1. Fix configure.ac tcp.h header and keepalive constant checks and report during ./configure the keepalive support that was detected (none, basic or full). 2. #include the correct tcp.h header in hstdinc.h 3. Issue warning message at build time (during make) when full keepalive support is missing or partial. 4. Report partial or missing keepalive build support via version.c "With" and "Without" messages. 5. Issue error or warning in both impl.c as well as in 'conkpalv' command/statement processing function when keepalive support is either missing or only partially supported. Same for the 2703 device 'ka=' option too. 6. Enhance set_socket_keepalive function to let the caller know not only about failures but also about partial-only successes (so they can be reported). 7. Fix the bad setsockopt call in the Linux version of the set_socket_keepalive function that was using the wrong value, which was at the heart of the problem. (Note: setsockopt was returning "success" anyway even though it had actually failed! [to accomplish anything].) 8. Introduce new get_socket_keepalive function to allow retrieval and reporting of current keepalive settings for a given socket. 9. Manually maintain socket keepalive values for Windows builds so it too can support retrieval of current values via new get_socket_keepalive function. (see comments in w32util.c "get_socket_keepalive" function!) 10. Minor HTML documentation edits.

# AC_LIB_LTDL
|
|
#
|
|
# Even though libltdl is installed together with libtool, you may wish
|
|
# to include libltdl in the distribution of your package, for the convenience
|
|
# of users of your package that don't have libtool or libltdl installed.
|
|
#
|
|
# The most simplistic way to add libltdl to your package is to copy the
|
|
# source files, 'ltdl.c' and 'ltdl.h', to a source directory withing your
|
|
# package and to build and link them along with the rest of your sources.
|
|
#
|
|
# To do this, you must add a call to the 'AC_LIB_LTDL' macro to your package's
|
|
# 'configure.in' to perform the required configure time checks in order that
|
|
# 'ltdl.o' is built correctly.
|
|
#
|
|
# This method does have its problems though: if you try to link the package
|
|
# binaries with an installed libltdl, or a library which depends on libltdl,
|
|
# you may have problems with duplicate symbol definitions.
|
|
#
|
|
# In order to enable this flavor of libltdl, you should add the line
|
|
# 'AC_LIBLTDL_CONVENIENCE' to your `configure.in', before 'AC_PROG_LIBTOOL'.
|
|
#
|
|
# In order to select the installable version of libltdl, you should add a
|
|
# call of the macro 'AC_LIBLTDL_INSTALLABLE' to your 'configure.in' before
|
|
# 'AC_PROG_LIBTOOL'. This macro will check whether libltdl is already
|
|
# installed and, if not, request the libltdl embedded in your package to be
|
|
# built and installed.
|
|
#
|
|
# Whatever macro you use, it is up to you to ensure that your 'configure.in'
|
|
# will configure libltdl, using 'AC_CONFIG_SUBDIRS', and that your 'Makefile's
|
|
# will start sub-makes within libltdl's directory, using automake's SUBDIRS,
|
|
# for example. Both macros define the shell variables LIBLTDL, to the link flag
|
|
# that you should use to link with libltdl, and LTDLINCL, to the preprocessor
|
|
# flag that you should use to compile with programs that include 'ltdl.h'. It
|
|
# is up to you to use 'AC_SUBST' to ensure that this variable will be available
|
|
# in 'Makefile's, or add them to variables that are 'AC_SUBST'ed by default,
|
|
# such as LIBS and CPPFLAGS.
|
|
#
|
|
# So, when you want to link a program with libltdl, be it a convenience,
|
|
# installed or installable library, just compile with '$(LTDLINCL)' and link
|
|
# it with '$(LIBLTDL)', using libtool.
|
|
#
|
|
# You should probably also add 'AC_LIBTOOL_DLOPEN' to your 'configure.in' before
|
|
# 'AC_PROG_LIBTOOL', otherwise libtool will assume no dlopening mechanism is
|
|
# supported, and revert to dlpreopening, which is probably not what you want.
|
|
#
|
|
# The following example shows you how to embed the convenience libltdl
|
|
# in your package. In order to use the installable variant just replace
|
|
# 'AC_LIBLTDL_CONVENIENCE' with 'AC_LIBLTDL_INSTALLABLE'. We assume that libltdl
|
|
# was embedded using 'libtoolize --ltdl':
|
|
#
|
|
# configure.in:
|
|
#
|
|
# ...
|
|
# dnl Enable building of the convenience library
|
|
# dnl and set LIBLTDL accordingly

|
# AC_LIBLTDL_CONVENIENCE

# default, the GCC 3.3 preprocessor conforms to the

# ISO C standard. Using the -tradtional-cpp option
