Bitbake 配方缺少 do_patch 任务

如何解决Bitbake 配方缺少 do_patch 任务

我有一个内核模块的基本配方文件，如下所示：

SUMMARY = "my package"
AUTHOR = "me"
PRIORITY = "required"
PR = "r1"
SECTION = "base"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI = "file://foo_${PV}.tgz"
SRC_URI += " file://foo.patch;patch=1;apply=yes "

inherit module

EXTRA_OEMAKE += "PREFIX=${D}"
EXTRA_OEMAKE_append_task-install = " -C ${STAGING_KERNEL_DIR} M=${S}"
EXTRA_OEMAKE += "KERNELDIR=${STAGING_KERNEL_DIR}"

我为源代码创建了一个补丁：foo.patch 并将其放置在 files 目录中。令人困惑的部分是我没有收到任何错误，只是没有应用补丁。 do_fetch 和 do_unpack 似乎找到补丁文件就好了，即如果我导航到工作目录，我会找到补丁文件。

基于一些搜索，我尝试了向补丁文件行添加各种属性，但收效甚微。例如：

SRC_URI += " file://foo.patch;patch=1;apply=yes;pnum=0 "

SRC_URI += " file://foo.patch "

SRC_URI += " file://foo.patch;patch=1;apply=yes;patchdir=${WORKDIR} "

我注意到的一件事是 bitbake -c listtasks foo 的输出：

NOTE: Executing RunQueue Tasks
do_build                   Default task for a recipe - depends on all other normal tasks required to 'build' a recipe
do_buildclean              Call 'make clean' or equivalent in 
do_checkuri                Validates the SRC_URI value
do_checkuriall             Validates the SRC_URI value for all recipes required to build a target
do_clean                   Removes all output files for a target
do_cleanall                Removes all output files,shared state cache,and downloaded source files for a target
do_cleansstate             Removes all output files and shared state cache for a target
do_compile                 Compiles the source in the compilation directory
do_configure               Configures the source by enabling and disabling any build-time and configuration options for the software being built
do_devpyshell              Starts an interactive Python shell for development/debugging
do_devshell                Starts a shell with the environment set up for development/debugging
do_fetch                   Fetches the source code
do_fetchall                Fetches all remote sources required to build a target
do_install                 Copies files from the compilation directory to a holding area
do_listtasks               Lists all defined tasks for a target
do_make_scripts            
do_package                 Analyzes the content of the holding area and splits it into subsets based on available packages and files
do_package_qa              Runs QA checks on packaged files
do_package_write_rpm       Creates the actual RPM packages and places them in the Package Feed area
do_packagedata             Creates package metadata used by the build system to generate the final packages
do_populate_lic            Writes license information for the recipe that is collected later when the image is constructed
do_populate_sysroot        Copies a subset of files installed by do_install into the sysroot in order to make them available to other recipes
do_prepare_recipe_sysroot  
do_unpack                  Unpacks the source code into a working directory

do_patch 没有列出！？这对我来说似乎不正确，但是我的补丁在处理到 ${WORKDIR} 后又没有被应用，而且我没有收到任何错误。我是否需要继承某个类来获取 do_patch 任务？临时目录中也没有 log.do_patch。有什么想法吗？

解决方法

我仍然不确定为什么我的食谱没有“do_patch”任务，但作为一种解决方法，我创建了一个似乎已经成功的自定义任务。我已将以下内容附加到我的食谱中：

do_mypatch(){
    patch ${WORKDIR}/foo.c < ${WORKDIR}/foo.patch
}

addtask mypatch before do_compile

为了验证：我执行了 bitbake -c listtasks foo。这是输出：

注意我的新自定义任务存在：do_mypatch

如果有人可以评论或知道为什么我的食谱没有得到 do_patch 任务的答案，请提供。
