如何管理共享库中未定义的符号

Question

我有一个共享库，其中有未定义的符号

JNI_CREATEJavaVM

有什么方法可以包含外部依赖项或告诉编译器忽略该符号？

Answer 1

是的，您可以告诉编译器忽略该符号。

从man ld，

--unresolved-symbols=方法

确定如何处理未解析的符号。method 有四个可能的值：

   ignore-all
       Do not report any unresolved symbols.

   report-all
       Report all unresolved symbols.  This is the default.

   ignore-in-object-files
       Report unresolved symbols that are contained in shared
       libraries, but ignore them if they come from regular object files.

   ignore-in-shared-libs
       Report unresolved symbols that come from regular object
       files, but ignore them if they come from shared libraries.
