The SWIG 2.0.12 on my system bails out with a syntax error on the
"noexcept" keyword in C++11 code. Define "noexcept" to nothing (for
the SWIG parser only) to work around this problem.
The hard-coded location is bound to be wrong anyway. Instead, rely
on the new resource lookup code to find the firmware files in a
location relative to the library or executable.
The resource API provides a generic means for accessing resources
that are bundled with sigrok, such as device firmware files. Since
the manner of resource bundling is platform-dependent, users of
libsigrok may override the functions used to open, close and read
a resource. The default implementation accesses resources as files
located in one of the XDG data directories or a directory defined
at compile time.
This is set to | (or left empty) by SR_PROG_MAKE_ORDER_ONLY for
portability reasons, since not all Make implementations support
order-only prerequisites.
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.
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.
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.
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.
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".
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.
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.
It seems automake automatically adds the directory containing
the generated version.h to the include path. Use nostdinc to
disable default includes altogether.
Move the include flags for files in the source tree from
configure.ac to Makefile.am where they belong. Also use
AM_CPPFLAGS instead of CFLAGS/CXXFLAGS to make sure the
files in the build/source tree are always picked up first.
Also, remove the include/libsigrok sub-directory from the
search path, thereby making the <libsigrok/> prefix mandatory
when building libsigrok itself. This matches the convention
already imposed on users of the library.
