How can I get cygdrive with msys?

I have projects using cygwin under WinXP. I now must change to msys under Win7-64. The projects access the windows drive letters via cygdrive, e.g. ls /cygdrive/C do get directory listing of C:. Same command with msys ls.exe gives:

/usr/bin/ls: /cygdrive/C: No such file or directory

In msys it works without cygdrive: ls /C

But the projects explicitly need cygdrive. So my question is: Can I get cygdrive back in msys? Or should it be there and someone did something wrong during installation?

Any information is much appreciated, regards

Hans

This is expected; MSYS doesn't need cygwin's cygdrive ugliness.

Again, this is expected; not only does MSYS not need the ugliness of
cygdrive, it explicitly *removes* it.

Okay.

Yes, you can create any mount alias you like:

   $ mkdir /cygdrive
   $ mount c:/ /cygdrive/c
   $ ls /cygdrive/c
   ...shows directory listing...

No. MSYS is behaving as expected.

For archive clarity, it wasn't really removed, the default for the
string changed to "" instead of "cygdrive". Cygwin actually provides
a method to change /cygdrive to anything you want including nothing at
all. Therefore a project depending on /cygdrive hardcoded is broken.

FW: How can I get cygdrive with msys?

In reply to this post by Keith Marshall-3

Hi Keith.

Thanks, that was what I'm looking for (if it works also outside of the
msys-shell simply for all the msys\bin\*.exe, and if it's no problem
that C would be mounted twice then) - unfortunately the mount
does not work :(.

"mount" is a shell script, and it needs other tools which are not
available:

$ mount C:/ /cygdrive/C
/bin/mount: line 189: awk: command not found
/bin/mount: mount point '/cygdrive/C' is already in use

So I need at least awk, but could not find awk in the list of available
tools (only gawk was listed in
"binutils-2.19.51-3-msys-1.0.13.RELEASE_NOTES.txt")

PS.: Sorry for the formatting, I use Outlook 2010 and it allows sending
pure text to some addresses automatically, but other settings are not
good for mailing lists - hope this is a bit better now. But I'm quite
sure
that I may forget to change some setting by hand in the future...

Regards
Hans

Are you suggesting that you use MSYS programs, other than within the
MSYS hosted environment. I know that some users do this, but it is not
a "modus operandum" which we either endorse, or support. If it works
for you, then well and good; if it doesn't, then you are on your own.

WJFFM; (I checked, before I suggested it).

Sure.

Huh?

It *should* be, if you've installed msys-base correctly.

> /bin/mount: mount point '/cygdrive/C' is already in use

Which tells me that you already have a mount assigned to it, in
/etc/fstab; `C:/ /cygdrive/C' perhaps? (This would mean that it's
already mounted, as you want).

In MSYS, gawk and awk are one and the same; *both* names are supported
if you have installed msys-gawk, (which is *required* by msys-base).

Why is this relevant? Why are you even looking at the release notes for
a package which is of use *only* to those developing the MSYS product
itself? I hope you are not trying to use this to support any MinGW (as
opposed to MSYS) compiler. Those release notes are quite explicit in
telling you that this probably is not the binutils that you want; you
need the mingw32-binutils.

You should have the awk command when you installed the base msys
system assuming you installed it with ``mingw-get install msys'' or
``mingw-get install msys-base'' or used the mingw-get-inst installer.

To install
mingw-get install msys-gawk

If it says it is already installed then you need to

mingw-get install --reinstall msys-gawk

Yes, it is better. But you need to read the Etiquette section of
http://mingw.org/lists.shtml.

FW: How can I get cygdrive with msys?

In reply to this post by Keith Marshall-3

I found the awk in the gawk package
(gawk-3.1.7-2-msys-1.0.13-bin.tar.lzma) :).

With that awk the mounting works as expected. I made a script:

#!/bin/sh
#
------------------------------------------------------------------------
----
# mount_cygdrive_C_D.sh: mount C: and D: in /cygdrive
#
# Usage: Open a windows command shell in MSYS root directory, then:
# set PATH=%CD%\bin;%PATH%
# bin\sh.exe mount_cygdrive_C_D.sh
#
# Note: Use for projects which used to use Cygwin and /cygdrive if you
want
# to switch from Cygwin to MSYS
#
# History:
# 2013-07-03 HaSchm
# - Initial revision
#
------------------------------------------------------------------------
----

# check that awk exists
if [ ! -e "/bin/awk.exe" ]
then
echo Error: "/bin/awk.exe does not exist (needed in mount script)."
exit 1 #exit shell script
fi

# make dir /cygdrive if needed
if [ -d "/cygdrive" ]
then
echo "Directory /cygdrive already exists."
else
mkdir /cygdrive
fi

# mount C: if needed
if [ -d "/cygdrive/C" ]
then
echo "Directory /cygdrive/C already exists."
else
mount C:/ /cygdrive/C
fi

# mount D: if needed
if [ ! -d "D:/" ]
then
echo "Directory D:/ does not exist (can not be mounted)."
else
#echo "Directory D:/ exists."
if [ -d "/cygdrive/D" ]
then
echo "Directory /cygdrive/D already exists."
else
mount D:/ /cygdrive/D
fi
fi

# eof
