2019-07-04libcamera: Auto generate version informationKieran Bingham
Generate a version string, and provide a global string object which allows applications to interrogate the current libcamera version information. The version header is automatically updated by meson on each build. The string roughly follows the semver [0] conventions of major.minor.patch-label as a value. [0] https://semver.org/ A script (utils/gen-version.sh) is provided which is modelled upon the processing from autoconf's git-version-gen. The gen-version.sh script will look for tags in the form vX.Y as starting points for the version string. While the repository does not have any matching tags, v0.0 will be assumed, resulting in versions with both major and minor being set to '0', and the patch count resulting from the number of patches in the history to that point. Finally, a uniquely identifying shortened hash is provided from git: v0.0.509+0ec0edf7 Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
2019-06-19meson: Link against libc++ with compiling with clangLaurent Pinchart
libc++ is used by Chrome OS, and likely as well by other environments based on clang. Using it by default if available when compiling with clang will help extending the compile-testing coverage. The drawback is that issues specific to clang with libstdc++ will not be caught as easily, but based on the experience with clang so far, code compiling correctly with gcc/libstdc++ has failed with clang due to either clang-specific or libc++-specific behaviour, never due only to the combination of clang with libstdc++.

2019-04-27libcamera: Make libudev optionalLaurent Pinchart
libcamera depends on libudev for device enumeration. It is however useful to allow building documentation without requiring the dependency to be installed. Make the libudev dependency optional and compile the udev-based device enumerator out when libudev is not present. Note that while libcamera will compile without libudev, it will not be able to enumerate devices. A sysfs-based device enumerator is planned as a fallback but not implemented yet.

2019-04-26meson: check if secure_getenv() is presentGiulio Benetti
Not all libc make secure_getenv() available, this could lead to build failure on certain build systems. Check if secure_getenv() is available and emit #define HAVE_SECURE_GETENV to config.h Include config.h to every c/c++ file during building by adding `-include config.h` to project arguments for both c and c++.

2019-03-20meson: Provide options to disable test/docsKieran Bingham
It can be desirable to disable the compilation and processing of both the test suite and documentation for use cases such as packaging to an embedded target. Provide a new meson_options.txt file to allow disabling either or both of the tests and documentation components of libcamera. These options can be provided at the initial configuration time, for example: meson build -Dtests=false -Ddocumentation=false or by reconfiguring an existing build tree: cd build meson configure -Ddocumentation=false meson configure -Dtests=false Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>

Remove our custom declarations for cpp_std=c++11, -Wall, -Wextra and -Werror, instead prefering to use the built-in default_option parameters from meson. Our custom compiler flags (such as -Wno-unused-parameter) are maintained.

2019-01-01meson: Shorten project descriptionKieran Bingham
The project description is really the project name. The extraneosly long string gets printed at the test runner prefixed to the suite. As such it should really be the shortened simple project name.

2018-12-12Documentation: Generate source code documentation using DoxygenLaurent Pinchart
Extend the documentation build system to automatically generate documentation from source code using Doxygen. This is currently separate from the sphinx documentation, and should be integrated using the breathe (and possibly exhale) extensions. As the Documentation/meson.build file needs to reference the variables holding the source files, move the Documentation directory to the end of the subdirs() in the top-level meson.build.

2018-12-06Overhaul the directory structureLaurent Pinchart
In order to match the directory structure of traditional projects, rename the top-level lib/ directory to src/libcamera/. Other libraries developed as part of the project will later find a home in src/. Split the libcamera header files in three categories: public headers describing the public API in include/libcamera/, internal headers describing the internal API in src/libcamera/include/, and private headers local to one or a small number of compilation units along the corresponding .cpp files. As no internal header exists yet the src/libcamera/include/ directory is created empty as the build system would fail otherwise.
