Cannot compile library ndk-build

[saki4510t]

Hi,
Sorry my answer delayed.
As I can see you log, it seems to be build on Eclipse? and error Le fichier spécifié est introuvable. means specific file not found?
D:/android-ndk-r11c-windows-x86/android-ndk-r11c/build//../toolchains/arm-linux-androideabi-4.9/prebuilt/windows-x86_64/bin/arm-linux-androideabi-g++ etc. is correct path? I think duplicated slash after build will be wrong.
Is it possible to build using gradle or ndk-build from command line?

Hi Saki,
I am having this specified file not found error when compiling the library. Could you kindly help to resolve it?
I have followed the steps you have given for eclipse.
I am giving ndk-build from Windows command prompt. Android-NDK is r12.

Hi,
As I tested on my Windows 7(64bit) with r12(64bit), my repositories can build and works well.
I also tested on my Windows 7(64bit) with r12(32bit), it generated same error as yours.

So I assume you might install wrong version of NDK, ex. 64bit version on 32bit Windows or 32bit version on 64 bit Windows. Because the download link of latest NDK(r12) on Android Developers is wrong (reversed).

It looks like this;

Platform	Package	Size (Bytes)	SHA1 Checksum
Windows 32-bit	android-ndk-r12-windows-x86_64.zip	749444245	...
Windows 64-bit	android-ndk-r12-windows-x86.zip	706332762	...
...	...	...	...

If you use 32bit Windows, you should download and install android-ndk-r12-windows-x86.zip and if you use 64bit Windows, you should download and install android-ndk-r12-windows-x86_64.zip

I don't have 32bit Windows now and I'm not sure r12(32bit) works on 32bit Windows though.

with best regards,
saki

Hi Saki,

Thanks a lot for your reply. Mine is 64bit Windows and It worked when i installed android-ndk-r12-windows-x86_64.zip. Actually in the Android NDK website the package names were wrongly mentioned for the 32bit and 64bit.

Regards,
Rashmi
