Question

我按照官方安装教程进行操作：https://mongodb.github.io/mongo-cxx-driver/mongocxx-v3/installation/ 我在make＆amp;＆amp;和make之前启用了标志--enable-static = yes和./configure sudo make install我得到了libmongoc-1.0.a和libbson-1.0.a这些都是静态的。我已经给了

cmake -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_INSTALL_PREFIX=/your/cxxdriver/prefix
    -DLIBMONGOC_DIR=/your/cdriver/prefix
    -DLIBBSON_DIR=/your/cdriver/prefix ..

然后制作＆amp;＆amp; sudo make install也完成了。所以到目前为止，一切都很好。

当我检查链接到我的最终可执行文件的库是

时

ldd ./prabhandhak

这里我想链接mongo静态库

这是我的cmakelist.txt

请帮我链接静态库到cmakefile.txt

Answer 1

在mongocxx的CMakeLists.txt中看起来有相关的选项。所以

--- cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
+++ cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=False -DCMAKE_INSTALL_PREFIX=/usr/local ..

（这是您教程的第4步）
