Bug 141476 – media-video/spca5xx-20060501: compilation fail with kernel 2.6.18-rc2

• Status: RESOLVED FIXED
• Product: Gentoo Linux

Hi everyone !!
There is a bug with spca5xx last version ( 20060501 ) when you compile it with the last kernel installed ( vanilla-sources-2.6.18-rc2 ). Indeed, the interface for v4l has changed in this new version, and so included files aren't correctly included..
