如何在 yocto 中使用配方交叉编译 Qt 项目

Question

我正在尝试从配方交叉编译一个 qt 项目。我已经创建了一个食谱文件，但是当我尝试对其进行 bitbake 时。我遇到了错误

这是我的食谱文件

DESCRIPITION = "my_project File Transfer"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI = "git://git@bitbucket.org/johndoe/my_ui.git;protocol=ssh;rev=master"

S = "${WORKDIR}/git/my_project"

RDEPENDS_${PN} ="bash"
inherit qmake5
require recipes-qt/qt5/qt5.inc

do_install_append() {
    ## Creating Folder Structure
    install -d ${D}/opt/my_project/bin
    install -d ${D}/home/root/my_project
    install -d ${D}/home/root/my_project/font
    install -d ${D}/home/root/my_project/Images
    install -d ${D}/home/root/my_project/Qml
    ###compile the project  
    oe_runmake INSTALL_ROOT=${D} install

    install -m 0755 ${S}/font/* ${D}/home/root/my_project/font/
    install -m 0755 ${S}/Images/* ${D}/home/root/my_project/Images/
    install -m 0755 ${S}/Qml/* ${D}/home/root/my_project/Qml/
}


FILES_${PN} = "/home/root/my_project"

我看到的错误是

我知道是为了交叉编译。我必须从我的交叉编译工具链位置运行qmake，然后在其上运行make 命令。

我猜这就是我的食谱中缺少的东西。所以我的问题是，我是否将其添加到我的do_configure 如果是这样的话，任何人都可以帮助我或指出我如何填充我的 do_configure 是不是和source/opt/poky/2.7.1/environment一样简单---- 然后qmake

我在这一步画一个空白

请告诉我我做错了什么

Edit1：从配方中删除 inherit allarch

Answer 1

我会留下inherit qmake5 并输入DEPENDS + = "qtbase qtxyz ..."，qtxyz 将是其他依赖模块的列表。
