Sorry for reviving this old thread, but I’m having the same problem.
ninja: error: '/home/anbj/.gmt/gmt/doc/scripts/images/GMT_RGBchart.ps', needed by 'doc/rst/source/_images/GMT_RGBchart.pdf', missing and no known rule to make it
Doing a dvc pull gives me this:
[... snip ...]
doc/scripts/images/GMT_base_symbols3.ps
doc/scripts/images/GMT_tut_11.ps
doc/examples/images/ex02.ps
Is your cache up to date?
<https://error.dvc.org/missing-files>
Has anyone built the docs recently with success?
I’ve tried on several computers, wiped the build directory, etc., but it does not help.
