g++ -c -Wall -m64 -I/net/simdata/OpenSourceLibs/Boost/rel-1.69.0/ -fpic -O3 SINRCalculation.cpp -o _gnuRelease/SINRCalculation.o

Now that source file uses boost/multi_array.hpp. The above compiler command gives error:

In file included from /usr/include/boost/multi_array.hpp:30:0,
                 from SINRCalculation.cpp:25:
/net/simdata/Hudson_OpenSourceLibs/Boost/rel-1.69.0/boost/type_traits.hpp:118:10: fatal error: boost/type_traits/is_nothrow_swappable.hpp: No such file or directory
 #include <boost/type_traits/is_nothrow_swappable.hpp>
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

Now my copy of boost 1.69 does contain is_nothrow_swappable.hpp so, at first sight, that error is surprising.

I think what is happening is the is_nothrow_swappable.hpp is being searched for on the system library path (boost 1.65 does not have that file), not the one I specified using -I.

Am I correct?  If so, how can I force the compiler to use the boost 1.69 path consistently for all paths?
