## Commands to generate dependency files
GEN_DEPS.c=	$(CC) -E -M $(DEFS) $(CPPFLAGS)

## Commands to compile
COMPILE.c=	$(CC) $(DEFS) $(CPPFLAGS) $(CFLAGS) -qroconst -c
COMPILE.cc=	$(CXX) $(DEFS) $(CPPFLAGS) $(CXXFLAGS) -qroconst -c

## 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) -brtl $(DEFS) $(CPPFLAGS) $(CXXFLAGS) $(LDFLAGS)
LINK.cc=	$(CXX) -brtl $(DEFS) $(CPPFLAGS) $(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=	xlC_r -qmkshrobj -G -bh:5
