I had a similar problem on 14.04 and solved it by installing gcc 4.9 (other version are also available) from the ubuntu-toolchain-r PPA.
This worked for me. YMMV: $ sudo add-apt-repository ppa:ubuntu-toolchain-r/test $ sudo apt-get update $ sudo apt-get install gcc-4.9 $ sudo apt-get install g++-4.9 When building CMake I set the CXX and CC variables at the command line $ CXX=g++-4.9 CC=gcc-4.9 ../path/to/bootstrap ...etc .. $ CXX=g++-4.9 CC=gcc-4.9 make install HTH Patrick On Thu, Apr 5, 2018 at 7:15 AM, Robert Maynard <robert.mayn...@kitware.com> wrote: > The official CMake binaries do the same thing as you and build with a > static libstdc++ and libgcc. > As far as dependencies we use static builds of those too, with most > being the version provided inside CMake, and an external openssl. > > You can find the more information on the exact flags we are using at: > https://gitlab.kitware.com/cmake/cmake/blob/master/ > Utilities/Release/linux64_release.cmake > > On Thu, Apr 5, 2018 at 3:09 AM, Eric Wing <ewmail...@gmail.com> wrote: > > Thanks for the responses.
