# -qroconst make the strings readonly, which is usually the default.
#           This helps in the data library,
# -qproto assumes all functions are prototyped (for optimization)

## Commands to link
## We need to use the C++ linker, even when linking C programs, since
##  our libraries contain C++ code (C++ static init not called)
LINK.c=		$(CXX) $(CXXFLAGS) $(LDFLAGS)

## Commands to make a shared library
## -G means -berok -brtl -bnortllib -bnosymbolic -bnoautoexp
## -bh:8 means halt on errors or worse.  We don't display warnings about
##      duplicate inline symbols.
SHLIB.c=	$(CXX) -qmkshrobj -G $(LDFLAGS)
