我有一个在子目录中有MCC生成代码的项目。我想访问在父目录中的代码中声明的变量。为什么不承认或接受对外声明？当我试图编译MCC代码时，我得到以下文件：干净的成功（总时间：51毫秒）c:\程序文件（x86）Microchip xC16v1.32 bin xC16 gcc.exe“MCCI”。MyPo.MePux/McPU＝24FJ128GA610-MMD -MF“构建/默认/生产/ MCCH生成的文件/ Pin管理器.O.D”-MNO EDS警告-G-OMF＝ELF-DXPRJIOUTY =默认-没有遗留LIBC-O0-MSMARI IO＝1墙-MSFR警告= OB-NBPt/MaGeFieldList.MK：302：目标“构建/默认/生产/ MCCH生成文件/ Pin管理器”的配方。O'FrestMcCyPrimeDyFrase/Pin管理器。C:54：16:错误：在“SyrWorkFrase'McCyPrimeAddioStudio/Pin管理器”之前的预期“=”、“、”、“ASM”或“AY属性”。错误：“SunRoSurror”未声明（在这个函数中首次使用）McCyPrimeAddixFixs/PixMealth.C:223：13:注意：每个未声明的标识符只对其出现的每个函数只报告一次：**[Bug/Deule/Mutux/McCyPrimeAdxFixs/PixMaung.O]错误255构建失败（退出值2，总时间：445毫秒）

不包含StInt.h头，因此Unt8It TyPulf对于编译器来说是不可见的。
以上来自于百度翻译 以下为原文 The stdint.h header is not included, so the uint8_t typedef is not visible to the compiler. |
