Linux From Scratch 7.2：在第 6 章中制作 binutils-2.22 时出错

Question

执行时出现以下错误 make tooldir=/usr

完整的输出在这里，我使用的页面在这里

谁能帮我？

编辑：

/usr/include/stdlib.h （第 470 行）

extern void *malloc (size_t __size) __THROW __attribute_malloc__ __wur;

binutils-2.22/libiberty/regex.c （第 130 行）

char *malloc ();

Answer 1

问题是编译代码时未定义 STDC_HEADERS。请参阅该版本 regex.c 的第 47 行。发生这种情况可能是因为您没有跑步configure，或者您跑了但出了问题。

如果您尚未运行configure，请继续运行它：

./configure   

如果您运行它，它应该生成一个名为 的文件，config.h该文件应该用于#define将宏定义STDC_HEADERS为某个值。如果没有，您使用的编译器可能缺少它所依赖的东西（例如系统头文件）或者配置错误或安装不正确。

正如我在上面的评论中提到的，您使用的 binutils 版本现在已经有 4 年多了，我认为您应该使用更新的版本。
