Under Ubuntu 18.04 I followed the instructions here: https://gcc.gnu.org/wiki/InstallingGCC https://gcc.gnu.org/wiki/InstallingGCC And everything went well until the `make` step - it just blew up with a million compiler errors. I did the same thing under OpenSUSE and it built just fine.

  With C++, a million errors are oftentimes one error a million different ways.

    Its one error after name mangling.

    Flashback... When trying C for the first time, I ported a ~300 line Pascal program. I had read C syntax for some time, and the program was rather simple so I felt confident in the job. After transcribing the ~300 lines I tried to compile for the first time: 3728 errors and warnings... I read through the code and everything looked correct, so I gave up. Picked it up again some weeks later. Turned out that I had, by force of habit, erroneously added a semicolon at the end of macro definition on line 3. Fixing that it compiled flawlessly. At the time I was also unaware that I was actually using a C++ compiler, djgpp, which I'm sure did the error count no favors.

      Ah djgpp, rhide and allegro, that was my gateway drug.

        Same here! A while back I found some of my old Allegro games from a high school CS class (choked back chunks), and with little effort got them to compile on modern macOS. It was quite nostalgic.

  Weird. Usually when it passes configure stage, then you're more or less good to go. Usually it's just this sequence: wget gcc... whichever untar it and go into the directory within that directory ./contrib/download_prerequisites outside of that directory create a build directory, go in there and do a config. I usually do (for example in 9.1 case, but it has been the same forever now): ../gcc-9.1.0/configure --prefix=<my_home_dir>/tools/gcc-9-1-0 --enable-languages=c,c++,ada --disable-multilib --enable-checking=release --with-pkgversion='GCC Keyframe' For Ada you have to have an Ada enabled compiler already, so omit ada and after that it's simple make and then make install I also have functions in my .zshrc with which I set envs so I can easily switch between gcc versions (and linkers) and that's it.
