Description:
------------
This bug is similar to https://bugs.php.net/bug.php?id=51706

But (^) it has been closed. The bug exists for fresh versions of PHP 5.6.25 & PHP 7.0.10

I tried to simply cross compile PHP with this :

./configure --host=arm-linux-androideabi --disable-all

Before doing the above, I set the environment variables :

export ARCH=arm
export TOOLCHAINROOT="/media/simsu/hello/Android/toolchain"
export PATH=$PATH:$TOOLCHAINROOT/bin/
export CC="arm-linux-androideabi-gcc --sysroot=$TOOLCHAINROOT/sysroot"
export CXX="arm-linux-androideabi-g++ --sysroot=$TOOLCHAINROOT/sysroot"

As you can see, I'm using the Android toolchain.

Expected result:
----------------
PHP should compile

Actual result:
--------------

struct HEADER and the other missing macros are supposed to be
declared in arpa/nameser_compat.h, which again is supposed to be
included from arpa/nameser.h. However, the Android SDK keeps
arpa/nameser.h intentionally blank[1].

I have some doubts that this is a good idea, and I don't know how
to solve this issue properly for PHP, but for a start you may try
to also include arpa/nameser_compat.h (see the attached patch
nameser_compat_hack).

I applied the patch. But the nameser_compat.h file is not found :

ext/standard/dns.c:51:33: fatal error: arpa/nameser_compat.h: No such file or directory

The Android toolchain doesn't have the nameser_compat.h header file[1]

Then, I'm afraid, we can't do much. :-(

Hey,
   I have decided to not compile using Android toolchain. I have successfully compiled PHP on arm with arm-linux-gnueabi.

One thing, while compiling with it I got an error :

sapi/phpdbg/phpdbg_prompt.o: In function `phpdbg_load_module_or_extension': sapi/phpdbg/phpdbg_prompt.c:1046: undefined reference to `DL_LOAD

It got fixed with this patch : https://patchwork.ozlabs.org/patch/657181/

Should I make a new bug report ?

Fine! So I'm marking this as documentation issue.

Yes, please.
