I have same errors, have you solved the problem

I don't think you need Mongo. I was able to successfully build it from source (not using the ./build.sh ubuntu command)

The error is not about Mongo, but about missing dependencies in the 'libraries' folder.

This is because you don't have the submodules (forgot '--recursive' when doing 'git clone' ?)

Checkout the submodules using:

git submodule update --init --recursive

This will pull in the additional git submodules.

Then you can run ./build.sh

Just use following steps:

wget https://github.com/mongodb/mongo-c-driver/releases/download/1.8.0/mongo-c-driver-1.8.0.tar.gz
tar xzf mongo-c-driver-1.8.0.tar.gz
cd mongo-c-driver-1.8.0
./configure --disable-automatic-init-and-cleanup --enable-static
make
sudo make install

git clone https://github.com/mongodb/mongo-cxx-driver.git --branch releases/stable --depth 1
cd mongo-cxx-driver/build
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..
sudo make EP_mnmlstc_core
make
sudo make install

sudo apt-get install mongodb

@gaolitao there is one line missing at the beginning.
sudo apt-get install pkg-config libssl-dev libsasl2-dev

The Instruction is inside source code.

@gaolitao I'm getting this error when running cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..

CMake Error at src/bsoncxx/CMakeLists.txt:81 (find_package):
Could not find a configuration file for package "libbson-1.0" that is
compatible with requested version "1.9.2".

The following configuration files were considered but not accepted:

Do you have any suggestions?

@Babaloncryptolog
I have same errors, i had solved the problem, you should install mongo-c-driver-1.9.2 because it is mongo-cxx-driver-1.9.2 ,download link https://github.com/mongodb/mongo-c-driver/releases

@icodezjb Is the mongo-c-driver-1.9.3 driver too new?

@remcoros Solved. thx. 👍

Commented out every exit statement related to mongo in /path/to/eos/scripts/eosio_build_ubuntu.sh and it worked

old build issue.

@heifner Having this issue now, fresh clone from master, on a fresh Ubuntu aws image. What do you mean old build issue?

I have this error at this time..

  How can I fix these errors?

@gaolitao I encountered the same issue, according the part one of your idea, I solved it. Thanks a lot!
