On brandnew SVN download, after setting the correct directory paths, configure aborts with

after the Plugins section is displayed. Do not get to the "next" button. This happens after the first time you change settings.

I got the same error, but only after having changed some settings.

Problem disappeard in rev 11778 -- TW

Nope. Problem still exists.

Test case: Update a fresh twiki from SVN. Run configure. Fix the path settings. Save. Go back to configure. -- TW

---

This probably happens if you have no errors or warnings. Since I have both, I can't check. I have forced initialisation of the requisite variables, please close this if it now works. Thanks.

There were warnings present when this occurred.

But problem is gone now... -- TW

Just re-committing to fix line ends. This isn't just nitpicking, it won't run on linux because the DOSish <CR> is added to the shebang /usr/bin/perl, and there isn't such a file like /usr/bin/perl<CR> -- haj

Broken again. On my installation there is an error message right after the 2 read-only sections:

Use of uninitialized value in concatenation (.) or string at /e/www/twiki-latest/twiki/lib/TWiki/Configure/UIs/Value.pm line 43.

after the first section. On bug base I do not get this error message. -- TW

Sorry - I am to blame. I added the -w switch to configure prematurely in Item3044, and configure intentionally dies on any warning. I'll remove the -w from SVN and keep it in my local test scenario only. The reason that you sometimes do get the error and sometimes don't is that configure discovers many variables depending on your environment, and all environments are different.

Verified that it is working again -- TW

Broken again at 11916.

This time Crawford added the -w switch...

Unfortunately the error message doesn't give (it can't) any hint which variable might be uninitialized. If check routines are allowed to return undef, then the concatenation has to take care for that, and that's what I changed for now. There are too many of them....

Please re-open if the problem still persists (I'm sure you will )
