@Dario Ok so for qmake you would do something like:

LIBS += -L/path/to/libs -lwhatever

You can add multiple -Lpath and multiple -llib items. Keep in mind if a library name is something like libmylibrary.so then the corresponding -l command is -lmylibrary, you do not add the lib prefix or the .so suffix. Likewise if it was libsomething.a it would be -lsomething.

@Mohamed-Fouzi You should use the command prompt from your Visual Studio installation (you can find it in the Start menu).

Hi and welcome to devnet,

If possible you should update your installation. The current version of Qt Creator is 4.2.1 and 4.3 is around the corner.

No you shouldn't, what I meant and that wasn't clear was whether you ran a different qmake than the one you used to build the module since you seem to have called make install several times.

Thank you both !

Alex

@Alexander-9 As I said: my assumption is that the float ABI must be the same. You cannot mix binaries with different ABIs.

On a side note for people coming here: <full_path_to_qml_files_folder> means path to the project qml files folder.

said in Compilation of Qt 5.8.1 fails:

qqmltypeloader.cpp

I found a workaround. You have to add '#include' line to fix this problem.
In file .../qtdeclarative/src/qml/qml/qqmltypeloader.cpp, at line number 67:

#include <QtCore/qcryptographichash.h>

Strange, i'd check if the Windows SDK is installed.

@Technologist
Which python and mingw version do you use?

Thank you, problem solved.

Hi and welcome to devnet,

Please use the search function from the forum. This question has been asked and answered many times already. You are missing the OpenGL development libraries from your distribution.

You're welcome !

Since you have it working now, please mark the thread as solved using the "Topic Tools" button so that other forum users may know a solution has been found :)

but the address is not the one you insert and clean the with make clean.

@kickoune103 said in error after start example qt5.8 for raspberrypi:

-v it's use before.

Then please post the actual configure output (at least the part where fontconfig is being tested).

@Masonsu Good to hear this is fixed. And your english is great. :)

Great! Thanks for sharing your solution!

I tried turning QT off and on. Seems like nothing has changed. Yet while I was doing it I found another bug, seems when variable name is large enough there is no rectangle overlay, but it gets better, now QT show this hint window only once per debug session and then it's gone for good.

About timeline of this bug: I installed Ubuntu about half of hour ago from original .ISO file and tried to do as less as possible so nothing gets messed up...

Brilliant! I blew away my old release directory, recompiled from scratch, was careful to run the deploy tool from the 5.8 directory, and copied those three DLLs, and I'm in business, it runs! Thanks a ton for your assistance, both here and in your blog posts.
