How to generate libpjsua2.so for x86 abi in jnilibs

I want to test the app with android 10 in emulator.So for that I only have "armeabi", "armeabi-v7a","arm64-v8a" in jnilibs. But running app with android 10 device(Emulator), requires x86 abi. So for that first I have downloaded ndk for x86.And the second thing is I want to generate libpjsua2.so for x86 abi.
I am using pjsip library.
I have referred to https://trac.pjsip.org/repos/wiki/Getting-Started/Android. What I have tried is,
1) Downloaded latest pjsip version and extracted in folder.
2) Followed the steps given in pjsip website as below,
$ cd /path/to/your/pjsip/dir
$ export ANDROID_NDK_ROOT=/path_to_android_ndk_dir
$ ./configure-android
$ make dep && make clean && make
$ cd /path/to/your/pjsip/dir
$ make clean
# cleanup pjsua sample app
$ cd pjsip-apps/src/pjsua/android/jni
$ make clean
# also cleanup pjsua2 sample app (SWIG)
$ cd /path/to/your/pjsip/dir
$ cd pjsip-apps/src/swig
$ make clean
$ cd pjsip-apps/src/swig
$ make clean
TARGET_ABI=x86 ./configure-android --use-ndk-cflags
Got error when reached above code,

checking build system type... x86_64-unknown-linux-gnu
checking host system type... Invalid configuration `llvm-linux-android': machine `llvm' not recognized
aconfigure: error: /bin/sh ./config.sub llvm-linux-android failed
In my pjsip2.7 folder I found a folder named llvm but that is a empty folder. I doesn't know What is that. I am using cent os 7. Why I am getting this error? What do I need to do to overcome this.

Try compile with this builder
replace in ./config.cong you are using 2.10
# PJSIP Version to download
PJSIP_VERSION=2.10
./prepare-build-system
and then
./build

ubuntu 15.10 64bit build Android source 5.0 version

How can I fix this problem？When I was building the Android source of 5.0 with
'make -j4', it was causing a problem.
This is the error log:

In my case, I get similar error when build Marshmallow 6.0.1_r1 in Ubuntu 18.04.
If you get similar errors like this:
build/core/binary.mk:646: recipe for target 'out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp' failed
make: *** [out/host/linux-x86/obj/EXECUTABLES/aidl_intermediates/aidl_language_l.cpp] Aborted (core dumped)
Look at the line carefully, it's a core dumped, so I use coredumpctl list, navigate to the end of list with G, then figure out the core dump executed path (right column) is prebuilts/misc/linux-x86/flex/flex-2.5.39
And the PREBUILT file shows:
xb#dnxb:~/my_android_src/prebuilts/misc/linux-x86/flex$ cat PREBUILT
The objects in this prebuilt directory can be rebuilt
using the source archive hosted at
http://sourceforge.net/projects/flex/files/
Commands:
./configure
make CFLAGS="-static" LDFLAGS="-static"
# (Disregard the errors at the end of the build)
rm flex
make CFLAGS="-static" LDFLAGS="-static" flex
# Copy the linker command line, replace it with static libm.a
gcc -static -static -o flex ccl.o dfa.o ecs.o scanflags.o gen.o main.o misc.o nfa.o parse.o scan.o skel.o sym.o tblcmp.o yylex.o options.o scanopt.o buf.o tables.o tables_shared.o filter.o regex.o /usr/lib/x86_64-linux-gnu/libm.a
xb#dnxb:~/my_android_src/prebuilts/misc/linux-x86/flex$
That's it, the first 2 lines said that you probably need to rebuild yourself if something went wrong since this flex-2.5.39 binary is prebuilt in another platform.
So simply untar the flex-2.5.39.tar.gz of this directory, go to the extracted flex-2.5.39 directory, then follows the PREBUILT instruction above.
In short, you need to do the following steps:
cd <ANDROID_TREE_DIR>/prebuilts/misc/linux-x86/flex
tar -zxvf flex-2.5.39.tar.gz
cd flex-2.5.39
make CFLAGS="-static" LDFLAGS="-static"
rm flex
make CFLAGS="-static" LDFLAGS="-static" flex
/bin/bash ./libtool --tag=CC --mode=link gcc -static -static -o flex ccl.o dfa.o ecs.o scanflags.o gen.o main.o misc.o nfa.o parse.o scan.o skel.o sym.o tblcmp.o yylex.o options.o scanopt.o buf.o tables.o tables_shared.o filter.o regex.o lib/libcompat.la /usr/lib/x86_64-linux-gnu/libm.a
cd ..
cp flex-2.5.39/flex .
mv flex flex-2.5.39

Linphone Compile on Windows 8

I am building Linphone application for android. I am working in Windows 8 64-Bit OS
I Followed the steps given in README file:
Download the Android ndk (>=r5c) from google.
Install the autotools: autoconf, automake, aclocal, libtoolize pkgconfig
Run the ./prepare_sources.sh script in the top level directory. This will download iLBC source files and convert some assembly files in VP8 project.
$ ./prepare_sources.sh
Finally from directory linphone-android, just execute command:
$ ${my google ndk directory}/ndk-build
then i get following error in Cygwin terminal:
$ ./prepare_sources.sh
./prepare_sources.sh: line 2: $'\r': command not found
./prepare_sources.sh: line 3: C:UsersNomsDesktoplinphone-android: command not found
./prepare_sources.sh: line 4: $'\r': command not found
./prepare_sources.sh: line 29: syntax error near unexpected token $'\r''
./prepare_sources.sh: line 29:cd $topdir/submodules/libilbc-rfc3951 && ./autog'n.sh && ./configure && make || ( echo "iLBC prepare stage failed" ; exit 1 )

Try to use mingw to compile it. I've built the library successfully. But not yet apk, cause some build error in myeclipse...

Build script for Android NDK in linux

How can I build my source for android with NDK.
Already I download ndk and I don't know how can I set arch compiler path.
This is my "build-for-android.sh" code:
#!/bin/sh
cairo=system
curl=system
pal=android
alsa=no
pulse=no
sles=yes
ffmpeg=yes
gallium=no
egl=yes
glx=no
PKG_CONFIG_PATH=$MOONLIGHT_PREFIX/lib/pkgconfig
if [ -d /usr/X11/share/aclocal ]; then
export ACLOCAL_FLAGS="-I /usr/X11/share/aclocal"
fi
./autogen.sh --host=arm-linux-androideabi --prefix=$MOONLIGHT_PREFIX --with-manual-mono=yes --with-testing=no --enable-browser-support --disable-desktop-support --with-unwind=no --with-ffmpeg=$ffmpeg --with-alsa=$alsa --with-pulseaudio=$pulse --with-opensles=$sles --with-pal=$pal --with-curl=$curl --with-cairo=$cairo --with-gallium-path=$gallium --enable-sdk=no --with-egl=$egl --with-glx=$glx CFLAGS="-DPLATFORM_ANDROID -I$MOONLIGHT_PREFIX/include $CFLAGS" LDFLAGS="-L$MOONLIGHT_PREFIX/lib $LDFLAGS" CXXFLAGS="-fno-rtti -DPLATFORM_ANDROID -I$MOONLIGHT_PREFIX/include $CFLAGS"
make $#
when I run it I get error below:

I can see them in ~/Android/android-ndk-r8b/toolchains/arm-linux-androideabi-4.4.3/prebuild/linux-x86/bin/* directory.

OK. I found it.:
First, a standalone toolchain is created to make the configure script easier to use
~$ android-ndk-r5b/build/tools/make-standalone-toolchain.sh --platform=android-8 --install-dir=android-8-toolchain
Next, the toolchain's bin directory is added to the PATH.
~$ export PATH=$PATH:~/android-8-toolchain/bin/

android ndk-build error on ubuntu 12.10 32 bit

i have downloaded the latest android ndk r8b on my ubuntu 12.10 beta 2 .
i have included the ndk directory in the PATH variable (when i write ndk-b in terminal and hit tab it auto-completes it) .
but when i try :
cd android-ndk/samples/san-angeles/jni
ndk-build
i get this error:
make: /home/mixpro/Android/android-ndk/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc: Command not found

make: *** [/home/mixpro/Android/android-ndk/samples/san-angeles/obj/local/armeabi/objs/sanangeles/importgl.o] Error 127
when checking the /android-ndk/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin directory using ls i get:

arm-linux-androideabi-cpp arm-linux-androideabi-gcov
arm-linux-androideabi-readelf arm-linux-androideabi-elfedit
arm-linux-androideabi-gdb arm-linux-androideabi-run
meaning there is no arm-linux-androideabi-gcc in the directory

I am afraid that somehow you got arm-linux-androideabi-addr2line arm-linux-androideabi-gcc deleted. On linux, it is just a symlink to arm-linux-androideabi-gcc-4.6.x-google, so it's very easy to restore it. But maybe, to be on the safe side, it's worthwhile to reinstall NDK.

you should create symbolic link like this : ln -s /usr/bin/arm-linux-gnueabi-gcc-4.7 "/home/sofien/Bureau/android-ndk-r8c/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/arm-linux-androideabi-gcc"
