I have tried to update avidemux to the latest version, but the first compilation failed. I took a look and seems like avidemux can't build if -fforce-addr flag is set in CFLAGS (just like xine-lib). The attached ebuild is fixed with the filter-flag for -fforce-addr.
Created attachment 38164 [details] avidemux-2.0.28.ebuild
Looks like bug 61612 is a duplicate of this one.
Yes the error is the same one I had with -fforce-addr enabled. I'm sorry I hadn't found it when searching for a previous report.
In cvs. Thanks for the bg report!
