在Ubuntu 17.04上构建CCminer
我最近又开始挖掘一些cryptconcurrencys，我想尝试Monero（XMR）。 CPU miner xmrig工作得很好但是我在安装GPU挖掘器时遇到了问题。
我已经做了什么
我已经为我的GTX 1070安装了图形驱动程序（我使用的是375.66）

从github克隆ccminer

运行“./autogen.sh”和“./configure”

问题
错误：找不到支持的gcc / g ++主机编译器，但是clang-3.8可用。 使用’nvcc -ccbin clang-3.8’代替使用它。
问题似乎是CUDA 8.0不支持gcc 6.所以我怎么能用clang呢？ （我已经通过apt安装了它）
快速修复：打开makefile，搜索nvcc（使用nano它的CTRL + W，输入“nvcc”）并将其替换为“nvcc -ccbin clang-3.8”，保存makefile并再次制作。
使用clang-3.8仍然给我留下链接错误。 但是，我通过执行以下操作设法让ccminer在Ubuntu 17上编译：
sudo apt-get install gcc-4.9 ./configure.sh
编辑Makefile中的以下行：
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
祝好运！
选择编译器的最佳方法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似乎不喜欢比5更新的GCC版本。
编辑Makefile和注释行：
#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。
