我不知道為什么會出現 UnsatisfiedLinkError

Question

我無法找到我的代碼返回 UnsatisfiedLinkError 的原因。

java.lang.UnsatisfiedLinkError: 'void fr.bastoup.spigotplusplus.link.CPPLink.loadPlugin(java.lang.String)'

但是 my.so 文件已正確生成並且似乎已加載，因為我嘗試加載它時沒有錯誤。

$ nm -DC native/Linux/x86_64/cpplink.so

                 w __cxa_finalize

我搜索了一個多月的答案，我不知道。 如果有人知道，那就太好了！

這是 github 回購： https://github.com/BastouP411/SpigotPlusPlus

謝謝 ！

好的，我剛剛忘記在 my.cpp 中包含我的 header 文件。 現在解決了！
