odin-raylib-hot-reload-game-template's Issues

linux support

I have tried following your blog post on hot reloading, in linux, substituting .dll's for .so's where ever needed but I ran in to troubles and gave up.

Might try again soon.

Build release optimized for speed?

Shouldn't build_release be optimized for speed with -o:speed? Maybe also -strict-style.

From https://github.com/odin-lang/Odin/wiki/Compiler-Flags

• o:minimal: Set the optimization mode for compilation. Valid strings are minimal, size, speed

And from https://github.com/odin-lang/Odin/blob/76229cabfaf1f3fd973842b8e11e16c2e4e64896/src/main.cpp#L2000

print_usage_line(1, "-strict-style");
print_usage_line(2, "Errs on unneeded tokens, such as unneeded semicolons.");
print_usage_line(2, "Errs on missing trailing commas followed by a newline.");
print_usage_line(2, "Errs on deprecated syntax.");

I.e.:

odin build main_release -define:RAYLIB_SHARED=false -out:game_release.exe -no-bounds-check -subsystem:windows -o:speed -strict-style

qprocess can't be found while running build_hot_reload.bat

As the microsoft qprocess documentation page states, qprocess is only available in windows server

Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012

I'm running Windows 11, and as such, qprocess can't be found when running build_hot_reload.bat

I fixed this by applying this solution as follows, feel free to copy it, adapt it or find some other fix.

@echo off
SETLOCAL EnableExtensions

rem Build game.dll
odin build . -show-timings -use-separate-modules -define:RAYLIB_SHARED=true -build-mode:dll -out:game.dll -strict-style -vet-unused -vet-using-stmt -vet-using-param -vet-style -vet-semicolon -debug
IF %ERRORLEVEL% NEQ 0 exit /b 1

rem If game.exe already running: Then only compile game.dll and exit cleanly
set EXE=game.exe

FOR /F %%x IN ('tasklist /NH /FI "IMAGENAME eq %EXE%"') DO IF %%x == %EXE% goto ProcessFound

goto ProcessNotFound

:ProcessFound
exit /b 1

:ProcessNotFound

rem build game.exe
odin build main_hot_reload -use-separate-modules -out:game.exe -strict-style -vet-using-stmt -vet-using-param -vet-style -vet-semicolon -debug
IF %ERRORLEVEL% NEQ 0 exit /b 1

rem copy raylib.dll from odin folder to here
if not exist "raylib.dll" (
	echo "Please copy raylib.dll from <your_odin_compiler>/vendor/raylib/windows/raylib.dll to the same directory as game.exe"
	exit /b 1
)

exit /b 0
