[odb-users] Linking problem at Ubuntu 16.04

[Martin Schneider]

Hi Boris,

you are right with your asumption about C++98.
I now rerun:
 > make distclean
 > ./configure --with-database=mysql CXXFLAGS="-std=c++11 -Wno-deprecated"
 > make

But original error comes up again:

make[4]: Verzeichnis 
„/home/martin/projects/odb/odb-tests-2.4.0/common/access“ wird betreten
