Android Status

[Ignacious via Digitalmars-d-learn]

Well, I posed a reply but I guess it didn't get though ;/

I'm only suing android-x86 because I thought it would be easier 
to test/debug. My device is a cortex-arm7.

Two questions I have:

1. In the command lines present there is a lot of use of `x86`. I 
used them to compile the hello world for my device and it worked 
so I'm a bit confused. I realize there is the x86 binaries for 
compiling and then the binaries that are compiled to but not sure 
what is what.

2. I downloaded the native_app_glue.d and tried to compile it. It 
imports jni.d which I found in hello-jni and I copied that to the 
android folder and was able to compile it using effectively the 
same command line I used to compile the working hello world code.

but when I try to then use it to compile the hello-jni sample I 
get that it is an invalid format and many ELF relocation errors.

Could you send me your working native_app_glue.o(if for the 
cortex-arm7 or try to compile it for both cortex-arm7 and 
x86/x64) or explain to me what is the issue with linking it in 
and how to fix it?


cmdline that compiles android_native_app_glue.d
bin/ldc2 -m32 -shared  -Iandroid -c android_native_app_glue.d

(tried with -m64 and without either)

cmdline trying to compile hello-jni.

  $NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/clang 
-Wl,-soname,libhello-jni.so -shared 
--sysroot=$NDK/platforms/android-9/arch-x86 
../obj/local/x86/objs-debug/hello-jni/hello-jni.o 
../android_native_app_glue.o -lgcc  -gcc-toolchain  
$NDK/toolchains/x86-4.8/prebuilt/linux-x86 -target 
i686-none-linux-android -no-canonical-prefixes  
-Wl,--no-undefined -Wl,-z,noexecstack -Wl,-z,relro -Wl,-z,now  
-L$NDK/platforms/android-9/arch-x86/usr/lib -llog -landroid -lEGL 
-lGLESv1_CM -llog -lc -lm -fuse-ld=bfd 
-L../../../phobos/generated/linux/release/32 -l:libphobos2.a -o 
../libs/libhello-jni.so

which gives the errors

....
/usr/bin/ld.bfd: ../android_native_app_glue.o: Relocations in 
generic ELF (EM: 40)
/usr/bin/ld.bfd: ../android_native_app_glue.o: Relocations in

/usr/bin/ld.bfd: ../android_native_app_glue.o: Relocations in 
generic ELF (EM: 40)
../android_native_app_glue.o: error adding symbols: File in wrong 
format
clang: error: linker command failed with exit code 1 (use -v to 
see invocation)

It might be better to wait for you to finish your build setup 
which might resolve all these problems and be more robust(I'd 
like to be able to easily build for different platforms(for 
testing on VM and device). But if all I need to do is get the 
android_native_app_glue to work to run full fledged apps, then It 
seems I'm close? (just need to compile it to the correct format?)


Thanks for all the help!
