> I've been having problems getting php-4.0.4 to compile on my linux system;
> the make keeps breaking when libphp.so is being linked with an undefined
> versioned symbol name __ns_name_unpack@@GLIBC_2.1 error.
>
> I've rebuilt and reinstalled glibc2.1.3, and every library I know of that
> php depends on, but that didn't solve the problem.
>
> I saw a post in the php bug database about the exact same problem
> which the
> poster solved by creating a shared version of libbind (which is not
> supported in the isc.org release of bind).
>
> This lead me to run objdump on both libbind.a and libresolv.so.2. Here's
> what I found:
>
> objdump -x /lib/libresolv.so.2 | grep __ns_name:
>
> 00004424 g F .text 0000011a __ns_name_unpack
> 00004044 g F .text 000001db __ns_name_ntop
>
> objdump -x /usr/lib/libbind.a | grep __ns_name:

> If I'm reading this correctly (I'm not experienced in programming under
> linux), this looks like both libresolv.so.2 (a shared library, part of
> glibc) and libbind.a (a static library, part of bind) are exporting
> __ns_name_unpack and __ns_name_ntop.
>
> Somehow, this does not strike me as a good thing for programs like php,
