Hi all,

Last week, I started to use MacOSX, and I tried to
build kernel(XNU).
But I have a serious problem.
When I try to build cctools, I get following error message.

%sudo make RC_OS=macos kld_build
cc -g -I.. -I../../include -I. -Wall -Wno-precomp -Wno-long-double -static -DRLD -DKLD -fno-builtin -finline -fno-keep-inline-functions -fsigned-bitfields -force_cpusubtype_ALL -msoft-float -nostdinc -I/System/Library/Frameworks/Kernel.framework/Headers/libsa -I/System/Library/Frameworks/Kernel.framework/Headers/bsd -I/System/Library/Frameworks/Kernel.framework/Headers -DKERNEL -DKERNEL_PRIVATE -DAPPLE -DNeXT -DLIBSA_PRIVATE -O -c -MD \

/System/Library/Frameworks/Kernel.framework/Headers/sys/file.h:63: header file 'sys/unistd.h' not found
cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode
make[1]: *** [pass1.o] Error 1
make: *** [kld_build] Error 2

Truely, there is no such a header file.
How can I get the file? Please help me.

I have unistd.h in 10.2. Make sure you install the BSD subsytem and the latest version of dev tools.

code:


/usr/include/sys/unistd.h
/usr/include/unistd.h

I have installed the latest version of DeveloperTools.
I have /usr/include/sys/unistd.h and /usr/include/unistd.h.
I think cctools requires
/System/Library/Frameworks/Kernel.framework/Headers/sys/unistd.h.
Do you have this one? If you have, did you do something special?

>Make sure you install the BSD subsystem
I don't know what is the BSD subsystem and where to get that.

BSD subsystem is part of OS X...it's on the install CD.

unfortunately it was errantly not included in the kernel framework. you can resolve this issue with:

code:

% sudo cp /usr/include/sys/unistd.h \
/System/Library/Frameworks/Kernel.framework/Headers/sys/

additionally, i have thrown together some of my notes into a doc for building xnu -- this might be helpful: http://www.opendarwin.org/~jpm/xnu.html
