| 15 | <para>Now is an appropriate time to verify that your pseudo terminals (PTYs) are
|
---|
| 16 | working properly inside the chroot environment. We will again quickly check that
|
---|
| 17 | everything is set up correctly by performing a simple test:</para>
|
---|
| 18 |
|
---|
| 19 | <screen><userinput>expect -c "spawn ls"</userinput></screen>
|
---|
| 20 |
|
---|
| 21 | <para>If you receive the message:</para>
|
---|
| 22 |
|
---|
| 23 | <blockquote><screen>The system has no more ptys. Ask your system administrator to create more.</screen></blockquote>
|
---|
| 24 |
|
---|
| 25 | <para>Your chroot environment is not set up for proper PTY operation. In this
|
---|
| 26 | case there is no point in running the test suites for Binutils and GCC until you
|
---|
| 27 | are able to resolve the issue. Please refer back to <xref linkend="ch06-proc"/>
|
---|
| 28 | and <xref linkend="ch06-makedev"/> and perform the recommended steps to fix the
|
---|
| 29 | problem.</para>
|
---|
| 30 |
|
---|
| 31 | <note><para>The test suite for Binutils in this section is considered
|
---|
| 32 | <emphasis>critical</emphasis>. Our advice is to not skip it under any
|
---|
| 33 | circumstances.</para> </note>
|
---|
| 34 |
|
---|
| 35 | <para>This package is known to behave badly when you have changed its
|
---|
| 36 | default optimization flags (including the -march and -mcpu options).
|
---|
| 37 | Therefore, if you have defined any environment variables that override
|
---|
| 38 | default optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting
|
---|
| 39 | or modifying them when building Binutils.</para>
|
---|
| 40 |
|
---|
| 41 | <para>The Binutils documentation recommends building Binutils outside of the
|
---|
| 42 | source directory in a dedicated build directory:</para>
|
---|
| 43 |
|
---|
| 44 | <screen><userinput>mkdir ../binutils-build
|
---|
| 45 | cd ../binutils-build</userinput></screen>
|
---|
| 46 |
|
---|
| 47 | <para>Now prepare Binutils for compilation:</para>
|
---|
| 48 |
|
---|
| 49 | <screen><userinput>../binutils-&binutils-version;/configure \
|
---|
| 50 | --prefix=/usr --enable-shared</userinput></screen>
|
---|
| 51 |
|
---|
| 52 | <para>Compile the package:</para>
|
---|
| 53 |
|
---|
| 54 | <screen><userinput>make tooldir=/usr</userinput></screen>
|
---|
| 55 |
|
---|
| 56 | <para>Normally, the <emphasis>tooldir</emphasis> (the directory where the
|
---|
| 57 | executables end up) is set to $(exec_prefix)/$(target_alias), which expands
|
---|
| 58 | into, for example, <filename>/usr/i686-pc-linux-gnu</filename>. Since we only
|
---|
| 59 | build for our own system, we don't need this target specific directory in
|
---|
| 60 | <filename>/usr</filename>. That setup would be used if the system was used to
|
---|
| 61 | cross-compile (for example compiling a package on an Intel machine that
|
---|
| 62 | generates code that can be executed on PowerPC machines).</para>
|
---|
| 63 |
|
---|
| 64 | <para>Test the results:</para>
|
---|
| 65 |
|
---|
| 66 | <screen><userinput>make check</userinput></screen>
|
---|
| 67 |
|
---|
| 68 | <para>The test suite notes from <xref linkend="ch05-binutils-pass2"/> are still
|
---|
| 69 | very much appropriate here. Be sure to refer back there should you have any
|
---|
| 70 | doubts.</para>
|
---|
| 71 |
|
---|
| 72 | <para>Install the package:</para>
|
---|
| 73 |

---|

|

|
---|
| 76 | <para>Install the <emphasis>libiberty</emphasis> header file that is needed by
|
---|
| 77 | some packages:</para>
