fcmaes-java's Issues

The specified procedure could not be found

Thanks for making it available for java. But while testing on Windows 11 x64, the following errors were thrown:

DLL path was correctly set in PATH environment variable, and ProcMon utility showed that the java.exe process loaded the fcmaeslib.dll and its dependent DLLs successfully.

Build error when running the examples

Hi!

I am very interested in the Java version of fcmaes and I tried to run some examples provided in the repositories. However, whenever I run one of the files provided in the examples folder the build fails and no result is obtained.

I provide a screenshot of what happens when I digit the "mvn install" command. The outcome is "BUILD SUCCESS" but there are some warnings and exceptions arising from the tests.

mvn_tests mvn_warnings

I provide you more information about the operative system and so on:

  • OS: Ubuntu 22.04.03 LTS
  • OpenJDK 17.0.9
  • Apache Maven 3.6.3
  • Gradle 8.5

I thank you for you time and I hope that you can help me to solve the issue so that I can use your Java version of fcmaes.

Regards
