## 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)

# Make the strings readonly. This helps in the common data library
CFLAGS += -qroconst
CXXFLAGS += -qroconst

LDFLAGS += -brtl

## We need to delete things prior to linking, or else we'll get
## SEVERE ERROR: output file in use ..  on AIX.
## But, shell script version should NOT delete target as we don't
## have $@ in that context.  (SH = only shell script, icu-config)

## 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)
