我是 Ubuntu 的新用户,如果我的问题太明显,请原谅我。
我在VirtualBox中安装了32位的Ubuntu 11.10,我想用 构建一个项目qmake-qt4
,问题是我对此一无所知,我在谷歌上搜索过,但我找到的是如何使用一个项目文件生成另一个项目文件和一个Makefile,但是我下载的项目包中有所有这些(Makefile,.pro文件),直接输入make
命令得到的结果如下:
make: Nothing to be done for `first'
如果我使用qmake-qt4 -project, qmake-qt4, make
:
/usr/bin/qmake-qt4 -o Makefile GATE_PET_2_STIR.pro
g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_WEBKIT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4 -I. -Iinclude/qwt-6.0.2 -Iinclude/root -IViewer -I. -I. -o viewer.o Viewer/viewer.cpp

我应该怎么做才能修复这些错误?
答案1
首先,将代码恢复到之前的样子。运行时,qmake-qt4 -project
你破坏了之前的代码(可能是正确的).pro
。
回到开始后,导航到包含 .pro 的目录并输入qmake-qt4
。这将Makefile
根据 .pro 中的特征生成一个。完成后,运行make
。这应该会构建整个项目(假设您已经拥有qt4 构建依赖项已安装)。如果没有,下载 Qt 4 源代码并关注这些说明。
