无法从CRAN安装xgboost

Question

[当我想在cenos7（是wsl2）中从cran安装xgboost时，出现此错误，并且我无法通过Google找到任何线索：

In file included from amalgamation/xgboost-all0.cc:68:0:
amalgamation/../src/learner.cc: In member function ‘virtual void xgboost::LearnerImpl::SaveModel(xgboost::Json*) const ’:

make: *** [amalgamation/xgboost-all0.o] Error 1

环境是：

默认gcc版本是4.8.5，为了编译'rstan'，我写了

CXX14 = g++ -std=c++1y
CXX14FLAGS += -fPIC

进入文件〜/ .R / Makevars

我如何成功安装xgboost？

Answer 1

尝试从github（https://xgboost.readthedocs.io/en/latest/build.html#installing-the-development-version）获得开发包：

git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git submodule init
git submodule update
mkdir build
cd build
cmake .. -DR_LIB=ON
make -j$(nproc)
make install

使用默认目标时，将在构建区域中构建R软件包共享库。此外，安装目标使用此共享库在build / R-package下组装软件包文件，并运行R CMD INSTALL。
