Desc: NUT-specific autoconf macros
File: macros.txt
Date: 27 December 2006
Auth: Peter Selinger <selinger@users.sourceforge.net>
The following NUT-specific autoconf macros are defined in the m4/
directory.
- Macro: NUT_TYPE_SOCKLEN_T
- Macro: NUT_TYPE_UINT8_T
- Macro: NUT_TYPE_UINT16_T
Check for the corresponding type in the system header files, and
#define a replacement if necessary.
- Macro: NUT_CHECK_LIBGD
- Macro: NUT_CHECK_LIBHAL
- Macro: NUT_CHECK_LIBNETSNMP
- Macro: NUT_CHECK_LIBSSL
- Macro: NUT_CHECK_LIBUSB
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.
- Macro: NUT_CHECK_HIDDEV
Check for the presence/location of Linux hiddev. If present, set
nut_linux_hiddev to the device path. If not present, set
nut_linux_hiddev="". This macro can be run multiple times, but will
do the checking only once.
- Macro: 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.
- Macro: NUT_REPORT_FEATURE(FEATURE, VALUE)
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.
- Macro: NUT_REPORT(FEATURE, VALUE)
Schedule a line for the end-of-configuration feature summary, without
printing anything to the terminal immediately.
- Macro: NUT_PRINT_FEATURE_REPORT
Print out a list of the features that have been reported by
previous NUT_REPORT_FEATURE macro calls.
- Macro: NUT_ARG_WITH(FEATURE, DESCRIPTION, DEFAULT)
Declare a simple --with-FEATURE option with the given DESCRIPTION
and DEFAULT. Sets the variable nut_with_FEATURE.
