After installing php-4.3.10, mod_php-4.3.10 and xdebug-1.3.2, the mod_php doesnt work with xdebug: Starting apache2 while using tail: $ tail -f /var/log/apache2/error_log & $ /etc/init.d/apache2 start * Starting apache2 ... * [ ok ] [Thu Feb 24 11:57:31 2005] [notice] Digest: generating secret for digest authentication ...

Error while starting/stoping apache 2. Information of the xdebug extension arent displayed by phpinfo(). Expected Results: 1. xdebug-1.3.2 should work with mod_php-4.3.10. 2. ebuild should resolve possible dependencies. 1. /usr/lib/extensions/no-debug-non-zts-20020429 I assume that the last numbers in above (..429) determines the php-version against the module was compiled. So further I assume that there must be a dependency to php-version 4.2.9 which is not resolved in the ebuild file. 2. With php-cli on the commandline there seems to be no problem with xdebug. phpinfo() here displays the appropriate pieces of information to the xdebug-extension. 3. some more configuration details: ------------------------------------------------------------------------------------------ Use-Flags for php and mod_php: [ebuild R ] dev-php/php-4.3.10 +X +berkdb +crypt +curl -debug -doc -fdftk -firebird -flash -freetds +gd -gd-external -gdbm -gmp -hardenedphp +imap -informix +ipv6 -java +jpeg -kerberos +ldap -mcal -memlimit -mssql +mysql +ncurses +nls -oci8 +odbc +pam +pdflib +png -postgres +qt +readline -snmp +spell +ssl +tiff +truetype +xml2 -yaz ----------- [ebuild R ] dev-php/mod_php-4.3.10 +X +apache2 +berkdb +crypt +curl -debug -doc -fdftk -firebird -flash -freetds +gd -gd-external -gdbm -gmp -hardenedphp +imap -informix +ipv6 -java +jpeg -kerberos +ldap -mcal -memlimit -mssql +mysql +nls -oci8 +odbc +pam +pdflib +png -postgres +qt -snmp +spell +ssl +tiff +truetype +xml2 -yaz 0 kB Total size of downloads: 0 kB ------------------------------------------------------------------------------------------ net-www/apache-2.0.52-r2 dev-php/php-4.3.10 dev-php/mod_php-4.3.10 dev-php/xdebug-1.3.2 ----------------------------------------------------------------------------------------- PHP Version 4.3.10: ./configure: './configure' '--prefix=/usr' '--host=i686-pc-linux-gnu' '--mandir=/usr/share/man' '--infodir=/usr/share/info' '--datadir=/usr/share' '--sysconfdir=/etc' '--localstatedir=/var/lib' '--libdir=/usr/lib' '--enable-experimental-zts' '--with-apxs2=/usr/sbin/apxs2' '--with-ndbm=/usr' '--with-db4=/usr' '--with-mcrypt=/usr' '--with-mhash=/usr' '--without-interbase' '--without-ming' '--without-swf' '--without-sybase' '--without-gdbm' '--without-fdftk' '--without-java' '--without-mcal' '--with-unixODBC=/usr' '--without-pgsql' '--without-snmp' '--with-xpm-dir=/usr/X11R6' '--without-gmp' '--without-mssql' '--with-pdflib=/usr' '--with-gd' '--enable-gd-native-ttf' '--with-png=/usr' '--with-png-dir=/usr' '--with-jpeg=/usr' '--with-jpeg-dir=/usr' '--enable-exif' '--with-tiff=/usr' '--with-tiff-dir=/usr' '--with-mysql=/usr' '--with-mysql-sock=/var/run/mysqld/mysqld.sock' '--with-freetype-dir=/usr' '--with-ttf=/usr' '--with-t1lib=/usr' '--with-gettext' '--with-qtdom=/usr/qt/3' '--with-pspell=/usr' '--with-openssl=/usr' '--with-imap=/usr' '--with-ldap=/usr' '--with-dom=/usr' '--with-dom-xslt=/usr' '--with-dom-exslt=/usr' '--without-kerberos' '--with-pam' '--disable-memory-limit' '--enable-ipv6' '--without-yaz' '--disable-debug' '--with-curlwrappers' '--with-curl=/usr' '--enable-dbx' '--with-imap-ssl' '--with-zlib=/usr' '--with-zlib-dir=/usr' '--with-sablot=/usr' '--enable-xslt' '--with-xslt-sablot' '--with-xmlrpc' '--enable-wddx' '--with-xml' '--enable-mbstring=all' '--enable-mbregex' '--with-bz2=/usr' '--with-crack=/usr' '--with-cdb' '--enable-pcntl' '--enable-bcmath' '--enable-calendar' '--enable-dbase' '--enable-filepro' '--enable-ftp' '--with-mime-magic=/usr/share/misc/file/magic.mime' '--enable-sockets' '--enable-sysvsem' '--enable-sysvshm' '--enable-sysvmsg' '--with-iconv' '--enable-shmop' '--enable-dio' '--enable-yp' '--without-ncurses' '--without-readline' '--enable-inline-optimization' '--enable-track-vars' '--enable-trans-sid' '--enable-versioning' '--with-config-file-path=/etc/php/apache2-php4' '--without-pear' ------------------------------------------------------------------------------------------ php.ini config: /etc/php/apache2-php4/php.ini or /etc/apache2/conf/php.ini: zend_extension_ts=/usr/lib/extensions/no-debug-non-zts-20020429/xdebug.so -> or with: zend_extension=/usr/lib/extensions/no-debug-non-zts-20020429/xdebug.so ------ /etc/php/cli-php4/php.ini: zend_extension=/usr/lib/extensions/no-debug-non-zts-20020429/xdebug.so ------------------------------------------------------------------------------------------ xdebug.so in filesystem: # ls -al /usr/lib/extensions/no-debug-non-zts-20020429/xdebug.so -rw-r--r-- 1 root root 100128 24.

The xdebug-extension crashes with apache compiled with the USE-flag "threads". When "threads" is on as a global USE-flag apache is compiled with MPM-module worker, if not, its compiled with the MPM-module preforked. The xdebug´s ebuild-file must check whether apache was emerged as mentioned before.
I'm in two minds about whether it's worth adding this test or not. The PHP documentation clearly states that PHP shouldn't be used with threaded Apache2 MPMs. I'll have a think about it.
Hi, This issue is now resolved in the Gentoo PHP Overlay packages. The overlay is available for general use, or you can wait until we add the packages to Portage in the next few weeks. http://svn.gnqs.org/projects/gentoo-php-overlay/ Best regards, Stu
