Bug 271

Summary: autoconf incorrectly tests for fbcon support
Product: SDL Reporter: Sean D'Epagnier <spdepagn>
Component: buildAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED WORKSFORME QA Contact: Sam Lantinga <slouken>
Severity: major    
Priority: P2    
Version: HG 1.2   
Hardware: All   
OS: Linux   

Description Sean D'Epagnier 2006-07-02 05:31:46 UTC 
Hi, I ran the configure script and it did not detect support for fbcon, when in fact my system supports it.

I know the exact fix, it is a change in configure.in, on line 1112, should be changed to:

        AC_TRY_COMPILE([
         #include <linux/fb.h>
         #include <linux/kd.h>
         ],[ ...

The problem is both kd.h and keyboard.h include types.h so there are re-definitions.  I believe fb.h and kd.h are sufficient for detecting fbcon support.

My system is gentoo linux 2.6.13 amd64, feel free to ask for any additional information. Thanks

I checked out all the various types.h files, and they all have include-once blockers in them. Are you sure this is the actual issue? Can you attach config.log from a configure run that fails the fbcon test so I can verify?

Assuming this was fixed by newer Linux kernel headers, as I couldn't ever reproduce it here.
