This change:
- Adds a check for the doxygen program to configure.
- Moves the Doxyfile from src/Doxyfile to doc/Doxyfile.in.
- Generates a doc/Doxyfile from doc/Doxyfile.in inserting
an absolute path to the source directory, so that it
also works when builddir != srcdir.
- Adds `make api` rule for running doxygen; it depends on
api/doxygen file which is never created to force the rule
to always run.
With Autoconf 2.60a, the default values of datadir, infodir, and
mandir refer to ${datarootdir}. If Makefile.config.in does not define
datarootdir, Autoconf detects this and expands ${datarootdir} when it
substitutes expressions like @datadir@, but it also outputs the
following warning:
config.status: creating Makefile.config
config.status: WARNING: /home/Kalle/src/elinks/Makefile.config.in seems to ignore the --datarootdir setting
According to a comment in config.status, "This hack should be removed
a few years after 2.60." So it seems best to prepare for that now by
defining datarootdir = @datarootdir@ in Makefile.config.in. Earlier
versions of Autoconf may leave that line unexpanded; but because the
makefiles do not directly refer to ${datarootdir}, there's no harm.
The configure script no longer recognizes "CONFIG_UTF_8=yes" lines
in custom features.conf files. They will have to be changed to
"CONFIG_UTF8=yes". This incompatibility was deemed acceptable
because no released version of ELinks supports CONFIG_UTF_8.
The --enable-utf-8 option was not renamed.
$(AM_CFLAGS) is one of the variables set by Automake, which ELinks no
longer uses. $(CPPFLAGS) should be used whenever the C preprocessor
is run, according to the GNU Coding Standards. (My build environment
does have an important -I option there.)
Either set CONFIG_SM_SCRIPTING in features.conf or pass to ./configure the
option --disable-sm-scripting. Now scripting is also enabled when needed
and not only if some other scripting backend is enabled.
Remove some remnants of SEE scripting backend.
