>Try dir /a - perhaps the attributes on the .lnk file are weird...

With the command "cmd /c dir /a", I get 3 more files, including libblas.a
and liblapack.a. (The third one is libg.a.) I saw, with Windows file
browser, that for these three files:
-the mark "Fichier caché" (hidden file) is blocked on 'off';
-the mark "Archive" is set to 'off', too.

I tried to set this last mark to 'on' (because the other .a files in this
directory have this mark 'on'), but 'dir' still does not recognize these
lib*.a files.

Do you think I have to do the same trick?

Thanks for the help,

Excellent - good to know that the trick is consistent for other libraries
too!

I don't think it is - I think it's to do with abstractions in libtool. Try
resetting the permissions on the files in C:\cygwin\lib using Windows
Explorer (though note that may upset Cygwin!!!).

I expect that problem with your .a files is Cygwin's interaction with NTFS
permissions - if you only use Cygwin to build OCaml and related things then
I'd suggest having the environment variable CYGWIN=nontsec set (which,
counter-intuitively, means "use NT native file permissions instead of
POSIX-over-NTFS"). I expect that your installation of the libraries
inherited weird permissions when you installed them because Cygwin by
default emulates Unix's user-group-other permissions rather than NT's
inherited ACLs which is fine if you spend your entire life in Cygwin's bash
but is a pain if you use Windows on the same files as well (it's OK under XP
but under Vista manipulation of any files touched by Cygwin becomes
virtually impossible owing, admittedly, to clear bugs in Vista's crappy
explorer making any operations hideously slow...)

I followed your trick and now compilation is OK.

Just a remark however (maybe it's the key for the porblem): when renaming
the old 'liblapack.a', Windows asked me a confirmation, arguing that the
file is a system file.

Thank you for the help,

"ls -l"?

or

"cmd /c dir"


With "cmd /c dir", you should see a file "liblapack.a.lnk" (in /lib). 
Can you see it?  Is there a file "liblapack.a" as well?
