In commit b7b5d51, AC_CONFIG_MACRO_DIRS([m4]) was added to configure.ac,
which is the current proper way of including the m4 directory. However,
old versions of autoconf ignore it and need the -I m4 statement in
Makefile.am. Both the old and new way of indicating that the m4/
directory should be included can coexist.
This fixes some issues with the build system when building out of tree.
With this commit, it is now possible to do the following:
$ cd /tmp/build
$ /path/to/tinc/configure
$ make
This uses the output of "git describe" directly in configure.ac to
determine the version number to use, instead of hardcoding it.
With this change, current version information is completely removed
from the codebase itself, and is always fetched on-the-fly from git as
the single source of truth.
In order to ensure make dist always uses the current version number in
the contents of the packaged configure script as well as the package
name, a dependency is added to the dist target such that autoconf is
always run before dist to regenerate the version number. If this wasn't
the case, make dist would use the version number from when autoconf was
originally run, not the version number that make dist is running from.
That said, errors from that rule are ignored so that people can still
run make dist without a working autoconf.
In addition, the NEWS check is dropped, as it would then become annoying
because it would force make dist users to always have a line for the
current commit in the NEWS file.
This gets rid of the rest of the symbolic links. However, as a consequence, the
crypto header files have now moved to src/, and can no longer contain
library-specific declarations. Therefore, cipher_t, digest_t, ecdh_t, ecdsa_t
and rsa_t are now all opaque types, and only pointers to those types can be
used.
Apparently they were once necessary, but autoconf now includes them
automatically. Some of them are not used anymore, and this caused make dist to
fail.
- Added seperate file for connection list handling
- Updating everything to use connlist, meta and subnet files
- Removed dependency on libgmp
- Lots of other stuff...
