While the majority of Tcllib consists of packages written in pure Tcl
a number of packages also have [term accelerators] associated with them.
[para] These are [syscmd critcl]-based C packages whose use will boost
the performance of the packages using them.
While they are built by default on Unix (see [emph {make install}]),
they are not required, they are [emph optional].
[para] When building the accelerators the normally optional dependency
on [syscmd critcl] becomes required.
If they are built according to the instructions below then they will
also be installed as well.
[para] To build and install Tcllib with the accelerators in a
Unix-like environment invoke:
[example {
./configure
make
# or
make install
# or
make install-binaries
}]
[para] The underlying tool is [file sak.tcl] in the toplevel directory
of Tcllib and the [cmd {make install-binaries}] target is just
a wrapper around
[example {
./sak.tcl critcl
}]
[para] Therefore in a Windows environment instead invoke
[example {
./sak.tcl critcl
./installer.tcl
}]
from within a DOS window, i.e. [syscmd cmd.exe].
[para] [emph Beware] that the directory tree generated by this command
sequence differs from the directory tree generated by
[cmd {make install}] and variants.
[para] [cmd {make install}] generates two package directories, one for
Tcllib, the other for Tcllibc.
[para] The above sequence on the other hand places Tcllibc into a
sub-directory of the Tcllib package directory.
