I sent this to the darwin drivers list, but I realize now that this
is definitely an Xcode question:
I am trying to build universal IOKit KEXTs on a PowerPC machine
using Xcode 2.2.1.
I have set up the properties meticulously according to the Technote
that describes the process:
GCC_VERSION_i386 = 4.0
GCC_VERSION_ppc = 3.3
MACOSX_DEPLOYMENT_TARGET_i386 = 10.4
MACOSX_DEPLOYMENT_TARGET_ppc = 10.2
SDKROOT_i386 = /Developer/SDKs/MacOSX10.4u.sdk
SDKROOT_ppc = /Developer/SDKs/MacOSX10.2.sdk
and I have applied all the other recommended changes as well. I have
been through it several times. I am sure I haven't missed anything.
The PowerPC half builds fine. But when I try to build the Intel half
I get this message:
/System/Library/Frameworks/Kernel.framework/PrivateHeaders/
architecture/byte_order.h:37:42: error: architecture/i386/
byte_order.h: No such file or directory
and a bunch of others.
Looking at the command used by Xcode to build one of the files, I
see the following option:
-I/System/Library/Frameworks/Kernel.framework/PrivateHeaders
This is the problem. If I copy the command to the terminal and
remove the above include path, the file in question will compile.
(In fact, if I compile every file manually, I can actually build my
project).
So my questions are: how did that path get put on the command line,
and how do I get rid of it? I am not specifying it anywhere -it
would appear to be something Xcode is adding.
At least one other person asked about this on one of the lists, but
he didn't get an answer. I hope someone can help.
Also note that if you copied and pasted the value for the SDKROOT_ppc,
it's incorrect. It should be /Developer/SDKs/MacOSX10.2.8.sdk (not
10.2.sdk)
Failing to find the SDK will make Xcode revert to /, and could
contribute to the problem you're seeing.
