Gurus,

When I compile an executable using perlapp (Version 6.0.0, build 117102),
it seems to have a problem running on an XP machine that a. doesn't have
Perl installed on it, and b. doesn't have the directory C:\Temp. Here's
the error message:

mkdir <"C:\Temp\pdk-Secuser\"> failed, errno=2
Panic: Can't find temp dir for perlapp

where "Secuser" is the logged in user (i.e.: the directory it's trying to
create is C:\Temp\pdk-). Is this a problem with executables
compiled to be freestanding (i.e.: to run on PCs that don't have Perl
installed)?

We're doing more digging here, but maybe someone knows what's going on and
can save us looking for the elephant in the hamster cage...

Many thanks!

Gurus,



When I compile an executable using perlapp (Version 6.0.0, build 117102), it seems to have a problem running on an XP machine that a. doesn't have Perl installed on it, and b. doesn't have the directory C:\Temp.  Here's the error message:



mkdir <"C:\Temp\pdk-Secuser\"> failed, errno=2

Panic:  Can't find temp dir for perlapp



where "Secuser" is the logged in user (i.e.: the directory it's trying to create is C:\Temp\pdk-<username>). Is this a problem with executables compiled to be freestanding (i.e.: to run on PCs that don't have Perl installed)?

Executables generated by PerlApp use the Windows GetTempPath() API to
determine the location of the TEMP directory:

http://msdn2.microsoft.com/en-us/library/aa364992.aspx

| Remarks
|
| The GetTempPath function checks for the existence of environment variables
| in the following order and uses the first path found:
|
| 1. The path specified by the TMP environment variable.
| 2. The path specified by the TEMP environment variable.
| 3. The path specified by the USERPROFILE environment variable.
| 4. The Windows directory.

This means if you have TMP set to point to C:\Temp, but don't actually
have that directory, then the application will show the error you see
above.

In some way I would claim that you have a misconfigured Windows system,
but I guess PerlApp should also try harder, and just create "C:\Temp" if
it doesn't exist. But that could still fail if you set TMP to "X:\Temp"
and you don't have an X: drive.

Maybe the best strategy is to check the 4 locations GetTempPath() would
try ourselves, and use the first one that already exists.

This could still fail if the user unsets USERPROFILE and doesn't have
write access to the Windows directory, but I think it is valid to abort
in that situation.

Cheers,
-Jan

From the PerlApp help file: (Ver 5.2)
File Extraction
When the executable built with PerlApp runs, it will extract its dynamic
object files in the /tmp/pdk directory. If the application was built
using the --clean option, PerlApp will also append the process id to
this directory name to avoid race conditions during cleanup. The
directory location can be set using the TMPDIR environment variable. On
Windows the TEMP environment variable can be used to override the
location. You may also hardcode the location using the the --tmpdir
commandline option.

Check to see if user "Secuser" has the environmental variable "TEMP" set
to "C:\TEMP" and either change it to the proper temporary directory
location or use the --tmpdir to force perlapp to unpack elsewhere.

I have never used it (I'm a cheapskate) but it would seem that the clue
is in the documentation
(http://aspn.activestate.com/ASPN/docs/PDK/6.0/PerlApp.html# perlapp_file
s). So that would appear to mean that either your build or the
environment(s) that you run the app in need to be fixed to point to a
temporary directory that actually exists.
