I’ve compiled libsdl to render to the framebuffer in Linux [vesafb, linux
2.6.17] and things are fine… almost. All SDL apps I’ve tried [many of the
demos from libsdl.org site] wait for a ^C before they start any rendering.
I haven’t done lots of investigating, and I’d thought I would ask if this is a
known issue before hunting down the offending lines in the code [this happens
on over a dozen different SDL demos I have tried].

It sounds like the fbcon code is blocking on a device open. You could try
putting printf() statements in the SDL fbcon initialization code to see how
far it’s getting…
See ya!

Ah, printf(). That function has been single-handedly debugging my
applications since 1992.On 7/10/06, Sam Lantinga wrote:

I’ve seen this before it doesn’t happen on the first run of the app
which is why I never fixed it as i only run my apps once
but it seems to get stuck in a vt ioctl in SDL_fbevents.c, if you run
the app in a debugger, hit Ctrl-C and then bt you’ll see it.
