Use AC_CHECK_LIB macro to search for libusb rather than rely on
pkg-config. Preserve environment variables LIBUSB_CFLAGS and
LIBUSB_LIBS as user precious variables. Two features,
--with-xml-support and --enable-usrp still rely on pkg-config so only
invoke pkg-config when either or both of these features are selected.
Only the Winradio g313 model uses libdl so test for it only when
Winradio backend is enabled.
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.
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/
Use groff and ps2pdf to generate PDF documetation from the nroff
formatted man pages for the utilities in tests/ and include them in the
generated ZIP archive. Document the needed utilities and availability.
Removed README_VB as its info is now embedded in the build-VB.NET.sh
script and is output into a custom README file upon creation of the ZIP
archive.
Added README.scripts to document reason for the directory and included
scripts.
The scripts/ directory will contain helper scripts for building Hamlib
binary releases for Win32 and possibly other target platforms. EAch
script should be accompanied by a companion README file with information
on the script and build requirements.
Initial release of build-win32.sh for building Win32 DLLs and EXEs for
use with MS VC++.
