Attempts to build gcc 7.2 in CentOS 7 with devtoolset-7, fails

[mjsaltzman]

I am trying to build with binary-pkg on CentOS 7. I have SCL devtoolset-7 installed, which includes gcc-7.2 (including g++ and gfortran). I am trying to build the master branch of Sage. The script still tries to build it's own gcc-7.2 and terminates with an error. (The error is that ld can't find crti.o, but the point is that it shouldn't be building gcc-2.7 at all, since it is already using gcc-2.7 and gfortran-2.7 is installed.)

Looks like that worked, thanks. I think it would help if that was in the documentation someplace, if at all possible.

I'm hoping that this ticket is merged in the next beta.
