You need to provide more information. What *exact* configure command are you using, specifically what are you providing for --host, --build, --target, and --prefix? What is the build host, MSYS or Cygwin? Are you providing a relative path to the location of configure or an absolute path? > build/gengtype.exe > /home/seb/combined/gcc/input.h: No such file or directory Here it looks like you have a mingw program trying to access posix paths. That won't work, mingw programs need to use win32 paths. > The output from "ls -l /home/seb/combined/gcc/input.h" > -rw-r--r-- 2 seb Administ 2896 Jun 25 2005 > /home/seb/combined/gcc/input.h This works because ls is a MSYS or Cygwin app, not a native app, so it understands posix paths and knows how to map /home/seb to a Windows path. Or at least that's my guess, because you didn't give enough information to know for sure. Brian
