Thanks....
Yet I wasn't able to do this compilation...
I runned GCC to compile, I runned GCC/LD+ELFADORN to link... but it does not
work. (I've got an elf who refuse to merge with the same mistake).
" ~/okl4_2.1/tools/pyelf/elfadorn -s -o hello.elf --
~/opt/nicta/gcc-3.3.4-glibc-2.3.3/i686-unknown-linux-gnu/bin/i686-unknown-linux-gnu-gcc
hello_world_elf.o -o hello.elf -lc -lgcc"
Then my question is : what kind of args should I had to GCC, GCC/LD or
Elfadorn to produce an Elf for OKL4 ?
Thanks
Antonin
