Tcllibc is a term used to refer to the parts of Tcllib written in C. Some packages in Tcllib provide two implementations, one written in pure Tcl for compatibility and low installation overhead and one written in C for speed.

ActiveTcl has a separate Tcl Extension Archive package called Tcllibc .

The C parts of Tcllib can be build either via

configure ; make critcl


./sak.tcl critcl
