Whoops! I messed up formatting, here's the same message but formatted
(and some small grammar fixes)
Hey, I'm trying to build a custom kernel so that I can debug it over
real and virtualized systems (i.e., use kdb on real hardware and gdb
in qemu).
My custom kernel has the following configuration
```
$ tail -n 9 path/to/netbsd/src/sys/arch/amd64/conf/DEBUG_KERNEL
# Debug Options options DDB
Hey,
I'm trying to build a custom kernel so that I am able to debug it over real
and virtualized systems (i.e., use kdb on real hardware and gdb in qemu).
My custom kernel has the following configuration
```
$ tail -n 9 path/to/netbsd/src/sys/arch/amd64/conf/DEBUG_KERNEL
# Debug Options
options DDB # in-kernel debugger
options DDB_HISTORY_SIZE=1000 # enable history editing
options KGDB # remote debugger
options KGDB_DEVNAME="\"com\"",KGDB_DEVADDR=0x3f8,KGDB_DEVRATE=9600
makeoptions DEBUG="-g3" # compile full symbol table
# Pull in optional local configuration - always at end
cinclude "arch/amd64/conf/GENERIC.local"
```
The layout of my directory looks like where `src` is the checked out
repository
```
netbsd/
├── obj/
│ ├── destdir/
│ └── releasedir/
├── Run.sh
└── src/
├── bin/
└── ...
```
To compile, I have been using `Run.sh` file contains:
```
#!/usr/bin/
export DESTDIR=/home/jared/Projects/netbsd/obj/destdir
export RELEASEDIR=/home/jared/Projects/netbsd/obj/releasedir
cd src/
./build.sh -u -O ../obj -U -m amd64 -N3 -j24 release kernel=DEBUG_KERNEL
./build.sh -u -O ../obj -U -m amd64 -N3 -j24
install=/home/jared/Projects/netbsd/obj/destdir
```
which yields the following error
```
nbmake[1]: stopped in /home/jared/Projects/netbsd/src/etc
nbmake: stopped in /home/jared/Projects/netbsd/src
ERROR: Failed to make release
*** BUILD ABORTED ***
ERROR: -E must be set for install as an unprivileged user
```
which I remedied by updating `Run.sh` to:
```
#!/usr/bin/
export DESTDIR=/home/jared/Projects/netbsd/obj/destdir
export RELEASEDIR=/home/jared/Projects/netbsd/obj/releasedir
cd src/
./build.sh -u -O ../obj -U -m amd64 -N3 -j24 release kernel=DEBUG_KERNEL
./build.sh -u -O ../obj -U - -E m amd64 -N3 -j24
install=/home/jared/Projects/netbsd/obj/destdir
```
which then yields the following error
```
[ same error repeated ]
