linux - bitbake 期间出现“ fatal error : linux/compiler-gcc5. h:没有此类文件或目录”

Question

我正在尝试使用非 yocto 自定义源对配方运行 bitbake。使用 linux-yocto 源工作正常，但是当我尝试使用 yocto 项目文件提供的 linux-yocto-custom 框架文件时，我遇到了问题。

我的文件结构看起来有点像这样:

meta-test
|
.
.
.
+--recipes-kernel/
   |
   +--linux/
       |
       +--linux-yocto-custom_3.16.bb
       +--linux-yocto-custom/
          |
          +--defconfig

这是我修改后的骨架文件(linux-yocto-custom_3.16.bb):

inherit kernel
require recipes-kernel/linux/linux-yocto.inc
SRC_URI = "git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git;protocol=git;nocheckout=1;name=machine"
SRC_URI += "file://defconfig"
LINUX_VERSION ?= "3.16"
LINUX_VERSION_EXTENSION_append = "-custom"
SRCREV_test="19583ca584d6f574384e17fe7613dfaeadcdc4a6"
PV = "${LINUX_VERSION}+git${SRCPV}"
COMPATIBLE_MACHINE = "test"

这是错误日志:

我相信最相关的部分是上面日志的这一部分:

compiler-gcc.h:106:30: fatal error: linux/compiler-gcc5.h: No such file or directory

我真的很困惑，因为在构建“compiler-gcc5.h”期间生成了一个文件，位置为build/tmp/work/test-poky-linux/core-image-test/1.0-r0/rootfs/usr/src/kernel/include/linux/compiler-gcc5.h。这里发生了什么？在我看来，这个头文件在获取之前就被请求了，但我不知道如何解决这个问题。

由于您直接从 Linus 树中获取内核，因此 3.16 版本不支持使用 gcc5 进行构建。

如果您更改为从 git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git 获取，即稳定树，并更改为v3.16.7:

SRC_URI = "git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git;protocol=git;nocheckout=1;name=machine;branch=linux-3.16.y"
SRCREV_test = "d0335e4feea0d3f7a8af3116c5dc166239da7521"

那么您应该能够毫无问题地构建内核。
