I'm on Fedora Linux 19, using the latest Android SDK, latest java SDK, and NDK=R9. Using the instructions here, I'm trying to create a python/kivy installation specialized for android, by running the command, ./distribute.sh -m "kivy". It produces the output below. Can anyone tell me what's going wrong here, and what I can do to fix it? Thank you.
./dist*sh -m "kivy"

In accordance with the above suggestion of downgrading the API and NDK (to 14 and r8c, respectively), I've downgraded the android tools, and the problem seems to have been resolved. Thanks!

I am building bzip2 1.0.6 without any issues, but I assume I'm not linking to it correctly or some other issue. Is there some sort of other architecture I'm supposed to be building?
This is the project I'm trying to build with
https://github.com/GRRedWings/python3-android
I'm trying to cross compile Python 3.7 for Android. I see in my output that bz2 if failing with the following error
The Bzip2 makefiles are not written for cross-compiles. They effectively ignore a user's flags like CFLAGS and LDFLAGS. The makefiles actually blows away a user's CFLAGS and sets it to CFLAGS=-Wall -Winline -O2 -g $(BIGFILES). Your flags like -target aarch64-none-linux-androideabi22 are not used.
There are two Makefiles in play. One is called Makefile and it builds the static library, if I recall correctly. The second is Makefile-libbz2_so, and it build the shared object. You need to fix the omissions and apply the fixes to both makefiles.
You should probably use a patched Bzip like bzip2-noloader. It honors a user's CFLAGS, CXXFLAGS, LDFLAGS, etc. The check-in of interest is Commit 34d170f31106.
The makefile recipes in bzip2-noloader look similar to the following. They preserve Seward's original settings in BZIP_CFLAGS. But they also utilize CPPFLAGS and allow a user override in CFLAGS. The override will pickup your flags like -target aarch64-none-linux-androideabi22.
blocksort.o: blocksort.c
$(CC) $(CPPFLAGS) $(BZIP_CFLAGS) $(CFLAGS) -c blocksort.c
Programs use LDFLAGS as expected:
bzip2: libbz2.a bzip2.o
$(CC) $(CPPFLAGS) $(BZIP_CFLAGS) $(CFLAGS) $(LDFLAGS) -o bzip2 bzip2.o -L. -lbz2
Finally, the bzip2-noloader fork also honor's PREFIX, DESTDIR, etc. So you can perform staged installs, too.
I am building bzip2 1.0.6 without any issues ...
You are probably building for i686 or x86_64, and not Aarch64. The problem does not surface until link time. You can use objdump to inspect the object files, if interested.
Also note the makefile does this:
CC=gcc
AR=ar
RANLIB=ranlib
LDFLAGS=
You may need to tweak those variable assignments, too. Sometimes ar and ranlib use unusual names, like ranlib-5.0. And also be sure the tools are on-path.
The way to write makefiles to avoid these sorts of problems is detailed at 7.2.3 Variables for Specifying Commands in the GNU Coding Standards. The short of it is, (1) leave CFLAGS (and friends) for the user; and (2) if a flag is needed, then always supply it.
The GNU Coding Standards uses this as an example:
CFLAGS = -g
ALL_CFLAGS = -I. $(CFLAGS)
.c.o:
$(CC) -c $(CPPFLAGS) $(ALL_CFLAGS) $<
Users can override the default CFLAGS of -g, and -I is always added because it is needed for the compile.
I am trying to build boost_1.60.0 (as shared library) for android with c++11 support. I am using the latest ndk (currently android-ndk-r10e). The build host is Windows-10.
This is for a non-opensource project. So as far as I understand I cannot use gnustl_shared, and I need to use c++_shared as the android c++ runtime.
my project-config.jam looks like this:
androidNDKRoot = c:/android-ndk-r10e ;

For brevity I've only build filesystem for this trial but in the end I plan to build at least thread, filesystem, date_time, asio and log libraries.
Finally the error I get is as follows.

The error tells that it needs the directory to find the necessary libraries, but the problem is that under android ndk there are several files with names rt and crtbegin_so.o and such. I guess I need to make the compiler determine the correct directory itself.
With all being said what I need actually is to build boost shared libraries for android with c++11 support. So I may accept your help either by pointing me in the right direction using the above build parameters or providing me a working sample so I can work out the details myself.
Oh also one more thing: if I use link=static instead of link=shared in the build command the build succeeds. But I have not tried the produced static libraries.
Building Boost on Linux using the NDK
I know you're asking about Windows, but I wanted to do this on macOS and it failed with nearly the exact error. I finally broke down and did it on my linode server it worked without a problem. This says to me that they aren't really doing a good job of testing other platforms. Compiling static only on macOS works as you also discovered on Windows.
Point of reference
NDK R13
Boost 1.62.0
Tested with clang++; g++ also works
If you're wondering why I'm using clang, the Release Notes have the following message:
GCC is no longer supported. It will not be removed from the NDK just
yet, but is no longer receiving backports. It cannot be removed until
after libc++ has become stable enough to be the default, as some parts
of gnustl are still incompatible with Clang. It will likely be removed
after that point.
user-config.jam
I placed this file in my home directory. Yuck.
androidNDKRoot = /path/to/ndk-R13-standalone ;

Modifying libtool.m4 in boost to avoid versioning of the libraries
libtool.m4 under tools/build/src/engine/boehm_gc/libtool.m4 in the boost source has no reference to android and you'll need to change version_type=linux in the section linux*) to version_type=none. This will cause symbolic links to appear without the version number appended to the end linked to the versioned shared libraries in the output.
Building
Target OS MUST be android to avoid the -lrt flag being passed which will cause shared linking to fail.
./b2 \
-d+2 \
-j 4 \
--reconfigure \
target-os=android \
toolset=clang-android \
include=${ANDROID_NDK_STANDALONE}/include/c++/4.9.x \
link=static,shared \
variant=debug,release \
threading=multi \
--layout=versioned \
--prefix=${BOOST_INSTALL_DIR} \
install
A relevant information is here (Boost for Android), where they have been able to successfully build the shared libraries, but it seems that the resulting files have a version suffix which android can't handle. Also one can't just rename the binary because the file name is hardcoded in it. One way out, as per the last post, is to set the variable version_type to none (version_type=none) in the linux section of file. In your case, the build setup could be a little different, but it may be worthwhile to take a look at the changes they made at that discussion.
user-config.jam
If you want to find boost from cmake(find_package) you must use the version of compiler, and not android like the top answer, in your user-config.jam like below according to boost doc.
androidNDKRoot = /path/to/ndk-R13-standalone ;

My answer for me in future. How to build latest Boost(1.79.0) with latest NDK(24.0) on Windows PC for Android.
Go to your downloaded boost_1_79_0 unpacked directory and build b2 tool:
.\bootstrap.bat
Check b2 tools is ready:
b2 --version
B2 4.8-git <-- possible output
create file user-config.jam in %HOME% directory with content like that(example):
using clang : arm64 : c\:/Users/l_chayka/Downloads/android-ndk-r24/toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android21-clang++.cmd : <cxxflags>-std=c++20 ;

using clang : x86 : c\:/Users/l_chayka/Downloads/android-ndk-r24/toolchains/llvm/prebuilt/windows-x86_64/bin/i686-linux-android21-clang++.cmd : <cxxflags>-std=c++20 ;
using clang : x86_64 : c\:/Users/l_chayka/Downloads/android-ndk-r24/toolchains/llvm/prebuilt/windows-x86_64/bin/x86_64-linux-android21-clang++.cmd : <cxxflags>-std=c++20 ;
Go to boost root and try to build for every Android architecture (arm, arm64, x86, x86_64) example:
c:\Users\l_chayka\Downloads\boost_1_79_0>b2.exe toolset=clang-x86_64 target-os=android link=static variant=debug threading=multi --layout=versioned --prefix=c:/boost-x64_86/ install
c:\Users\l_chayka\Downloads\boost_1_79_0>b2.exe toolset=clang-x86 target-os=android link=static variant=debug threading=multi --layout=versioned --prefix=c:/boost-x86/ install
c:\Users\l_chayka\Downloads\boost_1_79_0>b2.exe toolset=clang-arm target-os=android link=static variant=debug threading=multi --layout=versioned --prefix=c:/boost-arm/ install
c:\Users\l_chayka\Downloads\boost_1_79_0>b2.exe toolset=clang-arm64 target-os=android link=static variant=debug threading=multi --layout=versioned --prefix=c:/boost-arm64/ install
Now check you instalation prefix path.
I'm currently trying to compile the libtorrent source files with Python bindings for Android. To do this, I have my custom toolchain with a compiled Boost library.
I use the following command to configure the libtorrent installation:
./configure --host=$CROSSHOST --prefix=$CROSSHOME --with-boost=$CROSSHOME --with-boost-libdir=$CROSSHOME/lib --enable-static --disable-shared --enable-debug --enable-logging --enable-python-binding
The variables are setup as follow:
export ANDROIDNDK='/home/martijn/Documenten/android-ndk-r9d'
export SYSROOT=$ANDROIDNDK/platforms/android-14/arch-arm
export PYTHON=/home/martijn/Documenten/python-for-android/build/python/Python-2.7.2/hostpython
export PYTHON_CPP_FLAGS="-I/home/martijn/Documenten/python-for-android/build/python/Python-2.7.2 -I/home/martijn/Documenten/python-for-android/build/python/Python-2.7.2/Include"
# Custom ARM toolchain
export SYSROOT=$ANDROIDNDK/platforms/android-14/arch-arm
export PATH=/usr/local/gcc-4.8.0-arm-linux-androideabi/bin:$PATH
export CC=arm-linux-androideabi-gcc
export CXX=arm-linux-androideabi-g++
export CROSSHOST=arm-linux-androideabi
export CROSSHOME=/usr/local/gcc-4.8.0-arm-linux-androideabi
# Set ARM v5 architecture with debug flag!
export CFLAGS="-g"
export CXXFLAGS=$CLFAGS
Compiling without the --enable-python-binding flag gives no problem and I correctly get a libtorrent.so file. At the end of the compilation, I get the following error:

How to resolve it. I tried installing cython again but it did not helped.
It looks like your Cython is too old. I had similar issues when I started Kivy development on 12.04. Try installing a newer version from PPA or using PIP.
From PPA:
sudo apt-add-repository ppa:cython-dev/master-ppa
sudo apt-get update
sudo apt-get install cython
Using PIP:
sudo apt-get install python-pip
sudo pip install --upgrade cython
I am trying to cross-compile a very simple program for Android that worked with android-ndk-r6b and prior, but does not work on android-ndk-r7 and newer:
int main() {
;
return 0;
}
I was able to do so using an "agcc" script on an older version of Android that can be found here. I'm sincerely not trying to use an Android.mk file to build this. I know I can, but this is part of something much larger I'm working on. So take it for face-value that I am trying to cross-compile this in a different way.
Anyway, I try to build and get:
$ arm-eabi-gcc -o test test.c
/home/gnychis/Documents/android/os/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/../lib/gcc/arm-eabi/4.4.3/../../../../arm-eabi/bin/ld: warning: /tmp/cc00QD3x.o uses variable-size enums yet the output is to use 32-bit enums; use of enum values across objects may fail
/tmp/cc00QD3x.o:(.ARM.exidx.text.main+0x0): undefined reference to `__aeabi_unwind_cpp_pr0'
collect2: ld returned 1 exit status
So, the key error is the undefined reference to __aeabi_unwind_cpp_pr0.
After doing some digging, this symbol is in libgcc.a which I am linking to:
$ arm-eabi-nm /home/gnychis/Documents/android/os/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/lib/gcc/arm-eabi/4.4.3/libgcc.a | grep __aeabi_unwind_cpp_pr0

U __aeabi_unwind_cpp_pr0

It has a 'T' which tells me that it is in the code somewhere, right?
Here is the verbose output of arm-eabi-gcc which shows I am in fact linking to this library:

So I'm just a bit unsure why I am getting this undefined reference. I have used this same method of cross-compiling with a slightly different version of Android and had no issue.
Does anything stand out to anyone?

As you can see, your own object file (the temporary one) is the very last item on the command line. This is just wrong. It needs to be before the libraries, at least, if it is to link correctly.
Basically, your agcc script is passing -nostdlib (which says that you know better) and then passing the libraries manually, but doing it in completely the wrong order. If you fix this, all should be well.
Link order is very important. Objects and libraries that provide symbols must be linked after objects and libraries that require symbols.
There were certain versions of the tools that could tolerate bad ordering, but I think that was a bug, or mis-feature, because newer toolchains cannot, and should not. Presumably this script was written for one of those.
Where to find: __aeabi_unwind_cpp_pr0 and other mysterious, undefined functions
(I had a similar problem error to what you describe, but found a different solution, that may be helpful to you or others)
I found 'libgccunwind.a' library in the Google NDK package which defines a number of these mysterious functions (they are functions referenced by libc.a and other libraries in the NDK package, but not defined in a standard library) I found them defined in a libgccunwind.a library in:
\sources\android\gccunwind\libs\armeabi
NM shows that they are defined in that lib from an 'unwind-arm.o' file:
nm libgccunwind.a
unwind-arm.o:
U _GLOBAL_OFFSET_TABLE_
00000cf8 T _Unwind_Complete
00000cfc T _Unwind_DeleteException

000003c4 T _Unwind_VRS_Get
0000084c T _Unwind_VRS_Pop
00000430 T _Unwind_VRS_Set
00000844 T __aeabi_unwind_cpp_pr0
0000083c W __aeabi_unwind_cpp_pr1

w __cxa_begin_cleanup
w __cxa_call_unexpected
w __cxa_type_match
U __exidx_end
U __exidx_start
00000d1c T __gnu_Unwind_Backtrace
w __gnu_Unwind_Find_exidx
Independant of the libgccunwind.a above, I searched for __aeabi_unwind_cpp_pr0 and unwind-arm.c and unwind.c, and found various c source, for example:
http://lxr.free-electrons.com/source/arch/arm/kernel/unwind.c?a=arm
http://opensource.apple.com/source/gcc/gcc-5646/gcc/config/arm/unwind-arm.c
These programs seem to be derived from a similar source. My guess is that these 'unwind_cpp' (and related functions) are called by the functions in libc.a when a function returns or on certain events so that these functions can perform some debugging or tracing operation.
In any event, adding that directory in a -L linker option and -lgccunwind linker option (after the -lc linker option) allowed the linker to find those 'undefined' functions -- and let me get to the next problem I have in cross compiling to ARM systems.
