In order to use the C++17 include <filesystem>
I need gcc-9
package in my debian docker.
By default debian:latest
(aka 10 or buster) will install gcc 8.3.0
from the regular distro repo.
Is there any PPA, testing repo, whatever, where I can easily install a gcc-9
(or later) package (i.e. not build it from source)
Thanks !
note: need gcc-9 to have good C++17 <filesystem>
support.
GCC 9 Release note:
Using the types and functions in does not require linking with -lstdc++fs now.
src: https://gcc.gnu.org/gcc-9/changes.html
note2: CMake 3.16* doesn’t support any cxx_filesystem compiler feature AFAIK.

note: I added these line after the install of
build-essential
so technically the container install the "default" gcc then it is updated by the one in the testing repo...note2: Using
RUN gcc --version
I've gotgcc (Debian 9.3.0-11) 9.3.0

debian:10
