Mac OS X鏈接器

Question

因此，我嘗試為Mac OS X Mavericks編譯其中一種山寨幣（比特幣副本）QT客戶端，並在一段時間后失去了所有內容的組合（boost，db48，miniupnpc，qt 4.8.5和qt creator 2.5.2），我可以進行編譯代碼，但是到達鏈接文件階段時，出現“架構x86_64的未定義符號”錯誤。 這是整個輸出：

我確實嘗試過很多討論Boost和鏈接問題的線程，並且嘗試按照最受歡迎的線程中的建議使用g ++或clang ++進行編譯，但是似乎沒有任何效果。

我真的很感謝您的幫助。 我認為，如果有人已經編譯了Mac OS QT客戶端，應該很清楚出了什么問題。

最好的祝福

Answer 1

所以我找到了解決方案，現在可以使用了，但是我不確定哪個解決了問題：

• 從Homebrew（通過brew install qt）獲取Qt，而不是從Macports或官方網站獲取

• 要求Macports安裝帶有+ Universal標簽的boost和其他依賴項

  sudo port install boost +universal

• 然后我只用了qmake和make進行編譯（如處所述）

我認為這是第二個解決方案，因為它編譯了64位庫。

謝謝bibi向我指出32/64位問題:)

Answer 2

看起來您正在為64位構建，但某些庫為32位，請嘗試在.pro中強制使用

CONFIG+=x86
