the situation is same when build roi_pooling, roi_align and roi_crop. The answers from google are tried but no one cannot solve this error. Thank you for your answer!

[chriszhenghaochen]

It happens because your compiler does not support such syntax, try switch your gcc compiler flag via

export CXXFLAGS="-std=c++11"
export CFLAGS="-std=c99"

[dami23]

@chriszhenghaochen sincerely thank you for your help, it worked! Thank you again!

@nationalflag have you solved this problem?

[ycao6928]

@chriszhenghaochen so helpful!

[JiasiWang]

@nationalflag @jwyang I meet the same problem, could you please help me? I use Anaconda 2.7 and cuda 8.0, the version of pytorch is 0.4.1. Thank you so much!

[qxin]

@JiasiWang try to change to pytroch 0.4.0, as shown by https://github.com/jwyang/faster-rcnn.pytorch/issues/235

[wujiahongPKU]

I have the same problem, I can not use the "export CXXFLAGS="-std=c++11"
export CFLAGS="-std=c99" " these two sentences to solve my problem, what should I try?
