我目前正在尝试使QWT 6.1.0在MAC OS X 10.7.5下运行. 我按照此处的说明进行操作-> qwt.sourceforge/qwtinstall.html 我没有在配置文件中进行任何更改.

I am currently trying to get QWT 6.1.0 running under MAC OS X 10.7.5. I followed the instructions over here --> qwt.sourceforge/qwtinstall.html I didn't changed something inside the configuration files.

所以一切正常，但是现在我想在自己的Project中使用qwt-libary. 我在.pro

So everything worked fine, but now I want to use the qwt-libary inside my own Project. I added the following line to my .pro

INCLUDEPATH += /Users/userX/Downloads/qwt-6.1.0/src

因此，我的项目现在可以找到所有头文件. 但是我也必须反对自由主义者.但是我不知道该怎么做. 我试过使用类似这样的东西:

So my Project is now able to find all the header Files. But I also have to link against the libary. But I dont know how to do so. I tried using something like this:

LIBS += -L /usr/local/qwt-6.1.0/lib -lqwt

但是比起我，我收到了一个名为找不到-lqwt的库"的错误.

But than I get an error called "libary not found for -lqwt".

我做错了什么? 如何链接到库或如何将qwt框架导入项目?

What I am doing wrong? How can I link against the library or how could I import the qwt framework into my project?

推荐答案

我找到了解决方案. 这是有关如何在Mac OS X下安装QWT 6.1.0并使它在QT-Creator中运行的逐步指南:

I found a solution. Here is a step by step guide on how to install QWT 6.1.0 under Mac OS X and get it running inside the QT-Creator :

从此处.tar.bz2 . > sourceforge/projects/qwt/files/qwt/6.1.0/

将其提取到所需位置，例如在下载文件夹中

然后转到目录 qwt-6.1.0

然后，您必须找到qmake命令行工具(可以通过在Finder中简单地搜索它来实现.

然后使用qmake qwt.pro文件，例如/Applications/QT/5.1.0/clang_64/bin/qmake qwt.pro

制作

sudo进行安装

在您的QT项目中，您必须将以下行添加到 .pro文件 include(/usr/local/qwt-6.1.0/features/qwt.prf) 将QWT库纳入Project

现在，您必须创建这样的软链接: sudo ln -s /usr/local/qwt-6.1.0/lib/qwt.framework/qwt/usr/lib/qwt

Download the .tar.bz2 from here sourceforge/projects/qwt/files/qwt/6.1.0/

Extract it where you want, for Example inside your Download-Folder

Then change into the directory qwt-6.1.0

Then you have to locate the qmake command line tool ( you can do so by simply searchng for it inside the Finder.

Then qmake the qwt.pro File like /Applications/QT/5.1.0/clang_64/bin/qmake qwt.pro

make

sudo make install

Inside your QT Project you have to add the following line to the .pro File include ( /usr/local/qwt-6.1.0/features/qwt.prf ) includes QWT libary into Project

Now you have to create a softlink like this : sudo ln -s /usr/local/qwt-6.1.0/lib/qwt.framework/qwt /usr/lib/qwt

就这样. QWT现在应该可以工作了.

Thats it. QWT now should work.

地下小牛:

如果您使用的是Mavericks，则必须手动将qwt.framework复制到Libary/Frameworks文件夹，以免出现"dyld:未加载库:libqwt.6.dylib"错误.

If you are using Mavericks you have to manually copy the qwt.framework to Libary/Frameworks folder for not getting the "dyld: Library not loaded: libqwt.6.dylib" error .. i dont know why but it works.
