CGAL Linking Error QT Creator Project for Windows and Linux

Hi,
i have Problems Creating Project on QT with CGAL and Boost on Windows 10. In this project there are a few .pro Files and all project without CGAL would be compiled. Boost also works without problems. If i would compile the CGAL Project i got Linking Errors:

Here is my .pro file

win32:INCLUDEPATH += C:/CGAL32/include/
win32:INCLUDEPATH += C:/CGAL32/build/include/
win32:INCLUDEPATH += C:/boost_lib_inc/include/
win32:INCLUDEPATH += C:/boost/boost_1_68_0/

win32:CONFIG(release, debug|release): LIBS += -LC:/CGAL32/auxiliary/gmp/lib -lgmp-10 -lmpfr-4 -LC:/CGAL32/build/lib/Release  -lCGAL-vc140-mt-4.12.1 -lCGAL_Core-vc140-mt-4.12.1
else:win32:CONFIG(debug, debug|release): LIBS += -LC:/CGAL32/auxiliary/gmp/lib -lgmp-10 -lmpfr-4 -LC:/CGAL32/build/lib/Debug -lCGAL-vc140-mt-gd-4.12.1 -lCGAL_Core-vc140-mt-gd-4.12.1
else:unix:!macx: LIBS += -L$$PWD/../../../../../../usr/lib/x86_64-linux-gnu/ -lCGAL

On Linux all works fine.

Hi and welcome to devnet,

What compiler are you using ?
What version of Qt are you using ?

@SGaist said in CGAL Linking Error QT Creator Project for Windows and Linux:

What compiler are you using ?
Desktop QT 5.9.5 MingW 32Bit (CGAL is installed with 32Bit)
What version of Qt are you using ?
5.9.5

SGaist · wrote on 17 Sept 2018, 21:10

Might be a silly question but is CGAL compiled also with MinGW ?

username1 · wrote on 18 Sept 2018, 06:30

Nope. CMake with Visual Studio because it did not work with MingW.
If i start the programm in QT with Visual Studio Compiler it also failed.

SGaist · wrote on 18 Sept 2018, 21:41

Do you have a Visual Studio built 32bit Qt installed on your system ?

[edit: added missing compiler SGaist]

That's the Qt Creator version, I'm asking about the Qt version(s) you installed.

You can't mix and match C++ compilers like that. Either you do go full Visual Studio or full MinGW but both are not compatible one with the other. Neither are the Visual Studio versions between except for VS2017 which is compatible with VS2015.

Our project is realized with QT but i can build CGAL only with Visual Studio in CMake.

Thats how the instruction of CGAL tells me:
I open CMake set the paths and click configure. Now i choose MingW and got a error "Error in configuration process, project files may be invalid"
I only can build CGAL with Visual Studio.
If i do that i get a .sln file which should be build in Debug and Realease mode in Visual Studio.

And now i have the salad :D zefix

@username1

if you compiled CGAL yourself, than you already have a MSVC Compiler on your system.

Find out what version you used (2012, 2015, 2017, 32bit or 64 bit, etc.) and use the MaintenanceTool of your QtCreator to download the precompiled MSVC Qt-libary.

QtCreator should auto setup a new kit for you.
Select the new kit, compile, and you're done.

I used Visual Studio 15 2017 in CMake.
In QT it was already installed.
New Kit selected. Compiled. Error.
Some errors qalgorithms.h
"...\qalgorithms.h:847: error: C3615: Die constexpr-Funktion "qCountLeadingZeroBits" darf keinen konstanten Ausdruck ergeben."

Did you install the 32bit Visual Studio build of Qt ?

username1 · wrote on 26 Sept 2018, 08:01

All Tools and Programs i used are installed in 32Bit

SGaist · wrote on 26 Sept 2018, 20:10

But again: Did you build everything using the same compiler ? And are you sure you are using the correct version of everything to build your application ?
