我最近又开始挖一些加密货币，我想试试 Monero (XMR)。CPU 挖矿机 xmrig 运行良好，但我在安装 GPU 挖矿机时遇到了问题。
我已经做了什么
我已经安装了 GTX 1070 的图形驱动程序（我使用的是 375.66）
itssme@muhbuntu:~$ nvidia-smi

Use 'nvcc -ccbin clang-3.8' to use that instead.

问题
错误：未找到受支持的 gcc/g++ 主机编译器，但 clang-3.8 可用。请使用“nvcc -ccbin clang-3.8”来使用它。
问题似乎是 CUDA 8.0 不支持 gcc 6。那么我该如何使用 clang 来代替呢？（我已经通过 apt 安装了它）
答案1
使用 clang-3.8 仍然会出现链接错误。不过，我通过执行以下操作成功让 ccminer 在 Ubuntu 17 上进行编译：
sudo apt-get install gcc-4.9
./configure.sh
在 Makefile 中编辑以下几行：
CXX = g++-4.9
NVCC = /usr/local/cuda/bin/nvcc -ccbin gcc-4.9
ac_ct_CC = gcc-4.9
ac_ct_CXX = g++-4.9
最后：
make
祝你好运！
答案2
快速修复：打开 makefile，搜索 nvcc（使用 nano 按 CTRL+W，输入“nvcc”）并将其替换为“nvcc -ccbin clang-3.8”，保存 makefile 并再次 make。
答案3
选择编译器的最佳方式是将适当的变量传递给 ./configure：
sudo apt-get install g++-4.9
CC=gcc-4.9 CPP=cpp-4.9 CXX=g++-4.9 ./configure
目前，nvcc 似乎不喜欢 5 以上的 GCC 版本。
答案4
编辑 Makefile 并注释以下行：
#scrypt/salsa_kernel.o: scrypt/salsa_kernel.cu
# $(NVCC) $(JANSSON_INCLUDES) -I. -I/usr/local/cuda/include -O3 -lineno -Xcompiler -Wall -D_FORCE_INLINES -gencode=arch=compute_20,code=\"sm_21,compute_20\" -o $@ -c $<
# These kernels are for older devices (SM)
#scrypt/test_kernel.o: scrypt/test_kernel.cu
# $(NVCC) $(JANSSON_INCLUDES) -I. -I/usr/local/cuda/include -O3 -lineno -Xcompiler -Wall -D_FORCE_INLINES -gencode=arch=compute_20,code=\"sm_20,compute_20\" -o $@ -c $<
#scrypt/fermi_kernel.o: scrypt/fermi_kernel.cu
# $(NVCC) $(JANSSON_INCLUDES) -I. -I/usr/local/cuda/include -O3 -lineno -Xcompiler -Wall -D_FORCE_INLINES -gencode=arch=compute_20,code=\"sm_21,compute_20\" -o $@ -c $<
然后运行：
make
它对我有用。
