1You may run these scripts to build a Tiano Cross compiler. They have been\r

18CYGWIN Notes\r
19\r
20You should setup cygwin to use binmode on all mounts. When you initially\r
21install cygwin it gives you the choice of Unix file mode (recommended) or DOS\r
22file mode. Unix mode will cause all the cygwin directories to be mounted in\r
23binmode, while DOS will mount the dirs in textmode. Here is an example of a\r
24cygwin install where the dirs are (properly) mounted in binmode.\r
25\r
26C:\cygwin\bin on /usr/bin type user (binmode)\r
27C:\cygwin\lib on /usr/lib type user (binmode)\r
28c:\workspace on /workspace type system (binmode)\r
29C:\cygwin on / type user (binmode)\r
30\r
31If you use textmode, it is likely that the build will fail in a way that is\r
32hard to debug.\r
33\r
34Cygwin is pretty slow, so it is not recommended for large builds.\r
