Hi Guys, I want to cross compile the ofono for ARM target. So i executed configure file with following arguments #./configure --host=arm --libdir=/usr/lib/madde/linux-i686/sysroots/meego-core-armv7l-madde-sysroot-1.1.2-fs/usr/lib --prefix=/home/$myname/Desktop/ofono_For_ARM/binaries --includedir=/usr/lib/madde/linux-i686/sysroots/meego-core-armv7l-madde-sysroot-1.1.2-fs/usr/include It is giving config related error message configure: error: signalfd support is required What it does mean? To cross compile the ofono for ARM. What are the dependencies are required Thanks Addu T.R
