ranlib和静态库 [英] ranlib and static library

问题描述

  libmine.a：可能的不读符号：存档没有索引;运行ranlib添加一个
  

我试着做 ranlib libmine.a 但没有任何变化，它仍然给出了相同的错误。如何解决这个问题？

解决方案

要查看档案中的符号，请使用nm。 b

  nm -s libmine.a 
  

<输出>

子例程的入口点应标记为T，如

 
 00000000 T _sub1 
 00000019 T _sub2 
 

您在ar中使用了哪些开关静态库？我通常使用ar -r作为

  ar -r libmine.a mine.o yours.o 
  

如果您仍然遇到问题，请添加-s选项

  ar -s -r libmine.a mine.o yours.o 
  

另外，请确保路径中没有其他libmine.a文件，或者为您的libmine.a制定明确的路径。链接器可能正在拾取不同的libmine.a。

I am trying to link a static library that I created, but I get this error.

libmine.a: could not read symbols: Archive has no index; run ranlib to add one

I tried to do ranlib libmine.a but nothing changed, it still gives the same error. How can I solve this problem?

解决方案

To see the symbols in an archive, use nm.

nm -s libmine.a

<output>

The entry points to the subroutines should be labled "T" as in

00000000 T _sub1
00000019 T _sub2

What switches did you use in "ar" to make the static library? I usually use "ar -r" as in

ar -r libmine.a mine.o yours.o

If you are still having problems, add the "-s" option

ar -s -r libmine.a mine.o yours.o

Also, be sure that there are no other "libmine.a" files in the path, or make an explicit path to your "libmine.a". It is possible the linker is picking up a different "libmine.a".
