using opc ua in qt

Mogli123

When I try to run:

cmake -DCMAKE_BUILD_TYPE = Share -G "MinGW Makefiles" -DUA_ENABLE_AMALGAMATION = ON -DCMAKE_INSTALL_PREFIX = c: \ Qt_5_12_MinGW \ open62541\build ..

I get the following error:
CMake error: The source directory "c: Qt_5_12_MinGW / open62541 / build" is not against containing CMakeLists.txt.

I run this code in the build folder like in the discripiton.
I have installed MinGW64
is this a problem?

What am I doing wrong?

hi,
I have the 2 dots allready in my code like in my post above

When I run:

cmake -DCMAKE_BUILD_TYPE=Release -G "MinGW Makefiles" -DUA_ENABLE_AMALGAMATION=ON -DCMAKE_INSTALL_PREFIX=c:\path\to\open62541-mingw-install ..

I get this error:

CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles" CMake_Make_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles" CMake_Make_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage

I have no experience to work with the shell therefore I have no idea what I can do to solve the error.

@LeLev
thank you :)
adding links to the system path solved the problem

but now I have a building problem with

mingw32-make

error:

cc1.exe: error: unrecognized command line option "-Wpedantic"
cc1.exe: warnings being treated as errors
cc1.exe: error:unrecognized command line option "-Wno-static-in-inline"
...

if one error is solved the next one will follow:(

@Mogli123
Can you please check your mingw version ? with mingw32-make -ver

i used mingw that comes with qt, adding this to system path

C:\Qt\5.12.0\mingw73_64\bin

@LeLev
Thank you very much for taking the time to help me

I'm using mingw from qt, too.

my mingw version is:
GNU Make 4.2.1
Cuilt for x86_64-w64-mingw32
Copyright....

I add the same as you to the system path

@Mogli123 when you call cmake .. see if your output is ~similar to mine
maybe you need to update gcc

cmake -DCMAKE_BUILD_TYPE=Release -G "MinGW Makefiles" -DUA_ENABLE_AMALGAMATION=ON ..

@LeLev

I delet the fils in the build folder

try cmake again and all works fine

I don't know why....

THANK you very much for your helping

that is now qopcua 5.12?
Should I load the 5.11 version, because you noticed that the 5.12 does not work for you?

@Mogli123 right click on your cloned qtopcua folder> TortoiseGit > Show log to see the version.

Please try to build the qtopcua 5.12 and tell me if it works for you.

qmake c:\users\lev\Documents\LIB\qtopcua -- OPEN62541_PREFIX=c:\users\lev\document
s\lib\open62541 OPEN62541_INCDIR=c:\users\lev\documents\lib\open62541\build OPEN62541_LIBDIR=c:\users\lev\documents\lib\open62541\bu
ild\bin
mingw32-make
mingw32-make install

@Mogli123 said in using opc ua in qt:

howe can I test if it works?

create a project, a class, include <QtOpcUa> , create QScopedPointer<QOpcUaClient> m_client; , compile
