Hello

I'm trying to compile phpredis (get latest from github) as an extension of php 5.2.10 . When i ran the make command, this error show up :

/bin/sh /src/nicolasff-phpredis-38e2cca/libtool --mode=compile cc -I. -I/src/nicolasff-phpredis-38e2cca -DPHP_ATOM_INC -I/src/nicolasff-phpredis-38e2cca/include -I/src/nicolasff-phpredis-38e2cca/main -I/src/nicolasff-phpredis-38e2cca -I/zserver/php/include/php -I/zserver/php/include/php/main -I/zserver/php/include/php/TSRM -I/zserver/php/include/php/Zend -I/zserver/php/include/php/ext -I/zserver/php/include/php/ext/date/lib -DHAVE_CONFIG_H -g -O2 -c /src/nicolasff-phpredis-38e2cca/redis.c -o redis.lo
