| 25 | |
---|
| 26 | <para>In multilib builds we install compilers and libraries for each available |
---|
| 27 | architecture. The description below says that perl installs several hundred |
---|
| 28 | libraries, but they are used by invoking <command>perl</command>, not by linking |
---|
| 29 | to them with <command>ld</command>. Although it is possible to install perl for |
---|
| 30 | 32 bits, move it to a different name, and then install the 64-bit version, it is |
---|
| 31 | almost always invoked as just <command>perl</command>. That means only the |
---|
| 32 | libraries and modules for the last version installed will be accessible. We |
---|
[a1a7bae] | 33 | therefore only install one version.</para> |
---|
[bf8c11f] | 34 | |
---|
| 35 | <para>Perl does not, by default, know about library directories with names other |
---|
| 36 | than lib, such as lib64. The following patch will allow it to install to lib64.</para> |
---|
| 37 | |
---|
| 38 | <screen><userinput>patch -Np1 -i ../&perl-multilib-patch;</userinput></screen> |
---|
| 39 | |
---|
| 40 | <para>There is a further (possibly cosmetic) anomaly - if we install perl and |
---|
| 41 | then run <command>perl -V</command> it will claim that libc is in /lib. The |
---|
| 42 | following patch fixes this, but only takes effect when <command>make install |
---|
| 43 | </command> is run.</para> |
