View source for Old operating systems

__NOTOC__
Modeller has a few prerequisites which should generally be satisfied on modern operating systems. If, however, you have a very old operating system, workarounds are detailed on this page.

== [[RedHat]] 8.0 ==

Modeller requires the [http://www.gtk.org/ glib library] version 2.2 or later, but RedHat 8.0 ships with glib 2.0. (When trying to run Modeller, you will see an error like the following: `mod9v2_i386-intel8: relocation error: libmodeller.so.1: undefined symbol: g_vsprintf`)

For a simple workaround, you can copy the glib library from RedHat 9 into your Modeller installation. For example, for 32-bit RedHat 8.0, just get `/usr/lib/libglib-2.0.so.0` from a RedHat 9 system (can also be [[attachment:libglib-2.0.so.0|downloaded from our website]]) and put it in the `lib/i386-intel8` directory under your Modeller installation. (If you installed from RPM, this will be `/usr/lib/modeller9v2/lib/i386-intel8/` or similar.) To install the RPM in the first place, add the `--nodeps` option (otherwise it will complain that it needs glib2 >= 2.2).
