Bug 171610 – www-apps/dokuwiki-20061106 needs php w/ USE="expat/xml"

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Philippe Chaintreuil 2007-03-20 20:36:42 UTC]

When searching with 20061106, I get one result, followed by the error:

Fatal error: Call to undefined function: utf8_decode() in /var/www/localhost/htdocs/dokuwiki/inc/utf8.php on line 123

DokuWiki's bug tracker has an old, closed bug that refers to something similar to this indicating that it's due to an incomplete/limited build:

http://bugs.splitbrain.org/?do=details&id=342

Since this appears to be a required function, DokuWiki should require this function to exist in PHP.

I don't know which of the billions of use flags for PHP this function depends on.

Here are my use flags for PHP:

dev-lang/php-4.4.6  USE="apache2 berkdb bzip2 cgi cli crypt gd gdbm iconv mysql ncurses pcre readline session snmp ssl truetype unicode xml zlib -adabas -apache -bcmath -birdstep -calendar -cdb -cjk -concurrentmodphp -ctype -curl -db2 -dbase -dbmaker -dbx -debug -discard-path -doc -empress -empress-bcs -esoob -exif -expat -fastbuild -fdftk -filepro -firebird -flatfile -force-cgi-redirect -frontbase -ftp -gd-external -gmp -hyperwave-api -imap -informix -inifile -interbase -iodbc -ipv6 -java-external -java-internal -kerberos -ldap -libedit -mcal -mcve -memlimit -mhash -ming -mnogosearch -msql -mssql -nls -oci8 -oci8-instant-client -odbc -oracle7 -overload -pcntl -pfpro -pic -posix -postgres -recode -sapdb -sharedext -sharedmem -sockets -solid -spell -sqlite -suhosin -sybase -sybase-ct -sysvipc -threads -tokenizer -wddx -xmlrpc -xpm -xsl -yaz -zip"

Also note that this error does not happen when the search returns no results.

Reproducible: Always

Steps to Reproduce:
1. Search for "dokuwiki" in dokuwiki

Recompile your PHP w/ USE=expat if you are really using php-4; for any other version you need USE=xml

[Comment 3 Philippe Chaintreuil 2007-03-21 12:43:57 UTC]

Roger that.

A rebuild of php4 with USE="expat" fixes the search error.

The ebuild probably needs something to warn you or detect that you don't have the proper PHP use flags.

[Comment 4 Andrej Kacian (RETIRED) 2007-03-23 20:45:13 UTC]

Ok, 20061106 now checks for the USE flag. The check is both PHP4 and PHP5 aware.

Thanks for your report!

Thanks Andrej!
