At least, gcc-4.6.3, the last official gcc for Ubuntu-12.04, could build gcc-4.8.5 manually (without shared libstdc++, so confused dependency could be avoided). And, I could build cmake-3.11.0 by it. Now I'm checking "make test". If you can give the preferred prefix to install gcc-4.8.5 + cmake-3.11.0, I would be able to a tarball of the binaries. but please prepare some virus + malware checking :-) Regards, mpsuzuki > Anyway, CMake seems to already know how to ship binaries that work > across Linux distros.
