First, prevent the build process from installing XML files instead of man
|
|
pages:

</para>

|
|
<screen><userinput remap="pre">patch -Np1 -i ../giflib-&giflib-version;-upstream_fixes-1.patch</userinput></screen>
|
|
|
|
<para>
|
|
Next, remove an unnecessary dependency on <xref linkend="imagemagick"/>
|
|
by moving a file into an expected location:
|
|
</para>
|
|
|
|
<screen><userinput remap="pre">cp pic/gifgrid.gif doc/giflib-logo.gif</userinput></screen>

|
|
Install <application>giflib</application> by running the following
|
|
commands:

|
|
|
|
<screen><userinput>make</userinput></screen>
|
|
|
|
<!-- <para>

<para>
|

This package does not come with a test suite.
