Russian Qt Forum

Пытаюсь скомпилировать пример из QCA
qt-sdk-win-opensource-2009.01.1.exe установлен по умолчанию. все либы QCA подкинул в стандартные каталоги, кроме этого выполнил батник шедший с дистрибутивом.

Что сделать что бы увидел линкер либы?

почему -lqcad а не -lqcad2  ?????

убрал 2-ку в имени библиотеки заработало.
почему с именем файла (...от поставщика) не работает?

I'm sorry that my Russian is not fine to answer you in Russian. I'm not sure if you solved the problem already but will post the solution for all other people having the same problem like you. I had the same issue.

The problem is that the configure.exe doesn't create the debug files by default.
By default only "release compile"  will work.

If you want that debug will also be supported run
configure.exe --debug-and-release

Then
mingw32-make

Now check the lib directory.

As you can see it created:

qcad2.dll
qca2.dll
libqcad2.a
libqca2.a

Finally compile works fine.
Hope that I could help you.
