I got a fresh source code from the website, and tried to compile (my install was compiling fine earlier), and i get this error wich i have no idea as to why it happens... Any pointers?

Hmm, usually these new warnings pop up when someone's using a newer version of gcc.

You can prevent them from stopping the build by removing the -Werr option from the makefiles (I prefer not to allow warnings to go unfixed, but I'm fussy).

You can probably solve these particular warnings by changing the %02x ones on lines 536 and 543 to %02lx, and the %d one on line 549 to %lu

[ap0r]

One step forward! (Ti the next error anyways)

So, i fixed the source as per instructed above, but Nasm doesn't like these new files? I'm waaay in over my head right now... Learning! yay!

Ahh, I considered last night that maybe you were getting those other warnings because you're on a 64-bit system . I don't see those because my dev system is 32-bit.

It looks as though your linker, ld, is expecting to link 64-bit .o files, but NASM is (correctly) producing 32-bit ones. I think you should be able to tell the linker (via gcc) to produce 32-bit output by doing adding the following argument in the makefiles:

Code: Select all

-m,elf_i386

so link arguments passed via gcc - in this case - would look like:

Code: Select all

-Wl,-warn-common,-X,--oformat,binary,-e,loaderMain,-Ttext,0x00000000,-m,elf_i386

Can you let us know whether that helps?

Yup, it seems i accidentaly downloaded a 64 bit iso for my linux

Downloading 32 bit version as we speak

[ap0r]

32 bit solved it
