openharmony3.0源码中头文件是怎样引用的？

问答对人有帮助，内容完整，我也想知道答案 0 我在code-3.0源码上编译oled例程时发现，build.gn中include头文件路径并不正确，但是能够编译成功，后来我干脆把include包含的头文件路径全删了，编译还是能够成功。我又在code-1.0源码上尝试同样的操作，编译报错。 openharmony源码中头文件是怎样引用的，问啥在code-3.0中删除了build.gn中的头文件也能正常编译？ 0

答案对人有帮助，有参考价值 0 搞清楚了，在code-3.0中由config.gni为开发板编译相关的配置，编译时会采用该配置文件中的参数编译所有OS组件，编译阶段系统全局可见。在config.gni中包含了很多头文件，常用的基本包含在内了，如下所示： # Board related headfiles search path. board_include_dirs = [ "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/system/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/config", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/config/nv", "${ohos_root_path}utils/native/lite/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/hi3861_adapter/kal/cmsis", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/kernel/base/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/targets/hi3861v100/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/kernel/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/arch/risc-v/rv32im", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/lib/libm/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/lib/libsec/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/net/wpa_supplicant-2.7/src/common", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/targets/hi3861v100/plat/riscv", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/kernel/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/kernel/extended/runstop", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/posix/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/linux/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/third_party/lwip_sack/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/lib/libc/musl/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/lib/libc/musl/arch/generic", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/lib/libc/musl/arch/riscv32", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/lib/libc/hw/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/lib/libc/nuttx/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/lib/libsec/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/targets/hi3861v100/config", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/targets/hi3861v100/user", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/targets/hi3861v100/plat", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/targets/hi3861v100/extend/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/arch", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/components/lib/libc/bionic/libm", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/shell/include", "${ohos_root_path}device/hisilicon/hispark_pegasus/sdk_liteos/platform/os/Huawei_LiteOS/net/telnet/include", ]
