    when building on Solaris 2.6 with gcc I get the following error:

    Let me add that I see -fPIC in the top-level Makefile but do not know
    why -static is not in the same variable as well. Anyway, it is not
    a shared library problem I think as I already recompiled my bzip2,
    openssl and ncurses libs with "-shared -fpic". ;-)

    Can you please report from the mmap man page how anonymous mappings can
    be achieved on Solaris 2.6?

    Thanks. None of the URLs seem to be helpful, anyway.
    Please avoid posting URLs without any indication as to what
    specific conclusion you like to see drawn from the page.

    It seems that Solaris 2.6 just doesn't have explicit support
    anonymous mmap explicitly. As a consequence, ctypes, in its
    current form, just can't run on it.

    A solution might be to map /dev/zero instead. Contributions
    are welcome.

    Thanks, but I can only help with testing. :(

    Here is a patch for Modules/_ctypes/malloc_closure.c that may work
    (totally untested). The code snippet is copied from Modules/mmapmodule.c.

    Corrected the patch.

    Issue bpo-5504 shows a possibly more future proof way to fix this issue.

    Should this be closed as won't fix? outofdate? superseded by 5504?
    Does it even apply to 2.7 or 3.x?

    2.5 is done with and no response to question about more recent versions.
