gfortran找不到那里的图书馆 [英] gfortran can't find library that IS there

问题描述

我无法将我的程序链接到一个库。我从来没有这样做过，所以我可能做一些愚蠢的事情，但据我所知，我做的是正确的事情。我需要将我的程序 foo.f90 链接到位于我家下方目录中的库 libbar.a 目录。我输入命令：

  gfortran -c foo.f90 
 gfortran -o foo foo.f90 -L / directory / of / library -llibbar.a 
  

但是这会引发：

  ld：找不到-llibhealpix.a的库b $ b  

当然 libhealpix.a 是真正的库（而不是 libbar.a ）

关于为什么会发生这种情况的任何想法？ 试试 -lbar （或者可能 -lhealpix ，如果这是真正的库名）。

-lxyz 会导致搜索名为 libxyz.a 的文件。因此，如果指定 -llibbar.a ，那么文件需要命名为 liblibbar.aa 。

您也可以在gfortran命令行中简单指定存档文件的路径和全名： gfortran -o foo foo.f90 / directory / of / library /libbar.a

I'm having trouble linking my program to a library. I've never done this before so I'm probably doing something stupid, but as far as I can tell I'm doing the right thing. I need to link my program foo.f90 to a library libbar.a which is in a directory elsewhere below my home directory. I enter the command:

gfortran -c foo.f90
gfortran -o foo foo.f90 -L/directory/of/library -llibbar.a

But this throws:

ld: library not found for -llibhealpix.a

Where of course libhealpix.a is the real library (rather than libbar.a)

Any ideas as to why this would occur?

解决方案

Try -lbar (or perhaps -lhealpix, if that's the real library name).

-lxyz results in a search for a file named libxyz.a. Consequently, if you specify -llibbar.a then the file needs to be named liblibbar.a.a.

You could also simply specify the path and full name of the archive file on the gfortran command line: gfortran -o foo foo.f90 /directory/of/library/libbar.a
