Re: [sage-devel] Note on building sagemath-8.2 with GCC 8.1.0

So, summing up, I tried compiling the library on Fedora 28 64bit, which ships with gcc 8.1 by default. I encountered 3 different issues, 2 already addressed by fidelbc and one more with python 3.6.1 While I resolved the issue with python2 in the same way fidelbc did, I couldn't find any

Did you run "make doc-clean" and "make doc"? It looks like it doesn't have the necessary reference information that the first pass of the docbuild usually generates. Best, Travis On Thursday, May 17, 2018 at 10:38:08 AM UTC-5, Paul Mercat wrote: > > Hi, > > I get the following error when I

On Fedora 28 (another gcc-8 system) Dario (my student) also had problem with building python3, as we were getting a broken crypt module. A remedy he found, after a lot of debugging, was to backport the patch from https://bugs.python.org/issue28503 (which uses crypt_r if available) On Thursday,

I have met this problem, which occurs when OpenSSL isn't available systemwide (there is a saga somewhere in sage-devel's archive, around spring 2017 IIRC...). I have personally checked that Sage's pip is (or was, at the time) unable to use SSL when compiled against Gnu TLS alone... This should

Actually in sage-on-gentoo I reduced that quite a bit. In vanilla we have "argv": ["/home/fbissey/sandbox/git-fork/sage-8.3.b0/local/bin/sage", "--python", "-m", "sage.repl.ipython_kernel", "-f", "{connection_file}”] That is, sage-devs go to quite some lengths to launch sage’s python with the

Re: [sage-devel] Note on building sagemath-8.2 with GCC 8.1.0

Dear F, Thanks! For Python 2.7-14 we will be switching for 2.7-15 that does cause any trouble with GCC 8.1.0. See [1]. For linbox, there is at least [2] opened (but no patch for the moment). BTW, when I did build Sage with 8.1.0 few times ago I also had troubles with fflas that you do not
