我的 makefile 无法完成，因为命令：
makeinfo -I . as.texinfo
失败。有没有办法跳过这一步，因为它只是为了编译文档？
以下是 make 输出的最后一部分：

答案1
我插入了：
print-%:
@echo '$*=$($*)'
进入我的 Makefile 然后执行：
make print-MAKEINFO
显示 makefile 中 MAKEINFO 的值：
MAKEINFO = `if [ -f $$r/texinfo/makeinfo/makeinfo ] ; \
then echo $$r/texinfo/makeinfo/makeinfo ; \
else if (makeinfo --version | egrep 'texinfo[^0-9]*([1-3][0-9]|[4-9])') >/dev/null 2>&1; \
then echo makeinfo; else echo $$s/missing makeinfo; fi; fi`
并收到此错误：
/bin/sh: 1: Syntax error: "(" unexpected
Makefile:25: recipe for target 'print-MAKEINFO' failed
make: *** [print-MAKEINFO] Error 2
所以我将 MAKEINFO 设置为：
MAKEINFO =
并运行了 make，似乎没有问题地完成了。
