问题 I have 2 files: library.dll and library.h with some code that I need in my own project. I'm working on Windows with Clion where I should config this with CMake. I tried this way: cmake_minimum_required(VERSION 3.6) project(test2) set(CMAKE_CXX_STANDARD 11) link_directories(C:\\Users\\Johny\\CLionProjects\\test2) set(SOURCE_FILES main.cpp) add_executable(test2 ${SOURCE_FILES}) target_link_libraries(test2 library.dll) It compiled but didnt work. Returns code -1073741515 How can I handle with it

关于gcc、make和CMake的区别

阅读更多关于关于gcc、make和CMake的区别

CMake是一种跨平台编译工具，比make更为高级，使用起来要方便得多。CMake主要是编写CMakeLists.txt文件，然后用cmake命令将CMakeLists.txt文件转化为make所需要的makefile文件，最后用make命令编译源码生成可执行程序或共享库（so(shared object)）.它的作用和qt的qmake是相似的。作者：辉常哥链接：https://www.zhihu.com/question/36609459/answer/89743845 来源：知乎著作权归作者所有。商业转载请联系作者获得授权，非商业转载请注明出处。 1.gcc是GNU Compiler Collection（就是GNU编译器套件），也可以简单认为是编译器，它可以编译很多种编程语言（括C、C++、Objective-C、Fortran、Java等等）。 2.当你的程序只有一个源文件时，直接就可以用gcc命令编译它。 3.但是当你的程序包含很多个源文件时，用gcc命令逐个去编译时，你就很容易混乱而且工作量大 4.所以出现了make工具 make工具可以看成是一个智能的批处理工具，它本身并没有编译和链接的功能，而是用类似于批处理的方式—通过调用makefile文件中用户指定的命令来进行编译和链接的。 5.makefile是什么？简单的说就像一首歌的乐谱，make工具就像指挥家

Cannot compile pcl examples with cmake

阅读更多关于 Cannot compile pcl examples with cmake

问题 I just got the pcl installed and would like to run the examples in the folder /pcl-pcl-1.7.1/examples. The different examples each have CMakeLists.txt in them, so I thought I just do a cmake . in the terminal followed by make to compile it. After doing that in the terminal I got CMake Warning (dev) in CMakeLists.txt: No cmake_minimum_required command is present. A line of code such as cmake_minimum_required(VERSION 2.8) So I looked into the cmake file and the weird thing is that these cmake

How to add files to a non-executable or non-library target with CMake

问题 I understand I can add some files to a target in CMake if the target is an executable or a library with the following command: add_executable(${target_name} ${source_files}) or add_library(${target_name} ${source_files}) Then my question is what if the target is not an an executable or a library. I raise this question because I want to build a target for documentation with Doxygen, and this can be done with the following commands: find_package(Doxygen) if(DOXYGEN_FOUND) set(doxyfile_in $

Caffe: CMake源码编译（OpenCV4.2+CUDA)

阅读更多关于 Caffe: CMake源码编译（OpenCV4.2+CUDA)

周六周日在家倒腾了两天，总算稍微了解点pycaffe的一些接口和api设置了，但是针对不同层，还是有很多注意的细节的，所以也准备写个博客专门总结pycaffe的常见层参数设置，（LZ这个蠢啊，之前居然手写prototxt，一把辛酸泪，太傻了/(ㄒoㄒ)/~~）之前已经写过用Anaconda直接安装caffe，这样安装caffe不香嘛，为啥非得源码再来安装一次呢？ 1.项目里后端是用的tensorflow的接口，前端是要用caffe的接口，caffe的有些参数设置还是源码查询比较方便 2.有一些层是比较特殊的，这种定制化的层可能需要使用c写完之后，再进行源码编译不过源码编译还是有很多坑的，且听LZ一一道来：首先下载源码， https://github.com/weiliu89/caffe 按照tutorial安装依赖项： http://caffe.berkeleyvision.org/installation.html LZ的小小笔记本是Ubuntu16.04 所以需要先安装对应的依赖库 sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev protobuf-compiler sudo apt-get install --no

CMake and Window .Lib Files

问题 I have been struggling to find an answer to this question across Stackoverflow, at least one that I understand. I recently bought CLion and want to port an older project from Visual Studio over to it. But I have no idea how to link or add .lib files to my project. I need to link Xinput and DSound. In Visual Studio I just added the headers and then added these to the top of my file #pragma comment(lib, "XInput.lib") #pragma comment(lib, "Dsound.lib") I just have absolutely no idea how to link

CMake building a static library with other static library

阅读更多关于 CMake building a static library with other static library

问题 My problem is as follows : I have OpenSSL as static libraries ( libcrypto.a and libssl.a ). Compiled on Windows with MSys2/MinGW64 . Besides that, I have a small self written library based on OpenSSL . Now I want to "bundle" the Crypto lib from OpenSSL with My lib to a "big" static library for later statically compiling in other applications on Windows without deploying any library. What would a CMakeLists.txt file looks like? And are the prerequisites ( OpenSSL as static libs ) correct?
