It is Windows and MSYS just pretends to be POSIX.  Anything windows
though will be slower than Linux, it is just fact.

That is correct, because native programs such as MinGW's gcc doesn't
understand a symbolic link as Cygwin had architected it we changed it
to do a copy.  I use sysinternals' junction.exe to create a junction
point instead.  Maybe one day will do the same in MSYS for symbolic
links of directories but that will be a long while.

Glad i could help :) i use junction myself because i dont want two
copies of mingws runtime libraries when using sysroots (saves some
space) also pretty usefull for other stuff.

HI all,
I'm trying to run this command: find -iname '*.[ch]' -o -iname
'*.[ch]pp' > cscope.files . With same folder, I found the speed is far
lower than in real Linux. Do you have similar experiments?
Thanks.
Marvin

Hi Ralph,
Thanks for your help! junction.exe is just what I want.

Msys does not support symlinks unfortunatly.
The code for that was removed because mingw does not understand cygwin
symlinks. There is one workaround though, google junction.exe from
sysinternals and put it somewhere in your PATH (the msys bin folder is
ok) now to make a link to say a folder do this from the msys shell
junction <path to put the link to your folder> <path to your folder>
(you can use /mingw/something if in msys) else you need the full
windows path like C:\mingw\something.

so why does this work when cygwin symlinks dont ? mingw is a windows
compiler and understands NT junctions (existed since win2k if i
remember correctly) but not cygwin symlinks (which emulates linux
symlinks).

Hope this helps

HI all,
I'm trying to use ln command in msys, such as 'ln -s A B'. A is a
folder, I just want to create B as for A's symbolic. However, I find
it didn't  create a symbolic name at all, it just execute copy
command. Could you tell me how to create a symbolic name in msys.
Thanks.
Marvin
