Environment to reproduce 32bits colm compiling error

Note that it needs more than 5GB of free disk space to pull it.

You also can't be running any Virtual Machine at the same time (VirtualBox at least) or the qemu emulator in the Docker won't be able to start (see Error on start at the bottom of this README).

My host system had virtualbox-5.2 installed, which may pull some virtualization related dependencies to make this docker image work... if it doesn't work, you may need to install those.

Pull the image

docker pull awesomebytes/colm_environment:1

Run

docker run --privileged -v $HOME:/shared -it awesomebytes/colm_environment:1

Start the VM with the environment:

# This starts the qemu VM, takes 1min30s for me
./COLM-start

# IMPORTANT!!!!! login into the user when you are in the VM shell, the prompt looks like:
# sh-4.4#
su - abuild
# Now the prompt looks like:
# abuild@localhost:~>

# now go for business
cd ~/rpmbuild/BUILD/colm-0.13.0.5
make clean
./configure
make

# Wait a minute and you'll get:
# ./bootstrap1 -c -o gen/parse2.c -e gen/if2.h -x gen/if2.cc colm.lm
# bootstrap1: tree.c:953: colm_tree_downref: Assertion `tree->refs > 0' failed.

Build if you prefer

You can also build the image yourself, it will take a while as it needs to download a 4GB file and download & install 200mb worth of ubuntu packages.

docker build -t colm_environment .

Then your run command will be instead:

docker run --privileged -v $HOME:/shared -it colm_environment

Error on start

The error in that case is:

ioctl(KVM_CREATE_VM) failed: 16 Device or resource busy
failed to initialize KVM: Device or resource busy
