OSX10.9應用程序崩潰：找不到符號：___strlcat_chk

我有一個與我的MacBook（小牛）完美配合的應用程序。OSX10.9應用程序崩潰：找不到符號：___strlcat_chk

與虛擬機（OSX獅子）努力後，它會崩潰與此回溯：

你有一個想法，以解決這個bug？

以兩個下劃線開頭的名稱保留給編譯器。這個'strlcat'的特定變種可能已經在小牛引入，可能從未打算直接使用。 – zneak

我和其他小牛隊有同樣的問題。只有我的Mac（用於開發此應用程序）不會崩潰... – FBruynbroeck

你的答案是正確的，在轉儲： _psutil_osx.so（從/用戶/用戶/公共/下拉框/ SafeDrive.app /內容/資源/）

缺少符號strlcat_chk它是試圖在運行時使用dlopen（）從libSystem.B導入。 _Chk變體是strlcat（一個字符串連接函數）的更安全版本，它檢查其參數是否存在緩衝區溢出。使用特定版本的XCode構建的應用程序將默認使用此功能，而不是strlcat。它是小牛的LibC的一部分，我相信它是版本997.

如果您有該共享對象的來源，請將_chk更改爲非檢查符號版本（即strlcat），並且應該修復它。否則，您可以嘗試修補二進制文件的字符串表（假設它沒有違反代碼簽名，如果有的話）。您可以使用-mmin-osx-version 10.7（甚至10.6）重新編譯，這可能會解決問題。
