Hi! I made progress turning my optional old-style group cohomology spkg into a new style package (called "modres", to be added to Sage at some point) depending on another new-style package (called "meataxe", already part of Sage), both being wrapped by an OptionalExtension in the Sage library. Ale

[sage-devel] Sage depends on (system) libvpx?!

2016-08-16 Thread Luca De Feo
After a system upgrade my built-from-source sage install started crashing with the log message ImportError: libvpx.so.3: cannot open shared object file: No such file or directory and indeed my system update updated libvpx from 3.x to 4.x, while I can't find any trace of it in the sage/ folder
