Ubuntu 10.04 LTS Lucid Lynx qwt 中的 QDevelop Qt IDE

Question

我在 Ubuntu 10.04 LTS Lucid Lynx 中使用 QDevelop、Qt IDE（Qt 版本 4.6.2）时遇到问题。我尝试使用的代码已从较新的 64 位笔记本电脑转移到我的 32 位笔记本电脑。两个系统都运行相同版本的 Ubuntu 和 Qt IDE。当我尝试构建代码时，我收到一长串错误，我不想在这里发布，但我会在文本末尾发布。任何帮助将不胜感激。不管出于什么原因，我的文本块被切断了。我正在使用“

在此处插入文本空白保留技巧，我做错了什么？好吧，我的构建文本块没有使用 prelashpre html 东西正确格式化。这篇文章的格式一切都搞砸了！:|

我发送给我的大学的电子邮件：

I installed the 32bit version of qwt-5.2.1 and it still isn’t building, I get the same errors. 

Attached are my .pro and make files as well as buildoutput.txt showing the results of my build.

See if you see anything wrong with any of the information below:

Checking paths:

In the myPico.pro file there is a line: LIBS += -L/usr/local/qwt-5.2.1/lib -lqwt-qt4 (This is 32bit, I found you can type “file” then space and a file name, it will give you information about the file including if it’s 32bit or 64bit. See note below.)

Inside /usr/local/qwt-5.2.1/lib I have three items that are teal: libqwt.so, libqwt.so.5 and libqwt.so.5.2 and one green item: libqwt.so.5.2.1. They all point to libqwt.so.5.2.1 and it’s 32bit.

Inside the Makefile, the line INCPATH everything seems ok, but I don’t understand the last part of the line: “-I/usr/include/qt4 -Ibuild  -Ibuild” When I go to /usr/include/qt4 I don’t see anything that says build. Could this be an issue?

In searching the web for solutions I see a lot of people having the same issue but their solutions are cryptic/Band-Aid short cuts.

Note: I thought of a possible issue. You had me copy the libs from your system and then we found out they were 64 bit. I installed the 32 bit ones but I don’t know if that removed what we copied manually. So I am trying to figure out where we copied those libs to. Ok I found it (/usr/local/qwt-5.2.1/lib) and they’re 32 bit, so installing the 32 bit overwrote the 64bit versions.

呃，很神秘的是，我什么也没做，问题就出现了，然后就消失了。
