c++ - Trec_eval 使用 cygwin 出错

Question

我正在使用 trec_eval.9.0 并尝试使用 cygwin 在其中运行 make 命令:

Arezo@DESKTOP-JNNKBAS /cygdrive/d/Trec_eval/trec_eval.9.0 
 $ make

但是出现了以下错误:

 from m_ndcg_cut.c:8:
 m_ndcg_cut.c:12:8: error: expected ‘)’ before ‘/’ token
 double log2(double x);

 Makefile:54: recipe for target 'trec_eval' failed
 make: *** [trec_eval] Error 1

Answer 1

尝试添加

#undef log2

在 sysfunc.h 中的 #include 部分之后

这帮助我编译了这个工具。
