Re: How to PROVIDE boost-python


Emily
 

Hi Laurent - 

Unfortunately I don't have full control over the repo that's using boost_python-mt so I'm not sure I can switch it right now. 

I realize this is not a long-term solution, as I'll need to update that code (and my OS) to python3 soon, but for now I've just copied the boost recipe from this commit  to my own layer, and added a BBMASK to the openembedded-core's boost recipe. This seems to work, except I get a QA error from the commit I'm using for the boost recipe now:

ERROR: boost-1.63.0-r1 do_package: QA Issue: boost: Files/directories were installed but not shipped in any package:
  /usr/lib/libboost_numpy.so.1.63.0
Please set FILES such that these items are packaged. Alternatively if they are unneeded, avoid installing them or delete them within do_install.
boost: 1 installed and not shipped files. [installed-vs-shipped]
ERROR: boost-1.63.0-r1 do_package: Fatal QA errors found, failing task.
ERROR: boost-1.63.0-r1 do_package: Function failed: do_package

I found a log that mentions this exact error, and also mentions a patch that fixes it - I've tried and thus far failed to find that patch. I'm not sure if this will actually work, but I thought I'd check and see if anyone had any ideas. 

Thanks,
Emily

Also as Quentin suggested it might be needed to remove the "-mt"
suffix, but I see it in the do_install() method of the "boost" recipe
for revision 1.64.

Kind regards, Laurent.
