Qt Creator and Stellarium-master

[astromout]

Hi,

I'm happy to be here...I tried scripts on stellarium. It works well.

But now I wanted to get a kind of "virtual desktop" in such away as to have "the public viewer" on a screen (videoprojector) and the "chief viewer" on my screen.

So, I want to put my hand in stellarium's code...
I downloaded stellarium-master.
I work with Qt-creator.
But, I have these errors :
CMake Error at CMakeLists.txt:18 (PROJECT):
The CMAKE_C_COMPILER:

cl

is not a full path and was not found in the PATH.

To use the JOM generator with Visual C++, cmake must be run from a shell
that can use the compiler cl from the command line. This environment is
unable to invoke the cl compiler. To fix this problem, run cmake from the
Visual Studio Command Prompt (vcvarsall.bat).

Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

CMake Error at CMakeLists.txt:18 (PROJECT):
The CMAKE_CXX_COMPILER:

cl

is not a full path and was not found in the PATH.

To use the JOM generator with Visual C++, cmake must be run from a shell

...

I read lot's of thing on internet around this error, but I'm like a chicken in front of a knife.
Help!!
Regards.
Franck.

Have you read the BUILDING.md instructions?

For your original problem, you can use SPOUT output to your projector, or use the RemoteControl HTTP interface.

Hi,
Thank you so much for helping...Thanks to you, I looked à BUILDING.md instructions and tried.
A priori, PATHS are ok (like in building.md), cmake (3.19.2),
Some errors appeared even in command line. They came at the end of compilation

Here are they:

Please try disable Telescope Control plugin in CMakeLists.txt file

[astromout]

I will try this, but, this morning, we compile fine and stellarium.exe was created.
After we tried to build with Qt Created and...errors appeared.

[astromout]

Hi,
I tried without Telescope Control plugin in CMakelists.txt and it compiles! Thank you so much.
In cmd, I just have some warnigs (in yellow). For example :

C:\Program Files (x86)\Windows Kits\10\Include\10.0.19041.0\um\winbase.h(9531,5): warning C5105: l'expansion de macro produisant 'defined' a un comportement indéfini (compilation du fichier source C:\Stellarium

• Are these warnings are important?

• When I launch stellarium.exe, my computer tells me SpoutLibrary.dll is missing...so I copy it in stellarium.exe folder and it works.

[astromout]

Hi,

Stellarium runs with cmd and with Qt Creator ❤️
I'm so happy! Thank you for your help...

Is it hard to have the step to get Telescope Control working ?

[gzotti]

Not sure. For me it worked out of the box on 5 Windows and 2 Ubuntu systems. Obstacles should be described in the BUILDING.md.

[astromout]

OK,
I have so much things to understand...Telescope Control will wait.

[astromout]

Parentheses : I play the RemoteControl HTTP interface. It is a fabulous plugin, exactly what I want...Of course, I will try to add things on it as soon as I'll be able to compile.
