Astyle is a code formatting utility that can quickly reformat a source
file based on the settings of its configuration file. The added
configuration file will format to a style mostly consistent with the
Linux Kernel Style guide:
https://www.kernel.org/doc/Documentation/CodingStyle
While conformance to this document is not the goal, it supplies a
reasonable set of guidelines to be used in Hamlib.
No longer depend on libltdl from the libtool package. The
winradio/linradio/wg313api backend still depends on libdl, but since it
is only compiled on POSIX, it will use the POSIX supplied libdl.
Update documentation to remove references to libltdl.
Previously, invoking autogen.sh would create symbolic links to needed
Autotools files in the tree only when working from a Git checkout
(source distributions have the files included). Consideration of this
included the possibility of bugs if the Autotools packages were upgraded
on the developer's system that strange bugs could result. Copying the
files means the tree is self contained until the next time autoreconf or
autogen.sh is run.
The top level Makefile.am included the variable $(subdirs) in both
SUBDIRS and DIST_SUBDIRS assignments. While this variable may contain a
useful value, it is undocumented in the manuals. Relying on it may
result in some directory being ommitted or other changes in the future,
so removing it from the assignments.
Use the libtool link mode argument '-version-info' to set the Hamlib 3
ABI to be compatible with Hamlib 1.2 ABI. As the current ABI has not
been changed or removed, we should be able to maintain backward
compatibility. The libtool docs state that so long as the ABI is only
added to, backward compatibility should be maintained.
My idea here is to be able to have presently compiled programs be able
to use binary libraries of Hamlib 3 without recompiling. So far I have
tested this locally on Linux and Windows. More testing is welcome.
Initializing libltdl is now done by the LTDL_INIT macro in configure.ac.
This now creates a libltdl directory in the tree (not tracked in Git)
when autoreconf is run. The downside is that this complicates the build
a little bit with the advantage that the build can now take place on a
system that does not have libltdl-dev installed as Hamlib will build on
such systems by passing the '--with-included-ltdl' flag to the configure
script. In particular, this simplifies the build on Linux for the mingw32
host by not having to run libtoolize manually and assures that libltdl
is built with the same build and host architectures as Hamlib.
Now check if '--with-included-ltdl' has been passed to configure and if
not, only then test for the presence of an installed ltdl.h.
Commented out AM_MAINTAINER_MODE macro. It is recommended by the
Automake manual that this macro and its configure options not be used as
the Autotools system is designed to regenerate its files. Let me know
if this is problem as it can be reversed easily enough. The autogen.sh
script no longer passes the '--enable-maintainer-mode' option to
configure when bootstrapping the build system from Git.
Minor edits in configure.ac to improve readability.
Updated build-win32 files in scripts/
Clean up leftover file from bundled libtool. The autoconf script will
provide a symlink to the system installed install-sh for the version of
automake installed.
