Re: [Cdemu-devel] vhba trouble

[Rok M. <rok...@gm...>]

On debian, I would advise you to use the provided build scripts (debian 
subfolder in each component's folder) to build .deb packages and install 
those:

git clone git://git.code.sf.net/p/cdemu/code cdemu-code
cd cdemu-code

# VHBA
cd vhba
apt-get build-dep . # Run as root; should install all build dependencies
dpkg-buildpackage -b -tc -uc # Builds the package
cd ..
apt install ./vhba-dkms_20170610-1_all.deb # Run as root to install the 
package

modinfo vhba # Check if module was automatically built for the current 
kernel

# libmirage
cd libmirage
apt-get build-dep . # Run as root; should install all build dependencies
dpkg-buildpackage -b -tc -uc # Builds the package
cd ..
apt install ./libmirage11_3.2.0-1_amd64.deb 
./libmirage11-dev_3.2.0-1_amd64.deb 
./gir1.2-mirage-3.2_3.2.0-1_amd64.deb # Install libMirage before trying 
to build cdemu-daemon package

# Same steps for cdemu-daemon, cdemu-client, gcdemu: same

The .deb packages provide additional configuration for setting 
permissions and module auto-load, which you will be missing if you do a 
manual build from source. And incorrectly set permssions on VHBA control 
device will be one of the reasons for cdemu-daemon to refuse to start.
