yocto編譯內核命令
❶ Yocto編譯傑發或MTK的linux或android時的幾個問題
編譯問題1（audiomanager_7.0.bb的do_configure報錯）：
錯誤：CMake Error at Plugins/PluginCommandInterfaceCAPI/cmake/CommonAPI.cmake:352 (message):
| Failed to generate files from FIDL:
手動執行一下：
$ 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
解決（需要安裝32位的glibc庫和32位java jre環境）：
$ 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 （保證是32位的java）
編譯問題2（perl_5.20.0.bb的do_package報錯）：
錯誤：ERROR: obj failed with exit code 256 (cmd was 『arm-poky-linux-gnueabi-obj』 –only-keep-debug
… generate_uudmap: File format not recognized
解決（tar在1.29版本之後需要exclude在路徑的前面）：
sources/meta/poky/bitbake/lib/bb/fetch2/bzr.py
tar_flags = 「–exclude 『.bzr』 –exclude 『.bzrtags'」
修改成：
tar_flags = 「–exclude=』.bzr』 –exclude=』.bzrtags'」
sources/meta/poky/bitbake/lib/bb/fetch2/cvs.py
tar_flags = 「–exclude 『CVS'」
修改成：

–exclude=miniperl –exclude=generate_uudmap –exclude=patches * | ( cd ${D}${PTEST_PATH} && tar -x )
編譯問題3（libunwind_1.1.bb的do_compile報錯）：
錯誤：make[1]: latex2man: Command not found
解決：
$ sudo yum install texlive-tetex
$ sudo rpm -ivh ~/latex2man-1.18-2.noarch.rpm
編譯問題3（qt5-app_1.0.bb的do_compile報錯）：
錯誤（有一批類似的錯誤）：ld: cannot find -lgtest
解決：
$ vi atc_linux/application/btate/btate.pro
equals(MY_BUILD_SYSTEM, atc) {
LIBS += -L $(DA_LIBDIR)/lib -lgtest -lpthread -lbluetoothclient -lglobalbus -lappobj -lapputils

編譯問題4（makall報錯）：
報錯：./makall: line 169: mkisofs: command not found
解決：$ sudo yum install mkisofs
編譯問題5（修改ac83xx_systemd_defconfig再編譯時報錯）：
報錯：Applying patch remove-selinux-android.patch
patching file system/extras/ext4_utils/make_ext4fs.c
Hunk #1 FAILED at 62.
1 out of 1 hunk FAILED — rejects in file system/extras/ext4_utils/make_ext4fs.c
解決：
$ vi sources/meta/meta-atc/recipes-devtools/android-tools/android-tools_5.1.1.r37.bb
在裡面做個假的do_patch()，bitbake會優先使用本bb文件的do_patch()函數。
do_patch(){
}
編譯問題6（修改ac83xx_systemd_defconfig再編譯時報錯）：
報錯：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
解決：
$ cd sources/meta/poky/meta/recipes-devtools/gcc/gcc-4.9/
$ wget http://openlinux.windriver.com/overc/sources/core2_64/gcc-4.9.2-r0.1/0062-gcc-var-tracking.c-backport-from-gcc-trunk-r212178.patch

Content-Transfer-Encoding: 8bit
resolves a bug seen on cortexa8 building qt5 libraries.

* var-tracking.c (add_stores): Return instead of asserting if old
and new values for conditional store are the same.

編譯問題7（修改ac83xx_systemd_defconfig再編譯時報錯）：
報錯：libevdev/1.2.2-r0/libevdev-1.2.2/test/test-main.c:24:19: fatal error: check.h: No such file or directory
解決：

編譯問題8（修改ac83xx_systemd_defconfig再編譯時報錯）：
報錯：python報錯： 『do_rootfs』, lineno: 17, function
Exception: CalledProcessError: Command 『[『』, 『-ks』, …
解決： 沒有實際問題，重新編譯一次即可，可能是機器太忙導致超時，或者某個命令執行不成功。
編譯問題9（preuboot編譯工具問題）：
報錯：make: armv7a-mediatek451_001_vfp-linux-gnueabi-gcc: Command not found
解決：
