I'm just curious: are you using this kind of libraries in embedded
Linux systems? What kind of applications do they do?

Is it possible to use an http:// URL instead for cloning? It usually
works better for people behind stupid corporate firewalls/proxies.

qhull seems to be using quite a bit of C++ code. Maybe it should
depends on BR2_INSTALL_LIBSTDCPP ?
Can you try building it with the following minimal configurations:
http://autobuild.buildroot.org/toolchains/configs/free-electrons/br-arm-basic.config
http://autobuild.buildroot.org/toolchains/configs/free-electrons/br-arm-full-nothread.config
http://autobuild.buildroot.org/toolchains/configs/free-electrons/bfin-uclinux.config
it is useful to check a few dependencies.
Thanks!
Thomas
