sorry for the late response, there doesnt seem to be a separate package for my system, and in maybe im missing something but this seems right? also the proper .a/.so files |

I was in the middle of typing a response when you posted your last comment, where I was going to suggest you check those directories and yep, seems like everything is there. I'm noticing they are in It's not likely the cause of this particular issue, but you seem to have version 2.0.20 installed while our BUILDING.md indicates you need at least 2.0.22. It will probably be just fine, but if you do have any weird bugs that nobody can replicate later that could be the cause. |

as far as the update, i just checked and theres a new sdl2 version in ports, but the package repo doesn't seem updated, i'll look at building and installing that if i need to. and yes i don't honestly know if cmake checks those directories for files, but i assume since other projects work, and the openbsd package installs the cmake files to that directory, so i assume it would |

Oh and I should clarify, changing just that one line I mentioned may not make it configure successfully, but it should get rid of one of those two errors if that's what the issue was. |

No, it should be linking the library statically and thus should be looking for libSDL2.a I believe. And regardless I've got similarly weird names on Linux, although now that you bring it up I do see symlinks for names without those numbers on Linux. Hmmm, perhaps for BSD we need to be linking Thanks for your patience in testing thus far, I don't think anyone on the dev team has a BSD system ready to go, so you being willing to try my suggestions is a huge help. |

SDL2-static gives this no problem this is easy enough for me to test, honestly i attempted to get it working my self for awhile but i'm just not used to cmake like i am other build systems |

It looks like you changed line 2063, that should stay at just find_package(SDL2)
set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)
set(ADDITIONAL_LIBRARY_DEPENDENCIES
"libultraship;"
"ZAPDUtils;"
SDL2::SDL2-static #change this line
"$<$<BOOL:${BUILD_CROWD_CONTROL}>:SDL2_net::SDL2_net>"
${CMAKE_DL_LIBS}
Threads::Threads

Hmmm. I'm running out of ideas then. I'd say your next best bet is to see if you can build and install SDL2 2.0.22 or above. I haven't dug deep enough yet to say for certain, but there were definitely cmake changes between those two versions that might have an impact. |

Only SDL2::SDL2 is not found. https://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/devel/sdl2/patches/Attic/patch-sdl2-config_cmake_in?rev=1.4&content-type=text/plain&hideattic=1 shows a patch to add it. With this configuration works. |

modifying playing around with the extract assets phase now results in it not finding SDL.h no matter if i passed i guess this is where i should mention that i've been using https://github.com/michaelforney/samurai on my system for ninja builds, but it shouldn't be negatively effecting anything, and if it seems like it could i'll try regular ninja. if that patch does something special id like to know but actually cant figure out where or why its applied sdl2-config.cmake is literally just i assume this is prepatched when built for openbsd, honestly that might be the patch used on building the sdl2 package. |

I also reviewed the patch @th-2021 mentioned prior to building. The last time I ran into the ftruncate errors was when we were beginning the port for switch. At the time I had used a modified FileStream.cpp for StormLib. StormPort.h has some of the defines listed. Edit: Fixes the |

I believe OpenBSD uses clang by default now, so #3383 will be another step towards proper support. |

Hi all, I recently set up a VM running OpenBSD 7.4. I didn't run into any issues with SDL2 but CMake is having issues with the GL header files despite having included them. I haven't resorted to linking X11R6/include to usr/include yet but I might do so. I'm not really knowledgeable enough in CMake to understand why using FindOpenGL and target_include_directory isn't working despite FindOpenGL correctly identifying the include folder. X seems to have issues running in HyperV, I really don't have the patience to debug it right now. This certainly limit my helpfulness. |

Looks like you're trying to build with Clang, it must be built with GCC at the moment. I believe 7.4 has a new enough version, current hopefully has a newer one. Just tell cmake and ninja which compiler to use before running the build. You'll need to delete your build folder and restart. export CC=/usr/local/bin/egcc
export CXX=/usr/local/bin/eg++Modify to suit your system :) |

Also, thanks for the fix. I'm still scratching my head why it's necessary to add a global include like that. Off-topic, is there a kernel mod to enable SMT? I've already broken KARL on my VM. I do not care for the mitigations when they decrease performance. |
