Why am I getting this Android Studio error: "recompile with -fPIC"?
Why am I getting this Android Studio error: "recompile with -fPIC"?
我正在使用 NDK 18 并使用 x86_64 NDK 独立工具链单独编译静态库。我可以 link 它成功但是当我尝试以一种非常重要的方式访问库时，我在构建时遇到了很多错误，比如：
... requires dynamic R_X86_64_PC32 reloc against '_ZZN4seal4util21get_msb_index_genericEPmmE15deBruijnTable64' which may overflow at runtime; recompile with -fPIC
有关我的构建文件的详细信息，请参阅我之前的问题：
按照此处的建议： 我确保使用 -fPIC 编译静态库（并使用 VERBOSE=1 的 CMake 确认使用了 -fPIC），但我仍然得到错误。据我所知，如果不侵入它的 CMake 文件，我无法将其编译为共享库。
这里有一些回答：How to recompile with -fPIC建议在编译器后面直接加上-fPIC。我也尝试过但没有成功。
编译静态库的示例输出（确认 cmake 正在使用 -fPIC）：
