Tcl-8.4.9

Introduction to Tcl

The Tcl package contains the Tool Command Language, a robust general-purpose scripting language.

Package information

Installation of Tcl

[Note]

Note

This package is also installed in LFS during the bootstrap phase. The significant difference between the two installations (other than installing to /usr) is the package is installed in such a way that there is no need to keep the build directory around after installation.

Install Tcl by running the following commands:

export VERSION=8.4.9 &&
export V=`echo $VERSION | cut -d "." -f 1,2` &&
export DIR=$PWD &&
cd unix &&
./configure --prefix=/usr --enable-threads &&
make &&
sed -i "s:${DIR}/unix:/usr/lib:" tclConfig.sh &&
sed -i "s:${DIR}:/usr/include/tcl${V}:" tclConfig.sh &&
sed -i "s,^TCL_LIB_FILE='libtcl${V}..TCL_DBGX..so',\
TCL_LIB_FILE=\"libtcl${V}\$\{TCL_DBGX\}.so\"," tclConfig.sh

Now, as the root user:

make install &&
install -d /usr/include/tcl${V}/unix &&
install -m644 *.h /usr/include/tcl${V}/unix/ &&
install -d /usr/include/tcl${V}/generic &&
install -c -m644 ../generic/*.h /usr/include/tcl${V}/generic/ &&
rm -f /usr/include/tcl${V}/generic/{tcl,tclDecls,tclPlatDecls}.h &&
ln -nsf ../../include/tcl${V} /usr/lib/tcl${V}/include &&
ln -sf libtcl${V}.so /usr/lib/libtcl.so &&
ln -sf tclsh${V} /usr/bin/tclsh

Clean up the unprivileged user's environment using the following commands:

unset VERSION &&
unset V &&
unset DIR

Command explanations

--enable-threads: This switch forces the package to build with thread support.

sed -i ...: The Tcl package assumes that the source that is used to build Tcl is always kept around for compiling packages that depend on Tcl. These seds remove the reference to the build directory and replace them by saner system wide locations.

install ...: These commands install the internal headers into a system-wide location.

ln -sf ...: These commands create compatibility symbolic links.
