Most mar csak az ABI version elteres, de azt hiaba allitom. Lefordul, de 1-es marad.<br>

A gcc verzio egyebkent 4.4.6<br>

Feltoltottem a boxra a hello-t little endiannal. Most a hibauzenet:<br>

Latom, big endian es little endian elteres van.<br>
<br>
Gyorasan utannaneztem, marha egyszeru mbig-endian mlittle-endian optiokat kene hasznalni, csak a compiler ezeket nem ismeri.<br>
<br>
Turom meg, hatha ez lesz a jo irany.<br>
