crosstools-ng找不到pthread.so

问题描述

我试图用crosstools-ng来编译使用pthread的程序，但由于某些原因链接程序找不到该库。我已经检查过，并且这些库位于由 -L 指定的链接路径中是参数。

以下是错误：

  / home / *** /raspberrypi/toolchain/lib/gcc/arm-unknown-linux-gnueabi/4.6.3/../../../../ arm-unknown-linux-gnueabi / bin / ld：找不到/ lib / arm-linux-gnueabihf / libpthread.so.0 
 
 /home/***/raspberrypi/toolchain/lib/gcc/arm-unknown-linux-gnueabi/4.6.3/../。 ./../../arm-unknown-linux-gnueabi/bin/ld：找不到/usr/lib/arm-linux-gnueabihf/libpthread_nonshared.a 
  

为什么ld不能找到路径内的文件？

解决方案

  / * GNU ld脚本
使用共享库，但某些函数仅在
静态库中，所以请尝试其次。 * / 
 OUTPUT_FORMAT（elf32-littlearm）
 GROUP（/lib/arm-linux-gnueabihf/libpthread.so.0 /usr/lib/arm-linux-gnueabihf/libpthread_nonshared.a）
  

至

  / * GNU ld脚本
使用共享库，但某些函数仅在
静态库中，因此请尝试其次。 * / 
 OUTPUT_FORMAT（elf32-littlearm）
 GROUP（libpthread.so.0 libpthread_nonshared.a）
  

I am trying to use crosstools-ng to compile a program that uses pthread, however for some reason the linker can't find the library. I have checked and the libraries are located in the link path specificed by -L is the arguments.

Here is the error:

/home/***/raspberrypi/toolchain/lib/gcc/arm-unknown-linux-gnueabi/4.6.3/../../../.. /arm-unknown-linux-gnueabi/bin/ld: cannot find /lib/arm-linux-gnueabihf/libpthread.so.0

/home/***/raspberrypi/toolchain/lib/gcc/arm-unknown-linux-gnueabi/4.6.3/../../../../arm-unknown-linux-gnueabi/bin/ld: cannot find /usr/lib/arm-linux-gnueabihf/libpthread_nonshared.a

Why can't ld find the file that is within the path?

解决方案

Edit your .../usr/lib/arm-linux-gnueabihf/libpthread.so:

/* GNU ld script
Use the shared library, but some functions are only in
the static library, so try that secondarily.  */
OUTPUT_FORMAT(elf32-littlearm)
GROUP ( /lib/arm-linux-gnueabihf/libpthread.so.0 /usr/lib/arm-linux-gnueabihf/libpthread_nonshared.a )

to

/* GNU ld script
Use the shared library, but some functions are only in
the static library, so try that secondarily.  */
OUTPUT_FORMAT(elf32-littlearm)
GROUP ( libpthread.so.0 libpthread_nonshared.a )
