FFmpeg fails to be built for android - android

I'm trying to build FFmpeg for android, everything works just fine until the build of build_android.sh, I get at the end :
/bin/sh: 1: cd: can't cd to ../ffmpeg-build/armeabi/lib
make: *** [install-libavresample-shared] Error 2
make: *** Waiting for unfinished jobs....
/bin/sh: 1: cd: can't cd to ../ffmpeg-build/armeabi/lib
make: *** [install-libavutil-shared] Error 2
/bin/sh: 1: cd: can't cd to ../ffmpeg-build/armeabi/lib
make: *** [install-libswresample-shared] Error 2
I've been inspecting this for a while but couldn't figure out where the problem is..
Any help will be very appreciated. Thank you.

I am on Ubuntu 18.04.2 LTS.
My autogen.input is:
--with-distro=LibreOfficeAndroid
--with-android-sdk=/home/bart/Android/Sdk
--with-android-ndk=/home/bart/Android/android-ndk-r20
--with-jdk-home=/usr/lib/jvm/java-8-openjdk-amd64
I have used this page as a manual.
Also, I have noticed that native-code.cxx file is empty in libreoffice/android/source
Ok, figured it out. I didn't had python2 installed on my system (however had python3). Could configure check it?

I have looked at the google groups and other stack overflow questions, but I cannot seem to figure out what is going wrong.

Well, ultimately after googling I discovered the AOSP for some reason did not support the latest version of Xcode tools and OS X. I dualbooted windows 7 with ubuntu, and did the whole process. And when I did the make command on ubuntu I typed: make -k -i -B. That is, I gave it the keep going, ignore make errors and build unconditionally flags.

Here is a solution if you're using Ubuntu:

or look for the lzop package of you OS.

Strip off the space in the directory name.
Try renaming "speech to text" to "speechtotext".

Building Pocketsphinx On Android on Windows

I have been following this Building Pocketsphinx on android for days now and I am very confused what to do now. I will be telling what I have done step by step so you will know what I have done wrong.
I am using Windows 7 64-bit.
First of all I have downloaded PocketSphinx and Sphinxbase and I have unpack it in C:\Sphinx. Then I have downloaded mingw from MINGW DOWNLOAD only that. after I downloaded this stuffs, I started the mingw.exe and as a amateur I am, I tried sudo -i only and that did not do anything so I gone to the next instructions installing swig.
I tried typing apt-get install swig and yum install swig as the same as last time it did not work. Then I have tried mingw-get install swig and the result is mingw-get.exe: *** ERROR *** swig: unknown package. So with that I tried again the next intructions installation of sphinxbase.
In installing sphinxbase, I have gone to sphinxbase directory - C:\Sphinx\sphinxbase and I typed ./autogen.sh. So with that it compiled without problems and I typed ./configure It compiled good as well. the next is make this is where I got a problem, it compiled but it got errors. the error is:
make[3]: *** [pio.lo] Error 1
make[3]: Leaving directory `/c/sphinx/sphinxbase/src/libsphinxbase/util`
make[2]: *** [All-recursive] Error 1
make[2]: Leaving directory `/c/sphinx/sphinxbase/src/libsphinxbase`
make[1]: *** [All-recursive] Error 1
make[1]: Leaving directory `/c/sphinx/sphinxbase/src`
make: *** [all-recursive] Error 1
this is the problem I got until now. Then I have tried downloading pio.lo from pio.lo download. So it fix the error but another error appeared. Second Error:
collect2.exe: error: ld returned 1 exit status
make[2]: *** [sphinx_fe.exe] Error 1
make[2]: Leaving directory `/c/sphinx/sphinxbase/src/sphinx_fe`
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/c/sphinx/sphinxbase/src`
make: *** [all-recursive] Error 1
This is where I got stuck. I have tried copying sphinx_fe from sphinxbase-0.7-win32.zip after doing that nothing happens. The compilation would only delete the sphinx_fe.exe.
My question is What Should I do now?
If it is not clear feel free to comment and ask. Thank you for the help.
MinGW is not supported for now, try to use Cygwin instead.
Actually you don't need to run autogen.sh and make, it's enough to unpack sources
sudo, yum and other commands are Unix only commands, you need to search for their analog on windows.
For more information about SWIG on windows see
