如何在 Yocto bitbake 编译步骤中剥离和 objcopy 构建的 .so 文件? [英] How do I strip and objcopy a built .so file in the Yocto bitbake compile step?
问题描述
这个问题来自:
这将通过几个帖子追溯到相当大的背景.
This question follows on from:
Do I need to edit the .patch files needed for building mdns 878.200.35 in Yocto?
This chains back through several posts to considerable background.
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将名为Src"的文件夹复制到我图层中 files 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.
Since "mDNS" seemed to be working in my target and the recipe puts libdns_sd.so in
"/usr/bin/", I went on to the next need, which is to build OCA, which links with
libdns_sd.so. I created another layer for it and copied in my source files, in a
folder called "Src", to an oca-1.2.7 folder under the files folder in my layer.
I wrote the following recipe for it. The CAP_HOME environment variable has to be
set to the base folder, oca-1.2.7, for "makefileOCA", etc., to work.
Putting underlined text in quotes seems to help get StackOverflow to accept my question formatting.
Also I put // comment markers in front of every line in my code or output blocks. Not sure if that helped.
//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:
Then I "bitbaked" or compiled my new layer:

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对象副本"操作，或do_populate_sysroot"和do_package"，它们似乎是各自的任务.
This is extremely encouraging. I am getting my build result, OcaProtoController.so, and now I just need to get it through the indicated strip and "objcopy" operations, or "do_populate_sysroot" and "do_package", which appear to be the respective tasks.
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.
So how do I fix this? Additionally, can you point me to the best relevant documentation so that I can understand the fundamental processes? Meanwhile I continue to google and read.
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.
I'm kind of hoping for an answer that would obviate the following horrible hack. But whatever works, I guess.
我发现并尝试了这个:https://github.com/nefethael/meta-随机/问题/1 :
I found and tried this: 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 CONF_VERSION = 1".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:
I put those three lines in ~/Yocto/imx-yocto-bsp/build-wayland/conf/local.conf under CONF_VERSION = "1". That clearly had an effect:
It seemed to go over almost every other package, taking about 20 mins:

似乎不打包构建结果不是答案.
It seems that not packaging the build result is not the answer.
一个明显的蠕虫罐头已经打开，需要一个新问题；请参阅 如何让一个复杂的非 Yocto 基于 makefile 的项目在 Yocto 层中交叉编译?
An apparent can of worms has opened, necessitating a new question; please see How do I get a complex non-Yocto makefile-based project to cross-compile in a Yocto layer?
推荐答案
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
The last error of you question tells you that the do_install tasks installs files but they are not assigned to any package. Add following lines to your recipe
FILES_${PN} += "${libdir}/OcaProtoController.so"
