当使用Qt + opencv + ffmpeg时，在Mac上找不到体系结构x86_64的符号 [英] symbol(s) not found for architecture x86_64 on Mac when using Qt+opencv+ffmpeg

问题描述

我正在Mac上使用Qt + opencv + ffmpeg运行一个项目，但是出现错误：架构x86_64找不到符号。

---

.pro的一部分：

  INCLUDEPATH + = / usr / local / include 
 INCLUDEPATH + = / usr / local / include / opencv 
 INCLUDEPATH + = / usr / local / include / opencv2 
 
 LIBS + = -L / usr / local / lib -lavformat -lavcodec -lavutil 
  

---

当我使用GCC（x86 64位/ usr / bin）来编译，它显示

 错误：没有为架构找到符号x86_64 
 / p $ p 
 
 
当我使用Clang（x86 64bit in / usr / bin）进行编译时，会显示
 错误：没有为架构找到符号x86_64 
错误：链接器命令失败，退出代码1（使用-v查看调用） 
  
 
 
 
 
 
 
我使用的是OS X Yosemite 10.10.4 。有没有人知道如何解决它？
解决方案
您已经包含路径与 INCLUDEPATH 而不是图书馆本身与 LIBS  
 
 
 
也许 或这个的答案可以帮助你：
 
I'm running a project using Qt+opencv+ffmpeg on Mac, but it comes to an error: symbol(s) not found for architecture x86_64.



Part of .pro:
INCLUDEPATH += /usr/local/include
INCLUDEPATH += /usr/local/include/opencv
INCLUDEPATH += /usr/local/include/opencv2

LIBS += -L/usr/local/lib -lavformat -lavcodec -lavutil




When I use GCC (x86 64bit in /usr/bin) to compile, it shows 
error: symbol(s) not found for architecture x86_64
When I use Clang (x86 64bit in /usr/bin) to compile, it shows 
error: symbol(s) not found for architecture x86_64
error: linker command failed with exit code 1 (use -v to see invocation)




I'm using OS X Yosemite 10.10.4. Does anybody know how to fix it?
解决方案
You have included the path with INCLUDEPATHbut not the library itselfs with LIBS

Maybe this or this answer helps you:
