Xilinx has their own rollup of an arm cross compiler they call PetaLinux. (IIRC it's an older variant of Yocto/OpenEmbedded). So that whole mess I have installed in /opt/Xilinx/Petalinux/<someversion>/complete-toolchaindirectory. Xilinx wants you to set an ENV var to point to that directory above so all it's canned scripts like "petalinux-build" work. With other programs like openntp and htop, I've made a semi-custom script that sets up stuff I need and looks like this: > #!/bin/sh > # > # This file helps set up just about any external project to use the > Zynq/Petalinux install/build tree. > # It really needs to be set to a current zynq build directory...

That's how configure for screen gets run. The logfile I sent you is what I get with the default 'configure' that's included in screen-4.6.2.tar.gz It looks like the configure script has been set to bail on cross compiling in general. And not being an autoconf person, that's where I'm stuck. -Ben p.s. The target is a Xilinx Zynq SoC with a dual-core ARM-A9 CPU running (uname -a): Linux uZed 4.0.0-xilinx #8 SMP PREEMPT Wed Feb 7 21:08:10 CST 2018 armv7l GNU/Linux
