--- Comment #3 from Rainer Emrich <rai...@emrich-ebersheim.de> --- (In reply to Jeffrey A. Law from comment #2) > When using a sysroot STARTFILE_PREFIX is supposed to be relative to the > sysroot variable -- meaning the mingw port is no longer going to be looking > in /mingw/lib by default. Instead it should be looking in > $sysroot/mingw/lib. I don't see why this request is invalid. I have the libraries and start files at /x86_64-w64-trunk/mingw/lib and configured gcc including "--with-sysroot=/x86_64-w64-trunk". That's exactly what you describe. This already worked for years until your change and it's broken now! Cheers Rainer
