114 | <note><para>
|
---|
115 | To run the tests for this package, valgrind requires a version of the
|
---|
116 | /lib/ld-2.23.so (or later) library with debugging symbols present.
|
---|
117 | Normally in LFS these debugging symbols are stripped at the end of
|
---|
118 | Chapter 6. To get this library, glibc must be rebuilt with the current
|
---|
119 | glibc version using the same compiler that was used to build LFS. The
|
---|
120 | ld-2.23.so can then be renamed to ld-2.23.so.dbg and copied to /lib.
|
---|
121 | Then a symlink needs to be changed:</para>
|
---|
122 |
|
---|
123 | <screen><userinput>ln -sfv ld-2.23.so.dbg /lib/ld-linux-x86-64.so.2</userinput></screen>
|
---|
124 |

---|
125 | <para>Adjust the above instruction as needed for a 32-bit system

|

131 | Running the testsuite for this package can cause problems.
|
---|
132 | It creates a number of dummy input devices on the currently
|
---|
133 | running system that can lead to crashing a local X server or
|
---|
134 | a desktop environment. If you understand the risks and have
|
---|
135 | the optional <xref linkend="check"/> and
|
---|
136 | <xref linkend="valgrind"/> packages installed, the regression
|
---|
137 | tests can be run as the <systemitem

139 | <userinput>make check</userinput>. Note that depending on
