[OpenHarmony] 记一次 LiteOS-M 移植编译报错解决：PRId64 未定义与类型转换警告

在进行 OpenHarmony（LiteOS-M 内核）涉及 ARM Cortex-M4 芯片（如 HC32F467）的移植开发过程中，我们经常会遇到因为工具链差异或编译器版本过高导致的编译错误。本文记录了两个典型的报错案例及其“零代码侵入”的修复方案。

环境背景

• 系统：OpenHarmony (LiteOS-M)
• 目标芯片：HC32F467 (Cortex-M4)
• 编译器：arm-none-eabi-gcc
• 涉及模块：device_auth (设备认证子系统)

问题一：PRId64 未定义报错

1. 报错现象

在编译 base/security/device_auth 模块时，出现如下错误：

[OHOS ERROR] ../../../base/security/device_auth/common_lib/impl/src/json_utils.c: In function 'AddInt64StringToJson':
[OHOS ERROR] ../../../base/security/device_auth/common_lib/impl/src/json_utils.c:498:46: error: expected ')' before 'PRId64'
[OHOS ERROR]   498 |     if (sprintf_s(buffer, sizeof(buffer), "%" PRId64, value) <= 0) {

[OHOS ERROR]

2. 原因分析

• 交叉编译环境差异：虽然宿主机（Linux）的 /usr/include 下有 inttypes.h，但交叉编译器（arm-none-eabi-gcc）使用的是自己的 Sysroot（通常是 Newlib）。
• 标准库裁剪：嵌入式环境下的 Newlib C 库对 C99 标准的支持可能被裁剪，或者需要特定的宏开关（如 __STDC_FORMAT_MACROS）才能开启 PRId64 等宏定义。
• 代码依赖：OpenHarmony 的底层安全组件依赖了 inttypes.h 中的格式化宏。

3. 解决方案（推荐）

为了避免修改 OpenHarmony 的核心源代码（保持代码纯净），建议在板级配置文件中通过编译参数注入宏定义。

找到当前开发板的全局配置文件，通常位于：
device/board/{厂商}/{板子型号}/liteos_m/config.gni

在 board_cflags 中添加 -DPRId64=\"lld\"：

# device/board/csg/hc32f467_board/liteos_m/config.gniboard_cflags = ["-mcpu=cortex-m4","-mthumb",# ... 其他原有参数 ...# 【新增】强制定义 PRId64 为 "lld" (long long decimal)"-DPRId64=\"lld\"",
]

问题二：enum constant in boolean context 警告被视为错误

1. 报错现象

修复完上一个问题后，继续编译遇到了新的报错：

[OHOS ERROR] ../../../base/security/device_auth/services/group_manager/src/group_operation/group_operation_common.c:156:9: error: enum constant in boolean context [-Werror=int-in-bool-context]

2. 原因分析

• 类型不匹配：IsLocalDevice 函数预期返回 bool 类型，但代码逻辑中返回了 HC_ERR_DB（这是一个 int 类型的枚举错误码）。
• 编译器检查变严：较新版本的 GCC 增加了 -Wint-in-bool-context 检查，认为将枚举值直接当作布尔值返回可能存在逻辑风险。
• Werror 策略：OpenHarmony 编译选项默认开启了 -Werror，将所有警告视为错误，导致编译中断。

3. 解决方案（推荐）

同样，为了不修改系统源码逻辑，我们可以通过关闭该特定警告来通过编译。

继续修改同一个板级配置文件 config.gni，在 board_cflags 中添加 -Wno-int-in-bool-context：

# device/board/csg/hc32f467_board/liteos_m/config.gniboard_cflags = ["-mcpu=cortex-m4","-mthumb",# 【新增】解决 PRId64 报错"-DPRId64=\"lld\"",# 【新增】忽略 "枚举在布尔上下文中使用" 的警告"-Wno-int-in-bool-context",
]

总结与最佳实践

在进行 OpenHarmony 设备开发时，遇到编译报错时的排查思路：

1. 区分环境：明确是宿主机缺文件还是交叉编译工具链缺文件（find /usr/include 通常是误导）。
2. 不动源码：尽量避免直接修改 base/ 或 foundation/ 目录下的 .c/.h 源码。这些代码是系统核心，修改后不利于后续 OTA 或代码同步。
3. 善用 GN 配置：
   • 如果问题只影响单个模块，修改该模块的 BUILD.gn。
   • 如果问题是由于板级工具链（Compiler/Libc）特性导致的（如本文案例），最好修改 板级全局配置 (config.gni)，这样能一劳永逸地解决该板子下所有模块的类似问题。

通过上述配置修改后，重新执行 hb build，编译顺利通过。
