大家好我的静态图书馆链接有问题。我在ubuntu 12.0.4中执行c ++应用程序，我必须为ARM创建此.cpp文件的执行。该文件包含opencv库。
所以我做的第一件事就是从git仓库下载opencv源代码：
git clone https://github.com/Itseez/opencv.git
完成后没有问题，我创建了一个新目录并执行了Cmake：
cmake -DSOFTFP = ON -DBUILD_SHARED_LIBS = 0 -DCMAKE_TOOLCHAIN_FILE = .. / opencv / platforms / linux / arm-gnueabi.toolchain.cmake ../ opencv
然后我执行make，并开始为ARM构建静态opencv库。一切都很好，我可以看到刚刚创建的静态库。
所以我尝试像这样编译：
arm-linux-g ++ -static -o camera IpCamPthread.cpp -I / usr / local / include -L / home / jesus / opencv / build / lib -lopencv_core -lopencv_imgproc -lopencv_highgui
然后出现此错误：

我正在寻找一些我无法得到任何东西的东西。 有人可以帮忙吗？ 非常感谢 即使我正在调查，我发现为了确保包含所有依赖项，我应该使用pkgconfig进行编译，如下所示：
arm-linux-g++ -o example IpCamPthread.cpp `pkg-config --static --cflags --libs opencv`
并且它创建了一个可执行文件，但当我制作＆＃34; file＆＃34;在可执行文件上这是结果： 示例：ELF 32位LSB可执行文件，ARM，版本1（SYSV），动态链接（使用共享库），用于GNU / Linux 2.6.26，未剥离 那么是一个ARM文件，但它是动态链接的，然后它在我的ARM中不起作用，我不明白为什么在我的＆＃34; opencv.pc＆＃34;中进行动态链接。文件有这个：

所有使用open.pc的库都是静态的，所以我不知道为什么要编译和构建一个dinamic可执行文件。
有人??
答案 0 :(得分：1)
向链接器遗漏一些-lSomeLib语句的经典案例。 似乎缺少pthread和gzip等等。要手动查找所需的库，请在“lib”文件夹中输入符号名称。
答案 1 :(得分：1)
大家好，感谢Idinev我一直在寻找如何添加库，以及如何确保我需要的每个库都是属性链接的。
所以我尝试使用pkgconfig我上面怎么说，但是我无法获得静态可执行文件，最后这是因为sintaxis错误。我用这个：
arm-linux-g ++ -static -o example IPCamera.cpp pkg-config --cflags --libs opencv
它有效，它创建了一个可执行文件，当我执行＆＃34;文件可执行文件＆＃34;输出是：
示例：ELF 32位LSB可执行文件，ARM，版本1（SYSV），静态链接，用于GNU / Linux 2.6.26，未剥离
静态链接！
