I am getting this error “configure: WARNING: You will need re2c 0.9.11 or later if you want to regenerate PHP parsers.” while i tried to install json support with PHP 5.1.6
What is re2c?
re2c is a tool for writing very fast and very flexible scanners. Unlike any other such tool, re2c focuses on generating high efficient code for regular expression matching. As a result this allows a much broader range of use than any traditional lexer offers. And Last but not least re2c generates warning free code that is equal to hand-written code in terms of size, speed and quality.
I download the wget ftp://188.8.131.52/linux/dag/redhat/el4/en/x86_64/dag/RPMS/re2c-0.12.3-1.el4.rf.x86_64.rpm and installed on the server
#rpm -ivh re2c-0.12.3-1.el4.rf.x86_64.rpm
./configure –with-php-config=/home/user/dev/php/bin/php-config> –with-json
make && make install
cp modules/json.so /home/user/dev/php/lib/php/extensions/
vim /home/user/dev/php/lib/php.ini and add extention extension=json.so
