Sure, now a system version of libpng is used by default. We're trying to unvendor as much as possible from Sage the distribution, see https://trac.sagemath.org/ticket/27330 - something which is a necessary step towards make sagelib a "normal" Python library, which you could install by running pip. So, yes, if you have a stale library somewhere it might break the build, as it's not really possible to test on all the possible broken configurations. You may force building of libpng by doing ./configure --without-system-png before running make Hope this explains. > > On Wednesday, November 20, 2019 at 3:38:12 PM UTC-8, Dima Pasechnik wrote: >> >> you can do >> >> brew install libpng >> >> which would install libpng 1.6.37 into /usr/local/ >> (I think, by looking at >> https://github.com/Homebrew/homebrew-core/blob/master/Formula/libpng.rb) >> >> you can also install a lot of other homebrew packages, such as gmp, etc >> to account for more packages on https://trac.sagemath.org/ticket/27330 >> >> >> I've tweaked/wrote some Homebrew formulas to get flint and arb >> >> brew install dimpase/science/flint >> brew install dimpase/science/arb >> >> from https://github.com/dimpase/homebrew-science >> >> (probably many more can be done this way too) >> >> >> >> On Wed, Nov 20, 2019 at 11:22 PM Paul Masson <paulm...@comcast.net> wrote: >> > >> > I have Homebrew installed but have rarely used it so assumed it wasn't >> > part of the problem.
