PJSIP Compilation is failing for MIPS as ABI with latest Android NDK toolchain

["Mehul Hirpara" <mehul.hirpara@xxxxxxxxxxxxxxxx>]

Hi All,

For me PJSIP compilation is failing for MIPS platform with following commands and with latest Android NDK tool-chain version 14.1.3816874.

Commands:

$export ANDROID_NDK_ROOT=/home/mehul/Android/Sdk/ndk-bundle
$export APP_PLATFORM=android-18
$NDK_TOOLCHAIN_VERSION=4.9 TARGET_ABI=mips ./configure-android --use-ndk-cflags
$make dep
$make clean
$make

Failure Log:

Analysis:

This failure is quit know and in most cases people suggested to provide correct system root path. In my case I found system root path is correct and is as below:

--sysroot=/home/mehul/Android/Sdk/ndk-bundle/platforms/android-18/arch-mips

crtbegin_dynamic.o and other files are present at

/home/mehul/Android/Sdk/ndk-bundle/platforms/android-18/arch-mips/usr/lib

but system is look it at

/home/mehul/Android/Sdk/ndk-bundle/toolchains/mips64el-linux-android-4.9/prebuilt/linux-x86_64/lib/gcc/mips64el-linux-android/4.9.x/

Not sure why?

Same is working for "armeabi" platform but not for "mips"

Workaround:

I changed my tool-chain to older one "android-ndk-r9" and all goes fine.

$export ANDROID_NDK_ROOT=/home/mehul/Android/Sdk/android-ndk-r9

$export APP_PLATFORM=android-18

$NDK_TOOLCHAIN_VERSION=4.8 TARGET_ABI=mips ./configure-android --use-ndk-cflags

$make dep
$make clean
$make

I do not want to rely on workaround if any fix is available. Please let me know if any one has encountered with similar issue and any fix is available.

Thanks in advance.

Mehul Hirpara
