Error running the program

[AzadKshitij]

When I was trying to run the program I'm getting this error 👇👇👇

My Project Structure is like this..👇👇👇

[ThakeeNathees]

The master branch is currently unstable and going through a heavy refactoring, and everything will be ported to https://github.com/ThakeeNathees/PixelEngine/tree/dev branch (a more stable and well organized)

I'll have a look at this issue, and Thanks for reporting :)

Sorry for this silly question but How can I use This branch for development of this engine and to understand the code?? 😅😅😅

@AzadKshitij I used to write the engine in SFML before and now I've moved to OpenGL 3.3 core profile (the low level graphics api) and have write a build system with Scons

How to compile?

All you need is Scons a python based build system. To install Scons you have to run the following command

python -m pip install scons

Now run the following command to compile the engine.

C:\PixelEngine> scons platform=windows vsproj=true

From the argument vsproj=true it'll generate Visual Studio project files, argument platform is optional and will be used for cross compilation since it'll support cross platform.

Now It'll build bin/PixelEngine.exe an Opengl implementation of ImGui window. If anything goes wrong let me know.

Next?

I'll move everything from the master branch to the dev branch with cross platform/language support, well organized and clean code base.

@ThakeeNathees I have done all what you said but I ran into some error ..

What compiler you're using, scons version?
If you have MSVC try running MSVC from command line check cl command works. If not add C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.26.28801\bin\Hostx64\x64 (might change in your pc) to PATH variable and re-compile. I haven't configured scons to search for MSVC yet. and let me know it worked.

[AzadKshitij]

I'm using scons version 47.1.0
before adding cl in path I was getting 'cl' not found error after the path was set I'm getting this error.

if you have Cygwin in your path try removing it. (related issue : https://community.intel.com/t5/Intel-Fortran-Compiler/link-problem-with-cygwin/td-p/784096)
if it's not working try this and re-compile

yeah!! it worked 😀😀😀😀
