I try to install Solr PHP extension to my webserver. I already have an XAMPP server and I'm using PECL to install solr
$ cd /opt/lampp/bin
$ sudo ./pecl install solr-1.0.1
But I got the following error:
checking libxml2 install dir... /usr/lib
checking for xml2-config path...
configure: error: xml2-config not found. Please check your libxml2 installation.
ERROR: `/tmp/pear/temp/solr/configure --enable-solr=yes --enable-solr-debug=no --with-curl=
/usr --with-libxml-dir=/usr/lib' failed
During the installation it prompts me to input a path:
libxml2 install prefix [/usr] :
I have tried with enter and the /usr/lib
What shall I input there to not get an error? Or how shall I install to not get an error?
Now I have libxml2 installed through yum install libxml2-devel. But I got some wierd errors now. Here are just a few of them, it ends with:
no such parameter
/tmp/pear/temp/solr/solr_types.h:388: error: declaration for parameter 'client_count' but no such parameter
/tmp/pear/temp/solr/solr_types.h:386: error: declaration for parameter 'document_count' but no such parameter
/tmp/pear/temp/solr/solr_types.h:384: error: declaration for parameter 'request_count' but no such parameter
/tmp/pear/temp/solr/php_solr.c:1185: error: expected '{' at end of input
make: *** [php_solr.lo] Error 1 ERROR: `make' failed
If you're using RHEL/Fedora/CentOS/Scientific linux then you need to install libxml2-devel
yum install libxml2-devel
I could easily install PECL Solr via my systems package manager, probably this works for you as well. I found it very easy so probably worth to share (Fedora 14):
$ sudo yum install php-pecl-solr
A little later I got php-pecl-solr-0.9.11-1.fc14.x86_64 installed, the package's fedora homepage is here.
I could locate the libxml2 version with this command:
$ locate libxml2.so
probably this is helpful as well.
