Try to compile Subsurface and bundle it as an AppImage on CentOS 6

build-inside-centos-6.sh

Moved to https://github.com/probonopd/AppImages/blob/master/recipes/subsurface.centos6.sh

buildhost-centos-5.sh

# THIS DOES NOT WORK, uSE THE ONE AT https://github.com/probonopd/AppImages/blob/master/recipes/subsurface.centos6.sh

# Cannot use CentOS-5.6-x86_64-LiveCD.iso since it uses squashfs3 which 
# cannot easily be mounted by later systems.
# So I have tried the following, but it seems like a lot of work is required
# to make Subsurface build on CentOS 5.

sudo su

mkdir -p /tmp/unionfs/rw
mkdir -p /tmp/union

apt-get -y install rinse
rinse --distribution  centos-5 --arch amd64 --directory /tmp/unionfs/root
# or
# mock -v -r epel-6-x86_64 --init

unionfs-fuse -o allow_other,use_ino,suid,dev,nonempty -ocow,chroot=/tmp/unionfs/,max_files=32768 /rw=RW:/root=RO /tmp/union

mount -t proc proc /tmp/union/proc
mount --bind /var/lib/dbus /tmp/union/var/lib/dbus
touch /tmp/union/etc/resolv.conf || echo ""
mount --bind /etc/resolv.conf /tmp/union/etc/resolv.conf
xhost local: >/dev/null 2>&1 # otherwise "cannot open display: :0.0"

# cat /etc/*release
# CentOS release 5.11 (Final)

yum -y install epel-release
yum -y install wget keyutils-libs git sudo tar gzip which p7zip make autoconf automake

# Fake sudo so that scripts using it can run
echo "" > /usr/bin/sudo
