Forum OpenACS Development: Re: Win32-OpenACS Version 1.8

This could work for you as a workaround. We've fixed that overloading that function adding this code to one of our *-init.tcl procs:

if { [ns_info platform] == "win32"} {
rename ns_tmpnam aol_tmpnam
proc ns_tmpnam {} {
set tmp [aol_tmpnam]
set dir [parameter::get_from_package_key -package_key acs-subsite -parameter TmpDir]
return "${dir}${tmp}"
}
}

You just need to make sure that the MainSite parameter TmpDir in the site-map has the right path (i.e. C:\temp ).

In Windows, according to their documentation, the C function tmpnam() is deprecated and is not safe. They recommend to use tempnam(dir,filename) instead where you can specify the path and the filename.

Hope that helps!

The changes you proposed in your last post are allmost perfect. I had to change them as follows:

int i;
char *buf = _tempnam("/tmp", "nsd");

if (buf == NULL) {
Tcl_SetResult(interp, "could not generate temporary filename.", TCL_STATIC);
return TCL_ERROR;
}
/*
Change back slash characters into slash characters
*/
for (i = 0; i < strlen(buf); i++) {
if (buf[i] == '\\') buf[i] = '/';
}
/*
The documentation says that _tempnam() allocates memory via
malloc(); to be sure, that the "right" free() is used, we do
not use TCL_DYNAMIC but the TCL_VOLATILE followed by the manual
free().
*/
Tcl_SetResult(interp, buf, TCL_VOLATILE);
free(buf);

The problem is that _tempname generates file names in the Windows style (i.e. with back slash characters) and SqlLdr doesn't like that style for the "control" parameter (it requires normal slash characters).

Once again many thanks,
