Install instructions This instructions are a rough how to. It might be they are not complete. (If you find something not right or not complete, please report it) Create a directory like: VboXOs2 Copy all files to that directory Copy vboxdrv.sys to X:\os2\boot\vboxdrv.sys (Where X is your driveletter) Add DEVICE=X:\OS2\BOOT\vboxdrv.sys to you're config.sys Check if you have all dependencies with: yum install libc libgcc1 yum install libstdc++6 libstdc++ yum install libsupc++6 libsupc++ yum install libgcc-fwd yum install libqt4 yum install zlib yum install pthread yum install libaio yum install libvpx yum install libvncserver yum install libpng libjpeg yum install libidl yum install mmap urpo yum install libxml2 expat curl yum install openssl yum install SDL yum install glib2 yum install libcx Check with pmdll virtualbox.exe if all dll are loadable (pmdll is found on hobbes) Start Virtualbox.exe and you see the Qt Gui (note: not all features work so far, like the mouse integration) If you want the mouse integration you better use the SDL interface For the SDL interface you need to create an image first and then start it: VBoxManage.exe createvm --name Example --register VBoxManage.exe storagectl Example --name IDE --add ide --controller PIIX3 --portcount 2 VBoxManage.exe storageattach Example --storagectl IDE --port 0 --device 1 --type dvddrive --medium Example.iso VBoxSDL.exe -s Example Please replace Example by you're needs. But be aware that the name is case sensitive. So example is not like Example and will give you an error. Build instructions This current version of the configure script requires the RPM/YUM environment and the following develompent setup: yum install ash which kbuild gcc gcc-wlink gcc-wrc gettext-devel pthread-devel libxml2-devel libxslt-devel openssl-devel libcurl-devel zlib-devel libpng-devel libqt4-devel libidl-devel libvncserver-devel nasm libpoll-devel libaio-devel SDL-devel glib2-devel libcx-devel mkisofs.exe from __http://hobbes.nmsu.edu/download/pub/os2/apps/mmedia/cd/cd-r/cdrecord-2_00_os2.zip in PATH OpenWatcom 1.9 (from here I believe: __ftp://ftp.openwatcom.org/pub/open-watcom-c-os2-1.9.exe) ash from RPM as the current shell The configure script from the root of the source tree should be run as follows (under ash): export WATCOM= ./configure --with-ow-dir=$WATCOM --enable-vnc --disable-docs You may also want to add an optional --out-path=DIR so that all build results will go to DIR instead of polluting the source tree.
