    I wanted to have three libraries out of libxml2.a: libxml2.so,
    libxml2.so.2 and libxml2.so.2.6.20. Libxml2.so and libxml2.so.2 are
    symbolic links and libxml2.so.2.6.20 is the actual library. I renamed libxml2.a as libxml2.so, because I am not clear with the naming
    convention of .a files. That is, i don't know how to name the physical library and the symbolic links of .a libraries.
    If I rename libxml2.a as libxml2.so I face one problem. There is a
    software libxslt, which I am building from its source. It links with
    libxml2 library while building. But it is unable link with libxml2.so.
    But it links properly with libxml2.a


    Hi,
    I am trying to build the library as well. Can you please tell what are compiler flags/options you used?

    --enable-shared does not create a shared library for me

    --enable-shared is a Libtool flag passed to configure.
    By default on AIX, it will generate an AIX shared library - with a name like - libxml2.a
    AIX also has System V compatibility libraries, libFOO.so, to make Libtool generate those, you'll need to have '-brtl' in your linker flags when you configure.
    For C:
    LDFLAGS="-brtl"

    For C++:
    LDFLAGS="-Wl,-brtl"

    Libtool looks for the presence of this flag, and switches to creating a "libX.so" file instead
