    warum muss mein Quellcode immer test.c heißen???

    Anzeige

    Powerstation Test
    Servus leutz,

    also i versuche gerade mal mit Hilfe von Programmers Notepad einzustellen, dass mein *.c datei nicht immer test.c heissen soll.
    aber wenn i die im makefile ändere, dann kann i trotzdem nicht kompilieren.

    Kann mir da jemand weiterhelfen???

    Gruß Robots

    Schau mal, ob im Makefile versucht wird test.o zu linken. Das muss dann ebenfalls noch angepasst werden. (oder poste mal das makefile).

    Poste doch mal das Makefile.

    Hier mal das Makefile

    Code:
     # WinAVR Sample makefile written by Eric B. Weddington, Jörg Wunsch, et al.
    # Released to the Public Domain
    # Please read the make user manual!
    #
    #
    # On command line:
    #
    # make all = Make software.
    #
    # make clean = Clean out built project files.
    #
    # make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).
    #
    # make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio
    #                4.07 or greater).
    #
    # make program = Download the hex file to the device, using avrdude.  Please
    #                customize the avrdude settings below first!
    #
    # make filename.s = Just compile filename.c into the assembler code only
    #
    # To rebuild project do "make clean" then "make all".

    MCU = atmega8
    
    # Output format. (can be srec, ihex, binary)

    TARGET = test
    
    # Optimization level, can be [0, 1, 2, 3, s]. 0 turns off optimization.
    # (Note: 3 is not always the best optimization level. See avr-libc FAQ.)
    OPT = s
    
    
    # List C source files here. (C dependencies are automatically generated.)
    SRC = $(TARGET).c

    # uncomment the following:
    SRC += asuro.c
    
    # You can also wrap lines by appending a backslash to the end of the line:
    #SRC += baz.c \
    #xyzzy.c
    
    
    
    # List Assembler source files here.
    # Make them always end in a capital .S.  Files ending in a lowercase .s
    # will not be considered source files but generated files (assembler
    # output from the compiler), and will be deleted upon "make clean"!
    # Even though the DOS/Win* filesystem matches both .s and .S the same,

    Du musst eigentlich nur in der Zeile

    TARGET = test

    test durch den name (ohne '.c') der Datei ersetzen, die die main() Funktion enthält.

    Falls das nicht klapp, poste mal die Fehlermeldungen.

    Poste mal das makefile bei dem der Fehler auftritt und den output auf der Kommandozeile.

    'make clean' hilft vielleicht, um die dependencies Files zu loeschen.

    Warum nehmt ihr nicht AVR-Studio? Damit hat man die ganzen Probleme nicht.

    Gruss,
