未使用 uic 生成 header

Question

QtCreator 不想创建我的 ui header 文件。当我在终端输入 uic 时，它告诉我：

louis@Krusty:~$ uic
uic: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/uic': No such file or directory

我在主文件夹中安装了 Qt5，Qt 可以毫无问题地识别它。在设置中，它位于 good 文件夹中。通常它应该没有任何问题！但是它有，所以我必须手动创建我的表格：

./.Qt/5.5/gcc_64/bin/uic Documents/lab/Qt/OpenPlane/AirplaneEditor.ui  -o ui_AirplaneEditor.h

这是我的 QMake :

QT += widgets

SOURCES += \
    main.cpp \
    Airplane.cpp \
    AirplaneOverview.cpp \
    AirplaneManager.cpp \
    AirplaneEditor.cpp

HEADERS += \
    Airplane.h \
    AirplaneOverview.h \
    AirplaneManager.h \
    AirplaneEditor.h \
    ui_AirplaneEditor.h # By hand

FORMS += \
    AirplaneEditor.ui

如果您需要更多信息，请问我！

来自@bibi 的有用评论：

看起来您的 PATH 不包括 ~/.Qt/5.5/gcc_64/bin/，and/or 不在常规路径之前。正如bibi所说，“which qmake uic”的输出是什么？

在终端上输入：

export PATH=$HOME/.Qt/5.5/gcc_64/bin/:$PATH

（可能需要其他一些路径）然后从这个终端开始运行。如果它成功了，请将此 PATH 添加到您 ~/.bashrc 以使其永久化。

但我认为根本问题是你为什么要手动安装 Qt5??? （为什么在隐藏目录中？）我确实需要自定义版本的 Qt，它不会安装在您的系统文件中，更好的安装位置可能是 /opt。加上上面解释的匹配 PATH 设置。

如果您不需要自定义 Qt，每个 Linux 发行版都可以愉快地安装 Qt4 和 Qt5，然后您可以选择要在 .pro 文件中使用的版本，如下所示：

编辑：

"I installed it with the official installer from Qt. How should I install it on Ubuntu 15.10?"

常规方法绝对不是从某些 Qt 的存档中安装它。你有 packagers/maintainers 的发行版，你应该相信他们。所以对于 Qt4 安装来说，它将是 sudo apt-get install qt-sdk。对于 Qt5 我不知道，但是 apt-cache search qt5 and/or 谷歌搜索应该可以解决问题。

对于 Qt5 安装，至少在我的 virtualbox Ubuntu 14-04（我运行 Debian）上，基本包应该是 qtbase5-dev:

查看它将安装的依赖项列表：qt5-qmake、qtbase5-dev-tools、库等

所以 apt-get install 那个，加上后者可能还有几个包，具体取决于您要开发的 Qt5 应用程序的类型（例如带有 dbus 或这个或那个的 Qt5）。

Answer 2

我遇到了同样的问题。我的所有 Qt5 软件包都已安装，但在我的 linux (CentOS) 系统上找不到 uic，但 uic-qt5 是！

所以执行以下对我有用：

$ uic-qt5 AirplaneEditor.ui -o ui_airplaneeditor.h

未使用 uic 生成 header

No header generated with uic
