| 124 | <para> To run the tests for this package, valgrind requires a version of

[0134954] | 126 | Normally in LFS these debugging symbols are stripped at the end of

---|
| 127 | Chapter 6. To get this library, glibc must be rebuilt with the current
|
---|
| 128 | glibc version using the same compiler that was used to build LFS. The
|
---|
| 129 | ld-2.23.so can then be renamed to ld-2.23.so.dbg and copied to /lib.
|
---|
[f885719] | 130 | Then a symlink needs to be changed:</para>

[f885719] | 140 | Running the testsuite for this package can cause problems.
