TIP

As of Simile version 5.0, glibc version 2.4 is required to run the Linux Simile build available from simulistics.com. (If you have an earlier version we may be able to build Simile for you. Let us know the version of glibc you have and other details of your Linux distribution.)

To find the version of glibc on most systems, including Debian, call the library as a program:

(uiserver)::~ > /lib/libc.so.6
GNU C Library stable release version 2.3.6, by Roland McGrath et al.

On Debian-based systems:

Use undo/redo

When editing a model it can be easy (as is often the case with diagram editors) to make an addition or change you immediately wish you hadn't made. Returning the diagram to how it was before the change manually can be a nuisance involving several mouse manipulations and/or key clicks. Any change can be undone by using the undo button on the toolbar or pressing Ctrl z. You can undo changes incrementally by repeated undo operations and if you change your mind there is a redo button.

This is one of the most common constructions. The rate of change of the state variable is a function of its present value.
