5.11.5. Installation of Tcl

This package and the next two are only installed to be able to run the test suites for GCC and Binutils. Installing three packages just for testing purposes may seem like overkill, but it is very reassuring, if not essential, to know that our most important tools are working properly.

Prepare Tcl for compilation:

cd unix
./configure --prefix=/tools

Build the package:

make

This package has a test suite available which can perform a number of checks to ensure it built correctly. However, the Tcl test suite in this chapter is known to experience failures under certain host conditions that are not fully understood. Therefore, test suite failures here are not surprising, but are not considered critical. Should you choose to run the test suite, the following command will do so:

TZ=UTC make test

The meaning of the make parameter:

Sometimes, package test suites will give false failures. You can consult the LFS Wiki at http://wiki.linuxfromscratch.org/ to verify that these failures are normal. This applies to all tests throughout the book.

Install the package:

make install

Important

Do not remove the tcl8.4.4 source directory yet, as the next package will need its internal headers.

Make a necessary symbolic link:

ln -s tclsh8.4 /tools/bin/tclsh
