How build under android?

[galek]

Hi

I'm trying building in target for android under windows, using tegra-toolkit. how build it?

ndk-build returned "Could not find application project directory"

[galek]

I'm installed msys(using mingw-get), but i got what include files not found (string.h)

Hi,
there is a readme - how to build android in:
https://github.com/NVIDIAGameWorks/PhysX-3.4/blob/master/PhysX_3.4/readme_android.html
You need to copy required stuff into externals and then setup needed env variables in order to use compilation scripts in the Tools/android-dev.

Borous, thanks for reply.
All 3dparty-libs alredy copied. (+variant with fixed makefile for latest TDK)

Using Helpers result:

Nick@Nick-ПК /d/projects/ngtech/Development/Externals/physx/Tools/android-dev
$ physx-make
/d/projects/ngtech/Development/Externals/physx/Source/compiler/android16 /d/proj

Need a Config!

if directrly call from compiler directory:

Env-varibles:

export ANDROID_CONFIG=android16; export MAKE_THREADS=4; export JAVA_HOME=$PWD/../../externals/jdk

[AlesBorovicka]

You need to call it with config for example:
physx-make debug

[galek]

Borous, already.(physx-make release). Result is similiar:
not found <stdio.h>

[AlesBorovicka]

The stdio.h is expected to be in:
\Externals\android-ndk-r9d\toolchains\arm-linux-androideabi-4.8\prebuilt\windows\lib\gcc\arm-linux-androideabi\4.8\include-fixed\stdio.h

[galek]

Borous, yep, it's file exist

[AlesBorovicka]

Then you might have something locally defined that is breaking your build.
Please check:
https://github.com/NVIDIAGameWorks/PhysX-3.4/blob/master/PhysX_3.4/Source/compiler/android16/Makefile
https://github.com/NVIDIAGameWorks/PhysX-3.4/blob/master/PhysX_3.4/Source/compiler/android16/Makefile.PxFoundation.mk

[galek]

Don't know.
Installed:
Latest tegra-toolkit
Visual studio android kit
Mingw32 with msys

in any case thanks for reply

[AlesBorovicka]

You can try to compile it under linux by changing the NDK binary to linux:
NDK_BIN_DIR = ../../../../Externals/android-ndk-r9d/toolchains/arm-linux-androideabi-4.8/prebuilt/windows/bin

[galek]

For linux build(not android) - is successfuly.
but this makefile designed for windows

I will try
