linux下通过jni编译CUDA代码生成动态链接库遇到的问题 nvcc -fPIC

错误类型：

      relocation R_X86_64_32 against `.rodata' can not be used when making a shared object

一般c++程序编译生成动态链接库时，我们会使用-fPIC 和 -shared编译参数，至于具体参数说明这里不详细介绍。nvcc本身不支持-fPIC编译参数，但是却提供了-Xcompiler

用途上，使用nvcc -h可以发现，这是提供了向低级编译工具(gcc)传递编译参数的功能，因此在编译.cu文件时，在nvcc后加上 -shared -Xcomplier -fPIC 即可链接成功

最后贴上编译写的shell脚本
