I have troubles to run the GStreamer tutorials. I followed all tutorial steps, and run into an error.
My System:

My System: Windows 10 - 64 bit

I tried:
Windows linkage problems : Due to problems related to the standard linker, Google’s Gold Linker is used to build GStreamer applications. Unfortunately, the Android NDK toolchain for Windows does not include the gold linker and the standard one has to be used.
If you observe linkage problems, you can replace the linker in your Android NDK with the gold one from this project. Download the android-ndk-r8b-ma-windows.7z file, extract \android-ndk-r8b\toolchains\arm-linux-androideabi-4.6\prebuilt\windows\arm-linux-androideabi\bin\ld.exe (only this file is needed) and overwrite the one in the same folder in your Android NDK installation.
No effect. Any ideas how to solve this?
I had similar problem before please give a try with ndk10b.It is always good to check in header files for __srget before move forward.

I don't have any idea about the error. I tried using google but i can't seem to find similar problems like mine.
The usual reason for this error is that you've compiled against android-23 or higher but are linking against something earlier. Another variation of that issue is when you have multiple libraries built against different API levels.
It looks like you are using a standalone toolchain? If that's correct, then I'd suspect your issue is either a prebuilt library that's part of libcurses (FWIR there aren't any of those, so unlikely) or that there's something funky going on in their build scripts that causes one of the two issues I mentioned. Tons of projects add their own Android specific hacks to their build scripts that always end up being the cause of these sorts of issues, so that wouldn't surprise me at all.
Should look at both the compilation command for tic.c and the link command for whatever library/executable is failing to link there. Make sure both are using the same API levels (look for things like $NDK/platforms/android-$API_LEVEL, -D__ANDROID_API__=$API_LEVEL, and -target arm-linux-androideabi$API_LEVEL).
btw, not ncurses 6, but I do have an example showing how to use standalone toolchains that had to build ncurses 5.9: https://github.com/DanAlbert/lua-ndk/blob/master/build_lua_with_libreadline.sh#L75. Might be worth taking a look to see if that helps at all.
I tried How to build and integrate OpenSSL into your Android NDK project – Scottyab's blog, but had problems with it:

I tried Compilation fails with android ndk r15b · Issue #3826 · openssl/openssl's comment, and it did remove one of the errors, but the others were left.
Compilation fails with android ndk r15b · Issue #3826 · openssl/openssl's comment has suggests using --deprecated-headers, didn't work either.
NDK: Unified Headers issue · Issue #445 · android-ndk/ndk's comment says it's resolved. I tried setting the CFLAGS=-D__ANDROID_API__=$API but it didn't help.
I also tried using clang as the compiler using and got
clang: error: unknown argument: '-mandroid'
Android Studio: clang error: unknown argument: '-mandroid''s answer has a good explanation for it.
Actually faisal00813/openssl_for_ios_and_android: OpenSSL Library for iOS and Android fork uses clang as the compiler and the -mandroid bug is resolved, but still getting the undefined reference to 'stdin'
I finally used willyliu/build-openssl-android: Builds openssl 1.1.0h with android ndk r17., and it worked great. My fork david-hoze/build-openssl-android: Builds openssl 1.1.0h with android ndk r17. has some minor fixes
I am trying to build the x86 image on AOSP 4.3 source code.
followed below steps:
source build/envsetup.sh
lunch ( selected aosp_x86-eng)
make -j4
It gives below error.
bionic/libc/include/string.h:219: error: undefined reference to '__strlen_chk'
bionic/libc/include/string.h:219: error: undefined reference to '__strlen_chk'
bionic/libc/include/string.h:219: error: undefined reference to '__strlen_chk'
bionic/libc/include/string.h:219: error: undefined reference to '__strlen_chk'
Question:
It the steps for building x86 in AOSP 4.3 is correct?
How we can fix the above error.
I've solved it when building libcurl. The key idea is setting D_FORTIFY_SOURCE=0 in flags to disable checks, as mentioned in the source code.
LOCAL_STATIC_LIBRARIES += libc
I am using https://github.com/lilac/Android-ImageMagick to build an ImageMagick library for Android. When trying to ndk-build ImageMagick I end up with the below errors.

The header file that defines the constants listed in the error is included jpeg.c
#include "jpeglib.h"
Any of you guys have an idea why I'm getting the undefined reference error?
The linker is not looking for "constants" it's looking for jump addresses to call functions. Your code obviously uses functions which are not available in the object code. This can have various reasons. Either you did not tell the compiler to use a library which is availabe or (in your case more likely) you did not tell the compiler that jpeg.c also needs to be compiled for this shared object. But this is difficult to diagnose without seeing the makefile.
Taking a short look at the ndk-modules folder of the git repository I get the feeling you need to build multiple modules. Maybe you just do it in the wrong order. Try building jpeg first.

I am using Windows with these tools:
eclipse Indigo.
android 2.2 sdk
android ndkbuild-r8b
swigwin-2.0.8
and this is my configuration on my eclipse:
SWIG:
Main: C:\swigwin-2.0.8\swig.exe
NDK-build:
Main:
C:\android-ndk-r8b\ndk-build.cmd
Try swig 1.3. There could be issues with 2.0. Check full build log for details.
pocketsphinx-0.7 is incompatible with the swig-2.0.8
