Hi,

When i tried make, i got many python errors. I confirmed the python is correctly installed....any idea on this? Thanks a lot!

BTW, i mean the make of go-python-master for installation

[sbinet]

it seems the compilation is missing a link to libm.
are you sure pkg-config knows about Python?

[xhaoxiong]

are you resolve it ?

Not sure I'm going to give a shot
