Hi,

I'm trying to get Mnesia going under Windows.
>From a cygwin rxvt/tcsh I get the following:
-------------
> erl -mnesia dir d:/cygwin/home/tobbe/tmp
Eshell V5.0.2 (abort with ^G)
1> init:get_arguments().
[{root,["D:\ERL50~1.2"]},
{progname,["erl"]},
{mnesia,["dir","d:/cygwin/home/tobbe/tmp"]},
{home,["C:\WINDOWS"]}]
2> application:start(mnesia).

=ERROR REPORT==== 24-Aug-2001::11:25:02 ===
application_controller: syntax error before: '/': d:/cygwin/home/tobbe/tmp
{error,{bad_environment_value,"d:/cygwin/home/tobbe/tmp"}}
---------------

But ls/0 works fine (tmp is empty):
---------------
3> ls("d:/cygwin/home/tobbe/tmp").
ok
---------------

And here is another example:
------------------
4> file:open("/cygwin/home/tobbe/tmp/heja",[write]).
{ok,<0.47.0>}
5>
<Ctrl-c>
> ls tmp
heja
> erl -mnesia dir /cygwin/home/tobbe/tmp
Eshell V5.0.2 (abort with ^G)
1> application:start(mnesia).
{error,{bad_environment_value,"/cygwin/home/tobbe/tmp"}}

=ERROR REPORT==== 24-Aug-2001::11:58:53 ===
application_controller: syntax error before: '/': /cygwin/home/tobbe/tmp
--------------------

Ideas anyone ?

Cheers /Tobbe

Hi.

Could it be that you should use (backslash) instead of / (slash)
as directory delimiter?

I ran into a similar problem today in my .bat script to run erlang on Win XP. I tried various combinations of quoted and non-quoted paths before eventually finding an example that uses both single and double quotes. That's the one that works:

Code:
"C:\Program Files\erl5.6.1\bin\werl.exe"  -mnesia dir '"C:/Documents and Settings/Joe User/My Documents/mnesia"'

Code:
 erl -mnesia dir "'/Temp/funk'"

double quote followed by single quote works in cygwin with bash.
