Unable to load /system/startup.js from initrd

I'm getting this error when trying to start

jacob-mbp:runtime jacob$ ./qemu.sh
Unable to load /system/startup.js from initrd.
Kernel error: abort() requested

Looks like there is something wrong with your initrd image. Have you changed content of initrd directory? It's unable to locate file initrd/system/startup.js.

Image located at disk/boot/initrd. You can rebuild it

./makeinitrd.sh

Or using docker

docker run --rm -w /mnt -v $(pwd):/mnt:rw runtimejs ./makeinitrd.sh

Or you can send me your image file and I'll look into it.

I think my mkinitrd is broken

vagrant@precise64:/vagrant/runtime$ ./mkinitrd -c disk/boot/initrd initrd
vagrant@precise64:/vagrant/runtime$ echo $?
0
vagrant@precise64:/vagrant/runtime$ hexdump -C disk/boot/initrd

vagrant@precise64:/vagrant/runtime$ 

I tried rm mkinitrd and then sudo docker-build.sh again, but same result :frowning:

It actually created an empty image. Looks like it's unable to access initrd files.

Try this without docker:

g++ -std=c++11 -O3 src/mkinitrd/mkinitrd.cc src/common/package.cc src/common/crc64.cc -Isrc -o mkinitrd
./mkinitrd -c disk/boot/initrd initrd

vagrant@precise64:/vagrant/runtime$ g++ -std=c++11 -O3 src/mkinitrd/mkinitrd.cc src/common/package.cc src/common/crc64.cc -Isrc -o mkinitrd
cc1plus: error: unrecognized command line option '-std=c++11'
cc1plus: error: unrecognized command line option '-std=c++11'
cc1plus: error: unrecognized command line option '-std=c++11'

Try replacing c++11 with C++11.

Maybe I should update my system, thoughts?

vagrant@precise64:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu

I upgraded to Ubuntu 14.04, but the same problem is happening. It looks like my initrd is empty.

[groundwater]

@iefserge I think may be the ./mkinitrd -c disk/boot/initrd initrd command is not working. It exits immediately without any output, but returns exit code 0.

[tany2001]

Are you sure you are running the ./mkinitrd -c .... command with the correct permissions? If you have cloned the repository like root, but you are running the command like a normal user, then mkinitrd command will not create anything.

@tany2001 I had the runtime project mounted through vagrants shared folders. I copied the directory into my Ubuntu home directory, and everything built.

tl;dr don't use vagrant's shared mounts

@tany2001 @iefserge thanks for the help
