To do so, a few dependencies have been imported: * external/bsd/lutok * external/mit/lua * external/public-domain/sqlite * external/public-domain/xz The Kyua framework is the new generation of ATF (Automated Test Framework), it is composed of: * external/bsd/atf * external/bsd/kyua-atf-compat * external/bsd/kyua-cli * external/bsd/kyua-tester * tests Kyua/ATF being written in C++, it depends on libstdc++ which is provided by GCC. As this is not part of the sources, Kyua is only compiled when the native GCC utils are installed. To install Kyua do the following: * In a cross-build enviromnent, add the following to the build.sh commandline: -V MKBINUTILS=yes -V MKGCCCMDS=yes WARNING: At this point the import is still experimental, and not supported on native builds (a.k.a make build).
