You probably should inherit from $(CXXFLAGS) here which ensures C++11 compatibility. Note you have to deal with non-g++ host compilers when not bootstrapping so adding -Wno-unused-parameter -Werror=overload-virtual needs to be guarded. > + > +# build all rust/lex files in rust folder, add cross-folder includes > +rust/%.o: rust/lex/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build all rust/parse files in rust folder, add cross-folder includes > +rust/%.o: rust/parse/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/ast files in rust folder > +rust/%.o: rust/ast/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/backend files in rust folder > +rust/%.o: rust/backend/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/expand files in rust folder > +rust/%.o: rust/expand/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/util files in rust folder > +rust/%.o: rust/util/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/hir files in rust folder > +rust/%.o: rust/hir/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/hir/tree files in rust folder > +rust/%.o: rust/hir/tree/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/resolve files in rust folder > +rust/%.o: rust/resolve/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/typecheck files in rust folder > +rust/%.o: rust/typecheck/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/checks/lints files in rust folder > +rust/%.o: rust/checks/lints/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/checks/errors files in rust folder > +rust/%.o: rust/checks/errors/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build privacy pass files in rust folder > +rust/%.o: rust/checks/errors/privacy/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > + > +# build rust/metadata files in rust folder > +rust/%.o: rust/metadata/%.cc > + $(COMPILE) $(RUST_CXXFLAGS) $(RUST_INCLUDES) $< > + $(POSTCOMPILE) > -- > 2.25.1 >
