Question

我已使用以下命令在ubuntu 16.04上安装了Mongo C驱动程序：

sudo apt-get install libmongoc-1.0-0

当我尝试使用cmake进行编译时，出现以下错误：

rolf@ubuntu2:~/src/test$ cmake .

-- The CXX compiler identification is GNU 5.4.0
-- Check for working C compiler: /usr/bin/cc

CMake Error at CMakeLists.txt:4 (find_package):
By not providing "Findlibmongoc-1.0.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"libmongoc-1.0", but CMake did not find one.
Could not find a package configuration file provided by "libmongoc-1.0"
(requested version 1.7) with any of the following names:

    libmongoc-1.0Config.cmake
    libmongoc-1.0-config.cmake

Add the installation prefix of "libmongoc-1.0" to CMAKE_PREFIX_PATH or set
"libmongoc-1.0_DIR" to a directory containing one of the above files.  If
"libmongoc-1.0" provides a separate development package or SDK, be sure it
has been installed.

rolf@ubuntu2:~/src/test$ apt list --installed

在我看来C驱动程序安装有问题，或者可能是cmake？我使用的cmake文件是：

cmake_minimum_required(VERSION 6.5)

# Specify the minimum version you require.
find_package (libmongoc-1.0 1.7 REQUIRED)

message ("--   mongoc found version \"${MONGOC_VERSION}\"")
message ("--   mongoc include path \"${MONGOC_INCLUDE_DIRS}\"")
message ("--   mongoc libraries \"${MONGOC_LIBRARIES}\"")

# sample program

add_executable (error-example error-example.c)
target_include_directories (error-example PRIVATE "${MONGOC_INCLUDE_DIRS}")
target_link_libraries (error-example PRIVATE "${MONGOC_LIBRARIES}")
target_compile_definitions (error-example PRIVATE "${MONGOC_DEFINITIONS}")

我忘了一些步骤吗？欢迎提出想法。

更新
我在另一篇文章中找到了对pkg-config和libmongoc-1.0.pc文件的引用，并进行了检查：

rolf@lme-u1604:~$ pkg-config --cflags --libs libmongoc-1.0
Package libmongoc-1.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libmongoc-1.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libmongoc-1.0' found
rolf@lme-u1604:~$

我检查了整个FS，并且.pc文件不存在。如果确实是问题所在，那么应该使用什么流程创建此问题，以及如何解决此问题？

至少对于ubuntu，操作方法安装尚未完成。

您需要进一步安装：

  sudo  apt-get install libmongoc-dev
  sudo  apt-get install libbson-dev
  sudo  apt-get install libbson-1.0-0

到目前为止很好。

如果您按照他们给的例子

尝试

      #include <mongoc.h>

代替：

      #include <mongoc/mongoc.h>

＃

您的cmake应该如下所示

 cmake_minimum_required(VERSION 3.13)
 project(mongodb_c C)
 set(CMAKE_C_STANDARD 11)
 include_directories("/usr/include/libmongoc-1.0")
 include_directories("/usr/include/libbson-1.0")
 add_executable(mongodb_c main.c)
 target_link_libraries(mongodb_c /usr/lib/x86_64-linux-gnu/libmongoc-1.0.so.0 /usr/lib/x86_64-linux-gnu/libbson-1.0.so.0)

假设您将代码放在名为main.c的文件中
