当我尝试编译我的CUDA程序时，出现以下错误：
b.o: In function `mul_wrapper':

我的make文件如下所示：
run: main.o b.o
gcc -fPIC -L /usr/local/cuda/lib -lcudart -o run main.o b.o
main.o: main.c b.h
gcc -fPIC -I /usr/local/cuda/include -c -o main.o main.c
b.o: b.cu b.h
nvcc -Xcompiler -fPIC -ccbin clang-3.8 -c -o b.o b.cu
似乎问题与我的系统上找不到文件“/ usr / local / cuda / include”和“/ usr / local / cuda / lib”有关。我使用的是Ubuntu 17.04并且已经使用apt安装了CUDA工具包。我听说用apt安装CUDA工具包不会创建/ usr / local / cuda / *文件，所以我尝试从运行文件安装它，但是要安装faild。
更新：我重新安装了CUDA工具包，现在我有/ usr / local / cuda / *目录，但问题仍然存在。
