Do you have XQuartz installed? On Apr 16, 2013 12:25 PM, "Zhuang Ya" notifications@github.com wrote:

When you ran go get you set the proper path for pkgconfig?

This is an issue I've come across before. It's just a matter of making sure you told go get where to find SDL.

[zhuangya]

@scottferg hmm... that's strange.

i just follow your instruction to install, and here is some output related:

check this gist

is there anything wrong?

[pusewicz]

I'm having exactly the same issue.

This issue is open here, too btw https://github.com/0xe2-0x9a-0x9b/Go-SDL/issues/16

[KTamas]

Same here.

So I used to experience this issue frequently and it was always a case of go get looking in the seemingly wrong place. Two things that I've done that got around it:

1. I installed SDL manually from source (http://www.libsdl.org/release/SDL-1.2.15.tar.gz) and pointed PKG_CONFIG_PATH to that
2. Installed from brew as the README suggests and pointed the PKG_CONFIG_PATH there

Currently on my OSX machine, which I've been using the past few months as the primary devbox for this project, I don't have or need any PKG_CONFIG_PATH set when I run go get, even from a clean build where I've zapped the pkg/ and relevant src/ dirs from my GOPATH. I do, however, remember go getting SDL and friends manually once, and setting PKG_CONFIG_PATH to the relevant .pc directories setup by brew, and I think that may be the issue you guys are seeing.

Something like: PKG_CONFIG_PATH=/usr/local/Cellar/sdl/1.2.15/lib/pkgconfig go get github.com/scottferg/Go-SDL/sdl

With regards to the bug report @mtrotzinski noted, I have come across that culprit as well but like I said, I've always fixed this particular error by making sure I was building the SDL bindings properly. I do see this problem show up here though: https://github.com/0xe2-0x9a-0x9b/Go-SDL/issues/7

What's weird with that one is that I never see it on Go 1.0.3. When I compile with Go 1.1 I see it intermittently, and simply retrying to run the emulator eventually works

It's entirely possible that the README is just incorrect and I set something up way back when and totally forgot what it was. I'll try on a fresh machine later and see if I can nail down the exact process.

I found a way to fix this issue: edit the brew recipe for sdl ($brew edit sdl) and remove the line that says "args << '--without-x'". After that you can reinstall sdl and everything should work fine!

[scottferg]

Nice find!

[ghost]

i noticed that it compiles with this flag when i reinstalled sdl several times without success. But i am still wondering if it is possible to make Go-SDL use quartz instead of x

[scottferg]

I force the SDL driver to x11 in Go-SDL/sdl/sdl_darwin.go in the event that SDL_VIDEODRIVER isn't set, so that may be a means of doing it.

[zhuangya]

i tried @mtrotzinski 's method, and it works ;)

i'm wondering, should we edit sdl's brew for the " --with-x " parameter.

[sugarsync-eisnerguy1]

I'm still having this issue

[scottferg]

Did you try the above solution?

[scottferg]

After successfully getting this installed and running on a handful of Macs using @mtrotzinski 's solution, I've added it to the README. Closing this issue.
