Problem compiling Sage 7.6 from source

[Bernardo Feijoo]

Hello, I'm trying to build Sage 7.6 from source and it fails due to "Error installing package gcc-5.4.0". I'm running Ubuntu 17.04.

The relevant part of gcc-5.4.0.log follows.

Any help would be appreciated.

Thanks,
Bernardo.

When you are done debugging, you can type "exit" to leave the subshell.

you probably have a very new gcc (which version?), to which Sage is not yet ported, and it cannot build gcc 5.4.
you can downgrade gcc to a supported version.

or perhaps you do not have gfortran installed?

[Jeroen Demeyer]

Is the problem reproducible, i.e. does it happen again if you rebuild Sage?

Which compiler are you using?

[Bernardo Feijoo]

Thank you for your help, Dima.

I had version 6.3.0 of gcc installed. I tried to downgrade it but I was not able to. I also installed gfortran. Then I unistalled gcc, g++ and gfortran and installed them again (I was trying to install version 5.4.0, but failed again!).

Then I tried to install again and the installation stopped with an error about linbox. I just started it again and it seems to be progressing past linbox, so I think it's making progress. I'm just gonna keep trying.

Thanks again.
Bernardo.

[Bernardo Feijoo]

Thank you for your help Jeroen.

No, it's not reproducible. See my answer to Dima. Using gcc 6.3.0.

This suggests a hardware problem of some sort, most likely bad memory. I
strongly suggest to run a memtester on that machine.
