Question

以下是我尝试安装xgboost的过程：

git clone --recursive https://github.com/dmlc/xgboost
git submodule init
git submodule update
cp make/mingw64.mk config.mk

直到我在我的git bash中运行代码

才很好

 make -j4

出错了：

    F:/mingw64/x86_64-w64-mingw32/include/stdio.h:450:83: error: 'FILE* std::fopen(const char*, const char*)' should have been declared inside 'std'

我找到一些参考资料，说明原因可能与Windows系统和Unix之间的区别有关，但它超出了我的知识范围。

我安装了mingw64

Answer 1

github page上出现了一个问题。

克隆后，请结帐到版本9a48a40，然后重复上面执行的步骤。我遇到了同样的问题，这对我有用。

从链接引用：

修正了，只需克隆回购然后结帐到9a48a40直到他们修复它，最后提交中的内容必须搞砸编译：
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost
git checkout 9a48a40
git submodule init
git submodule update

在windows7，python2.7中安装xgboost4.0时发生错误
