我用C ++创建了一个ROS2 rviz插件,我需要使用cmake将其编译为共享库(.so
)。我已经有一个正常工作的CMakeLists.txt(请参见下文),它创建了一个 static 库(.a
);不过,我需要将其共享。
但是,当我将SHARED
关键字添加到add_library
宏时(在下面的代码中进行了注释),它引发了这个奇怪的错误:
/usr/bin/ld: cannot find -lXAW_LIBRARY-NOTFOUND
现在,我在SO上查看了很多“ / usr / bin / ld:找不到 [某些库] ”问题(例如this),但是我的错误似乎更加奇怪,因为它似乎在错误中包含错误(“ -lXAW_LIBRARY-NOTFOUND
”)(/ usr / bin / ld:找不到...)。我的意思是,他为什么还要寻找一个名为LIBRARY_NOTFOUND的库?
我在使用cmake 3.10的Ubuntu xenial 16.04。

请注意:此问题与ROS有关;我不是cmake向导,所以可能我在cmake中做的是一个非常错误的事情……我已经在answers.ros
上问过a more broad version of this question,但是它似乎太特定于cmake了。无论如何,我在那里没有得到答案。 (抱歉,上面的代码不是MWE,我可以根据需要创建一个,但是需要ROS2进行编译...)
答案 0 :(得分:1)
通常,如果您将某些库名用作target_link_libraries
函数的参数,则会弹出该错误。
要么
我会把target_link_libraries(delegator_lib rviz_common::rviz_common)
和link_directories(${ament_cmake_LIBRARY_DIRS})
看成是犯罪嫌疑人。
在 CMake 中,您可以使用MESSAGE
命令进行各种调试,在其中可以显示CMake变量的值,以检查它们对系统中的内容是否有意义。 / p>
您还可以尝试安装sudo apt-get install libxaw7-dev
这样的 XAW 库。可能是您链接到的库之一依赖于XAW库。
