Here's the commit where the dependency was introduced, back in 2013:

https://github.com/cctbx/cctbx_project/commit/d9821259e8aa5a3614cfba4ec51bb4d2ade39e84

Here's the cctbx dependency chain:

$ libtbx.show_module_dependencies cctbx

 cctbx depends on scitbx chiltbx

   scitbx depends on boost_adaptbx omptbx boost

     boost_adaptbx depends on tbxx

       tbxx has no libtbx_config

     omptbx depends on boost_adaptbx boost

       boost has no libtbx_config

   chiltbx has no libtbx_config

I agree with you Luc, but I'm not sure how to proceed here.  Should map_writer be taken out of iotbx or should cctbx be made dependent on iotbx?

Hi,

C:\Users\luc\Documents\Developer\cctbx\modules\cctbx_project\cctbx\maptbx\SConscript, line 5-8:

env = env_base.Clone(
  SHLINKFLAGS=env_etc.shlinkflags,
  LIBS=["iotbx_xplor", "cctbx_sgtbx_asu", "cctbx", "omptbx", env_etc.libm]
)

This is not supposed to be: the cctbx shall be usable with only what’s defined in its libtbx_config.

Best wishes,

Luc
