Question

I have been staring and googling this but I cannot see what I have done.

I have a working project on a 32 bit machine. I have just pulled the repository to a 64 bit machine (which was the original development machine for the project) and I am now getting the following linking errors when trying to build the testing binary

/usr/bin/ld: error: /usr/lib/libboost_test_exec_monitor-mt.a(unit_test_log.o): requires dynamic R_X86_64_PC32 reloc against 'std::basic_string<char, std::char_traits<char>, std::allocator<char> >::_Rep::_S_create(unsigned long, unsigned long, std::allocator<char> const&)' which may overflow at runtime; recompile with -fPIC
/usr/bin/ld: error: /usr/lib/libboost_test_exec_monitor-mt.a(unit_test_log.o): requires unsupported dynamic reloc 11; recompile with -fPIC

I really can’t see what I could have changed. The boost libraries are pulled straight from the ubuntu repositories. Anyone with any clues.

Answer 1

Okay, Simon’s answer really helped me along the way.

The ultimate solution to this particular problem was to use

libboost_unit_test_framework

(which comes with a shared library) in place of

libboost_test_exec_monitor

(which does not)
