Installation of Tcl
This package is also installed in LFS during the bootstrap phase. As it is not installed during Chapter 6 of LFS, installation instructions are included here in BLFS.
If you downloaded the optional documentation, unpack the tarball by issuing the following command:
tar -xf ../tcl8.5.10-html.tar.gz --strip-components=1
Install Tcl by running the following commands:
cd unix && ./configure --prefix=/usr \ --enable-threads \ --mandir=/usr/share/man && make && sed -i \ -e "s@^\(TCL_SRC_DIR='\).*@\1/usr/include'@" \ -e "/TCL_B/s@='\(-L\)\?.*unix@='\1/usr/lib@" \ tclConfig.sh
To test the results, issue: make test.
Now, as the root user:
make install && make install-private-headers && ln -v -sf tclsh8.5 /usr/bin/tclsh && chmod -v 755 /usr/lib/libtcl8.5.so
If you downloaded the optional documentation, install it by issuing the following commands as the root user:
install -v -m755 -d /usr/share/doc/tcl-8.5.10 && cp -v -R ../html/* /usr/share/doc/tcl-8.5.10
Command Explanations
--enable-threads: This switch forces the package to build with thread support.
make install-private-headers: This command is used to install the Tcl library interface headers used by other packages if they link to the Tcl library.
ln -v -sf tclsh8.5 /usr/bin/tclsh: This command is used to create a compatibility symbolic link to the tclsh8.5 file as many packages expect a file named tclsh.
sed -i -e ... tclConfig.sh: The Tcl package expects that its source tree is preserved so that packages depending on it for their compilation can utilize it. This sedremoves the references to the build directory and replaces them with saner system-wide locations.
