Build native libraries:
|

|
|
||||||
|
* modify jni/builder/JniBuilder.java for your platform.
|
||||||
|
|
||||||
|
* get gdx-jnigen, then run:
|
||||||
|
|
||||||
|
javac -cp gdx-jnigen.jar jni/builder/JniBuilder.java
|
||||||
|
java -cp gdx-jnigen.jar:jni/builder JniBuilder
|
||||||
|
|
||||||
|
* to build android:
|
||||||
|
export NDK_HOME=/your_android_ndk_path
|
||||||
|
|
||||||
|
* compile
|
||||||
|
cd jni
|
||||||
|
ant -v
|
||||||
|
|
