SWIG_init() returns void for Python 2.x and 'PyObject *' for Python 3.
Use an #if to handle both cases properly, otherwise the Python bindings
for either Python 2 or 3 will fail to build.
Python 3.x failure:
sigrok/core/classes_wrap.cpp: In function ‘PyObject* PyInit__classes()’:
sigrok/core/classes_wrap.cpp:59002:5: error: return-statement with no
value, in function returning ‘PyObject* {aka _object*}’ [-fpermissive]
return;

Python 2.x failure:

This was superfluous -- there is no need to be able to query the
last MQ(s) sent by the device, since they're already being sent
along with the measurements in analog packets.
Since there is also no way to change the MQ (that is done with the
buttons on the device), there is no need to even list the possible
MQs.
The need to make this a list no longer applies.
SR_T_MQ is thus a type consisting of a tuple with two elements: the first
item is the MQ (type G_VARIANT_TYPE_UINT32), and the second is the MQ
flags value (G_VARIANT_TYPE_UINT64).
After the packet has been passed through the transformation modules,
the transformed data is in packet_in but the following code uses
the packet variable which still points to the original input.
This fixes bug #631.
Make vxi.h the first #include in all affected files and #undef the
_POSIX_C_SOURCE macro in vxi.h.
This avoids various build issues on e.g. FreeBSD or Mac OS X where
setting _POSIX_C_SOURCE leads to the unavailability of certain types
such as u_long (as used in the VXI/RPC code).
Extend setup.py to allow environment variables to be set on the
command line. Use that functionality to replace the pkg-config
invocations with flags passed on from make. Suppress the annoying
-Wstrict-prototypes warning by overriding the OPT variable.
Also move the "cd bindings/python" from Makefile.am to setup.py
to side-step problems with "cd" in make rules.
This also fixes bug #628.
- SR_MQ_MASS: Mass, as measured by scales / balances.
- SR_UNIT_*: Various units of mass.
- SR_MQFLAG_UNSTABLE: A flag denoting that a value has not
yet stabilized (settled). E.g. when placing an object on a scale
it'll take a few moments until a stable reading is available.
Measurement values marked with SR_MQFLAG_UNSTABLE denote that they
are "unsettled", unstable values (not yet stabilized).
The absence of SR_MQFLAG_UNSTABLE denotes that the value is stable.
- SR_CONF_SCALE: A device class for weighing scales / balances.
This basically makes glibc expose the same set of features as
if gcc was invoked without any restricting -std=c* option. Unlike
_GNU_SOURCE however, it does not enable GNU-specific extensions.
So, with this macro defined the behavior of Linux with glibc
should match that of other platforms.
In order to avoid confusion of the flags-gathering pkg-config
result with the actual test for the availability of "check",
change the pkg-config output variable prefix from CHECK to TESTS.
This type consists of an array, with each item a two-member tuple,
representing an MQ/MQflags pair: the first item is the MQ (type
G_VARIANT_TYPE_UINT32), and the second is the MQ flags value
(G_VARIANT_TYPE_UINT64).
A GVariant of type SR_T_MQLIST can thus always represent more than
one MQ/MQflag pair.
The tables defined with this struct can now be used for information
on items other than config keys.
Functions to access these tables have been renamed sr_key_info_[name_]get.
These take an extra argument, keytype, which should be set to SR_KEY_CONFIG
to get the config key tables. Other key types will be added.
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.
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.
