[交流] 【求助成功】VASP5.2 编译出现这样的warning,对编译出来的vasp有影响吗?已有4人参与

如题,我在编译vasp5.2时出现了这样的warning,总共出现了3次,该怎么解决?对编译出来的vasp有影响吗?
     nonlr.f90(1797): warning #7866: The statement following this DEC loop optimization directive must be an iterative do-stmt, a vector assignment, an OMP pdo-directive, or an OMP parallel-do-directive.

属于gcc中的Machine Dependent Options。

用于优化矢量性系统并行计算

早期的DEC公司,已被HP收购,主要推出alpha, Tru64系统,现在演变为HP-UX

如果采购HP-UX,在此类系统上编译优化不会出此问题。别的系统中就可能会给出警告。

显然这不会有任何影响

这个问题和我遇到的一样,楼主可以搜搜我以前的帖子,
建议是把优化级别降低,但是问题还是存在
不过现在看来计算结果没有什么太大的问题。
你可以贴下你的编译文件。

这个问题好像跟BLAS、LAPACK和DCACHE_SIZE 无关。以下是我的makefile:
