[sage-devel] issues with gurobi

I recently installed gurobi 8.0.1 and identified py3 issues. See ticket 28206. I also installed the last version of gurobi, 8.1.1, for OSX, but I cannot use it with Sagemath as I don't find something like libgurobi81.so Does anyone know what to do ?

[sage-devel] nauty_geng and subprocess : how to ensure the termination of the subprocess ?

While playing with graphs.nauty_geng(...), I noticed that the geng subprocess might remain active after a ctrl-C, and even after existing the current sagemath session. This is not always the case, but it happens frequently. Try this for instance (I'm using debug mode to quickly get an output):

Re: [sage-devel] Optional and experimental packages

File splay.c has changed in nauty (at least in 26r12). The main difference is - static SPLAYNODE* - SPLAY_DELETE(SPLAYNODE **to_root, SPLAYNODE *p) + void + SPLAY_DELETE(SPLAYNODE **to_root, SPLAYNODE *p) With this change, I can do gcc -O3 -std=c89 buckygen.c -o buckygen So upstream must be
