is it only about v fmt -w . ?

larpon · 2023-01-15T17:53:14Z

No it's about application design and how to extend vab without building special case support into the app for every framework available out there. A compile time plugin system would be gold - but maybe runtime plugin support would be okay as well. vab also miss some essential features from the v_sdl4android project.

JalonSolov · 2023-01-15T18:06:17Z

... but yes, the failing CI check is because the files need to be formatted with v fmt.

android/compile.v

+		src_path := os.join_path(raylib_path, 'src')
+		ndk_path := ndk.root()
+		os.execute('make -C ${src_path} clean')
+		arch_name := if arch == 'arm64-v8a' {


would it be more eficient and nicer with mach{...} instead of if ... else if ... else?

It would look cleaner with match. The else branch for the match would take care of the following if as well.

MatejMagat305 · 2023-03-18T19:18:39Z

android/compile.v

+
+			// add the compiled raylib libraries for each arch
+			if is_raylib {
+				build_cmd << '-L ${lflags}'


maybe initialisation of 'lflags' for raylib would be nice put inside if

Just to refresh what is going on here: I'm keeping this PR open because I think vab should support (.. or have better support for) compilation and packaging of user projects.

Work has been done lately to simplify calling and using vab as a module which is currently the most feasible and flexible way to get support for thirdparty projects into vab. Support should come, it just takes time.

MatejMagat305 · 2025-05-11T16:12:39Z

I was copy and done (with vlang/raylib#18) own version of this pr, can I give here or should I open other one? And I asume that is suitable all command put into vab, I will put prototypes and I asume you will tidy(give me point), it is ok?

I would prefer raylib support is done like SDL is supported; via an extra command like vab-sdl https://github.com/larpon/vab-sdl ... this way we can keep vab free of all the special cases that the different libraries uses in the build and package process etc.

The extra command should thus result in the user being able to build an application importing vlang/raylib with something like: vab raylib ...

I have it on https://github.com/MatejMagat305/vab-raylib, It compile lib, start compile .so, create .apk, but apk is without .so, I do know find error ..........,
here is raylib which belong to vab-raylib: https://github.com/MatejMagat305/raylib/pull/1/files
here is working vab: https://github.com/vlang/vab/pull/338/files
here is working raylib with this vab: https://github.com/vlang/raylib/pull/18/files

vab is working with manual :

I will take a look as soon as possible. I am a bit busy IRL at the moment 👍

ok, I will search for error, but I am probable at the end of my ability/skills and I do not want end without giving you report at least prototype .......

larpon · 2025-05-14T14:01:30Z

If the .so is not picked up it may be a directory structure problem or similar see the --libs flag, and https://github.com/vlang/vab/blob/master/docs/FAQ.md#i-managed-to-compile-some-external-so-libs-how-do-I-include-them

(--libs can be used programatically as well)

larpon · 2025-05-14T15:44:21Z

Ok. I've tried now to build the project. IMO both vlang/raylib and raysan5/raylib is extremely messy in the way everything is setup to work. I'll have to set aside some more time to investigate this.

larpon · 2025-05-14T18:12:27Z

@MatejMagat305 I have opened MatejMagat305/vab-raylib#1 to fix it so make works. But I'm getting some other error that hints that the dreadful raylib/raylib directory setup might be causing confusion.

@MatejMagat305 this is because libraylib.a is never used by the NDK compiler. If you run vab-raylib with -v 3 you can see in the output from clang that it ignores -l:raylib etc.
I think the linking is done in the wrong stage of building.

I am working on a solution that is not forked from larpon/vab-sdl that compiles raylib in parallel directly instead and does not depend on make and git .

larpon · 2025-05-24T14:15:33Z

I am closing this. Use https://github.com/larpon/vab-raylib to build vlang/raylib based apps for Android.
