I got a lot further with set(CMAKE_CXX_STANDARD 17) in CmakeLists.txt ... still hacking ☺

[trathborne]

Including algorithm, cmath, math.h, cstring in various places has whittled it down to: Source/LensFlares.cpp:53:12: error: a reinterpret_cast is not a constant expression ... return (RTGL1::ShIndirectDrawCommand *)((uint8_t*)pCullingInputBuffer + GetIndirectDrawCommandsOffset());

[trathborne]

https://github.com/MusicPlayerDaemon/MPD/commit/37b54179d882fef38ca6735b53e322027414b62e had the solution for that!

If this works for others, I'll make a PR: (or the author can just pull it!) https://github.com/trathborne/RayTracedGL1/tree/compile-on-ubuntu-20.04

[arrowgent]

alright let me give this a test

[arrowgent]

yep compiles without errors (dlss off because i dont have RTX card)

ubuntu 18.04

If this works for others, I'll make a PR: (or the author can just pull it!) https://github.com/trathborne/RayTracedGL1/tree/compile-on-ubuntu-20.04

just go ahead and make a PR. @trathborne good job

[arrowgent]

this PR would also close this: https://github.com/sultim-t/RayTracedGL1/issues/7

[arrowgent]

would have to be tested on a windows compiler also so that your changes doesnt break the windows end

[sultim-t]

That's nice :) First steps for Linux support, hehe (I will start looking next week)

[Civil]

would have to be tested on a windows compiler also so that your changes doesnt break the windows end

Here it's actually easier. Most of the changes that were done in the PR referenced are to make code conform with C++20 and they were either casting fixes or header fixes (adding missing headers that were indirectly included by MSVC). Most of the time they are safe. But of course this should be eventually tested under whatever MSVC version author uses.

[arrowgent]

current build https://github.com/sultim-t/RayTracedGL1/commit/fdca400fc055b90a1bb6aa3165230e57c16e81ca

compiled on linux with no complaints

[Jackfritt]

Ok i got it to compile. But when it runs I get a short window open then sound crack and exit. thats all... Any suggestions? I also added to file ~/.prboom-plus/prboom-plus.cfg exclusive_fullscreen=1

Then InitScreenResolution gets set to 640x480...
