Error: "expected ‘:’, ‘,’, ‘;’, ‘}’ " and "struct has no member named"

Question

我找不到任何遗漏的括号。有什么问题？

#ifndef PROCINFO_H_
#define PROCINFO_H_
#include <linux/limits.h>
#include <elf.h>

 enum boolean {f,t};

typedef struct {

    enum boolean fileHdr = 0;
    enum boolean programHdr=0;
    enum boolean sectionHdr = 0;
    enum boolean info = 0;
    enum boolean def = 0;
} procInfo;

typedef struct {
    char filename[NAME_MAX]; 
    procInfo info;
} procFile;


#endif /* PROCINFO_H_ */

错误：

expected ‘:’, ‘,’, ‘;’, ‘}’ or ‘__attribute__’ before ‘=’ token  
make: *** [src/subdir.mk:20: src/elfViewer.o] Error 1

您不能在 typedef 声明中初始化 C 中结构的数据成员，因为您正在这样做

typedef struct {

    enum boolean fileHdr = 0;
    enum boolean programHdr=0;
    enum boolean sectionHdr = 0;
    enum boolean info = 0;
    enum boolean def = 0;
} procInfo;

你需要写

typedef struct {

    enum boolean fileHdr;
    enum boolean programHdr;
    enum boolean sectionHdr;
    enum boolean info;
    enum boolean def;
} procInfo;

定义此类对象时，您可以为其提供初始化，例如

pricinfo info = { 0 };

Error: "expected ‘:’, ‘,’, ‘;’, ‘}’ " and "struct has no member named"
