c – 在Mac上安装xgboost失败 – ar:未指定归档成员

我想在Mac上安装xgboost.我按照 github上的说明进行操作,但是当我运行make -j4时出现错误:

如果我只运行make(没有-j4)我得到:

$make
ar crv lib/libxgboost.a 
ar: no archive members specified
usage:  ar -d [-TLsv] archive file ...
    ar -m [-TLsv] archive file ...
    ar -m [-abiTLsv] position archive file ...

    ar -t [-TLsv] archive [file ...]
    ar -x [-ouTLsv] archive [file ...]
make: *** [lib/libxgboost.a] Error 1

知道是什么导致了这个以及如何解决它吗?

虽然我可能错了,但我认为是因为mac上的存档实用程序太旧了(从2005年开始):

$man ar

AR(1)                     BSD General Commands Manual                    AR(1)

NAME
     ar -- create and maintain library archives

SYNOPSIS

Darwin                           July 27, 2005                          Darwin

任何想法如何更新到OS X上的最新版本?

这是makefile供您参考:
