未定义对`blacs_gridinfo_‘的引用

Question

在构建LSDMap (局部缩放扩散图)时，我得到了一个未定义的引用错误。哪些库包含缺失的引用？

他们来自BLACS。请注意，blacs_gridinfo_和一个简单的谷歌搜索识别出其他的(如google.com/search?q=pdlarnv&oq=pdlarnv)也来自于BLACS或ARPACK。

Etime()是某些编译器(https://gcc.gnu.org/onlinedocs/gfortran/ETIME.html)中的非标准内在函数，但您的编译器并不知道这一点。你得找点东西来替代它。

一般来说，我建议你使用你最喜欢的搜索引擎搜索没有下划线的遗漏的名字，应该不难找到相应的库。
