for a while after 1.0, in CVS, there was code to check for OS support for SSE instructions. since that required a fork() inside the library I have decided to remove it. so now to get SSE support you have to configure with --sse-os. if I think of a clean way to implement this I'll put it back in. also, there's been some suspicion that the 3dnow! stuff is causing crashes, so I disabled

Can't you write a script for ./configure that checks for this, rather than having the library do the check each time it's used? If not, perhaps check /proc/cpuinfo or something. The DoIHaveSSE and DoIHave3DNow checks could fork() if the system provides fork(); if not, the checks would return false. Couldn't you also just check for fork() in the configure script? Matt, will the debian packages have 3DNow support and SSE support? -- Asheesh. On Tue, 13 Nov 2001, Josh Coalson wrote...

I turned off 3dnow by default...
