I've encountered the following problem when I compiled the source code of lesson Input01:
But it performed correct when I compiled the code of the former lessons.
Code: Select all
jack@jack-Lenovo-G475:~/deskdop/input01$ make arm-none-eabi-as -I source/ source/mailbox.s -o build/mailbox.o Assembler messages: Fatal error: can't create build/mailbox.o: No such file or directory Makefile:57: recipe for target 'build/mailbox.o' failed make: *** [build/mailbox.o] Error 1 jack@jack-Lenovo-G475:~/deskdop/input01$
Who can tell me how to do with it ?
