Qwt移植到天嵌qt4.5 arm版中不成功。x86移植成功。有人知道如何移植Qwt吗

麻烦天嵌的技术员不要那么现实。不关你们开发板的帖子都不给回复。

呵呵，我想楼主应该是误解了，论坛是用来相互交流讨论和学习的，并不是任何问题都在这个上面能得到完美的答案，天嵌论坛的帖子天嵌的技术支持都有时刻关注和顶贴的，只不过关于板子的问题熟悉些就顶贴多点，你的QWt是编译不过还是运行不起来呢，建议多贴点信息可能顶贴的人多点。

大哥 我的qq是7152471 能加我下吗？一起研究 在电脑上能运行qwt的例子了，可是我还不知道怎么能移植到板子上呢 一起研究下吧~~

我也在弄qwt，一个多礼拜了，没进展，用的是qt4.5

你好，请问是怎么操作在X86移植成功的？我的ARM，X86都没成功，我是进入QWT目录，然后，qmake,make ,make 时有问题？ qwt-6.1-rc3]# make

亲，不要同一个问题发多个帖子，浪费大家的时间。
你这个帖子的信息比较齐全了。
你检查一下你的arm版本的配置单中有没有添加qsvg相关的配置选项。如果没有，请添加上重新编译qt4库。

编译成功了，可是在开板上运行不显示qwt的示例程序，论坛上也出现这个问题，不知如何解决？

解决了吗？我也遇到这个问题

我的做法是把qwt-arm文件夹下的lib文件拷贝到/Linux+QT/文件夹下的lib中，通过生成镜像的方式解决此问题了
