HarmonyOS 鸿蒙Next JNI找不到头文件

HarmonyOS 鸿蒙Next JNI找不到头文件

用 Native C++ 进行开发， 在 CMakeLists.txt 中添加了包含目录，但是编译报错。请问 DevEco 哪里可以设置编译 包含目录吗？

老哥你用是sdk几，为什么我的

老兄，我也是，请问你解决了吗，怎么解决的，

解决了，jni是java的，目前鸿蒙不支持了，只能用鸿蒙的make文件重新写，

包含 jni.h 的报错如何解决

具体步骤有吗？老兄。

这个报错具体怎么解决的，能分享一下吗？

target_link_libraries(entry libhilog_ndk.z.so liblua54.so)

target_link_libraries(entry libhilog_ndk.z.so lua54)

编译通过

针对“HarmonyOS 鸿蒙Next JNI找不到头文件”的问题，以下提供直接相关的解决方案：

在HarmonyOS（鸿蒙）系统中，如果在使用JNI（Java Native Interface）时遇到找不到头文件的问题，通常是因为环境配置或路径设置不正确。以下是一些可能的解决方法：

  1. 检查NDK路径：确保你的项目中正确配置了HarmonyOS的NDK路径。NDK包含了JNI所需的头文件和库文件。

  2. 更新或重新配置CMakeLists.txt：在你的CMake配置文件中，确保包含了正确的头文件搜索路径。例如，使用include_directories()函数来指定头文件所在的目录。

  3. 检查构建配置：在构建系统中（如DevEco Studio），检查你的构建配置是否指向了正确的NDK版本和路径。

  4. 环境变量：确保环境变量中包含了指向NDK的路径，这样编译器在查找头文件时能够正确定位。

  5. 清理和重建项目：有时候，简单的清理和重建项目可以解决路径或配置更新后未生效的问题。

如果以上方法均未能解决问题，可能是由于HarmonyOS版本更新导致的兼容性问题或其他未知原因。此时，建议直接联系官方客服以获取更专业的帮助。
