Problem beim kompilieren:
Hi,
ich habe eine Zeit lang keine große Lust gehabt mich in die C-Programmierung meines AVR einzuarbeiten. Jetzt hab ich sie wieder und hab gerade die ganzen Packages unter Suse Linux 10.0 installiert, die man so braucht, also gcc-core, avr-libc, uisp, binutils. Dann wollte ich das Testprogramm das man auf http://www.tldp.org/linuxfocus/Engli...ticle352.shtml findet kompilieren, die Fehlermeldung lautete:
Code:
linux:/home/mathias/Desktop # make
avr-gcc -g -mmcu=atmega8 -Wall -Wstrict-prototypes -Os -mcall-prologues -Os -c avrm8ledtest.c

Ich poste auch mal das Makefile und den Code, weiß nicht ob das hilft aber schaden kanns ja nicht:

Das Problem ist eben auch, dass ich weder den Code verstehe, noch weiß was die Sache mit dem Makefile soll. Also Ahnung von Programmieren hab ich schon allerdings nur in Java :D (hilft mir ja hier nicht weiter schätz ich mal)
Ich hoff ihr könnt mir helfen.
