Most likely the issue is that your link rules $(CC) $(LFLAGS) $(SNAPMERGE_OBJ) -o ../bin/snapmerge and so on place the libraries ahead of the object files: see for example Why does the order of '-l' option in gcc matter?

Part Number: C6000-CGT It seems that the standard include file math.h has a define for trunc, this gives issues with std::ios::trunc symbol (defined in e.g. ios

4) Type-generic macro: If arg has type long double, truncl is called. Otherwise, if arg has integer type or the type double, trunc is called. Otherwise, truncf is called. If no errors occur, the nearest integer value not greater in magnitude than arg (in other words, arg rounded towards zero), is returned.
