使用cmake的Yocto食谱找不到git

Question

我正在尝试建立一个蒙哥-CXX-驱动程序(https://github.com/mongodb/mongo-cxx-driver)的配方。我有libbson和mongo-c驱动程序的工作方法，这是要求，但是当我尝试构建mongo-cxx-驱动程序时，当我试图克隆git回购时，它失败了。

$ bitbake mongo-cxx-driver

| CMake Error at 
/home/hme/projects/platform/yocto/poky/build/tmp/work/core2-64-poky-linux/mongo-cxx-driver/3.1.3-r0/recipe-sysroot-native/usr/share/cmake-3.8/Modules/ExternalProject.cmake:1805 (message):

食谱：

DESCRIPTION = "MongoDB C++ driver"
SECTION = "libs"
HOMEPAGE = "https://github.com/mongodb/mongo-cxx-driver"
LICENSE = "Apache-2.0"
DEPENDS = "libbson mongo-c-driver git-native"

inherit cmake pkgconfig

SRC_URI = "https://github.com/mongodb/mongo-cxx-driver/archive/r${PV}.tar.gz"

SRC_URI[md5sum] = "fd1ff0f9b2122225e3b402c2bae30427"
SRC_URI[sha256sum] = "cb1b371eb34e991b8bfac65146f862cd379aa8f7270c430e5f3d71d843245ed9"

LIC_FILES_CHKSUM = "file://LICENSE;md5=d2794c0df5b907fdace235a619d80314"

S = "${WORKDIR}/mongo-cxx-driver-r${PV}"

如果我跑：

$ bitbake -c devshell mongo-cxx-driver

通过devshell手动构建，它工作得很好。

有什么可能是错的吗？

Answer 1

你应该尝试添加：

OECMAKE_FIND_ROOT_PATH_MODE_PROGRAM = "BOTH"

在继承cmake后返回到菜谱中。

Answer 2

包git-本机可能在提供变量中列出。如果是这样的话，您必须将git-replacement-native作为依赖项添加到菜谱中。
