Qt for Linux/X11 - 構建從源

可以下載 Qt 5 源代碼，從下載頁麵。更多信息，拜訪 Qt 快速入門頁麵。

Qt for X11 has some requirements that are given in more detail in the Qt for X11 要求文檔。

Step 1: Installing the License File (Commercially Licensed Qt Only)

若在商業許可下使用 Qt，則 Qt 工具會查找本地許可文件。若正使用二進製安裝程序或商用 Qt Creator，則會自動取齣許可並存儲在本地用戶 Profile (配置文件) 中 ( $XDG_DATA_HOME/Qt/qtlicenses.ini file).

若不使用任何二進製安裝程序或 Qt Creator，可以下載各自的許可文件從您的 Qt 帳戶 Web 門戶並將其保存到您的用戶 Profile (配置文件) 作為 $HOME/.qt-license 。若偏愛不同的位置或文件名，需要設置 QT_LICENSE_FILE 環境變量到各個文件路徑。

Step 2: Unpacking the Archive

Unpack the archive if you have not done so already. For example, if you have the qt-everywhere-opensource-src-%VERSION%.tar.gz package, type the following commands at a command line prompt:

cd /tmp
gunzip qt-everywhere-opensource-src-%VERSION%.tar.gz        # uncompress the archive
tar xvf qt-everywhere-opensource-src-%VERSION%.tar          # unpack it

This creates the directory /tmp/qt-everywhere-opensource-src-%VERSION% containing the files from the archive. We only support the GNU version of the tar archiving utility. Note that on some systems it is called gtar.

Step 3: Building the Library

To configure the Qt library for your machine type, run the ./configure script in the package directory.

By default, Qt is configured for installation in the /usr/local/Qt-%VERSION% directory, but this can be changed by using the -prefix 選項。

cd /tmp/qt-everywhere-opensource-src-%VERSION%
./configure

The 配置選項頁麵包含有關 configure 選項的更多信息。

To create the library and compile all the examples, tools, and tutorials, type:

make

若 -prefix is outside the build directory, you need to install the library, examples, tools, and tutorials in the appropriate place. To do this (as root if necessary), type:

make install

Note that on some systems the make utility is named differently, e.g. gmake. The configure script tells you which make utility to use.

注意： 若以後需要在相同位置重新配置和重構 Qt，確保移除所有先前配置痕跡，通過進入構建目錄並鍵入 make confclean 先於運行 configure 再次。

Step 4: Set the Environment Variables

In order to use Qt, some environment variables needs to be extended.

PATH               - to locate qmake, moc and other Qt tools

This is done like this:

在 .profile (if your shell is bash, ksh, zsh or sh), add the following lines:

PATH=/usr/local/Qt-%VERSION%/bin:$PATH
export PATH

在 .login (in case your shell is csh or tcsh), add the following line:

setenv PATH /usr/local/Qt-%VERSION%/bin:$PATH

If you use a different shell, please modify your environment variables accordingly.

For compilers that do not support rpath you must also extended the LD_LIBRARY_PATH environment variable to include /usr/local/Qt-%VERSION%/lib . On Linux with GCC this step is not needed.
