## Please note: AIX does NOT have library versioning per se (there is no 'SONAME' capability). 
## So, we are using 'windows' style library names, that is, libicuuc20.1.so instead of libicuuc.so.20.1

## Commands to generate dependency files
GEN_DEPS.c=	$(CC) -E -M $(DEFS) $(CPPFLAGS)
GEN_DEPS.cc=	$(CXX) -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
SHLIB.c=	$(AIX_SHLIB) -p 5000 -brtl $(LDFLAGS)
SHLIB.cc=	$(AIX_SHLIB) -p 5000 -brtl $(LDFLAGS)
