undefined external symbol 引用了外部的定义 extern int i; 可以通过查看该 Mach-O LoadCommand 中的 LC_DYSYMTAB 来获取三组 symbol 的偏移和大小 visibility 决定了 symbol definition 在 link 时对其他文件是否可见。上面说的 local symbol 对外不可见,global symbol 对外可见。 global symbol 里又分为两类:nor...
ld64 在 Resolve 阶段执行合并、处理 undefined 等操作都是基于该 SymbolTable 来完成。三、ld64 命令参数iOS 工程中一般不会主动触发 ld64,可以在 Xcode build log 中找到 linking 对应的 clang 命令,复制到 terminal 加上 -v 来输出 clang 调用的 ld 命令。
It was using system clang and lld, not devel/llvm* . The only other thing to have failed so far is multimedia/libpvx but it failed built both ways ( native and cross-build with /nxb-bin/. . . ). Do you have a log that would show the commands that were used to produce ...
