CppDB compilation errors - c++

Question

I followed the following steps in order to build CppDB:
svn co http://cppcms.svn.sourceforge.net/svnroot/cppcms/cppdb/trunk cppdb-trunk
cd cppdb-trunk
cmake ~/Desktop/cppdb-trunk
make
make install
Afterwards, I'm trying to compile and run the file example1.cpp from the examples directory.
When I run gcc example1.cpp I get the following errors:
/tmp/ccGWenrv.o: In function main':
example1.cpp:(.text+0x2a): undefined reference tostd::allocator::allocator()'

example1.cpp:(.text+0x1fd): undefined reference to `cppdb::statement::operator=(cppdb::statement const&)'
etc.
Any suggestions?

Try g++ example1.cpp -lcppdb. You need to link against the C++ run-time library (using g++ instead of gcc takes care of that) and against CppDB itself (the -lcppdb part). If GCC cannot find the -lcppdb library, you'll have to provide the path using -L, and you may have to use LD_LIBRARY_PATH at run time as well.
