[Ffmpeg-devel] Bizarre build problem of the day (original) (raw)

First, the background. System: Windows XP SP2, running MinGW and MSys. ffmpeg from cvs, checked out Wednesday, 2/22/2006.

Symptom: Changing directory to ffmpeg and running configure under MSys caused the system to totally lock up, requiring a hard shutdown (hold the power button down for 5 seconds on the notebook).

Solution: For whatever reason, a process named LVPrcSrv took over 99% of the processor after "Creating config.mak and config.h..." was displayed during the run of configure. This was discovered from watching Windows Task Manager during a run. LVPrcSrv is a Logitech QuickCam process that is automatically started during system startup and is supposed to run in the background. I was able to completely run configure if I killed LVPrcSrv before starting configure. This is the first time this has occurred, and the problem only occurs with this combination of ffmpeg, MinGW/MSys, and configure. I successfully build under MinGW/MSys without problems with other software projects with this same combination.

I'm not pointing any fingers at anybody, unless you want to point at Windows on general principal. I just find this whole thing weird.
