Yocto编译杰发或MTK的linux或android时的几个问题

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

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：

tar_flags = “–exclude=’CVS'”

sources/meta/poky/bitbake/lib/bb/fetch2/repo.py

tar_flags = “–exclude ‘.repo’ –exclude ‘.git'”

修改成：

tar_flags = “–exclude=’.repo’ –exclude=’.git'”

sources/meta/poky/bitbake/lib/bb/fetch2/svn.py

tar_flags = “–exclude ‘.svn'”

修改成：

tar_flags = “–exclude=’.svn'”

sources/meta/poky/meta/recipes-devtools/quilt/quilt-0.63.inc

        tar -c –exclude=\*.in compat/ | ( cd ${D}${PTEST_PATH} &&tar -xf – )

        tar -c –exclude=mail.test –exclude=delete.test test/ | ( cd ${D}${PTEST_PATH} &&tar -xf – &&chmod 777 test)

sources/meta/poky/meta/recipes-extended/sed/sed-4.2.2/sed-add-ptest.patch

+       cd $(BUILDDIR)tar -cf – $(TESTDIR) –exclude *.o | ( cd $(DESTDIR) &&tar -xf – )

修改成：

+       cd $(BUILDDIR)tar -c –exclude=*.o $(TESTDIR) | ( cd $(DESTDIR) &&tar -xf – )

sources/meta/poky/meta/recipes-support/attr/acl.inc

tar -cf – test/ –exclude nfs | ( cd ${D}${PTEST_PATH} &&tar -xf – )

修改成：

       tar -cf – * –exclude \*.o –exclude libperl.so –exclude Makefile –exclude makefile –exclude hostperl \

               –exclude miniperl –exclude generate_uudmap –exclude patches | ( cd ${D}${PTEST_PATH} &&tar -xf – )

修改成：

        tar -c –exclude=\*.o –exclude=libperl.so –exclude=Makefile –exclude=makefile –exclude=hostperl \

                –exclude=miniperl –exclude=generate_uudmap –exclude=patches * | ( cd ${D}${PTEST_PATH} &&tar -x )

编译问题3（libunwind_1.1.bb的do_compile报错）：

错误：make[1]: latex2man: Command not found

解决：

$ sudo yum install texlive-tetex

$ sudo rpm -ivh ~/latex2man-1.18-2.noarch.rpm

编译问题3（qt5-app_1.0.bb的do_compile报错）：

错误（有一批类似的错误）：ld: cannot find -lgtest

解决：

$ vi atc_linux/application/btate/btate.pro

equals(MY_BUILD_SYSTEM, atc) {

    LIBS += -L $(DA_LIBDIR)/lib -lgtest -lpthread -lbluetoothclient -lglobalbus -lappobj -lapputils

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.

1 out of 1 hunk FAILED — rejects in file system/extras/ext4_utils/make_ext4fs.c

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

解决：

$ 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

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.

编译问题7（修改ac83xx_systemd_defconfig再编译时报错）：

报错：libevdev/1.2.2-r0/libevdev-1.2.2/test/test-main.c:24:19: fatal error: check.h: No such file or directory

DEPENDS += “libcheck”

SRC_URI = “ http://www.freedesktop.org/software/libevdev/ ${BP}.tar.xz”

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。

编译问题9（preuboot编译工具问题）：

报错：make: armv7a-mediatek451_001_vfp-linux-gnueabi-gcc: Command not found

1.Yocto简介：

Yocto 是一个开源社区，它通过提供模版、工具和方法帮助开发者创建基于linux内核的定制系统，支持ARM, PPC, MIPS, x86 (32 &64 bit)硬件体系架构。

2.Yocto定制准备工作

（1）确保电脑能联网，并且有100G的空闲，电脑配置不低于4核

（2）获取yocto脚本：$git clone git://git.yoctoproject.org/poky

（3）获取硬件相关层：$git clone git://git.yoctoproject.org/meta-intel.git

（4）关于yocto的帮助：http://www.yoctoproject.org/documentation

3.开始搭建环境

（1）$source poky/oe-init-build-env xxx

xxx$cd conf

xxx/conf$ vim bblayers.conf

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf

# changes incompatibly

LCONF_VERSION = "4"

BBFILES ?= ""

BBLAYERS ?= " \

/hda5/hmi/x86/yocto/poky/meta \

/hda5/hmi/x86/yocto/poky/meta-yocto \

/hda5/hmi/x86/yocto/poky/meta-intel \

/hda5/hmi/x86/yocto/poky/meta-intel/meta-crownbay \

（2）修改local.conf

xxx/conf$ vim local.conf

#MACHINE ??= "qemux86"

MACHINE ??= "crownbay"

4.开始编译

注：(官方下载的只是脚本，yocto一边下载一边编译所以很慢而且还受资源下载限制和电脑配置，下载的文件在工作目录中的downloads中，第一次下载后保存好downloads以后就方便了)

（1）配置内核

xxx$ bitbake linux_yocto -c menuconfig

（2）定制微型yocto

xxx$ bitbake core-image-minimal

（3）定制桌面型yocto

xxx$ bitbake coure-image-sato

（4） hob config

xxx$ hob

可以在图形化界面中方便的定制系统。
