1. Sorry, not at least in version n1.2. Here is "configure --help" output for ffmpeg version n1.2: http://pastebin.com/vKHiZvv5. I've also checked the configure code. > > (pls note that this does not work: > > "--as=/absolute/path/to/gas-preprocessor.pl /path/to/as..." ). > > Please test "/path/to/gcc" > > 2. I'm afraid it doesn't matter if you are using gcc, as or "whatever compiler", the problem lies in the ffmpeg configure program *which always defaults to the gas-preproc in the search path* because of the root cause described at point 2.2 below. 2.1. For example, If you configure ffmpeg with: --as='/Users/Shared/xbmc-depends/buildtools-native/bin/gas-preprocessor.pl/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' 2.2. The basic problem lies in configure, line 3247 which is the line that is commented out by the xbmc patch: 3246: darwin) 3247: gas="gas-preprocessor.pl $cc" | | +---- Wrong path!! 2,2. Configure will produce the following config.mak ( http://pastebin.com/xB0GCEJd) # config.mak - Automatically generated by configure - do not modify! AS=gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/ iPhoneOS.platform/Developer/usr/bin/gcc | | +---- Wrong path!! 2.4. Thus, the end result when running make will still always be: gas-preprocessor.pl/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -I. -I./ [....] "Unable to identify target architecture at */usr/local/bin/ gas-preprocessor.pl* line 82." (forced error) | | +---- Wrong path!! Patch (extremely) welcome! > (My idea is to grep for the right syntax in configure, > contrary to you I cannot test.) > > 3. Ok, I'll check with Mans Rullgard to see what can be done about it...
