This class adds a step to the package generation process that sanity checks the packages generated by the OpenEmbedded build system. A range of checks are performed that check the build's output for common problems that show up during runtime. Distribution policy usually dictates whether to include this class.
You can configure the sanity checks so that specific test failures either raise a warning or
an error message.
Typically, failures for new tests generate a warning.
Subsequent failures for the same test would then generate an error message
once the metadata is in a known and good condition.
You use the WARN_QA variable to specify tests for which you
want to generate a warning message on failure.
You use the ERROR_QA variable to specify tests for which you
want to generate an error message on failure.
The following list shows the tests you can list with the WARN_QA
and ERROR_QA variables:
ldflags:
Ensures that the binaries were linked with the
LDFLAGS options provided by the build system.
If this test fails, check that the LDFLAGS variable
is being passed to the linker command.
useless-rpaths:
Checks for dynamic library load paths (rpaths) in the binaries that
by default on a standard system are searched by the linker (e.g.
/lib and /usr/lib).
While these paths will not cause any breakage, they do waste space and
are unnecessary.
rpaths:
Checks for rpaths in the binaries that contain build system paths such
as TMPDIR.
If this test fails, bad -rpath options are being
passed to the linker commands and your binaries have potential security
issues.
dev-so:
Checks that the .so symbolic links are in the
-dev package and not in any of the other packages.
In general, these symlinks are only useful for development purposes.
Thus, the -dev package is the correct location for
them.
Some very rare cases do exist for dynamically loaded modules where
these symlinks are needed instead in the main package.
debug-files:
Checks for .debug directories in anything but the
-dbg package.
The debug files should all be in the -dbg package.
Thus, anything packaged elsewhere is incorrect packaging.
arch:
Checks the Executable and Linkable Format (ELF) type, bit size and endianness
of any binaries to ensure it matches the target architecture.
This test fails if any binaries don't match the type since there would be an
incompatibility.
Sometimes software, like bootloaders, might need to bypass this check.
debug-deps:
Checks that -dbg packages only depend on other
-dbg packages and not on any other types of packages,
which would cause a packaging bug.
dev-deps:
Checks that -dev packages only depend on other
-dev packages and not on any other types of packages,
which would be a packaging bug.
pkgconfig:
Checks .pc files for any
TMPDIR/WORKDIR paths.
Any .pc file containing these paths is incorrect
since pkg-config itself adds the correct sysroot prefix
when the files are accessed.
la:
Checks .la files for any TMPDIR
paths.
Any .la file continaing these paths is incorrect since
libtool adds the correct sysroot prefix when using the
files automatically itself.
desktop:
Runs the desktop-file-validate program against any
.desktop files to validate their contents against
the specification for .desktop files.
