@weigao95 hello, I have built your project for 1 week under VS2015 + cuda9.2 + pcl1.8.1, I was almost successful, but this question stopped me:
1>------ 已启动生成: 项目: surfelwarp_app, 配置: Debug x64 ------ 1>libucrtd.lib(log2f.obj) : error LNK2005: log2f 已经在 core_libd.lib(core_lib_generated_SurfelWarpSerial.cu.obj) 中定义 1> 正在创建库 D:/VS_Project/surfelwarp-master/build/apps/surfelwarp_app/Debug/surfelwarp_app.lib 和对象 D:/VS_Project/surfelwarp-master/build/apps/surfelwarp_app/Debug/surfelwarp_app.exp 1>D:\VS_Project\surfelwarp-master\build\apps\surfelwarp_app\Debug\surfelwarp_app.exe : fatal error LNK1169: 找到一个或多个多重定义的符号

help me, thanks @weigao95

it seems that the libucrtd.lib is part of the Windows SDK, and core_libd.lib is a local built file of this project, the question is a variable or function log2f is redefined, they are just conflicted, but there is another question that I cannot find any log2f in your project, maybe a header is included for more than one times.
