Installation of SVGAlib

Note

You must compile and install as root. If you don't nothing bad will happen during compilation, but certain tools won't be able to become SUID root which is required for proper operation. However, this raises a risk of exposing your system to any holes in those tools that might be used to gain root access so use with caution.

Install SVGAlib by running the following commands:

patch -Np1 -i ../svgalib-1.4.3-gcc3-1.patch &&
make prefix=/usr install &&
cd doc &&
for dir in man?; do for file in $dir/*; do \
gunzip /usr/share/man/$file; done; done

Command explanations

cd doc && for dir in man?; do for file in $dir/*; do gunzip /usr/share/man/$file; done; done: SVGAlib installs it's man pages in compressed format so we uncompress them.

Configuring SVGAlib

Config files

/etc/vga/libvga.config, ~/.svgalibrc

Configuration information

You must edit the config file to set the monitor and mouse type. Depending on your hardware, other setup might be required.

As with most libraries, there is no configuration to do, save that the library directory i.e. /opt/lib or /usr/local/lib should appear in /etc/ld.so.conf so that ldd can find the shared libraries. After checking that this is the case, /sbin/ldconfig should be run while logged in as root.
