8.4. Tcl-8.6.10

8.4.1. Installation of Tcl

This package and the next two (Expect and DejaGNU) are installed to support running the test suites for GCC and binutils and other packages. Installing three packages for testing purposes may seem excessive, but it is very reassuring, if not essential, to know that the most important tools are working properly. These packages are required to run the test suites in this chapter.

First, unpack the documentation by issuing the following command:

tar -xf ../tcl8.6.10-html.tar.gz --strip-components=1

Prepare Tcl for compilation:

SRCDIR=$(pwd)
cd unix
./configure --prefix=/usr           \
            --mandir=/usr/share/man \
            $([ "$(uname -m)" = x86_64 ] && echo --enable-64bit)

Build the package:

make

sed -e "s|$SRCDIR/unix|/usr/lib|" \
    -e "s|$SRCDIR|/usr/include|"  \
    -i tclConfig.sh

sed -e "s|$SRCDIR/unix/pkgs/tdbc1.1.1|/usr/lib/tdbc1.1.1|" \
    -e "s|$SRCDIR/pkgs/tdbc1.1.1/generic|/usr/include|"    \
    -e "s|$SRCDIR/pkgs/tdbc1.1.1/library|/usr/lib/tcl8.6|" \
    -e "s|$SRCDIR/pkgs/tdbc1.1.1|/usr/include|"            \
    -i pkgs/tdbc1.1.1/tdbcConfig.sh

sed -e "s|$SRCDIR/unix/pkgs/itcl4.2.0|/usr/lib/itcl4.2.0|" \
    -e "s|$SRCDIR/pkgs/itcl4.2.0/generic|/usr/include|"    \
    -e "s|$SRCDIR/pkgs/itcl4.2.0|/usr/include|"            \
    -i pkgs/itcl4.2.0/itclConfig.sh

unset SRCDIR

The various “sed” instructions after the “make” command removes references to the build directory from the configuration files and replaces them with the install directory. This is not mandatory for the remainder of LFS, but may be needed in case a package built later uses Tcl.

To test the results, issue:

make test

Install the package:

make install

Make the installed library writable so debugging symbols can be removed later:

chmod -v u+w /usr/lib/libtcl8.6.so

Install Tcl's headers. The next package, Expect, requires them.

make install-private-headers

Now make a necessary symbolic link:

ln -sfv tclsh8.6 /usr/bin/tclsh
