NDK R10 32 bit builds

[LXS5461]

Hi all,

I am trying to use android-ndk64-r10-windows-x86 to build 32 bit android binaries on my windows machine.

The NDK command I use is - 

android-ndk64-r10-windows-x86\android-ndk-r10\ndk-build.cmd NDK_DEBUG=1 APP_PLATFORM=android-L -j8 NDK_TOOLCHAIN_VERSION=4.9 NDK_TOOLCHAIN=arm-linux-androideabi-4.9 APP_ABI=armeabi-v7a TARGET_BOARD_PLATFORM=<> TARGET_PRODUCT=<> PLATFORM_SDK_VERSION=L

However, when I build it, make errors out,

copy /b/y "C:\AndroidNDK\android-ndk64-r10-windows-x86\android-ndk-r10\prebuilt\android-arm\gdbserver\gdbserver" "libs\armeabi-v7a\gdbserver" > NUL

make.exe: *** [libs/armeabi-v7a/gdbserver] Error 1

make.exe: *** Waiting for unfinished jobs....

I see that, in AndroidNDK64-R10, prebuilt\android-arm\gdbserver\gdbserver is missing.

If I copy it from old NDK to prebuilt\android-arm\gdbserver, I seems to compile fine.  Is this a bug or something else is going on here?

Thanks for your inputs.

Any suggestions please ? 

Thanks!

ndk64 are meant to build 64bit binaries...

use ndk32 if you want to build 32bit binaries

Thanks Simons! It works fine with ndk32. Appreciate your help.

Hello Phillippe,

Can you explain me what is the difference in the 32-bit armeabi binaries compiled using ndk32 and ndk64?

Because in my project when I compile binary using ndk32, it runs fine; but when I compile 32-bit binary using ndk64, it says it can not load/find library.
Please note that compilation succedded but it could not load the library at run time.

Thanks for your help.
