When emerging app-text/xpdf-3.02-r2 on amd64 (with the "nodrm" USE flag set), it successfully emerges but at the next "emerge -avuDN world" it will be recompiled again, incorrectly assuming the "nodrm" USE flag had changed. Reproducible: Always Steps to Reproduce: 1.emerge the package 2.emerge with -uN again in order to check for necessary updating Actual Results: Package will update again although nothing has changed Expected Results: The package should realize it is already up-to-date While the emerge operation itself successfully completes, a warning !!! WARNING: Expected SLOT='0', got '' is issues which might be connected to the cause of the actual problem. I also noticed that indeed no file /var/db/pkg/app-text/xpdf-3.02-r2/SLOT has been created by the emerge operation, although such a file is usually present for other sucessfully installed ebuilds. (On the other hand, the xpdf ebuild uses EAPI==2 and might therefore be installed somehow differently.)

Please attach your /etc/portage/env/app-text/xpdf to this bug report. It will very likely provide the solution to this problem.
Created attachment 188969 [details] My portage override for the package Actually, this "file" is only a symlink to the actual file /etc/portage/env/heavily-optimized which is used by dozens if not hundreds of my ebuilds as /etc/portage/env overrides. It has always worked so far - this issue would the first case where it failed (if it really should turn out to be the overrides's fault). To explain in more detail: My standard CFLAGS only include -O2 with no special further optimizations. This is OK for all packages where execution speed is not a concern, and it usually created somewhat smaller executables as such created with -O3 (due to loop unrolling and inlining, for instance). Packages where speed is a concern, however, I use the env override script attached to this posting in order to modify CFLAGS, FEATURES etc. for heavyweight -O3 optimization.
(In reply to comment #6) > Please attach your /etc/portage/env/app-text/xpdf to this bug report. It will > very likely provide the solution to this problem. Here it is - see the previous posting. I have carefully written the script in order to minimize the possibility for name clashes, but it might turn out I made some mistake of course.
Explaining what my script does (or *should* do): Firstly, if the USE flag for a package include "debug", it does not do anything by itself but sources another override script /etc/portage/env/debugging instead. This way I do not need to change the symlinks if I set the "debug" USE flag temporarily. However, this does not apply to this bug report, as I am not using the "debug" USE flag with this ebuild. Secondly, all locally used variables should have been declared "local". For global names, all identifiers include a 128 bit UUID (encoded as base 35 ASCII strings) in order to minimize any chance for name clashes. Thirdly, running the snippet should not leave any traces after it is done except for modifying $USE, $FEATURES etc. to the desired extent. This means any globally defined functions should have been removed when the script finishes. For the operation of the script itself, it basically consists of 2 nested loops. The outer loop is governed by local variable $S1 and represents the basic action to be processed yet. The inner loop governed by local $S2 controls to which actual environment variable ($USE, $FEATURES etc) the action described by $S1 will actually apply. The actions of $S1 breaks the modification down to phases like reading the variable, process it token by token, and writing it back at the end.
By carefully proofreading my script I actually *did* find a problem: It uselessly sets a variable $S3 to a value, although that variable is never be used again. Although this has no effect on what the script does otherwise, it does "pollute" the global namespace with that variable. I fixed that now - but no change. I still get the following message during the install phase: >>> Installing app-text/xpdf-3.02-r2 !!! WARNING: Expected SLOT='0', got ''
It finally occurred to me that it might be a good idea to try re-emerging the package without any portage override at all! And ... shame on me ... it *worked* this time! Which means, there must be *some* interaction going on between by override script and the ebuild - although I still have not the slightest idea *how*. Or the ebuild does not like some of my optimization settings per se. Anyway, I will examine that and will close the bug if it turns out that my override script is actually to take the blame. Ashes on my head, then! On the other hand, the ebuild might still have some issues. For instance, I noticed a vast difference in running time between my -O2 default flags and when using the -O3 override: Without the override, the ebuild ran through quite swiftly. With the override, however, there is a remarkable delay just after applying the patch, and this takes a minute or where no visible output is generated. It seems the ebuild is doing something lengthly in the configure phase, but I can't see a reason for the big timely difference in comparison to the override-less version. Anyway, I'll investigate and post any findings here. Perhaps this turns out to be some hidden Portage bug and is not directly related to kpdf at all. EAPI=2 seems not yet to be widely used anyway!
I have found the cause of the problem! It is a quoting issue in my override script: This seems to be the first ebuild which puts a quoted string into $CFLAGS, which contains escaped quotes itself. This made the shells substitutions go crazy in some way I still have to figure out; but it's clearly my fault. I therefore fullheartedly want to apologize to all for bugging them with this phantom bug report - I'm really SORRY for wasting everyone's time. On the plus side, I will make the fixed script available to the community in case someone else might want to use it. That way your effort may not not a complete waste! Sorry again, and closing the bug as INVALID.
