Hi Jeff, Hi Avi

Thank you very much for your replies.
I added the flags to use the new linker, and now the warning is gone.

If you upgrade to Xcode 4.4 then ld was taught the tricks that ld_classic had to use for i386 kexts and then you won't see that message. If you don't upgrade, the message is harmless.

Well, actually, I can't upgrade to XCode 4.4, due to a framework issue.
(see: http://prod.lists.apple.com/archives/xcode-users/2012/Aug/msg00137.html)

But now I think about it, after some trials I was eventually stuck on a linker error… could it be so simple ?
Do you know the reverse flag name ? I mean, how, to use the previous "old" linker on Xcode 4.4 ?
(This issue is also the one tying me down to 10.7 btw)

Best regards,
Jean

Hi Jean.

You can make Xcode use the new linker with OTHER_LDFLAGS = "-Wl,-new_linker".

Here's the linker source code that prints the "using ld_classic" warning:

Dear All,

When compiling my kext, I get the following warning :

ld: warning: using ld_classic

I know what ld_classic is. I guess there should be a replacement, but I don't know how to make Xcode use it.
Anyway, my kext is working just fine, should I ignore this warning or further attempt to fix it ?

Best regards,
Jean
