Hi all, I'm trying to build/install Free Switch on an Amazon EC2 server (Amazon Linux AMI 64-bit) and "./configure" keeps exiting with the following error : ./configure <snip> checking for the version of libcurl... 7.24.0 checking for libcurl >= version 7.13.0... yes checking whether libcurl is usable... no no checking for tgetent in -lncurses... no checking for tgetent in -lcurses... no configure: error: libtermcap, libcurses or libncurses are required! (notice the extra "no" on a line by itself) .... I have installed all the ncurses packages I can find, to no avail : rpm -qa | grep -E 'curses|ncurses|term|curl' ncurses-term-5.7-3.20090208.9.amzn1.x86_64 ncurses-libs-5.7-3.20090208.9.amzn1.i686 python-pycurl-7.19.0-8.7.amzn1.x86_64 libcurl-7.24.0-5.25.amzn1.x86_64 ncurses-base-5.7-3.20090208.9.amzn1.x86_64 ncurses-libs-5.7-3.20090208.9.amzn1.x86_64 ncurses-5.7-3.20090208.9.amzn1.x86_64 curl-7.24.0-5.25.amzn1.x86_64 ncurses-devel-5.7-3.20090208.9.amzn1.x86_64 libcurl-devel-7.24.0-5.25.amzn1.x86_64 .... I have been able to install succcessfully on a local CentOS machine and Rackspace CentOS 6.3 VM, I believe the issue is something specific to Amazon EC2 but I haven't been able to figure it out. Any suggestions for a fix/workaround would be appreciated. Thanks, Rob
