| 135 | <para>A few unexpected failures cannot always be avoided. The GCC developers
|
|---|
| 136 | are usually aware of these issues, but have not resolved them yet. In
|
|---|
| 137 | particular, the <filename class="libraryfile">libmudflap</filename> tests
|
|---|
| 138 | are known to be particularly problematic as a result of a bug in GCC
|
|---|
| 139 | (<ulink url="http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20003"/>).
|
|---|
| 140 | Unless the test results are vastly different from those at the above URL,
|
|---|
| 141 | it is safe to continue.</para>

|
|---|
| 147 | <para>Some packages expect the C preprocessor to be installed in the
|
|---|
| 148 | <filename class="directory">/lib</filename> directory.
|
|---|
| 149 | To support those packages, create this symlink:</para>
|
|---|
| 150 |
|
|---|
| 151 | <screen><userinput remap="install">ln -sv ../usr/bin/cpp /lib</userinput></screen>
|
|---|
| 152 |
|
|---|
| 153 | <para>Many packages use the name <command>cc</command> to call the C
|
|---|
| 154 | compiler. To satisfy those packages, create a symlink:</para>

|

| 157 |
|
|---|
| 158 | <para>Now that our final toolchain is in place, it is important to again ensure
|
|---|
| 159 | that compiling and linking will work as expected. We do this by performing
|
|---|
| 160 | the same sanity checks as we did earlier in the chapter:</para>
