使mongo-cxx驱动程序找不到包含

Question

我一直在尝试为OSX10.10上的C++11编译mongo-cxx-driver，但我遇到了一些问题。libbson和mongo-c-driver都已成功构建和安装，库分别安装到/usr/local/lib，头文件分别安装到/usr/local/include/libbson-1.0和/usr/local/include/libmongoc-1.0。我成功地从mongo-cxx-driver/build目录运行了cmake，这是shell的完整输出：

~/code/cpp/mongo-cxx-driver/build  ((r3.0.1)) $> cmake -DLIBBSON_DIR=/usr/local/include/libbson-1.0 -DLIBMONGOC_DIR=/usr/local/include/libmongoc-1.0 -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..

-- Build files have been written to: /Users/user/code/cpp/mongo-cxx-driver

当我从mongo-cxx-driver目录运行make时，我得到以下错误：

...
[  4%] Building CXX object src/bsoncxx/CMakeFiles/bsoncxx.dir/array/view.cpp.o
/Users/user/code/cpp/mongo-cxx-driver/src/bsoncxx/array/view.cpp:21:10: fatal error: 'bson.h' file not
  found
#include <bson.h>
         ^
1 error generated.

显然，编译器找不到这些包含...但是为什么呢？这不就是在cmake命令行中设置LIBBSON_DIR和LIBMONGOC_DIR的目的吗？

编辑:我使用cmake；make；sudo make install从它们的git源代码构建了C驱动程序和libbson。今天，我从头开始编写mongo-cxx-driver，记录整个过程中的所有问题。cmake in mongo-cxx-driver/build生成以下输出：

(如果需要其他线路，我很乐意发送它们)。ls /usr/local/lib/pkgconfig显示如下：

lcms2.pc        libbson-1.0.pc      libmongoc-1.0.pc    libmongoc-ssl-1.0.pc    libtiff-4.pc        mysqlclient.pc

Answer 1

找到了问题所在。@acm请求显示pkg-config --cflags --libs libmongoc-1.0 libbson-1.0的输出，我尝试这样做：

~/code/cpp/mongo-cxx-driver/build  (master) $> pkg-config --cflags --libs libmongoc-1.0 libbson-1.0
-bash: pkg-config: command not found

显然没有安装pkg-config。通过homebrew进行快速安装之后，我运行相同的代码行，得到：

~/code/cpp/mongo-cxx-driver/build  (master) $> pkg-config --cflags --libs libmongoc-1.0 libbson-1.0
-I/usr/local/include/libmongoc-1.0 -I/usr/local/include/libbson-1.0 -L/usr/local/lib -lmongoc-1.0 -lbson-1.0

在那之后，cmake运行得很好，make也是如此。

感谢您的帮助:-)
