I am trying to compile mongo-cxx-driver-r3.1.1 on Ubuntu14.4 . I have installed mongo-c-driver-1.6.3 from source as per instructions. 

pkg-config --cflags --libs libmongoc-1.0 libbson-1.0 returns 
-I/usr/local/include/libmongoc-1.0 -I/usr/local/include/libbson-1.0  -L/usr/local/lib -lmongoc-1.0 -lsasl2 -lssl -lcrypto -lrt -lbson-1.0

I have boost version 1.57. When I try to compile mongo-cxx-driver-r3.1.1 as per the instructions provided in https://mongodb.github.io/mongo-cxx-driver/mongocxx-v3/installation/ using cmake. 

cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local  ..

I get the following logs :

-- Boost version: 1.57.0

-- Configuring done

-- Generating done

-- Build files have been written to: /user/home/mongo-c-driver-1.6.3/mongo-cxx-driver-r3.1.1/build

I have tried other options such as:

cmake  -DBSONCXX_POLY_USE_MNMLSTC:Bool=OFF -DBSONCXX_POLY_USE_BOOST:Bool=ON -

DCMAKE_VERBOSE_MAKEFILE=ON  -DCMAKE_C_COMPILER="/usr/bin/gcc" -
DCMAKE_CXX_COMPILER="/usr/bin/g++-4.8"  -DCMAKE_BUILD_TYPE=Release -
DCMAKE_INSTALL_PREFIX=/usr/local -DLIBMONGOC_DIR=/usr/local/lib -
DLIBBSON_DIR=/usr/local/lib ..

However, I dont see the mongocxx related libraries or header files. Following is the CMakeFiles/CMakeOutput.log output:

The system is: Linux - 3.13.0-32-generic - x86_64 Compiling the CXX

compiler identification source file "CMakeCXXCompilerId.cpp"

succeeded. Compiler: /usr/bin/g++-4.8 Build flags: Id flags:

The output was:

I could post the entire cmake output if it is meaningful. I grep'ed for "error" or "fail" in the file , but wasn't able to find either strings.

It would be great if someone could point out, what I am missing here?

    This question is *very* hard to read and understand. Are you saying that CMake failed? I don't see any evidence of that, or at least not in a comprehensible format? If CMake succeeded, you need to run "make && make install" after running cmake in order to build and install the driver. – acm Jun 23 '17 at 14:03
  • running cmake you only prepare make script. I.e. you aren't compiling anything when run `cmake ....`. To actually compile something you should run `make` command from where you point cmake to prepare build. – Alexey Jun 23 '17 at 14:11
  • Hi Chitra! If you still haven't solved your issue, feel free to ask a question on the MongoDB users Google Group[1] or the mongocxx JIRA project[2], and I can help you debug it.

  • Sorry for the delay in posting. The issue got resolved. There was some issue with the make. – Chitra Vaidyanathan Jul 18 '17 at 12:01
