Linux perf编译not define GELF_ST_VISIBILITY问题解决方案

Posted 2022-05-19 smartvxworks

原因：

symbol-elf.c文件缺少对应GELF_ST_VISIBILITY定义

解决办法：

       添加如下定义：

#ifndef ELF32_ST_VISIBILITY
#define ELF32_ST_VISIBILITY(o)	((o) & 0x03)
#endif

/* For ELF64 the definitions are the same.  */
#ifndef ELF64_ST_VISIBILITY
#define ELF64_ST_VISIBILITY(o)	ELF32_ST_VISIBILITY (o)
#endif

/* How to extract information held in the st_other field.  */
#ifndef GELF_ST_VISIBILITY
#define GELF_ST_VISIBILITY(val)	ELF64_ST_VISIBILITY (val)
#endif
