| 18 | <para>Now is an appropriate time to verify that your pseudo terminals (PTYs) are
|
---|
| 19 | working properly inside the chroot environment. We will again quickly check that
|
---|
| 20 | everything is set up correctly by performing a simple test:</para>
|
---|
| 21 |
|
---|
| 22 | <screen><userinput>expect -c "spawn ls"</userinput></screen>
|
---|
| 23 |
|
---|
| 24 | <para>If you receive the message:</para>
|
---|
| 25 |
|
---|
| 26 | <blockquote><screen>The system has no more ptys. Ask your system administrator to create more.</screen></blockquote>
|
---|
| 27 |
|
---|
| 28 | <para>Your chroot environment is not set up for proper PTY operation. In this
|
---|
| 29 | case there is no point in running the test suites for Binutils and GCC until you
|
---|
[3be4d97] | 30 | are able to resolve the issue. Please refer back to <xref linkend="ch-system-proc"/>
|
---|
| 31 | and the <xref linkend="ch-system-MAKEDEV"/> section and perform the recommended steps
|
---|
[d0a6c4c] | 32 | to fix the problem.</para>
|

[73aedd1d] | 33 |
|
---|
| 34 | <para>This package is known to behave badly when you have changed its
|
---|
| 35 | default optimization flags (including the -march and -mcpu options).
|
---|
| 36 | Therefore, if you have defined any environment variables that override
|
---|
| 37 | default optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting
|
---|
| 38 | or modifying them when building Binutils.</para>
|
---|
| 39 |
|
---|
| 40 | <para>The Binutils documentation recommends building Binutils outside of the
|
---|
| 41 | source directory in a dedicated build directory:</para>
|
---|
| 42 |
|
---|
| 43 | <screen><userinput>mkdir ../binutils-build
|
---|
| 44 | cd ../binutils-build</userinput></screen>
|
---|
| 45 |
|
---|
| 46 | <para>Now prepare Binutils for compilation:</para>
|
---|
| 47 |
|
---|
[c288d97] | 48 | <screen><userinput>../&binutils-dir;/configure --prefix=/usr --enable-shared</userinput></screen>

[73aedd1d] | 49 |

| 50 | <para>Compile the package:</para>
|
---|

|
---|
| 52 | <screen><userinput>make tooldir=/usr</userinput></screen>
|
---|
| 53 |
|
---|
| 54 | <para>Normally, the <emphasis>tooldir</emphasis> (the directory where the
|
---|
| 55 | executables end up) is set to $(exec_prefix)/$(target_alias), which expands
|
---|
| 56 | into, for example, <filename>/usr/i686-pc-linux-gnu</filename>. Since we only
|
---|
| 57 | build for our own system, we don't need this target specific directory in
|
---|
| 58 | <filename>/usr</filename>. That setup would be used if the system was used to
|
---|
| 59 | cross-compile (for example compiling a package on an Intel machine that
|
---|
| 60 | generates code that can be executed on PowerPC machines).</para>

[90afe40d] | 62 | <important><para>The test suite for Binutils in this section is considered

[3be4d97] | 70 | <para>The test suite notes from <xref linkend="ch-tools-binutils-pass2"/> are still
