Question

Customer meets ?Library for Native Hostid Couldn't Be Loaded (-521,7024)? when running BasciExample in Java toolkit after enabling native hostid under Linux

# java BasicExample f4 1.0 license.lic
Exception in thread "main" java.lang.RuntimeException: Library for Native Hostid Couldn't Be Loaded (-521,7024)
at BasicExample.getVendorInfo(BasicExample.java:115)
at BasicExample.main(BasicExample.java:59)

Answer

1. Under Linux, check if path which contains liblmgr11.so is added into LD_LIBRARY_PATH
# echo $LD_LIBRARY_PATH

2. Verify if you are using same version of JDK as FNP C toolkit.
- If you are using 32-bit FNP C toolkit, make sure you installed 32-bit JDK
- If you are using 62-bit FNP C toolkit, make sure you installed 62-bit JDK

Additional Information

If you decompile flexlm.jar and open following source code
"C:\Program Files (x86)\FNP\FlexNet Licensing Toolkit for Java 11.12.0.0\java\flexlm\com\macrovision\flexlm\VendorInfo.class"
you should be able to find the exception is thrown by Java API System.loadLibrary(str2);
http://docs.oracle.com/javase/7/docs/api/java/lang/System.html#loadLibrary(java.lang.String)

I did some test and find the System.loadLibrary searchs liblmgr11.so in paths set into LD_LIBRARY_PATH.
