kann mir da mal jemand helfen ??

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".
#----------------------------------------------------------------------------


# MCU name
MCU = atmega8


# Processor frequency.
#    This will define a symbol, F_CPU, in all source code files equal to the
#    processor frequency. You can then use this symbol in your source code to
#    calculate timings. Do NOT tack on a 'UL' at the end, this will be done
#    automatically to create a 32-bit value in your source code.

#    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,
#    it will preserve the spelling of the filenames, and gcc itself does
#    care about how the name is spelled on its command-line.

und hier der quellcode, der nur mal ein beispiel sein soll um die einstellungen zu testen:

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
}

Code-Tags ! PicNick

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

Zitat:

SRC = $(TARGET).c C:/AVR_ATmega8/Projekte/training/C/helloc.c

---

mal aus, durch das

Zitat:

---

TARGET = helloc

---

wird die Datei nämlich schon eingebunden. Du verwendest sie quasi doppelt.

Danke erstmal, mittlerweile siehts schon wieder anders aus,
Ich bekomm jetzt diese Fehlermeldung:

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>

int main(void)

return 0;

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'<<

Andun

ups, stimmt natürlich

ich hab in der Zeile

Zitat:

---

SRC = $(TARGET).c C:/AVR_ATmega8/Projekte/training/C/helloc.c

---

irgendwie nur das Ende angeschaut... ](*,)

einmal muss helloc.c schon eingebunden werden...

Also Danke für die Antworten. Inzwischen bin ich Herr der Lage...
