我知道它与链接依赖项有关，但我不知道如何修复它，我已经尝试修复这个问题好几个星期了，但没有成功。
app/gradle.build
cmake {
arguments "-DCMAKE_BUILD_TYPE=Release"
cppFlags "-std=c++17", "-v"
abiFilters "x86_64"
}
编辑：更新堆栈跟踪和CMakeLists.txt
从您的构建输出来看，某些 valhalla 库似乎相互依赖，而这些依赖性并未反映在您的 CMakeLists.txt 中。例如，Tyr 库似乎至少依赖于 Baldr、Loki、Thor 和 Odin 库（从你得到的未定义符号的名称可以看出）。为了反映这种依赖性，您应该在 CMakeLists.txt 文件中添加如下内容：
target_link_libraries(valhalla-tyr PUBLIC
valhalla-baldr
valhalla-loki
valhalla-thor
valhalla-odin
)
如果在应用此后您从其他库中获得未定义的符号，您还应该为其他 Valhalla 库添加类似的依赖项。
因此，链接器将传递一组略有不同的参数，一些库可能列出不止一次或以不同的顺序列出。这将帮助链接器找到丢失的符号。
另一种可能的解决方案是在最后一个 target_link_libraries 语句的 --start-group/--end-group 个参数中包含 Valhalla 库。此解决方案将更依赖于编译器，但如果此 CMakeLists 文件仅用于 Android，则可能没问题：
target_link_libraries( react-native
-Wl,--start-group
libvalhalla
valhalla-baldr
# other valhalla libraries
-Wl,--end-group
# ...
)

我知道它与链接依赖项有关，但我不知道如何修复它，我已经尝试修复这个问题好几个星期了，但没有成功。
app/gradle.build

cppFlags "-std=c++17", "-v"
abiFilters "x86_64"
}
编辑：更新堆栈跟踪和CMakeLists.txt
从您的构建输出来看，某些 valhalla 库似乎相互依赖，而这些依赖性并未反映在您的 CMakeLists.txt 中。例如，Tyr 库似乎至少依赖于 Baldr、Loki、Thor 和 Odin 库（从你得到的未定义符号的名称可以看出）。为了反映这种依赖性，您应该在 CMakeLists.txt 文件中添加如下内容：
target_link_libraries(valhalla-tyr PUBLIC
valhalla-baldr
valhalla-loki
valhalla-thor
valhalla-odin
)
如果在应用此后您从其他库中获得未定义的符号，您还应该为其他 Valhalla 库添加类似的依赖项。
因此，链接器将传递一组略有不同的参数，一些库可能列出不止一次或以不同的顺序列出。这将帮助链接器找到丢失的符号。
另一种可能的解决方案是在最后一个 target_link_libraries 语句的 --start-group/--end-group 个参数中包含 Valhalla 库。此解决方案将更依赖于编译器，但如果此 CMakeLists 文件仅用于 Android，则可能没问题：
target_link_libraries( react-native
-Wl,--start-group
libvalhalla
valhalla-baldr
# other valhalla libraries
-Wl,--end-group
# ...
)
