#42106 [NEW]: Build fails due to duplicate symbols (missing externs)
From: chris at improbable dot org
Operating system: Mac OS X
PHP version: 5.2.3
PHP Bug Type: Compile Failure
Bug description: Build fails due to duplicate symbols (missing externs)
Description:
------------
The build failed with a duplicate symbol error:
ld64-74.4 failed: duplicate symbol _php_bz2_filter_factory in
ext/bz2/bz2_filter.o and ext/bz2/bz2.o
This was solved by adding extern to the php_bz2_filter_factory
declaration in ext/bz2/php_bz2.h
An identical problem happened with Zend/zend_ini_scanner.c with the
yytext declaration on line 478 (there is an earlier declaration in the
same file which is already declared extern).
Reproduce code:
---------------
CFLAGS=-fast ./configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --disable-dependency-tracking
--with-apxs2=/usr/sbin/apxs --with-ldap=/usr --enable-cli
--with-zlib-dir=/usr --with-xml --enable-exif --enable-mbstring
--enable-mbregex --enable-sockets --with-curl=/usr
--with-config-file-path=/etc --sysconfdir=/private/etc
--with-mysql-sock=/tmp/mysql --with-mysql=shared,/usr/local/mysql
--with-mysqli=shared,which mysql_config --with-pdo-mysql=shared,`which
mysql_config` --with-openssl --with-xmlrpc --with-xsl=/usr
--with-pear=/Library/PHP --with-bz2 --enable-bcmath --disable-cgi
--enable-zip --enable-memory-limit --enable-pcntl --with-zlib=/usr
--with-zlib-dir=/usr --with-ldap --enable-memcache
