topic >>...when I call one ipp in Intel® Integrated Performance Primitives

Java JNI Can't find dependent libraries

I want to call ipp function via JNI. So I compiled dlls using c++ and I put these dlls into my Java project lib folder.

but when I call one ipp function jipp.core.ippGetCpuType(), it gives me error like:

Exception in thread "main" java.lang.UnsatisfiedLinkError: D:\DevelopJava\MyIPP\lib\jippcore.dll: Can't find dependent libraries
at java.lang.ClassLoader$NativeLibrary.load(Native Method)
at java.lang.ClassLoader.loadLibrary1(Unknown Source)
at java.lang.ClassLoader.loadLibrary0(Unknown Source)
at java.lang.ClassLoader.loadLibrary(Unknown Source)
at java.lang.Runtime.loadLibrary0(Unknown Source)
at java.lang.System.loadLibrary(Unknown Source)
at jipp.core.<clinit>(core.java:42)
at client.zero.main(zero.java:16)

but I already set java.library.path include intel path like:

\Program Files (x86)\Intel\Composer XE 2013\redist\intel64\ipp

D:\Program Files (x86)\Intel\Composer XE 2013\redist\intel64\compiler

so ,anyone can help me ?

Samuel,

Do you know which libraries you are linking too? That is, single-threaded or multi-threaded?

java->jipp.core.ippGetCpuType

java->jipp.core.ippGetCpuType()->JNI->ippcore-7.1.dll

sorry. I restart the compute

sorry. I restart the compute and test again. it's working. oh, eclipse is very bad.

Let you know results as soon as it is completed.
