12 When building a recipe, the OpenEmbedded build system performs
13 various QA checks on the output to ensure that common issues are
14 detected and reported.
15 Sometimes when you create a new recipe to build new software,
16 it will build with no problems.
17 When this is not the case, or when you have QA issues building any
18 software, it could take a little time to resolve them.
19 </para>

21 <para>
22 While it is tempting to ignore a QA message or even to
23 disable QA checks, it is best to try and resolve any
24 reported QA issues.
25 This chapter provides a list of the QA messages and brief explanations
26 of the issues you could encounter so that you can properly resolve
27 problems.

31 The next section provides a list of all QA error and warning
32 messages based on a default configuration.
33 Each entry provides the message or error form along with an
34 explanation.

133 While these paths will not cause any breakage, they do waste
134 space and are unnecessary.

215 The specified file may have been installed into an incorrect

217 For example, this test will catch recipes that install

219 <filename>${base_libdir}</filename> is "lib32".
220 Another example is when recipes install
221 <filename>/usr/lib64/foo.so</filename> when
222 <filename>${libdir}</filename> is "/usr/lib".
223 False positives occasionally exist.
224 For these cases add "libdir" to
225 <link linkend='var-INSANE_SKIP'><filename>INSANE_SKIP</filename></link>

279 By default, the OpenEmbedded build system checks the
280 Executable and Linkable Format (ELF) type, bit size, and
281 endianness of any binaries to ensure they match the
282 target architecture.
283 This test fails if any binaries do not match the type since
284 there would be an incompatibility.
285 The test could indicate that the wrong compiler or compiler
286 options have been used.
287 Sometimes software, like bootloaders, might need to
288 bypass this check.
289 If the file you receive the error for is firmware
290 that is not intended to be executed within the target
291 operating system or is intended to run on a separate
292 processor within the device, you can add "arch" to
293 <link linkend='var-INSANE_SKIP'><filename>INSANE_SKIP</filename></link>
294 for the package.
295 Another option is to check the
296 <link linkend='ref-tasks-compile'><filename>do_compile</filename></link>
297 log and verify that the compiler options being used
298 are correct.

942 Produced binaries have already been stripped prior to the
943 build system extracting debug symbols.
944 It is common for upstream software projects to default to
945 stripping debug symbols for output binaries.
946 In order for debugging to work on the target using
947 <filename>-dbg</filename> packages, this stripping must be
948 disabled.
949 Depending on the build system used by the software being
950 built, disabling this stripping could be as easy as
951 specifying an additional configure option.
952 If not, disabling stripping might involve patching
953 the build scripts.
954 <note>
955 Disabling stripping here does not mean that the final
956 packaged binaries will be unstripped.
957 Once the OpenEmbedded build system splits out debug
958 symbols to the <filename>-dbg</filename> package,
959 it will then strip the symbols from the binaries.
