Re: [sage-devel] Building sage 9.0 fails in Centos 8

I just updated gcc, g++ and gfortran to 9.2.0 but ./configure still can not detect gcc but it detects gfortran. gcc-9.2.0 gdb-8.2 gf2x-1.2.p0 gfan-0.6.2.p1 gfortran-9.2.0 will not be installed (configure check) Also forcing i.e. ./configure --with-system-gcc , does not seem

typically this happens if you don't have g++ and gfortran installed on your system. On Wed, 15 Jan 2020, 21:17 Aria Shahverdi, wrote: > Thanks, Yes the portable edition is working fine. I am trying to build > from source and that is when it causes the problem. > > I looked more and it seems the

Thanks, Yes the portable edition is working fine. I am trying to build from source and that is when it causes the problem. I looked more and it seems there is an issue with gcc and it tries to build gcc although I have gcc-8.3 On Wednesday, January 15, 2020 at 4:11:25 PM UTC-5, Dima Pasechnik

Hi, I got the '*sage-9.0-Debian_GNU_Linux_10-x86_64.tar.bz2* ' from the website and am trying to install it on Centos 8. (I previously did the same procedure for sage 8.9 and it was successful). There is erro

Re: [sage-devel] Power series do not distinguish between different precisions!

We only store power series and p-adics to finite precision, so it's impossible to tell whether the mathematical objects underlying two elements in Sage are actually equal. In practice, the goal of a p-adic or power series computation is to determine some result approximately, since that's all that

Re: [sage-devel] Re: Build of 9.0 failed at R

Thanks to all those who replied, especially Eric. It seems clear the issue is/was with gfortran. I had not installed the system gfortran so I was using the sage one. I now have the system one (7.4.0, same as Eric). I'm not entirely sure how to ensure sage uses the system version (in principle I

[sage-devel] Power series do not distinguish between different precisions!

Dear all, obviously Sage does not distinguish between precisions of power series: sage: R. = PowerSeriesRing(ZZ) sage: O(t).is_zero() True sage: O(t) == O(t**2) True Similarly for p-adics: sage: O(3).is_zero() True sage: O(3) == O(3^2) True sage: This seems to be explicitly intended: def
