Re: [Help-smalltalk] Error while opening URL via FileStream

[Stefan Krecher]

without strace i get the following exception. I suspect that  the
Exception occurs while trying to write a temporary file.
Looking into URIResolver.st it seems that it tries to write to
UserProfileSettings default settingAt: 'tmpDir' - which is initialized
with the environment variable TEMP (and defaults to /tmp/ which is
nonexistent on Android).
But  exporting TEMP='./' does not seem to have an effect. Smalltalk
getenv: 'TEMP' returns the correct result but UserProfileSettings
default settingAt: 'tmpDir' returns an empty string ....
