如何解决如何在 Yocto bitbake 编译步骤中剥离和 objcopy 构建的 .so 文件?
这个问题来自:
Do I need to edit the .patch files needed for building mdns 878.200.35 in Yocto?
这将通过几个帖子追溯到相当大的背景。
由于“mDNS”似乎在我的目标中工作,并且配方将 libdns_sd.so 放入
“/usr/bin/”,我接着说下一个需要,就是构建OCA,它与
libdns_sd.so。我为它创建了另一个层并复制到我的源文件中
文件夹名为“Src”,到我层的文件文件夹下的 oca-1.2.7 文件夹。
我为它写了以下食谱。 CAP_HOME 环境变量必须是
设置为基本文件夹 oca-1.2.7,以便“makefileOCA”等工作。
将带下划线的文本放在引号中似乎有助于让 StackOverflow 接受我的问题格式。
我还把 // 注释标记放在我的代码或输出块中的每一行前面。不确定这是否有帮助。
//DESCRIPTION = "OCA"
//PRIORITY = "optional"
//SECTION = "protocols"
//LICENSE = "MIT"
//LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
//SRC_URI = "file://oca-1.2.7"
//S = "${workdir}/oca-1.2.7/Src"
//# Need to override S because BitBake expects the source to be in a dir called
//# oca-1.2.7 in the work dir,but it's actually additionally under Src/.
//# Need a do_compile,since OCA has a makefile with a non-standard name,//# makefileOCA. Also needs non-standard flags,-f and linuxRelease.
//do_compile() {
//export CAP_HOME="${workdir}/oca-1.2.7"
//make -f makefileOCA linuxRelease
//}
//do_install() {
// install -d ${D}${libdir}
// cp ../Obj/linuxApp/Release/OcaProtoController.so ${D}${libdir}/OcaProtoController.so
// chmod 0755 ${D}${libdir}/OcaProtoController.so
//}
然后我“bitbaked”或编译我的新层:

//./tmp/work/aarch64-poky-linux/oca/1.2.7-r0/package/usr/lib/OcaProtoController.so
这非常令人鼓舞。我得到了我的构建结果, OcaProtoController.so,现在我只需要通过指定的条带 和“objcopy”操作,或“do_populate_sysroot”和“do_package”,它们似乎 是各自的任务。
那么我该如何解决这个问题?此外,您能否向我指出最相关的 文档以便我可以理解基本流程?同时我 继续谷歌和阅读。
编辑:我有点希望得到一个可以避免以下可怕黑客攻击的答案。但不管怎样,我想。
我发现并尝试了这个:https://github.com/nefethael/meta-random/issues/1 :
//It compiles if you do the most horrible hack ever.
//INHIBIT_SYSROOT_STRIP = "1"
//INHIBIT_PACKAGE_STRIP = "1"
//INHIBIT_PACKAGE_DEBUG_SPLIT = "1"
//The file stats is an executable file hidden in the vendor reference.
我将这三行放在 ~/Yocto/imx-yocto-bsp/build-wayland/conf/local.conf 下的 CONF_VERSION = "1" 下。这显然产生了影响:
它似乎遍历了几乎所有其他包裹,大约需要 20 分钟:

似乎不打包构建结果不是答案。
编辑:一个明显的蠕虫罐头已经打开,需要一个新问题;请参阅How do I get a complex non-Yocto makefile-based project to cross-compile in a Yocto layer?
解决方法
你问题的最后一个错误告诉你 do_install 任务安装文件,但它们没有分配给任何包。 将以下几行添加到您的食谱中
FILES_${PN} += "${libdir}/OcaProtoController.so"
