Hi Keith Thanks for your reply. In a msydvlpr shell I get --------------------------------------------------- GNUCash@ELSHADAI ~ $ uname -orv uname: invalid option -- o Try `uname --help' for more information. GNUCash@ELSHADAI ~ $ sh --version GNU bash, version 2.04.0(1)-release (i686-pc-msys) Copyright 1999 Free Software Foundation, Inc. GNUCash@ELSHADAI ~ $ -------------------------------------------------------------- Obviously I need to update. This is the enviroment I get when compiling GNUCash from their packaging svn. I know that it creates other bin subdir when installing the compiler tools. I will need to work out how to add these bin subdir to .bashrc so I can test why gnucash compiles very unreliably on this machine. It has been suggested to me that I could have a race condition in rm Is there a whereis command under msys/mingw?
