Can i use Libtorch library on QT Creator with qmake?

SGaist

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

Also, use forward slashes for paths. Qt handles the transformation to native path and it will avoid escaping issues.

QT Creator 4.8.2
MinGW 7.3.0 64 bit

I adjusted forward slashes for paths.

QT Creator 4.8.2

This is not Qt version...

"I adjusted forward slashes for paths." - and rerun qmake and rebuild?

Might be silly question but do you currently have a MinGW build of lib torch ?

mesut.toruk

QT 5.12.2.
No, i do not have MinGW build of lib torch. Then this post, i looked for it. It seems hard. They recommend using MSVC. I installed Visual Studio 2017 and tried to set compiler. I guess, I couldn't do it right. How can i add MSVC 2017 to Tools>Options>Kits>Compilers?

My error:

13:21:15: Could not determine which "make" command to run. Check the "make" step in the build configuration.
Error while building/deploying project t2 (kit: Desktop Qt 5.12.2 MSVC2017 64bit)
When executing step "qmake"

You cannot. Creator auto-detects it. Where did you install Visual Studio 2017? Did you install the C++ compiler too?

I installed C:/Program Files/Microsoft Visual Studio. I also installed C++ compiler. It is "cl.exe" in Visual Studio.

Hi @mesut.toruk,

I installed C:/Program Files/Microsoft Visual Studio. I also installed C++ compiler. It is "cl.exe" in Visual Studio.

And the compiler is not auto-detected in Tools > Options > Kits > Compilers ?

No it is not. Should Qt install MSVC? While i install QT, i marked MSVC. But there is no MSVC in C:\Qt\Tools. However, there is qmake in C:\Qt\5.12.2\msvc2017\bin. I installed externally Visual Studio and tried to add it. It gives error.

No, QtCreator should auto detect Microsoft C++ compiler. Can you show your compiler tab?
Which Visual Studio version did you install?

I installed Visual Studio 2017 and Visual Studio 2019.

@mesut.toruk The Microsoft compilers were not auto detected.
Did you install the C++ parts of Visual Studio (those are not automatically installed)?
If so, then try to deinstall QtCreator and install it again.
