Xgboost: Kesalahan instalasi XGBoost Windows

Hai,

Saya menggunakan WIndows 7, mencoba menginstal XGBoost untuk python.
Saya menggunakan GIT Bash untuk melakukannya.
Saya telah mengikuti langkah-langkah di halaman berikut-
https://github.com/dmlc/xgboost/blob/master/doc/build.md#building -on-windows
Saya memiliki versi make berikut di MinGW-
mingw32-make bin 3.82.90-2-cvs-20120902
mingw32-make doc 3.82.90-2-cvs-20120902
mingw32-make lang 3.82.90-2-cvs-20120902
mingw32-make lic 3.82.90-2-cvs-20120902
dan versi g++ berikut-
mingw32-gcc-g++ bin 4.9.3-1
mingw32-gcc-g++ dev 4.8.1-4
mingw32-gcc-g++ doc 4.8.1-4
mingw32-gcc-g++ man 4.9.3-1

Saat menjalankan perintah berikut-
cp make/mingw64.mk config.mk; make -j4
Saya mendapatkan kesalahan berikut untuk perintah kedua-
$ make -j4 g++ -m64 -std=c++0x -Wall -O3 -msse2 -Wno-unknown-pragmas -funroll-loops -Iinclude -DDMLC_ENABLE_STD_THREAD=0 -Idmlc-core/include -Irabit/include -fopenmp -MM -MT build/learner.o src/learner.cc >build/learner.d g++ -m64 -std=c++0x -Wall -O3 -msse2 -Wno-unknown-pragmas -funroll-loops -Iinclude -DDMLC_ENABLE_STD_THREAD=0 -Idmlc-core/include -Irabit/include -fopenmp -MM -MT build/logging.o src/logging.cc >build/logging.d g++ -m64 -std=c++0x -Wall -O3 -msse2 -Wno-unknown-pragmas -funroll-loops -Iinclude -DDMLC_ENABLE_STD_THREAD=0 -Idmlc-core/include -Irabit/include -fopenmp -MM -MT build/common/common.o src/common/common.cc >build/common/common.d g++ -m64 -std=c++0x -Wall -O3 -msse2 -Wno-unknown-pragmas -funroll-loops -Iinclude -DDMLC_ENABLE_STD_THREAD=0 -Idmlc-core/include -Irabit/include -fopenmp -MM -MT build/c_api/c_api_error.o src/c_api/c_api_error.cc >build/c_api/c_api_error.d cc1plus.exe: sorry, unimplemented: 64-bit mode not compiled in Makefile:97: recipe for target 'build/common/common.o' failed mingw32-make: *** [build/common/common.o] Error 1 mingw32-make: *** Waiting for unfinished jobs.... cc1plus.exe: sorry, unimplemented: 64-bit mode not compiled in Makefile:97: recipe for target 'build/c_api/c_api_error.o' failed mingw32-make: *** [build/c_api/c_api_error.o] Error 1 cc1plus.exe: sorry, unimplemented: 64-bit mode not compiled in cc1plus.exe: sorry, unimplemented: 64-bit mode not compiled in Makefile:97: recipe for target 'build/logging.o' failed mingw32-make: *** [build/logging.o] Error 1 Makefile:97: recipe for target 'build/learner.o' failed mingw32-make: *** [build/learner.o] Error 1
Tolong bantu saya menemukan solusi untuk ini. Saya sepertinya tidak bisa melewati masalah ini ......!
