Under Linux, errors are reported when compiling and installing PHP:
libxml2 configure: error: xml2-config not found. Please check your libxml2 installation.
However, libxml2 has been installed under Linux, and I can find it through rpm-QA | grepllibxml2. then why should I prompt that error?
Should be libxml2-dev
apt-get install libxml2-dev
yum install libxml2-devel
