Hello, I spent the last five days trying to get sage --gdb to work on Arch Linux, but I couldn't get it to work. Here is what I tried:
git clone https://github.com/sagemath/sage.git cd sage export SAGE_DEBUG=yes make -j4 ./sage -i gdb when the last command prompted > =========================== WARNING =========================== > You are about to download and install the experimental package > gdb-8.2. This probably won't work at all for you! There > is no guarantee that it will build correctly, or behave as > expected. Use at your own risk! > =============================================================== > I confirmed it. After that, I tried executing ./sage --gdb which resulted in $ ./sage --gdb > GNU gdb (GDB) 8.2 > ... > > Reading symbols from python...(no debugging symbols found)...done.Install > pygments for colorized source code. > Python was not compiled with debug symbols (or it was stripped).

Is is possible that sage doesn't like my cython installation, or does sage use it's own cython verrsion? -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
