Is this still an issue with current Amazon cloud service?  I believe the Amazon build of ncurses is/was broken.  See the following output from both Fedora 26 and CentOS 7:
{noformat}
$ ldd /usr/lib64/libncurses.so.*.*
	linux-vdso.so.1 (0x00007ffca2f3a000)
	libc.so.6 => /lib64/libc.so.6 (0x00007ff6e1804000)
	libdl.so.2 => /lib64/libdl.so.2 (0x00007ff6e1600000)
	libtinfo.so.6 => /lib64/libtinfo.so.6 (0x00007ff6e13d4000)
	/lib64/ld-linux-x86-64.so.2 (0x00007ff6e1e01000)
{noformat}

In addition if I create a C program source mytest.c with a minimal main() function and run the following:
{noformat}
$ gcc mytest.c -o mytest -lncurses
$ ldd mytest
	linux-vdso.so.1 (0x00007ffc267b7000)
	libncurses.so.6 => /lib64/libncurses.so.6 (0x00007fe3c6d1c000)
	libtinfo.so.6 => /lib64/libtinfo.so.6 (0x00007fe3c6af0000)
	libc.so.6 => /lib64/libc.so.6 (0x00007fe3c671b000)
	libdl.so.2 => /lib64/libdl.so.2 (0x00007fe3c6517000)
	/lib64/ld-linux-x86-64.so.2 (0x00007fe3c6f44000)
{noformat}

As you can see linking with {{-lncurses}} caused my linker to implicitly include {{-ltinfo}} because ncurses requires it.  I believe the fact that Amazon did not do this was a bug in Amazon Linux, not Asterisk.

> Seems that the configure does not correctly include the -ltinfo into the NCURSES_LIB variable.
