Cross Compiler problem

I knew it was no good idea to reinstall Cygwin...
As i was exactly following the instructions in the tutorial (downloaded latest versions of binutils and gcc-core), in the step 'make all' of bootstrapping binutils, this was the output:
Code: Select all
make[1]: Entering directory '/usr/src/build-binutils'
mkdir --p -- ./libiberty
Configuring in ./libiberty
Configure: error: invalid feature name: nls
make[1]: *** [configure-libiberty] Error 1
make[1]: Leaving directory '/usr/src/build-binutils'
make: *** [all] Error 2
As for the nls, I did use --disable-nls in the configure process. Googling for 'invalid feature name nls make' didn't help, either.
Thanks for your help

Are you sure you obtained these sources from the PROPER location? via official mirrors not the "Cygwin" modified sources.
http://ftp.gnu.org/gnu/binutils/
http://ftp.gnu.org/gnu/gcc/
I'm positive you'll find the right archives above lol
(
Also, Post your complete ./configure command next time as it's not possible to us to read minds..)

Sorry, but I did get my archives from the GNU website:
http://ftp.gnu.org/gnu/binutils/binutils-2.17.tar.bz2
http://ftp.gnu.org/gnu/gcc/gcc-4.2.0/gc ... .0.tar.bz2
Is there a chance the procedure doesn't work with this versions? (GCC 4.2.0 isn't mentioned in the Wiki, I did, however, get binutils 2.17 which is mentioned in the wiki and was stuck at bootstrapping binutils, not gcc).
(Also, Post your complete ./configure command next time as it's not possible to us to read minds..)
Sorry; here it is (the one from the Wiki, which is the one I used):
Code: Select all
../binutils-2.17/configure --target=$TARGET --prefix=$PREFIX --disable-nls
Thanks

Edit: I have now tried a few things... I installed bison, flex and byacc because I remember that I had them too on my old installation... I tried setting the target to i386-elf and i486-elf instead of i586-elf... but the error message is always the same... I also took a look at the configure output, and there it stated that it needed a program called cmp but didn't find it and cmp wasn't on the package list in setup.exe...

It's supposedly part of the rootkit. A default cygwin install should provide it. Installing again cleanly from a different mirror might solve that (it fixed my install a few times already
)

Hi,
You're not the only one - I have tried the build with 4.2.0 and have exactly the same problems. Having said that, the same happens with 4.1.2. If I follow the instructions with Damn Small Linux running in Virtual PC, no problems - but I am much more familiar with Windows for devving.

A few days/weeks ago, someone kindly posted a zipped version of their cleanly-built "/usr/cross" directory which worked very well for me. If anyone wanted to do that for a version including g++ too, that would be extremely nice of them...
Cheers,
Adam

I posted a cygwin hosted cross compiler targeting i586-elf, based upon gcc 4.1.2 and binutils 2.17. Its available
here but I'd really appreciate it if someone mirrored it somewhere with a better bandwidth as at the moment its just running off my server sitting next to me with a rather slow upstream. The page above has one known problem (+ fix) with the package - if anyone else finds other problems please let me know.

Might do, if I get a chance. I don't use c++ for my os, so didn't bother, and at the time I created the last archive it was in response to a request for a small download for someone who had a dial-up connection, so I tried to keep it as small as possible.
Regards,
John.

GNU 4.1.2 C++ cross compiler running on Windows available
here. Again, if anyone could mirror these I'd be grateful. Note that I haven't tested the C++ compiler in this package, except by running the --version command, which seems to work. The C compiler is also included and seems to work okay at compiling my kernel.
Regards,
John.

Fantastic, thank you!
If I find somewhere to host these files, are you happy for me to distribute them for others?

Of course, please could you test them first though. They're under the GPL after all.

OK.
So far I have compiled a few elf test binaries and my kernel's exe loader seems to load them fine. I'll do a few more tests then scratch around for some bandwidth
I'm currently a very happy bloke!
Cheers,
Adam

@Candamir
When you reinstalled cygwin did you set the mode to text? It must be set to binary in order to build gcc and binutils.

Thank you all, I could solve my problem. The problem was (as frank pointed out) that my Cygwin was running in text mode and I had to run setup.exe again in order to enable binary / UNIX mode.
Thanks

Edit: Maybe this would be worthy for the wiki article, but I haven't yet been approved as an editor, so I'll do it when my application gets through or maybe someone else would do it?

Hi,
For anyone who is interested, as I was, a link to the crosscompiler provided by jnc100 is now in my sig. I switched it to zip format. Much as I think anyone owning Windows should have 7 zip (which provides much better compression), I did it so that anyone using XP+ can just open the folder directly.
Cheers,
Adam
