[Jepp-users] Success story: building jep on win64

[G. W. <Gue...@lc...>]

Hi Nathan,

Thank you for your tips! I really apprechiate your work!
After deleting all copies of jep.pyd a simple java test programm worked
fine!

import jep.Jep;
public class JepTest2 {

	public static void main(String[] args) throws Exception {

		 Jep jep = new Jep();
		 jep.set("x", 4);
		 jep.eval("a=2*x+5");
		 jep.runScript("f:\\test.py");
		 System.out.println(jep.getValue("c"));
		 jep.close();		
	}
}


But I was not able to the jep.bat; A C++ Runtime error appeared. See
the screenshot attached.
My java runtime is still located in the "program files" folder. Might
this be a problem?

The console output looks like this:

....
c:\Miniconda\DLLs\jep>java -classpath
c:\miniconda\lib\jep\jep-3.3.4.jar jep.Run
"c:\miniconda\Lib\site-packages\jep\console.py"

Any idea about the "1114 a dynamic link library (dll) initialization
routine failed" error?

Btw, later, I will post a summary of all the steps which  brought me to
a successful installation of jep 3.3.4 on win64.

Günther
