我在github上clone了一个人的代码，作者说他用gcc 4.8.4是成功的。于是我用homebrew 装了gcc48. 现在我电脑的gcc 版本是4.8.5 。可是跑代码的时候出现了error:
g++-4.8 -c -pipe -O3 BurstyBTM.cpp -o BurstyBTM.o
BurstyBTM.cpp: In member function 'Pvec<double> BurstyBTM::compute_pz_b(Biterm&)':

现在剩下的error:

Pmat<double> pw_z = nwz.normr(beta);

请问各位大大应该如何解决？谢谢！
编译有错误阿，返回值什么的竟然不一致，是平台问题导致的么。。
虽说作者说用gcc的某个版本能编译成功，但能保证在任意平台上都行么。。
贴上来github的链接阿
