PointNet++ ext_op 算子编译报错

[zjuncd]

基于 Docker 编译源码：

基础镜像：registry.baidubce.com/paddlepaddle/paddle:2.1.2-gpu-cuda11.2-cudnn8

Paddle 源码编译通过，但是在编译算子时报错，ext_op/src

报错关联对象：

paddle/fluid/platform/complex.h(115): error: explicit type is missing ("int" assumed)

paddle/fluid/platform/complex.h(115): error: qualified name is not allowed

paddle/fluid/platform/complex.h(115): error: expected a ")"

你好，这个是1.6版本静态图的custom op编译，如果需要用这个可能需要用Paddle 1.6版本，并且编译Paddle和编译ext_op的环境，比如g++， cmake版本这些需要一致
