errors in dns.c while compiling PHP #1

ClosetGeek-Git · 2017-02-07T19:01:25Z

Compiling using Ubuntu and new NDK. Complaining about unrecognized vars/functions (HEAD, TX, etc). I get this issue every way that I try compiling PHP for Android and I know that it's due to how NDK/Bionic handles DNS compared to glibc but was hoping your build process would fix the issue. Am I doing something wrong? let me know if your not familiar with this issue and I'll post a copy of the result compiler.

Read this : https://github.com/LobbyOS/android-standalone/blob/master/compile/php/README.md

It has the solution to the dns.c problem

Includes seem to be defined between line 23 and line 119 in current ext/standard/dns.c. I'm assuming #undef HAVE_RES_NSEARCH on line 120 should work?

I added it here after including dns.h : https://github.com/php/php-src/blob/master/ext/standard/dns.c#L59

Still not working for some reason. Here's the outcome

Testing on a fresh install of Ubuntu Server 16.04.1 LTS. Fresh copy of android-ndk-r13b-linux-x86_64, fresh copy of php-7.1.1. Not building with any extensions at this time, just vanilla PHP with --disable-all to minimize complications. Here's the modifications that I've done to auto-compile.sh to remove fluff for now:


set -e

compileDir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

function setenv(){
  . $compileDir/setenv.sh
}

function php(){
  cd $compileDir/php/src

  . $compileDir/setenv.sh

  export CFLAGS="$CFLAGS -pie -fPIE -fpic -fPIC -ldl -lc -lsupc++ -lstdc++ -lstlport_static"
  
  ./configure --host=$TARGET \
    --disable-all \
    --with-pic \
    --with-config-file-path=php.ini --with-config-file-scan-dir=. \
    --enable-cli --disable-cgi \
    --prefix="$(`echo realpath '../output'`)"

  sed -i -e 's~-I/usr/include~-I${SYSROOT}/usr/include~g' Makefile
  sed -i -e 's~-L/usr/lib/i386-linux-gnu~-L${SYSROOT}/usr/lib~g' Makefile

  make clean
  make
  make install

  cd ..

  mkdir -p php php/extensions
  cp ./output/bin/php ./php/php-cli
  cp ./php-wrapper ./php/php

  chrpath --delete php/php-cli php/extensions/*

  mkdir -p php-22
  cp ./php/* ./php-22 -r
  ../android-elf-cleaner/output/aec ./php-22/php-cli ./php-22/extensions/*
}

if [ -z $1 ]; then
  php
else
  $1
fi

Also, I noticed that setenv.sh has includes for crystax. Are you using Google's Android NDK or CrystaX NDK?

Thanks

subins2000 · 2017-02-10T11:44:29Z

Move the #undef statement to different places and try. Try using Crystax maybe ?
I first used Google NDK and it compiled. Then I used Crystax.

ClosetGeek-Git · 2017-02-12T10:54:31Z

Nope, not working. I've spent around 30 hours trying to get this to build to the same result. Please let me know if there is more information that I can give you to help resolve this. What Linux distro are you using to successfully compile this? What NDK version? Can you post a copy of the PHP Makefile from the php/SRC dir of your working build tree, and a copy of the working dns.c file that you use? It has to be something simple, but I'm at a loss at this point.

subins2000 · 2017-02-13T04:41:13Z

I understand the frustation. I also spent more than 30 hours for compiling PHP.

My dns.c file
Output of uname -a : Linux simsu-veriton-series 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:06:14 UTC 2016 i686 athlon i686 GNU/Linux

I'm using Xubuntu 16.04 (32 bit)
NDK : crystax-ndk-10.3.2
