Status?

[AregevDev]

Hi, I really appreciate this fork of nanogui. I prefer using SDL for my OpenGL development and this library is absolutely beautiful and suit my needs.

Is this fork still active? There is a commit from yesterday after a few years of inactivity...

Also, I tried to build it today from source, on Windows. It generally has many problems:

• Need to manually build SDL2 from source and specify the include and library directories. I suggest adding a submodule to the GitHub mirror of SDL2 and find a way to build SDL2TTF and SDL2_Image since they don't use CMake...

• Headers include SDL.h instead of SDL2/SDL.h

• Many compile errors with unresolved references, specifically SDL_FRect / FPoint. Not sure what they are.

• GLCanvas widget is missing. One the project builds again, it's worth implementing... It might be more complex though...

Please keep the hard work! Much appreciated. I will happily contribute to this project.

Best regards Alon

In develop, hope I have time now to support it I used cmake that create solution for vs Now it using nanort render, instead of opengl render, because SDL compatibility need Will fix readme with build instructions

[dalerank]

clone repo $mkdir build $cd build & cmake .. open solution in vs sory just may test in on windows 10 only yet

[AregevDev]

Thanks for replying, Which SDL version should I use when building? Does it support SDL 2.0.9?

[dalerank]

Yep, just downloaded stable from libsdl.org, seems it need again update install instructions for win

[AregevDev]

I am getting build errors when building the generated solution https://pastebin.com/D2X2YTPH Mind taking a look?

I am using SDL 2.0.9

[dalerank]

what '$build cmake ..' say?

[AregevDev]

[dalerank]

ouch.... $build cmake .. means run 'cmake ..' from folder build

[AregevDev]

That's what I do, it configured alright, but it fails to build

I use this configure command to detect the libraries:

cmake -DSDL2_LIBRARY="../../libs/x64-windows-static/lib" -DSDL2_INCLUDE_DIR="../../libs/x64-windows-static/include" -DSDL2TTF_LIBRARY="../../libs/x64-windows-static/lib" -DSDL2TTF_INCLUDE_DIR="../../libs/x64-windows-static/include" -DSDL2_IMAGE_LIBRARY="../../libs/x64-windows-static/lib" -DSDL2_IMAGE_INCLUDE_DIR="../../libs/x64-windows-static/include" ..

[dalerank]

will try you cmd line possible you need removed content from build folder and run your command again, because cmake may cached some variables? on my pc output was,

[AregevDev]

What's you output when you build: IE cmake --build .?

I deleted my build folder's contents, reconfigured again, it comes up with the same build errors

Which SDL version do you use, that's so strange for me...

[AregevDev]

Does nanogui-sdl depend on something, other than SDL, SDL image and SDL ttf?

[dalerank]

No other depends

[AregevDev]

Which SDL version do you use, that's so strange for me...

And the version?

[dalerank]

Last stable from libsdl.org 2.0.10

[AregevDev]

I rebuilt 2.0.10 this time, same errors. They are about undefined references SDL_FRect SDL_FPoint SDL_RenderFillRectF Do you know where they are from?

[dalerank]

It sdl2 structs

[AregevDev]

Are you sure? Does not seem like that

[dalerank]

sure, official sdl repo http://hg.libsdl.org/SDL/file/bc90ce38f1e2/include/SDL_rect.h look at line 88

created travis-ci for test building on windows it downloads stable sdl2 stuff from libsdl.org and unpack it after that build no errors

https://travis-ci.org/dalerank/nanogui-sdl/builds/582167397

[dalerank]

try now

[dalerank]

fixed
