Hi,
When compiling my kernel in C, I ran on one nasty problem: If the whole command line (path to GCC, GCC.EXE + all parameters) are larger than 128 characters, system refuses to execute the C compiler. Adding the parameters to a environment variable (SET gccoptions=blahblah) didn't help.

Any hints?

cygwin + cross compiler

had to say it

Anything like "compile parameters script" doesn't exist?

Have you tried MinGW?

DJGPP and DOS are dated. There is no need to keep kicking a dead horse.

I agree with ucosty. Cygwin + a [wiki]GCC Cross-Compiler[/wiki] is the way to go.

Not really. Because DJGPP is a DOS app, it is subject to all of those limitations. Reason enough to not use it, really.

MinGW is limited to making PE files, if I remember correctly.

edit: beaten to it

Inflater,

I used to use DJGPP until I switched over to cygwin, and I like cygwin much better. If you want, I can give you the pre-compiled binaries for the cross-compiler for the i586-elf/i386-elf if you want them.

I "fixed" it by moving the whole kernel to c:\krn, but that isn't a fix. Can that cross compiler's linker target to binary? If yes... i would be very grateful for it. But I'll try to find it myself first.

id love those binaries, i tried (and failed to get an ELF cross compiler working).

could you attach them?

Experience has taught us that if you can't build a cross compiler then you can't follow instructions to the letter.

well, i got the cross compiler sort of working, but i couldnt get it to link a single elf properly, and i found DJGPP easier.

i keep meaning to migrate, but i jumped on this chance, as it would give me a sure fire way of getting it to work.

Not sure this helps?

Honestly... building a cygwin cross compiler... is all hype... its really really easy and the benefits out weight the time spent 10000 to 1.

For all of you who want a i586-elf cross compiler/binutils set:

I much prefer talking anyone having a problem with the [wiki]GCC Cross-Compiler[/wiki] tutorial through, instead of providing ready- built binaries. The source for such binaries might go away, leaving the person in question with no way to update his toolchain. Moreover, it gives the impression that there might be anything difficult involved, making newcomers avoid the tutorial when there's no need...
