do_rootfs 在 yocto 构建上失败

Question

我已将基于 makefile 的项目集成到 yocto 中的自定义配方中，但出现了一个问题：do_rootfs 失败。

请找到库源，我尝试将此库集成到 oe-core：http://libiec61850.com/libiec61850/wp-content/uploads/2016/02/libiec61850-0.9.0.2.tgz

.bb 文件：

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:" FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

DESCRIPTION = "simple Hello World program" PR = "r0" LICENSE = "CLOSED"

EXTRA_OEMAKE = "'CC=${CC}' 'RANLIB=${RANLIB}' 'AR=${AR}' 'CFLAGS=${CFLAGS} -I${S}/include -DWITHOUT_XATTR' 'BUILDDIR=${S}'"

do_compile() {
             oe_runmake ${S}/make } do_install () {
        oe_runmake install DESTDIR=${D} SBINDIR=${sbindir} MANDIR=${mandir} \
                           INCLUDEDIR=${includedir}
        install -d ${D}${includedir}/libiec61850/
        install -d ${D}${localedir}
        for f in ${S}/.install/include/*.h; do
                install -m 0644 $f ${D}${includedir}/libiec61850/
        done
        install -m 0644 ${S}/.install/lib/* ${D}${localedir}/ }

错误看起来像：

Answer 1

这里很难提供准确的答案，因为有些事情可能是错误的，或者至少是有问题的。所以让我们向后工作：

Collected errors: * opkg_install_cmd: Cannot install package libiec61850.

这意味着在安装软件包列表时找不到文字 libiec61850 文件。我假设您创建了 libiec61850_0.9.0.2.bb，这就是上面的 bb 文件内容所代表的内容。除了我认为是由于复制/粘贴到此处的空白问题之外，它看起来还可以。但是请查看 log.do_compile 和 log.do_install 为了更容易查看构建该软件包是否有任何问题，请执行以下操作：

bitbake -c cleansstate libiec61850
bitbake libiec61850

看看它是否抱怨空包。

接下来，您可能遇到了配方名称的问题 -> 二进制输出重命名。做：

ls tmp/deploy/ipk/*/*iec61850*

看看结果如何。如果您想检查特定 ipk 文件的内容，它们只是“ar”档案，因此您可以提取它们：

mkdir temp
cd temp
ar -x ../foo.ipk
tar zxf data.tar.gz

我已经找到了上述问题的解决方案：
