Mac OS X Linker

Question

所以我试着为Mac OS X Mavericks编译其中一个altcoin（比特币副本）QT客户端，并且在一段时间以后丢失了所有东西（boost，db48，miniupnpc，qt 4.8.5和qt creator 2.5.2）我可以编译代码，但是当到达链接文件的阶段时，出现“Undefined symbols for architecture x86_64”错误。这里是整个输出：

我真的试图去通过大量的线程提升的谈话和连接问题，我试着用G ++或作为最流行的线程建议铛++编译，但似乎没有任何工作。

我真的很感谢一些帮助。我想如果有人已经编译了Mac OS QT客户端，应该很清楚哪里出了问题。

Answer 1

所以我找到了解决办法，现在它的工作，但我说不准哪一个解决了这个问题：

• 从家酿获取QT（BREW安装QT），而不是从MacPorts的或官方网站

• 提出的MacPorts安装升压和其他依赖与标签+通用

  sudo port install boost +universal

• 然后，我只是用QMAKE并编译（如到处描述的）

我想这是解决它的第二个解决方案，因为它编译了64位库。

谢谢你比比来指点我到32/64位问题:)

Answer 2

看起来你正在为64位，但有些库是32位 试图迫使它在的.pro

CONFIG+=x86
