Answer 1

You are clearly missing some libaries. Run
./autogen.sh
./configure --with-gui=no --disable-wallet
and check the logs (which will tell you which libaries are missing)
Edit: I suggest to remove --with-gui=no --disable-wallet if you want to know full compability.

Answer 2

I also ran into problems compiling bitcoin, as it has a lot of dependencies but it turns out it has a depends system built in to tackle that issue. It's best to utilize it when compiling. So, from scratch:
clone the bitcoin repo and build the depends system:
git clone https://github.com/bitcoin/bitcoin.git
cd bitcoin/depends
make
Once this completes successfully, you'll see a new folder in the depends directory with the name corresponding to your environment, e.g. x86_64-pc-linux-gnu. Set the path to this folder when running ./configure from the repository's root folder using the --prefix flag and run make:
cd ..
./autogen.sh
./configure --prefix=`pwd`/depends/x86_64-pc-linux-gnu
make
