Daniel Elstner e662d9e8e5 Build: Limit system features to C99 and POSIX
Use -std=c99 to try and enforce standard compliance.

Daniel Elstner 2d2240bb99 Build: Fix SR_CHECK_COMPILE_FLAGS
Do not put "no" into the flags if the check fails.

Daniel Elstner ba1c29dc22 Build: Reduce unnecessary config substitutions
Variable substitutions with a constant value may as well be
set directly in Makefile.am.

Daniel Elstner bc8ff24de6 Build: Leave LIBS alone during configure
Put the extra libraries into SR_EXTRA_LIBS instead of LIBS.
Create an SR_CHECK_LIBS macro to make that easy. Substitute
SR_EXTRA_LIBS into libsigrok.pc, too.

Daniel Elstner 4ed3d9b6db Build: Simplify driver dependency check 2015-08-24 20:15:36 +02:00
Daniel Elstner 2d143826b0 Build: Add private copy of C++11 check macro
Place a copy of ax_cxx_compile_stdcxx_11.m4 from the Autoconf
macro archive into our private m4/ directory. This is cleaner
than trying to parse M4 file versions etc. Plus, the macro is
now always available.

Daniel Elstner 0ab8386a5c Build: Prefer newer versions of libftdi and SWIG 2015-08-24 20:14:57 +02:00
Daniel Elstner 26b67f1141 Build: Use commas to separate missing dependencies
Beautify the output. Also fix the PyGObject test.
2015-08-24 20:14:48 +02:00
Daniel Elstner be21d81a15 Build: Reduce autogen.sh to a trivial stub
Use autoreconf instead of invoking the various Auto tools
separately. Get rid of the Darwin-specific guesswork -- it
does not make sense to handle this at the level of libsigrok.

People should set up their ACLOCAL_PATH themselves as appropriate
for their own system; just as they already need to set up various
other paths.

Daniel Elstner b84a733105 Build: Check for accepted compiler flags
Introduce the SR_CHECK_COMPILE_FLAGS macro and use it to check
for additional compiler flags. Put the accepted flags into the
separate substitution variable SR_EXTRA_CFLAGS.

With this and the preceding changes, bug #578 should now be fixed.
2015-08-24 20:12:47 +02:00
Daniel Elstner 1bb196e496 Build: Move package check macros to m4/sigrok.m4
Define generic macros for pkg-config dependency checks etc. in
m4/sigrok.m4, so they can be easily reused by downstream modules.
2015-08-24 20:10:18 +02:00
Daniel Elstner 4cf2f34f43 Build: Make compiler warnings configurable
Use the SR_ARG_ENABLE_WARNINGS macro to configure and check for
the availability of compiler warning flags. Maintain separate
sets of warning flags for C and C++.

The configure option --enable-warnings=[min|max|fatal|no] can
be used to set the compiler warning level for all languages.
The default level is "max".
2015-08-24 20:08:24 +02:00
Daniel Elstner 24138539c1 Build: Move custom Autoconf macros to separate file
Place custom Autoconf macros which other sigrok modules may
re-use into a separate file m4/sigrok.m4. Also, introduce new
macros for defining the package and library versions, and for
gathering compiler warning flags.

Daniel Elstner ea1d535145 Build: Place Autoconf macros into m4/ directory
This separates the M4 macros from the other cruft in autostuff/
to prepare for the introduction of custom macro files.

Daniel Elstner cb4d28efd1 Build: Do not omit first argument to m4_warn()
It seems that contrary to what the documentation says, leaving
the category argument to m4_warn() empty is not allowed. Use
the "unsupported" category for lack of a better choice.

Uwe Hermann aafcb3fe87 FreeBSD: Also check for swig3.0.
On FreeBSD (for example) the SWIG binary can also be called "swig3.0".

This fixes (together with the recent "swig2.0" addition) bug #557.
2015-08-19 15:44:43 +02:00
Daniel Elstner a9cb82ace2 Build: Get rid of recursive make invocations
Do not invoke $(MAKE) just to execute some clean rule.
This gets rid of the "jobserver unavailable" warnings.

Daniel Elstner 90420ef6bc Build: Tell setup.py where to find SWIG 2015-08-18 20:14:14 +02:00
Uwe Hermann 3f03ffaf2f FreeBSD: Also check for swig2.0 in addition to swig.
On FreeBSD (for example) the SWIG binary is called "swig2.0".

This fixes bug #557.

Uwe Hermann 731c01f248 FreeBSD: Fix compile/link error due to missing libusb_get_version().
The FreeBSD libusb-1.0 API implementation doesn't have libusb_get_version().
Use our CONF_LIBUSB_1_0_VERSION macro instead.

Daniel Elstner dbde3b6513 Build: Avoid $< in explicit rules
Although useful, makes other than GNU make do not like this.
Name the prerequisite explicitly instead, and circumvent any
VPATH substitution other makes may do.

Daniel Elstner da0763d096 Build: Skip C++ CFLAGS and LIBS check when disabled
It is not a good idea to invoke PKG_CHECK_MODULES with an empty
list of modules to check, so skip the invocation in that case.

Daniel Elstner b8b727e45f Build: Fix typo that broke the driver enable options 2015-08-18 18:20:50 +02:00
Daniel Elstner d37c7109bf Build: Make SR_DRIVER() handle dependencies
Turn the hardware driver dependency handling on its head, by
making SR_DRIVER() take a list of dependencies to check for.

Daniel Elstner 7c16e74d45 Build: Make dependency on git change more robust
It can sometimes happen that .git/HEAD or .git/refs/head/*, which
are added as config.status dependencies during configure, do not
exist anymore at build time.  For instance, when the current branch
is deleted after switching to a different one.

Wrap the dependencies inside $(wildcard ...) to avoid this problem.
Note that this is a GNU make feature.  However, it should be fine
as it is only used for git builds.  Even if a non-GNU make is used,
the construct will hopefully just expand to nothing.

Daniel Elstner 2cbde15198 Build: Properly namespace the version defines
Use the CONF_ prefix for the configured host define as well as
the various build-time version macros.
2015-08-16 18:53:32 +02:00
Daniel Elstner 1f61c22ff5 Build: Cleanup up and modernize autotools setup
Note that some --enable options of configure have become
--with or --without options.
2015-08-16 18:28:13 +02:00
Daniel Elstner c5f179a975 Build: Simplify the hardware driver selection
Replace DRIVER() and DRIVER2() by a single SR_DRIVER() macro.
Derive the names of shell variables and preprocessor defines
programatically to cut down on repetition.

Daniel Elstner 7e2cadd003 Add dist tarball to gitignore 2015-08-16 18:28:13 +02:00
Daniel Elstner 5a3e34285d setup.py: Do VPATH search for swig/enums.i
Also, in swig/classes.i include swig/enums.i rather than plain
enums.i, to guard against future name clashes.
2015-08-16 18:28:13 +02:00
Daniel Elstner cf5b338e07 Build: Depend on swig/enums.i where appropriate 2015-08-16 18:28:13 +02:00
Daniel Elstner bc81463bb8 enums.py: Place swig/enums.i into build directory 2015-08-16 18:28:13 +02:00
Daniel Elstner 122322a9ba Build: Do not distribute generated headers
version.h and enums.hpp are generated at build time and should
not be included in the distribution tarball.  This seems to have
triggered a weird error when doing a VPATH build of the dist
tarball.
2015-08-16 18:28:13 +02:00
Daniel Elstner 9ac018d0fc Build: Pass nostdinc option to automake
It seems automake automatically adds the directory containing
the generated version.h to the include path.  Use nostdinc to
disable default includes altogether.
2015-08-16 18:28:13 +02:00
Daniel Elstner b5f0731971 Build: Use angle brackets for enums.cpp include 2015-08-16 18:28:13 +02:00
Daniel Elstner 31ac7735ea Build: Distribute bindings sources
A couple of files referenced during the build were missing from
the distribution, causing a tarball build failure.
2015-08-16 18:28:13 +02:00
Daniel Elstner 8b2a184327 Build: Prefix directory to include of enums.hpp
This fixes a build problem due to the reduced include search paths
introduced by my recent changes.  Also fix a couple of other
includes to use angle brackets.
2015-08-16 18:28:13 +02:00
Daniel Elstner 7f289d14ec Build: Append git revision hash to version
Append the git revision hash to the libsigrok package version,
unless HEAD exactly matches a release tag.  Note that this does
not affect the version known to autoconf -- e.g. source tarballs
created by make dist will not receive a revision suffix.

Changes to git HEAD automatically trigger a reconfiguration.
Uncommitted changes do not, which is why I left out the -dirty
suffix.

Daniel Elstner b9eb8e1a8c Consistently use SR_PACKAGE_VERSION instead of VERSION 2015-08-16 18:28:13 +02:00
Daniel Elstner 27a2497dc2 Build: Delay expansion of $datadir in FIRMWARE_DIR
Make it so that $(datadir) is resolved at make time, as per
autotools recommendations.  Note that $datadir is not fully
resolved at configure time to begin with, i.e. part of it
already was evaluated at make time.
2015-08-16 18:28:13 +02:00
Daniel Elstner b2478a23db Build: Make version.h a configuration header
Use the proper tool for the job and make libsigrok/version.h
a secondary configuration header, so that autoconf's AC_DEFINE
machinery can be used to generate it.  Note that the header
template is still hand-written, enabling fine control of the
content.
2015-08-16 18:28:13 +02:00
Daniel Elstner 4960aeb035 tests: Include <libsigrok/libsigrok.h>
This matches the global style and avoids the "../" path
components.
