using Qwt with windows

[mesman00]

i should also note that i cannot execute the qwt examples. i get the following error:

The procedure entry point _Z5qFreePv could not be located in the dynamic link library QtCore4.dll

[mesman00]

ok. i've fixed the problem i posted in the second post by adding c:\Qt\4.4.3\bin as the first entry in my PATH variable. I do not know what that would make a difference. however, i am still experiencing the trouble posted in the first post.

ok i have fixed all my problems now. i had to add

INCLUDEPATH += C:\qwt-5.1.1\include
LIBS += C:\qwt-5.1.1\lib\qwt5.dll

to my project files. then since i had compiled qwt in release mode, i had to change my executable to release mode as well.

I have changed my Qwt compile parameters (in Visual C++) so that Debug mode builds "qwt5d.dll" and Release mode builds "qwt5.dll". This allows me to link my debug executables with a debug Qwt library and follow the debugger into Qwt if needed.

Since I convert Qt .pro files into Visual Studio projects, I don't know how to edit the .pro file directly to achieve this same output, but I'm sure it is possible.

yah i actually figured that out this morning. you can change the setting in the .pri file before compiling qwt to build both the debug and release dll's.

Hi mes,

What changes you did in .pri file to run the examples of Qwt.
