[sage-devel] Re: Building sage 8.9 from source on macOS Mojave failure

TeXlive is installed normally in /usr/local/ so I may be facing new problems by moving it out of its default location but I will take the time to try to sort this out. Thanks so much! On Monday, October 14, 2019 at 9:23:57 PM UTC+2, S. Diop wrote: > > I am experiencing failure building sage 8.9

Re: [sage-devel] Re: Building sage 8.9 from source on macOS Mojave failure

My guess is that you installed TeXLive directly, instead of using Homebrew. (Same probably applies to ImageMagick, and perhaps Spell, Octave...) I'd have erased everything in /usr/local, and started from scratch - but perhaps that's too costly for you. In any case, I'd start by installing TexLive

Hi Dima: you are certainly right: it seems that homebrew did not successfully install libgd. When I try to reinstall it it stuck at the postinstall stage. Here are the logs of my tentatives. Could you help with this? bash: > brew install libgd Updating Homebrew... ==> Auto-updat

Re: [sage-devel] Re: Building sage 8.9 from source on macOS Mojave failure

for some reason libgd configure failed to detect the presence of libpng. as you are using Homebrew anyway, a quick fix would be to install its libgd, then uninstall Sage's libgd by doing make libgd-clean followed by ./configure make build On Wed, 16 Oct 2019, 20:05 S. Diop, wrote: > I

Thanks. One sees there ImportError: dlopen(/Applications/sage-8.9/local/lib/python2.7/site-packages/sage/matrix/matrix_mod2_dense.so, 2): Symbol not found: _gdImageCreateFromPng so something is wrong with libgd (and possibly with libpng) Could you post the main config.log of this build, as well

For what it's worth, if you don't mind installing a secondary package manager (https://nixos.org/nix/download.html) you can also use the nix package on debian. Using the unstable channel (rolling release) you can already use sagemath 8.9. You can use pre-build binaries or build from source. I
