Qt的鏈接錯誤

Question

我配置qtx11有下列選項

的./configure -prefix /的iTalk/qtx11 -prefix安裝-bindir /的iTalk/qtx11安裝/ bin中-libdir /的iTalk/qtx11安裝/ libalkdir/iTalk/qtx11-install/doc -headerdir/iTalk/qtx11-install/include -datadir/iTalk/qtx11-install/data -examplesdir/iTalk/qtx11-install/examples -demosdir/iTalk/qtx11-install/demos -debug。

現在我得到下面的錯誤中的Fedora Core 6

能否請你告訴我問題出在哪裏？

Answer 1

您缺少對FontConfig的引用。

./configure需要一個-no-fontconfig開關，但更好的是要弄清楚爲什麼./configure沒有正確包含FontConfig。 （你發佈的日誌還沒有足夠回到甚至找出失敗的鏈接命令是什麼）

Answer 2

這看起來像基於Red Hat的系統和他們使用的舊版本FontConfig的已知問題。在http://theitdepartment.wordpress.com/2009/03/15/centos-qt-fcfreetypequeryface/有很好的指導來解決這個問題。

Answer 3

問題是，由紅帽提供的fontconfig版本太舊，並且丟失了一個符號（我讀了它是低的子sub版本號，導致丟失的符號）。如果你只是簡單地更新fontconfig，它似乎不適用於我，因爲它發現最舊的版本仍然存在，但是當我更改makefile以直接鏈接到新的libfontconfig.so時，它工作正常。在.pro文件中添加以下行：LIB + = /path/to/your/NewFontConfiglib.so.XX此外，只是做一個yum更新不起作用，它說包最新，我讀了一篇文章，展示瞭如何添加新的一個。後來，我決定我需要構建我的應用程序獨立，所以我開始構建一個靜態版本的Qt，並陷入了同樣的問題.....我不知道如何修改該生成文件，但遇到了這篇文章，希望它將工作。看看這篇文章：CentOS 5.2 + Qt 4.5 + FcFreeTypeQueryFace
