Also reorder its call in configure.ac which now allows the PYTHON_VERSION
environment variable to be recognized and processed correctly by the
build system.
Correctly add PYTHON_LIBS (correct ouput variable of AX_PYTHON_DEVEL) to the
Makefile for the Python bindings.
Update README.python for use of PYTHON_VERSION.
Clean up various left over commented lines from dlopen to single
libhamlib transition. Remove unneeded configure variables.
Correct minor inconsistencies in Makefile.am files.
Define a new variable, READLINE_LIBS, so that only programs that offer
Readline support are linked against it.
Fix various compilation warnings and errors in test files revealed with
'make check' on MinGW.
Define rig and rotor backends to (mostly) be built in alphabetical
order.
MinGW does not natively support the POSIX sleep() function so we have
had an override that was a part of the GR_PWIN32 macro and included in
the generated config.h file. When compiling for Windows on POSIX using
MinGW, Autotools will detect sleep() and set HAVE_SLEEP which prevented
the substitution from being included in the source. Adding a test for
_WIN32 (set by MinGW's gcc) then caused a warning from src/network.c on
POSIX about winsock2.h needing to be included before windows.h. As
config.h needed to be included first, the solution to break out the
substitution that includes windows.h into its own file. This patch
provides that solution and allows the code to compile cleanly on POSIX,
using MinGW on both POSIX and Windows, and on Cygwin.
Building libltdl recursively with MinGW failed with an error of "sleep"
being redefined. Commenting out the sleep() definition in config.h.in
resulted in libtdl compiling but a linker failure in libyaesu as
"_sleep" was not defined.
A bit of searching reveals that the MS Windows API does not include
"sleep" and MinGW does not include it either, hence the definition in
gr_pwin32.m4 from the GNU Radio project. Uopn finding a MinGW User
thread from 2007 that discussed this very issue, the following message
hinted that using a CPP #define to wrap Windows Sleep() may work:
http://mingw.5.n7.nabble.com/Help-where-is-the-C-language-sleep-function-tp8921p8925.html
And indeed it seems to. Compilation is now clean with recursive libltdl
and the rest of Hamlib, but does it work?
Use ax_pkg_swig.m4 from the GNU Autoconf Macro Archive as it is actively
maintained and update configure.ac accordingly.
Moved the Swig test to the bindings section of configure.ac.
Refactored the logic of the Swig test.
Updated ax_python_devel.m4 to latest version in the Autoconf Macro
Archive (removes two email addresses, not other changes).
Removed aclocal-include.m4 and lf_warnings.m4 as they were not being
used any longer.
Update macros definitions in macros/Makefile.am to recent additions and
deletion of the local macro files.
Cleaned up M4sh syntax for variable quoting, replaced shell 'if'
conditionals with M4sh AS_IF macro and shell 'case' with AS_CASE macro.
Properly quoted macro variables. Added comments to configure.ac
describing actions, commented out obsolete macros, commented obsolecent
macros, and added comments for major sections.
Corrected a Mingw linker error on the .EXE files adding
'--enable-auto-import' to their LD flags. Testing this commit on win32
shows that rigctld is now working properly. Will need to port this to
the Stable branch and test.
Replaced older local macros with newer replacements from GNU Autoconf
archive.
Using the -Wall switch to autoconf/autoreconf revealed a number of
obsolete macros. At the moment, offending macros have been commented
out using 'dnl'. They will be removed at some later date.
- autogen.sh: never downgrade our bundled libltdl/ (only run libtoolize if
system version is newer than our bundled version).
- autofixer.sh: script removed as libtool 1.x is no longer allowed.
- configure.ac: (not enabled) optional setting to deprecate embedded libltdl/.
