PHP uses <literal>pkg-config</literal> to select the right library file, header files,
|
|
and compile flags to use for libxml2.
|
|
To ensure that the desired version of libxml2 is selected,
|
|
the <envar>PKG_CONFIG_PATH</envar> environment variable may
|
|
be used to control the search path for <literal>pkg-config</literal> prior to running the configure script:
|
|
<![CDATA[PKG_CONFIG_PATH="/path/to/libxml2/prefix/lib/pkgconfig:/lib/pkgconfig"]]>
