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
ls -la

Now try to do make <module> -j4 again, no longer abort on such error.
p/s: Alternative way will be LANG=C make pm -j4 if you see something like LC_* error message.

Building PJSIP: "Make dep" command giving error on Windows7

I have followed all the steps written in the pjsip-startup guide.
But the last step (make dep && make clean && make) is giving me the following errors. I am on Windows 7.

Can someone help me to resolve these errors? Thanks!

After some research I come to know that don't use WINDOWS for building the PJSIP v2.x version. Now I am going to install Ubuntu on my system.
The build system is known to work on the following hosts:
Linux, many types of distributions.
MacOS X 10.2 mingw (Win2K, XP)
FreeBSD (must use gmake instead of make)
Building Win32 applications with Cygwin is currently not supported by the autoconf script (there are some conflicts with Windows headers), but one can still use the old configure script by calling ./configure-legacy. More over, cross-compilations might also work with Cygwin using this build system.
See the link for details.

Android build Error on OSX 10.8.5: cp: the -R and -r options may not be specified together

I'm trying to compile Android FS, on OSX 10.8.5, and I'm getting an error that seems related to the fact that the build is being done on OSX.
I did all the brew installations and the compilation is being done on a case-sensitive FS,
yet I'm getting the following:
target arm C++: libwebrtc_apm <= out/target/product/generic/obj/STATIC_LIBRARIES/libwebrtc_apm_intermediates/proto/external/webrtc/src/modules/audio_processing/test/unittest.pb.cc

make: * Deleting file `out/target/product/generic/system/vendor/lib/libbltsville_ticpu.so'
make: * Waiting for unfinished jobs....
Any ideas?
I know that -R can solve this issue, but the build is being done by scripts and it'll be very hard to change all the spots where -avr will be -avR!!
I'm looking for a way to replace the cp command to a more linux like command....

So I got an answer for this conundrum:
The Makefile & main.mk located in build/core
Are the rogue files that made the trouble, hope this'll help someone.

errors while building the android source code

I am trying to build the android source code in ubuntu 13.10, but I got so many errors
I have solved some of them then I got stucked . Now I want your help to build the android source code,
before to that I will tell my system specification :
I am using Pentium D machine with 4 GB RAM with 50 GB free space in hard drive
using ubuntu 13.10 which is of 64 bit OS
And what are the packages I have installed
Python 2.7.5+, GNU Make 3.81, java version "1.6.0_45"
And I have followed the procedure for build such as :
G41M-Combo:~/bin/source $ : source build/envsetup.sh
G41M-Combo:~/bin/source $ : lunch
G41M-Combo:~/bin/source $ : 13
G41M-Combo:~/bin/source $ : make -j3
in 4th step i am using pentium D machine it is of 2 core so i have tried make -j2 also
but i did not got much difference
i am attaching the errors which i got
No private recovery resources for TARGET_DEVICE manta

your help will be greatly appretiated to me
Thanks in advance

Never noticed about version of required compiler gcc for old androids from articles' google, so you must have installed gcc-4.4 and g++-4.4, g++-4.4-multilib, zlib1g-dev, openjdk-6-jre
After installed those, so then type export CC="/usr/bin/gcc-4.4" and CXX="/usr/bin/g++-4.4", and make sure to use version of java 6 by typing
update-alternatives --config java
update-alternatives --config javac
update-alternatives --config jar
Have fun for compiling.

You need C/C++ compiler for this to work, as I understand from error messages. Try this:
sudo apt-get install build-essential g++

compilation of VLC for Android fail

I'm trying to compile vlc using the following instructions http://wiki.videolan.org/AndroidCompile.
i get the vlc source using git but when i'm doing the next command:

Given prior Linux CLI experience, the best I can tell you is that it doesn't look like your tool-chain is fully initialized and needs some setup. Below is a link that documents initialization for a MAC build environment:
http://source.android.com/source/initializing.html

You probably should have set your NDK installation properly.
Download the latest Android NDK.
Unzip and move the extracted “android-ndk-r6″ directory to “/Applications”, so you end up with “/Applications/android-ndk-r6″.
Edit “~/.profile” to add the following:
export ANDROID_NDK=/Applications/android-ndk-r5b
export PATH=$PATH:$ANDROID_NDK:$ANDROID_NDK/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86/bin
The PATH was the key to solve this kind of problem to me. Because it makes possible to find and use "arm-linux-androideabi-gcc".
Refer to this web site.
