    kann mir da mal jemand helfen ??

    Anzeige

    HI, ich bin heut von assembler auf c umgestiegen und bin grade dabei
    die winavr tools zum laufen zu bringen, bzw. kämpfe mit "make". Soweit sollte eigentlich alles stimmen, bis auf folgendes:

    Compiling: helloc.c
    avr-gcc -c -mmcu=atmega8 -I. -gdwarf-2 -DF_CPU=3600000UL -O0 -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -Wall -Wstrict-prototypes -Wa,-adhlns=helloc.lst -std=gnu99 -MD -MP -MF .dep/helloc.o.d helloc.c -o helloc.o

    make.exe: *** No rule to make target
    `C:/AVR_ATmega8/Projekte/training/C/C_first_helloc.o', needed by `helloc.elf'. Stop.

    > Process Exit Code: 2
    > Time Taken: 00:01

    was mir probleme macht, ist die angabe der regeln für make. Im moment steh ich damit ziemlich im regen. evtl. ist es ja etwas ganz simples.

    Vielen dank schon mal für alles anregungen

    mfg,

    lc

    erstmal: bitte Titel etwas aussagekräftiger gestalten!

    dann: bitte mal Quellcode und vor allem das Makefile posten...

    Ja klar, beim nächsten mal.

    Also hier erst das Makefile:
    Code:
    #----------------------------------------------------------------------------
    # On command line:
    #
    # make all = Make software.
    #
    # make clean = Clean out built project files.
    #
    # make coff = Convert ELF to AVR COFF.
    #
    # make extcoff = Convert ELF to AVR Extended COFF.
    #
    # make program = Download the hex file to the device, using avrdude.
    #                Please customize the avrdude settings below first!
    #
    # make debug = Start either simulavr or avarice as specified for debugging, 
    #              with avr-gdb or avr-insight as the front end for debugging.
    #
    # make filename.s = Just compile filename.c into the assembler code only.
    #
    # make filename.i = Create a preprocessed source file for use in submitting
    #                   bug reports to the GCC project.

    # To rebuild project do "make clean" then "make all".

    im Abschnitt

    # List C source files here. (C dependencies are automatically generated.)
    SRC = $(TARGET).c

    steht bei dir noch der Verweis auf C:/AVR_ATmega8/Projekte/training/C/helloc.c
    Wenn jetzt in diesem Verzeichnis kein Makefile dafür gefunden wird, gibts die Fehlermeldung.
    Du bindest hier die Hauptdatei gleich zweimal ein, zunächst über $(TARGET).c, und dann nochmal über deinen Pfad. Einmal reicht, und wenn eine Datei im selben Verzeichnis liegt wie der Rest, braucht man nur den Namen angeben.

    Mit
    # List C source files here. (C dependencies are automatically generated.)
    SRC = $(TARGET).c
    funktioniert alles einwandfrei.

    Kommentier das
    SRC = $(TARGET).c C:/AVR_ATmega8/Projekte/training/C/helloc.c
    mal aus, durch das
    TARGET = helloc
    wird die Datei nämlich schon eingebunden. Du verwendest sie quasi doppelt.

    Ich bekomm jetzt diese Fehlermeldung:

    Linking: helloc.elf

    H:/WinAVR/bin/../lib/gcc/avr/3.4.5/../../../../avr/lib/avr4/crtm8.o: In function `__vectors':
    ../../../../../avr-libc-1.4.3/crt1/gcrt1.S:51: undefined reference to `main'
    make.exe: *** [helloc.elf] Error 1

    Hat anscheinend was mit der library zu tun, aber meine Erfahrung mit winavr ist ja noch sehr beschränkt...


    Hier nochmal der code:
    ------------------------------------------------------------------
    #include <avr/io.h>

    #define SYSCLK 3686400

    void init(void);

    int main(void)
    {

    init();

    return 0;
    }

    // Initialisierung
    void init(void)
    {

    DDRB = 0xff; // PortB als Ausgang deklarieren
    PORTB = 0x00; // Ports auf LOW schalten

    }

    Zitat Zitat von Pascal
    Kommentier das
    SRC = $(TARGET).c C:/AVR_ATmega8/Projekte/training/C/helloc.c
    mal aus, durch das
    TARGET = helloc
    wird die Datei nämlich schon eingebunden. Du verwendest sie quasi doppelt.
    Also so stimmt das auch nicht ganz. Es muss nur der hintere Teil auskommentiert werden. Es sollte dann so aussehen:

    Code:
    TARGET = helloc
    SRC = $(TARGET).c
    Die Fehlermeldung sieht mir einfach danach aus, dass er main() nicht finden kann. >>undefined reference to `main'<<

    ups, stimmt natürlich

    ich hab in der Zeile
    SRC = $(TARGET).c C:/AVR_ATmega8/Projekte/training/C/helloc.c
    irgendwie nur das Ende angeschaut...

    einmal muss helloc.c schon eingebunden werden...
