잘못된 ELF 클래스 : ELFCLASS32 (가능한 원인 : 아키텍처 단어 폭 불일치)

Question

잘못된 ELF 클래스를 말하는데 이상한 예외가 있지만 래퍼가 올바르게 설정되었습니다. http://eid.belgium.be/en/binaries/beid-sdk-3.5.3-ubuntu-9.10-i686-6193_tcm147-94066_tcm406-114986.tgz

Answer 1

자바의 64 비트 버전을 사용하고 있기 때문에 그것은 작동하지 않습니다, 당신이 사용하려는 SDK는 32 비트 네이티브 라이브러리 (libbeidlibJava_Wrapper.so.3.5.3)를 포함 . 64 비트 JRE는 32 비트 기본 라이브러리를로드 할 수 없습니다.

Java의 32 비트 버전을 사용하거나 64 비트 기본 라이브러리가있는 SDK 버전을 찾아야합니다.
