Hi all, I am trying to build ESL library for PHP but received the error below. I checked all pre-requisite libraries according to ESL wiki page and seem to have them all. libxml2-dev libpcre3-dev libcurl4-openssl-dev libgmp3-dev libaspell-dev python-dev php5-dev libonig-dev libqdbm-dev libedit-dev libdb-dev. It's throwing an error for an invalid conversion from const char to char in esl_wrapp.cpp. I am running FreeSWITCH Version 1.2.12+git~20130816T225403Z~8566ffa82a on Linux Mint 14. Any idea on how to fix this error?
