Has anyone been able to do kernel development on OSX? I'm trying to
build a kernel with debugging enabled. The Android documentation makes
Darwin/OSX sound like it is fully supported, but I'm running into a
lot of problems that make me suspect either I'm doing this the hard
way or the rest of the Android kernel hackers are using Linux perhaps.
When I tried to run 'make menuconfig" I received the following error:
$ make menuconfig
*** Unable to find the ncurses libraries or the
*** required header files.
*** 'make menuconfig' requires the ncurses libraries.
***
*** Install ncurses (ncurses-devel) and try again.
***
make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
make: *** [menuconfig] Error 2
This article http://lkml.org/lkml/2008/4/28/460 pointed out that OSX's
echo does not jive well with the kernel script:
myandroid/kernel/scripts/kconfig/lxdialog
After commenting out the error, I was able to get menuconfig to run:
#exit 1
However, when I try to build the kernel I got another error about my
version of sed:
sed: 4: "/^\#define/ { s/[^_]*__ ...": bad flag in substitute
command: '}'
This I was able to avert by using Fink to install the GNU version of
sed.
Now I'm stuck with the following build errors:
