【问题描述】：
我需要弄清楚如何基于 CMake 创建一个非常简单的共享库来管理包的配方。 目标是以原子方式将 .so 库提供到 Yocto 构建系统中，以便其他管理应用程序级别的配方使用。
这是简单的cpp代码
#include <iostream>
#include "Student.h"
using namespace std;
Student::Student(string name):name(name){}
void Student::display(){
cout << "A student with name " << this->name << endl;
}
这是一种 CMakeList.txt
cmake_minimum_required(VERSION 2.8.9)
project(directory_test)
set(CMAKE_BUILD_TYPE Release)
#Bring the headers, such as Student.h into the project
include_directories(include)
#However, the file(GLOB...) allows for wildcard additions:
file(GLOB SOURCES "*.cpp")
#Generate the shared library from the sources
add_library(testStudent SHARED ${SOURCES})
#Set the location for library installation
install(TARGETS testStudent DESTINATION lib)
install(FILES student.h DESTINATION include)
这是studentlib_0.1.bb的食谱
SUMMARY = "Cmake application - creates a library"
SECTION = "examples"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
SRC_URI = "\
file://CMakeLists.txt \
file://student.cpp \
file://student.h \
"
S = "${WORKDIR}"
inherit cmake
EXTRA_OECMAKE = ""
问题是当我构建特定的配方studentlib时
$ bitbake studentlib
...
Build Configuration:
BB_VERSION = "1.38.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "universal"
TARGET_SYS = "arm-poky-linux-gnueabi"
MACHINE = "qemuarm"
DISTRO = "poky"
DISTRO_VERSION = "2.5.2"
TUNE_FEATURES = "arm armv5 thumb dsp"
TARGET_FPU = "soft"
...
NOTE: Executing RunQueue Tasks

ERROR: Task (/home/me/yocto-qemuarm-sumo/poky/meta-me/recipes-cmake/studentlib/studentlib_0.1.bb:do_package_qa) failed with exit code '1'
我该如何解决这个问题？ 我找不到任何解释的例子。
谢谢
