I have perl 5.10.0. Ikiwiki 2.44 compiles fine. Compiling 2.45 fails after 'make':
|
|
|
|
perl -Iblib/lib ikiwiki.out -libdir . -setup docwiki.setup -refresh
|
|
refreshing wiki..
|

OK, this is what I'm getting:
|
|
|
|
$ perl -Iblib/lib -V
|
|
@INC:
|
|
blib/lib
|
|

I ran the following in my current 2.45 source dir, where the `make` already succeded. If you need it, I can post the output
|
|
in the case where `make` fails.
|
|
|
|
$ strace perl -Iblib/lib -e 'use IkiWiki' 2>&1 |grep IkiWiki.pm

I finally had some time to look into this again.
|
|
|
|
I wiped ikiwiki off my system, and then installed version 2.41. I tried installing
|
|
2.46 and get the same error as above, so I'll be using 2.46 below. (BTW, the debian
|
|
page still lists 2.45 as current; I had to fiddle with the download link to get 2.46).
|
|
|
|
After running `./Makefile.PL` I get:
|
|
|
|
$ perl -Iblib/lib -V
|
|
[bunch of lines snipped]
|
|
@INC:
|
|
blib/lib
|
|
[bunch of paths snipped]
|
|
|
|
Running the strace:
|
|
|
|
$ strace perl -Iblib/lib -e 'use IkiWiki' 2>&1 |grep IkiWiki.pm
|
|
|
|
I get a bunch of ENOENTs and then at the end:
|
|
|
|
stat64("./IkiWiki.pmc", 0xbfa2fe5c) = -1 ENOENT (No such file or directory)
|
|
stat64("./IkiWiki.pm", {st_mode=S_IFREG|0644, st_size=31987, ...}) = 0
|
|
open("./IkiWiki.pm", O_RDONLY|O_LARGEFILE) = 3
|
|
|
|
After running `make` (and having it fail as described above):
|
|
|
|
$ strace perl -Iblib/lib -e 'use IkiWiki' 2>&1 |grep IkiWiki.pm
|
|
stat64("blib/lib/IkiWiki.pmc", 0xbfd7999c) = -1 ENOENT (No such file or directory)
|
|
stat64("blib/lib/IkiWiki.pm", {st_mode=S_IFREG|0444, st_size=31901, ...}) = 0
|
|
open("blib/lib/IkiWiki.pm", O_RDONLY|O_LARGEFILE) = 3
|
|
|
|
I don't know what is going on, but I'll run any more tests you need me to.
|
|
|
|

I have 2.46 installed and I can reproduce the bug reported against 2.49. The command that fails is:
|
|
|
|
$ /usr/bin/perl -Iblib/lib ikiwiki.out -libdir . -setup docwiki.setup -refresh
|
|
docwiki.setup: Failed to load plugin IkiWiki::Plugin::inline: Too many arguments for IkiWiki::htmlize at IkiWiki/Plugin/inline.pm line 359, near "))"
|
|
Compilation failed in require at (eval 14) line 2.
|
|
BEGIN failed--compilation aborted at (eval 14) line 2.
|
|
BEGIN failed--compilation aborted at (eval 10) line 21.
|
|
|
|
strace -f produces a 112K file. I don't know enough to be comfortable analyzing it.
|
|
However, lines like:
|
|
|
|
stat64("/usr/local/share/perl5/site_perl/5.10.0/IkiWiki.pm", {st_mode=S_IFREG|0444, st_size=31982, ...}) = 0
|
|
|
|
make me think the make process is not completely independent of a previous
|
|
installation. Joey, should I email you the strace log file?

Joey, thanks for your time and effort looking into this.
|
|
|
|
I checked with `which`: `perl` is indeed `/usr/bin/perl`. The commands fail similarly when
|
|
calling `perl` and `/usr/bin/perl`.
|
|
|
|
However, you might be into something with your `libdir` idea. If I remove it from the
|
|
command line, the command succeeds. In other words, if I run
|
|
|
|
perl -Iblib/lib ikiwiki.out -setup docwiki.setup -refresh
|
|
|
|
then it works perfectly.
|
|
|
|
> Well, that's just weird, because `libdir` is handled by code in IkiWiki.pm.
|
|
> So I don't see how setting it could affect its searching for IkiWiki.pm at all,
|
|
> actually. It could only affect its searching for files loaded later. Anyway,
|
|

|

|

By the way, I'm running Arch linux. The perl build script is a bit long, but I
|
|
see they install a patch to modify @INC: <http://repos.archlinux.org/viewvc.cgi/perl/repos/core-i686/perl-5.10.0-archlinux-inc-order.patch?revision=1&view=markup>
|
|
|
|
Would you suggest I try rebuilding perl without this patch? Debian has a huge perl patch (102K!);
|
|
it's not straightforward for me to see if they do something similar to Arch.
|
|
