Liming yes, you are correct. I updated the [C-Code-File] rule build_rule.txt
file to build from the WORKSPACE directory when I changed from ${src} to
${relsrc}
<Command.XCODE>
cd $(WORKSPACE); "$(CC)" $(INC) $(CC_FLAGS) -o ${dst} ${relsrc}
The way GNU make works this cd is only for the subprocess that executes the
$(CC) command and it is not global.
