步骤1

通过brew install gcc --without-multilib
的openmp支持获取gcc-6.x.x

终端

Ben$ brew install gcc --without-multilib
Error: gcc-5.3.0 already installed
To install this version, first `brew unlink gcc`

Ben$ brew unlink gcc
Unlinking /usr/local/Cellar/gcc/5.3.0... 1288 symlinks removed

Ben$ brew install gcc --without-multilib
[26 minutes later]
==> Summary
  /usr/local/Cellar/gcc/6.2.0: 1,358 files, 238.3M, built in 26 minutes 20 seconds

步骤2

克隆存储库git clone --recursive https://github.com/dmlc/xgboost

终端

Ben$ git clone --recursive https://github.com/dmlc/xgboost

步骤3

使用以下命令构建cd xgboost; cp make/config.mk ./config.mk; make -j4

注意：如果您使用OSX El Capitan，brew会安装gcc最新版本的gcc-6。因此，您可能需要修改Makefile＃L46并将gcc-5更改为gcc-6。之后在make / config.mk中将gcc-5 / g ++ - 5更改为gcc-6 / g ++ - 6然后使用以下命令进行构建

嗯。不完全确定在这做什么。我在xgboost/中看到一个名为“Makefile”的文件。在里面我看到很多我不理解的东西，但这些线看起来很相似

Makefile（摘录）

# on Mac OS X, force brew gcc-6, since the Xcode c++ fails anyway
# it is useful for pip install compiling-on-the-fly
OS := $(shell uname)
ifeq ($(OS), Darwin)
export CC = $(if $(shell which gcc-6),gcc-6,$(if $(shell which gcc-mp-6), gcc-mp-6, clang))
export CXX = $(if $(shell which g++-6),g++-6,$(if $(shell which g++-mp-6),g++-mp-6, clang++))
endif

要忽略这一点并继续......

终端

Ben$ cd xgboost; cp make/config.mk ./config.mk; make -j4

Step4（说明here？）

如果您想使用最新的xgboost版本编译xgboost，使用library(devtools); install('xgboost/R-package') 手动安装xgboost包（相应地改变路径）你在哪里编译xgboost）。

新R会话

library(devtools)
install("/Users/Ben/xgboost/R-package")

失败:(我哪里出错？

Answer 1

我的方法是在你的第一个（更新gcc）和第二个（克隆）步骤之后，不需要构建任何东西（它们用于其他语言，如python）

3）更新〜/ .R / Makevars

4）从克隆xgboost / R-package / configure更改ac_pkg_openmp到yes https://github.com/dmlc/xgboost/issues/2503
