Luxcore build error

[Luxart]

Hi,
I tried building Luxcore based on the instructions in GitHub (WindowsCompile).
I got the following error.

VS 2017 community edition is installed in my computer.
Any help is greatly appreciated .

Hi, it seems that for some reason cmake cannot find a C/C++ compiler.
Could it be that you have installed Visual Studio, but without selecting C/C++ development components?
You could try to run the installer again and verify that something like "Desktop development with C++" is selected.

[Luxart]

Windows Desktop application in Visual C++ is installed.

Previously, I was adding source files directly to the VS IDE, and build pyluxcore from it (as I need to change some source files according to my needs).
But from version 2.1 the OpenCL code are moved to .cl files. The .cl files are converted to .cpp files during the preprocess section of the build process.
So I just run the build process to collect the opencl files in .cpp fomat and use it in my VS project.

I think the below two files are mainly involved in generating .cl to .cpp files.

\luxcorerender\LuxCore\cmake\KernelPreprocess
\luxcorerender\LuxCore\cmake\Scripts\PreprocessKernel

I don't know how to use cmake and batch scripts.

Could you please provide me a batch script just to convert the .cl files in .cpp format, so that i don't need to run the entire build process and don't worry about the above error. Thanks .

Fix the real problem, don't do additional work to just work around. There must be a reason why for you (and only for you) cmake does't detect VisualC++: https://stackoverflow.com/questions/516 ... ual-studio

I agree, and the most likely solution is in the link posted by Dade.
Once that works, the easiest way to generate the files you need is:

Code: Select all

cmake-build-x64.bat /cmake-only

This will run only the cmake preprocessing, including generation of VS solution and kernel CPP files, without running the actual build.

Yes, After installing the "Visual C++ tools for CMake" feature, the kernel files are generated and all source files are compiled.

But, got this error after object files are generated

I got the required Kernel files for my project. So I can skip the rest of build process (no problem). But if the error can be corrected, let me know so that I can correct that too.

Thanks for the info Dade and acasta69 .

I may have had the same MSB6006 error.
Then i had to redo this:

pip install pyinstaller
press enter

pip install PySide2
press enter

pip install numpy
press enter
---------------
EDIT
If you have nVidia GPU, then CUDA toolkit has to be installed.

[acasta69]

I'm glad it's working now.

But if the error can be corrected, let me know so that I can correct that too.

Do you have a working Python3 with PySide2 also installed?
If not, that's the most likely cause: the pyluxcoretools cmake script deletes some files in order to regenerate them with the available PySide version. If PySide is not found, these files will be missing.

Anyway, you only need this if you want to have working pyluxcoretools.
All other binaries should have been built correctly.
