Hallo Leute,
mein Vorhaben:
Hello World Programm in C schreiben und auf dem BeagleBoard ausführen.
Host: ubuntu-10.04-desktop-i386, läuft bei mir als VirtualMachine.
Target: BeagleBoard -> ARMv7.
Nun bin ich nach dieser Anleitung vorgegangen:
http://embdev.net/articles/ARM_GCC_toolchain_for_Linux_and_Mac_OS_X
mein Code:
1 |
|
2 | #include <stdio.h>
|
3 |
|
4 | int main (void) {
|
5 | printf("Hello World\n");
|
6 | }
|
Der Befehl zum Compilieren:
1 | arm-elf-gcc hello.c -o hello
|
Fehlermeldung:
1 | /usr/local/arm/lib/gcc/arm-elf/4.1.0/../../../../arm-elf/lib/libc.a(mallocr.o): In function `_malloc_r':

Müsste aber doch eigenlich alles stimmen? Oder habe ich etwas übersehen?
Wo liegt der Fehler? :)
