When I run the make of cyrus-imapd-2.4.17-caldav-beta9 get the following error:
In file included from httpd.c:68:0: httpd.h:48:25: fatal error: libxml/tree.h: No such file or directory compilation terminated.
I'm trying to install this beta version that supports calendars.
I have installed libxml2-dev.
apt-get install libxml2-dev
My operating system is Debian 7.
What am I forgetting?
