我正在尝试运行在Linux服务器上使用JNI并且应用程序崩溃的应用程序。
我收到以下崩溃报告（摘录）
# A fatal error has been detected by the Java Runtime Environment:

我在Mac上尝试了该应用程序并运行正常。但是，它在服务器上崩溃了。两台机器都使用Java 1.8 x64
我检查了日志并将问题缩小到以下命令：
Stack: [0x00007f96c7a14000,0x00007f96c7b15000], sp=0x00007f96c7b133b0, free space=1020k
Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code)
C [libc.so.6+0x67974] fwrite+0x34
我认为这与我的应用程序没有关系，因为它在我的机器上运行正常。有什么想法吗？

我将假设您已在Mac上编译，现在已部署在Linux服务器上。
与纯Java不同，JNI代码不会生成可移植的字节码。您必须为要定位的每个运行时环境生成二进制运行时。所以在这种情况下，无论你的服务器运行什么Linux版本，你都需要一个。
如果可以的话，最简单的事情可能就是在服务器上编译它。
