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.
Thanks,
Chris.
