c++ - 如何为开源 uEye 应用程序正确安装缺少的库

Question

我需要构建 iDS 的 SimpleStreamer 应用程序

我有以下结构的存档：

这是 SimpleStreamer 的内容CMakeLists.txt：

project(SimpleStream)
cmake_minimum_required(VERSION 2.8)
aux_source_directory(. SRC_LIST)

add_executable(${PROJECT_NAME} ${SRC_LIST})
target_link_libraries(${PROJECT_NAME} ueye_api ueye_stream)

lib我将项目的 common和文件夹复制include到系统范围lib和include：

sudo cp include/ueye_stream.h /usr/local/include/
sudo cp lib/libueye_stream.so.2.0 /usr/local/lib/

/usr/local/lib我以与项目相同的方式制作符号链接lib：

lrwxrwxrwx 1 olga olga     19 июн 21  2016 libueye_stream.so -> libueye_stream.so.2
lrwxrwxrwx 1 olga olga     21 июн 21  2016 libueye_stream.so.2 -> libueye_stream.so.2.0
-rwxr-xr-x 1 olga olga 151018 июн 21  2016 libueye_stream.so.2.0

我sudo ldconfig没有任何错误。

我是cmake ..从 SimpleStreamer 的build目录中做的：

-- Configuring done
-- Generating done
-- Build files have been written to: /home/olga/camera/ueye/ueye_stream/ueye_stream_x64/src/SimpleStreamer/build

但是当我继续make阶段时，我得到了很多错误：

Answer 1

OK，看了一些理论资料和《演绎思维》（c），我找到了解决办法：

1. 我创建了文件夹/usr/local/lib/ueye_olga
2. 我将所有必要的库从项目的根目录lib及其子文件夹复制到ueye_olga，请参见下面的输出。
3. 我删除了不必要的文件，并用链接替换了它们（见下面的解释）
4. 我创建了/etc/ld.so.conf.d/ueye_olga.conf with path to the/usr/local/lib/ueye_olga`，见下文。
5. 我做了sudo ldconfig
6. 我检查了libueye_stream.so是否正确链接（见下文）
7. 我需要移动libueye_stream.so它的链接文件夹，我不知道为什么，请参阅下面的错误。
8. 再次sudo ldconfig
9. make正常工作

删除不必要的文件：

如果你不创建软链接，你会得到如下错误：

/sbin/ldconfig.real: /usr/local/lib/ueye_olga/libavcodec.so.56 不是符号链接

原因：

与库模块一样，libstdc 可以作为多个版本之一安装。通常只安装一个版本，而其他可能的版本表示为已安装版本的符号链接。符号链接是指向已安装模块的另一个名称。例如，我安装了 /usr/lib/libstdc++.so.6.0.10。我还有 /usr/liblibstdc++.so.6 作为指向 /usr/lib/libstdc++.so.6.0.10 的符号链接，因此您可以使用任一名称访问 libstdc++。

取自这里。

/etc/ld.so.conf.d/ueye_olga.conf：

olga@olga-MS-7758:/usr/local/lib$ cat /etc/ld.so.conf.d/ueye_olga.conf
/usr/local/lib/ueye_olga

正确链接 ueye_stream：

不是，将libueye_stream.so软链接移至/usr/local/lib.
