Re: [PyMOL] Error aroused when install pymol from source

[Thomas H. <tho...@sc...>]

Hi Yeping,

3 options:

1) Get msgpack 2.x sources from https://github.com/msgpack/msgpack-c and tell the C++ compiler about the headers, e.g. with:

export CXXFLAGS="-I/tmp/msgpack-2.1.2/include"

2) If you have installed msgpack 1.x, which is a dynamic library, also install msgpack-devel and build pymol with --use-msgpackc=c

3) Build pymol with --use-msgpackc=no which disables MMTF load support

Note that msgpack version 0.x is not supported by PyMOL.

Hope that helps.

Cheers,
  Thomas
