I've tried to install NTK on both a Raspberry Pi 3 and an Ubuntu 16.04 distro, so as to install Non, and both times it fails with
Checking for 'gcc' (C compiler) : /usr/bin/gcc Checking for 'g++' (C++ compiler) : /usr/bin/g++ Checking for program 'pkg-config' : ['/usr/bin/pkg-config'] Checking for 'x11' : not found The configuration failed (complete log in /home/pentney/ntk/build/config.log) It seems to be looking for a x11.pc file that isn't there - from build/config.log: Checking for 'x11' ['/usr/bin/pkg-config', '--cflags', '--libs', 'x11'] err: Package x11 was not found in the pkg-config search path. Perhaps you should add the directory containing `x11.pc' to the PKG_CONFIG_PATH environment variable There is no x11.pc file on either the Raspbian or the Ubuntu systems I tried this in, both of which are plain out-of-the-box installations that definitely have X11 and pkg-config installed and working. It doesn't appear to be in /usr/local/lib/pkgconfig or any alternative site, either. I don't see how the NTK package would ever install on many conventional Linux distributions. Am I missing something? Thanks, Bill
