Ok, so after building randomx submodule from sources and placing librandomx.so to parent proj solved issue Although, when importing lib as Maven dependency, issue is the same My question is how portable this solution? I don't have too much experience with C++ and JNI, so not sure if .jar file with included xdagj-native-randomx-0.1.7 Maven dependency will work (both on Linux and Windows)

Theoretically, xdagj-native-randomx can run on any platform where randomx can run. jna is just a call, which facilitates the verification of randomx integrated into java programs.
