Go bindings for SDL

go-sdl's Issues

Oops.

Wrong project, please close.

Keysym's Unicode field is always 0

Problem:

Even when enabling unicode translation with sdl.EnableUNICODE(1) the Unicode field is always zero. It works fine using C SDL. This is on a 32 bit machine so hopefully nothing odd is going on.

Fix:

I can fix this by changing the struct to:

type Keysym struct {
    Scancode uint8
    Pad0     [3]byte
    Sym      byte
    Mod      byte
    Pad1     [5]byte
    Unicode  uint16
}

This inserts some more padding before the Unicode field. I can't really explain why this is needed but it seems it ends up on these bytes. At least for me.

NSInternalInconsistencyException creating window in test. OS X 10.6.6

Problem

When I run the GO-SDL test on OSX 10.6.6 I get a lot of errors about leaking objects due to no autorelease pool being in place, and then a crash trying to create the window.

Event parameters

The current event handling functions pass around a copy of a 24-bytes struct for each call, which should be avoided.

VideoInfo is wrong?

Compare the C struct with the Go one, they're entirely different.
The correct struct might be:

type VideoInfo struct {
  HW_available uint32 "Flag: Can you create hardware surfaces?"
  WM_available uint32 "Flag: Can you talk to a window manager?"
  UnusedBits1, UnusedBits2 uint32
  Blit_hw uint32      "Flag: Accelerated blits HW --> HW"
  Blit_hw_CC uint32   "Flag: Accelerated blits with Colorkey"
  Blit_hw_A uint32    "Flag: Accelerated blits with Alpha"
  Blit_sw uint32      "Flag: Accelerated blits SW --> HW"
  Blit_sw_CC uint32   "Flag: Accelerated blits with Colorkey"
  Blit_sw_A uint32    "Flag: Accelerated blits with Alpha"
  Blit_fill uint32    "Flag: Accelerated color fill"
  UnusedBits3 uint32
  Video_mem uint32   "The total amount of video memory (in K)"
  Vfmt *PixelFormat  "Value: The format of the video surface"
  Current_w int      "Value: The current video mode width"
  Current_H int      "Value: The current video mode height"
}

Fail to build

Just cloned the source (rev 8309d2a) and tried to build, but it fails immediatelly with following output:

gomake -C sdl

make: *** [all] Error 2

Compile error with "6g version weekly.2011-04-04 8085"

I got following errors with the weekly go version:

sdl.go:484[_obj/sdl.cgo1.go:487]: undefined: os.O_CREAT
sdl.go:488[_obj/sdl.cgo1.go:491]: undefined: os.O_CREAT
sdl.go:490[_obj/sdl.cgo1.go:493]: undefined: os.O_CREAT

If I changed "os.O_CREAT" to "os.O_CREATE" then it compiles.

Update to newer go version

With latest stable go one can not build Go-SDL

Issue with Goinstall

Hi sorry if this is my fault, but I guess it might help someone else looking here.

I followed the new readme (and the old one) and I have had quite a few issues. I now have it down to one.

My go version is compatible with weekly.2011-12-14 (i know because I installed this version)

I have all the SDL parts and they all work with other languages
GOPATH=/home/me/gocode
GOROOT=/home/me/go
PATH=$PATH:/home/me/go/bin


When I run goinstall github.com/banthar/Go-SDL/sdl I get some permission denied error (not too sure why meh)

so I run sudo -E goinstall github.com/banthar/Go-SDL/sdl
and get
/bin/bash: === cd /home/me/gocode/src/github.com/banthar/Go-SDL/sdl; bash gomake -f- install
8g -I "/home/me/go/pkg/linux_386" -I "/home/me/gocode/pkg/linux_386" -p github.com/banthar/Go-SDL/sdl -o go.8 constants.go structs_386.go _obj/sdl.cgo1.go _obj/_cgo_gotypes.go

make: *** [go.8] Error 1

Just not too sure what this error means

On Windows "Package sdl was not found in the pkg-config search path."

Well I have to build a program using SDL and Golang on Windows. This is what just happened when I ran "go get github.com/banthar/sdl" in Git Bash.

$ go get github.com/banthar/Go-SDL/sdl

C:\TDM-GCC-32\bin\pkg-config.exe --cflags sdl

Package sdl was not found in the pkg-config search path.
Perhaps you should add the directory containing `sdl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'sdl' found
C:\TDM-GCC-32\bin\pkg-config.exe: exit status 1

Unfortunately I googled and found that "pkg-config" is unavailable on Windows. And the SDL don't provide a file named "sdl.pc". Maybe your library is just available on other platforms?

Flags for SetVideoMode should be uint32 instead of int.

A couple of the automatically generated constants have int type, this causes issues because some of them overflow int when combined and SetVideoMode only takes uint32.
I suggest we identify all possible flags for that function and type them properly.

Build failure on 64 bit linux

Building Go-SDL fails consistently on my machine. Even after updating Go to the latest release and making sure all requirements are met (sdl libs).

The following are the errors I get when make hits the sdl package:

sdl.go:49[sdl.cgo1.go:51]: VideoInfo redeclared in this block previous declaration at constants.6.go:397
sdl.go:66[sdl.cgo1.go:68]: undefined: internalVideoInfo

After some digging, I found that the problem is in the auto-generation of the constant.6.go file.
The internalVideoInfo struct is supposed to be generated in this file, but it is only present in the constants.8.go file. Not in the constants.6.go file (which is my arch).

the 6.go file contains a (duplicate) 'VideoInfo' struct:

type VideoInfo struct {
    Pad0        [2]byte
    UnusedBits3 uint16
    Video_mem   uint32
    Vfmt        *PixelFormat
    Current_w   int32
    Current_h   int32
}

Where it should be having:

type internalVideoInfo struct {
    Flags     uint32
    Video_mem uint32
    Vfmt      *PixelFormat
    Current_w int32
    Current_h int32
}

Manually replacing it fixes the problem and the build works as intended, but I thought I'd mention it here so it can be addressed.

RW functions

Any plans to wrap them? They can be very useful at times.
For instance, it'd be great to have IMG_Load_RW (to display an image I deflate into memory) --with IMG_Load, I am forced to write a copy of it on filesystem first.

Add SDL_mixer effects for things like positional sound

http://www.libsdl.org/projects/SDL_mixer/docs/SDL_mixer_75.html#SEC75

or at least the built in mix processors:
Mix_SetPanning
Mix_SetDistance
Mix_SetPosition
Mix_SetReverseStereo

Included test program crashes on startup (OSX)

Go-SDL compiles without a hitch (after installing SDL with brew) and so does the test program, but it crashes instantly with tons of output. See here:

http://pastebin.com/ARyuE7pY

Does Go-SDL work with the go command?

or did I miss something?

go get github.com/banthar/Go-SDL/sdl

pkg-config --cflags sdl

exec: "pkg-config": executable file not found in $PATH

on a mac

Unlock flips the buffer

In sdl/sdl.go, the method *Surface.Unlock should call SDL_UnlockSurface instead of SDL_Flip, which it currently does.

Problem with ttf/Makefile on Mac OS X.

On my Mac OS X 10.6 system the ttf module does not get compiled because there is a space between -L and the path specification in the Makefile for LDFLAGS. Removing the space fixed the problem for me.

test-sdl prints "unknown key" every time I press a key.

Every time I press a key in the SDL test "unknown key" is printed. The test prints out the mouse information just fine, though.

I'm using SDL version 1.2.13 on Linux (Ubuntu Karmic, kernel 2.6.31-15)

License?

Please specify a license for your project so users will know the terms they are allow to use and redistribute Go-SDL.

If you simply don't want to be inconvenienced by adding license headers to the tops of your files, I have a small utility for handling that here: https://github.com/gtalent/Liccor

[fyi] go-sdl-example

Hi,

This isn't really a feature request, nor a bug, but in case you wanted to know, here's the SDL example for Go-SDL, packaged separately for Arch Linux. It includes an application shortcut and could possibly be used as an example for packaging other games and applications that are using Go-SDL.

Best regards,

PushEvent

cEvent() causes panic with panic: reflect.Value.UnsafeAddr of unaddressable value.. One can simply try pushing a UserEvent to get this.

Fail to compile with Go release 2010-07-14

I've got an issue trying to compile the package with latest Go release:

andrea@ganimoide:~/src/Go-SDL$ make
make -C sdl install
make[1]: ingresso nella directory «/home/andrea/src/Go-SDL/sdl»
CGOPKGPATH= /home/andrea/bin/cgo `pkg-config --cflags sdl` sdl.go
flag provided but not defined: -D_GNU_SOURCE
usage: cgo [compiler options] file.go ...
make[1]: *** [_cgo_defun.c] Errore 2
make[1]: uscita dalla directory «/home/andrea/src/Go-SDL/sdl»
make: *** [install] Errore 2

Can't compile with latest Go release

End of make output:

CGOPKGPATH= cgo -- `pkg-config --cflags sdl` sdl.go
8g -o _go_.8 constants.go structs.8.go sdl.cgo1.go _cgo_gotypes.go

[etc]

"Package SDL_ttf was not found in the pkg-config search path."

The output of calling make:

gomake -C sdl
make[1]: Entering directory `/root/Go-SDL/sdl'
make[1]: Leaving directory `/root/Go-SDL/sdl'
gomake -C ttf
make[1]: Entering directory `/root/Go-SDL/ttf'
CGOPKGPATH=sdl cgo --  ttf.go
Package SDL_ttf was not found in the pkg-config search path.
Perhaps you should add the directory containing `SDL_ttf.pc'
to the PKG_CONFIG_PATH environment variable
No package 'SDL_ttf' found
ttf.go: bad #cgo option pkg-config: pkg-config failed
make[1]: *** [_obj/_cgo_run] Error 2
make[1]: Leaving directory `/root/Go-SDL/ttf'
make: *** [all] Error 2

I do have libsdl-ttf-dev installed.
I do not have the file SDL_ttf.pc anywhere on my only hard drive.
I do not know why it's happening to me.

which fork should i use?

this repository seems to be unactive for two years, and there are 74 forks, but i don't know which to choose. Which is best?

Missing stuff

Hi,
This's the list of stuff I found missing in the library. There're just the ones I bumped into though, I haven't made a real check.
SDL_INIT_TIMER definition is missing

RenderUTF8() is missing in SDL_ttf

Bunch of unresolved names when building

Riddle me this: http://pastebin.com/Jc5wEdwu

I ran gofix over all source files (wouldn't even get that far without it) and went through all makefiles, removed the pkg-config stuff and added -Ia:/mingw/msys/1.0/include to CFLAGS and -La:/mingw/msys/1.0/lib to LDFLAGS.

I have not made any further changes. Any idea what the issue could be?

Outdated Install Instructions?

Here (Arch Linux), I don't have goinstall, so I did:

go get github.com/banthar/Go-SDL/{sdl,ttf,gfx,mixer} 

(The test program works fine.)

ActiveEvent and ResizeEvent

Just so I don't forget, there are a couple more, but that's what I needed right now:

// Returns ActiveEvent or nil if event has other type
func (event *Event) Active() *ActiveEvent {
  if event.Type == ACTIVEEVENT {
    return (*ActiveEvent)(cast(event))
  }

  return nil
}

// Returns ResizeEvent or nil if event has other type
func (event *Event) Resize() *ResizeEvent {
  if event.Type == VIDEORESIZE {
    return (*ResizeEvent)(cast(event))
  }

  return nil
}
