT)
|
|
|
|
Declare a simple --with-FEATURE option with the given DESCRIPTION
|
|
and DEFAULT. Sets the variable nut_with_FEATURE.
|
