Hello, since I am new in this fore, let me introduce myself:
My name is Sebastian Oehms and I worked as a mathematician in the 90th. I finished my mathematical career already in 1997 (after PhD), but in my leisure time, I still like to think about mathematics. My favorites belong to algebra and topology, especially algebras and groups being connected to the Artin braid groups and questions about polynomial link invariants. The principal opportunity to do this, is on my daily rides on the subway where I used to carry a (almost seven years old but mint colored) Acer ASpire AO-Happy net-book. In 2016 I installed LinuxMint 17.3 on it in order to work more with sage. Comfortably I can work on it with version 6.9 but 8.2 is still usable. Since that time I learned much about sage and surely I need to learn much more in order to help to improve it. But I think it's time to start with this attempt, right now. Currently, I have problems to build version 8.2.beta5 on three systems on which I am using sage: On each I got the following error: [gfortran-7.2.0] Host system: [gfortran-7.2.0] Linux SebaThinkPad 4.4.0-103-generic #126-Ubuntu SMP Mon Dec 4 16:23:28 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux [gfortran-7.2.0] **************************************************** [gfortran-7.2.0] Error: gcc is already installed [gfortran-7.2.0] Host system: [gfortran-7.2.0] Linux SonyVAIO 3.19.0-32-generic #37~14.04.1-Ubuntu SMP Thu Oct 22 09:41:40 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux [gfortran-7.2.0] **************************************************** [gfortran-7.2.0] Error: gcc is already installed [gfortran-7.2.0] Host system: [gfortran-7.2.0] Linux tchiboix 3.19.0-32-generic #37~14.04.1-Ubuntu SMP Thu Oct 22 09:37:25 UTC 2015 i686 i686 i686 GNU/Linux [gfortran-7.2.0] **************************************************** [gfortran-7.2.0] Error: gcc is already installed On the first host (ThinkPad on LinuxMint 18 Mate) the previous successful build was 8.2.beta4. But already for this I needed 2 attempts since I had the problem with giac-1.4.9.45 described before by David Coudert: https://groups.google.com/forum/#!topic/sage-devel/CHAgwg0spMg and which I could solve by the hint given by Francois Bissey (running "sage -f gcc" before running make again). On the second host (LinixMint 17.3 Cinnamon) the previous successful build was 8.2.beta2. Here I didn't do any attempts in the meantime. The third host is the Acer AO Happy (LinuxMint 17.3 Mate). The previous successful build here was 8.2.beta3. When I tried to build beta4 on this machine, I had the same problem as on the ThinkPad. The hint of Francois did not work here. The attached log-file belongs to the attempts on the ThinkPad! What can I do to run make successfully? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
