[FFmpeg-devel] Build Errors

My bad, I actually put a log in the below statements, to figure out where it stuck, but find that it works fine.

However the configure time seems to have increased multiple times, and it spends a lot of time inside the loop below, not sure if any changes have been made.

The normal configure time is close to 1 min for all the other stuff, but the below loop is taking close to 10 min ?

With no updates in config log during this time, and no on screen, user can easily confuse if the configure is happening correctly.

Would be good to have either some update on the screen or in the log file, if we still need to keep the changes that increased this to 10 min. Ideally remove the changes and switch to the older ones, where this loop was just a second or two.
 
Thanks,
Yogender

You get the second error because you disabled the code to cleanup the library list, which makes it far far far longer.
I build on windows regularly and I have not noticed any problems with configure getting stuck, though.
