没有用uic生成的头

Question

QtCreator不想创建我的ui头文件。当我在终端中输入uic时，它会说：

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

我已经在我的主文件夹中安装了Qt5，Qt可以毫无问题地识别它。在设置中，它在好文件夹中。诺马利它不应该有任何问题！但是它有，所以我必须手工创造我的形式：

./.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

如果你需要更多的信息，问我！

来自@bibi的有用评论：

看起来您的路径不包括~/.Qt/5.5/gcc_64/bin/，和/或不在常规路径之前。正如bibi所说，"which qmake uic“的输出是什么？

在终端上键入：

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

(可能需要其他路径)，然后从这个终端运行agin。如果它成功了，那么将这个路径添加到您的~/.bashrc中，使其永久化。

但是我看到的根本问题是为什么手动安装Qt5？(为什么在隐藏目录中？)我确实需要一个自定义的Qt版本，它不会安装在您的系统文件中，更好的安装位置可以是/opt。加上上面解释的匹配的PATH设置。

如果您不需要自定义Qt，那么每个Linux发行版都可以很高兴地安装Qt4和Qt5，然后您可以选择在.pro文件中使用哪个版本，如下所示：

编辑：

“我用Qt的官方安装程序安装了它。我应该如何在Ubuntu 15.10上安装它呢？”

通常的方法是绝对不从某些Qt的归档中安装它。您有一个包/维护人员的发行版，您应该信任他们。因此，对于Qt4安装来说，应该是sudo apt-get install qt-sdk。对于Qt5，我不知道，但是一点apt-cache search qt5和/或googling就可以了。

编辑2：

对于Qt5安装，至少在我的virtualbox Ubuntu14-04(我运行Debian)上，基本包应该类似于qtbase5-dev

查看它将安装的依赖项列表: qt5-qmake、qtbase5 5-dev-tools、libs等。

因此，根据您想要开发的apt-get install应用程序的类型，再加上后者，可能会有更多的软件包(例如，带有dbus或这个或那个的Qt5应用程序)。

Answer 2

我也有同样的问题。我所有的Qt5包都安装好了，但是在我的linux (CentOS)系统上找不到uic，但是uic-qt5是！

因此，执行以下操作对我来说是有效的：

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