Problems trying to compile MongoCxx

Working with Data Drivers & ODMs
#1

Hi, I’m currently trying to compile mongocxx-driver under Ubuntu, and I ran into some issues.

I use the guide found at
http://mongocxx.org/mongocxx-v3/installation/
and have successfully installed the dependencies as described under
http://mongoc.org/libmongoc/current/installing.html

Under Step 4, Configure the driver, I ran into the issues.
So far, any attempt of calling cmake resulted in this:

<<
CMake Error at src/bsoncxx/CMakeLists.txt:81 (find_package):
By not providing “Findlibbson-1.0.cmake” in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
“libbson-1.0”, but CMake did not find one.

Could not find a package configuration file provided by “libbson-1.0”
(requested version 1.13.0) with any of the following names:

libbson-1.0Config.cmake
libbson-1.0-config.cmake

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

Those files do not exist. I have libbson-1.0, but not any libbson cmake file.

So far, I found the similar questions



but those did not really help me. I feel that if I blindly start to edit some CMakeFile, this will do me no good.

If it is relevant, my last attempt at configuration used the command
cmake …
-DCMAKE_BUILD_TYPE=Release
-DBSONCXX_POLY_USE_MNMLSTC=1
-DCMAKE_INSTALL_PREFIX=/usr/local

I tried out several variants and also to execute it under sudo, same outcome.
I also tried to set CMAKE_PREFIX_PATH to something that contains the libbson library files, but as it specifically asks for a libbson cmake file, I didn’t expect it to work to begin with.

@Ksortakh_Kraxthar how did you install the C driver? Was it from source or from Ubuntu repository packages? What commands did you use?

@Robert_Sanchez
You were correct, the C driver wasn’t properly built, and it works now.
Thanks, I would never have guessed that a dependency was missing from the error message.

@Ksortakh_Kraxthar That’s excellent news. Feel free to let us know if you encounter any other issues. Incidentally, depending on what version of Ubuntu you are using, you may find that a recent C driver is available directly via apt.

I’m experiencing the same problem, but installing the C driver didn’t seem to resolve it:

$ sudo apt-get install libmongoc-1.0-0

$ cmake ...    
-DCMAKE_BUILD_TYPE=Release  
-DCMAKE_PREFIX_PATH=/opt/mongo-c-driver  
-DCMAKE_INSTALL_PREFIX=/opt/mongo-cxx-driver

@Willow_Willis it is not clear what you are trying to do. The command sudo apt-get install libmongoc-1.0-0 installs the runtime library, not the development library and headers. You probably need sudo apt-get install libmongoc-dev instead.

Additionally, the packages will install everything under /usr, so passing -DCMAKE_PREFIX_PATH=/opt/mongo-c-driver is probably not what you want. If you already have a C Driver built and installed there, it is possible that it will be used instead of the C Driver from distro packages.

@Willow_Willis Not sure if it helps, but the full set of commands I used was:

sudo apt-get install libmongoc-1.0-0
sudo apt-get install libbson-1.0
sudo apt-get install cmake libssl-dev libsasl2-dev

wget https://github.com/mongodb/mongo-c-driver/releases/download/1.16.2/mongo-c-driver-1.16.2.tar.gz
tar xzf mongo-c-driver-1.16.2.tar.gz
cd mongo-c-driver-1.16.2
mkdir cmake-build
cd cmake-build
cmake -DENABLE_AUTOMATIC_INIT_AND_CLEANUP=OFF ..
sudo make install

git clone https://github.com/mongodb/mongo-cxx-driver.git \
    --branch releases/stable --depth 1
cd mongo-cxx-driver/build

sudo cmake ..                                \
    -DCMAKE_BUILD_TYPE=Release          \
    -DBSONCXX_POLY_USE_MNMLSTC=1                      \
    -DCMAKE_INSTALL_PREFIX=/usr/local

sudo make EP_mnmlstc_core
sudo make
sudo make install

Especially note the second block, which I originally left out until @Robert_Sanchez pointed me at the C driver.
Might be that some parts are redundant, but worked for me.

If you are building the C driver from source, it is better to not have libmongoc-1.0-0 and libbson-1.0 installed via apt. If your distro has a new enough C Driver package, then a simple sudo apt-get install libmongoc-dev is all you need to have the C Driver available to you.

I removed the runtime library and headers, then tried installing the development library from apt. Looks like my distro doesn’t have a new enough C Driver:

$ sudo apt-get install libmongoc-dev
$ sudo cmake ..                                    
-DCMAKE_BUILD_TYPE=Release              
-DBSONCXX_POLY_USE_MNMLSTC=1                         
-DCMAKE_INSTALL_PREFIX=/usr/local

bsoncxx version: 3.5.0
CMake Error at src/bsoncxx/CMakeLists.txt:98 (find_package):
  Could not find a configuration file for package "libbson-1.0" that is
  compatible with requested version "1.13.0".

  The following configuration files were considered but not accepted:

    /usr/lib/x86_64-linux-gnu/cmake/libbson-1.0/libbson-1.0-config.cmake, version: 1.9.2

So I removed the development library and followed @Ksortakh_Kraxthar’s instructions for installing the mongo-c-driver from source (without installing the client libraries again). I did need to install zlib ( sudo apt-get install zlib1g-dev ) before it would make install, however.

THEN I was finally able to make MongoCxx!

Thanks to both of you for your help.

@Willow_Willis then I suspect you are running Debian stretch, or Ubuntu Bionic. Both of those would have rather old C driver versions, which would not be sufficient for building the latest C++ driver. I’m glad you were able to sort it out. If you are interested in building packages that you can install with apt, then this post may interest you: C and C++ Driver for Debian & Ubuntu users
