编译问题1（audiomanager_7.0.bb的do_configure报错）：
错误：CMake Error at Plugins/PluginCommandInterfaceCAPI/cmake/CommonAPI.cmake:352 (message):
| Failed to generate files from FIDL:
手动执行一下：
$ commonapi-generator-linux-x86 -ll verbose -sk Default -d . /data/linux/hz_rs28_bm/sources/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/audiomanager/7.0-r1/audiomanager-7.0/Plugins/PluginCommandInterfaceCAPI/fidl/CommandInterface.fidl
-bash: /data/linux/hz_rs28_bm/sources/src/build/tools/commonapi_tool/commonapi-generator/commonapi-generator-linux-x86: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
解决（需要安装32位的glibc库和32位java jre环境）：
$ sudo yum install glibc.i686
$ sudo yum install java-1.8.0-openjdk.i686
$ sudo ln -s /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.i386/jre/bin/java /bin/java
$ java -version （保证是32位的java）
编译问题2（perl_5.20.0.bb的do_package报错）：
错误：ERROR: objcopy failed with exit code 256 (cmd was ‘arm-poky-linux-gnueabi-objcopy’ –only-keep-debug
… generate_uudmap: File format not recognized
解决（tar在1.29版本之后需要exclude在路径的前面）：
sources/meta/poky/bitbake/lib/bb/fetch2/bzr.py

修改成：
tar_flags = “–exclude=’.bzr’ –exclude=’.bzrtags'”

编译问题3（libunwind_1.1.bb的do_compile报错）：

编译问题3（qt5-app_1.0.bb的do_compile报错）：

编译问题4（makall报错）：
报错：./makall: line 169: mkisofs: command not found
解决：$ sudo yum install mkisofs
编译问题5（修改ac83xx_systemd_defconfig再编译时报错）：
报错：Applying patch remove-selinux-android.patch
patching file system/extras/ext4_utils/make_ext4fs.c
Hunk #1 FAILED at 62.

解决：
$ vi sources/meta/meta-atc/recipes-devtools/android-tools/android-tools_5.1.1.r37.bb
在里面做个假的do_patch()，bitbake会优先使用本bb文件的do_patch()函数。
do_patch(){
}
编译问题6（修改ac83xx_systemd_defconfig再编译时报错）：
报错：sources/build/tmp/work/armv7a-vfp-neon-poky-linux-gnueabi/qtbase/5.5.0+gitAUTOINC+c619d2daac-r0/git/src/corelib/tools/qregexp.cpp:3947:1: internal compiler error: in add_stores, at var-tracking.c:6000

编译问题8（修改ac83xx_systemd_defconfig再编译时报错）：
报错：python报错： ‘do_rootfs’, lineno: 17, function
Exception: CalledProcessError: Command ‘[‘du’, ‘-ks’, …
解决： 没有实际问题，重新编译一次即可，可能是机器太忙导致超时，或者某个命令执行不成功。
