 Posted: Thu Dec 03, 2020 7:56 pm Post subject: rebuild of the boost-dependent ecosystem [SOLVED] |
 |
|
Today's rebuild due to the standardization of Python 3.8, gives me the following in the elog:
| Code: | # cat dev-libs:boost-1.72.0-r2:20201203-172213.log
LOG: postinst
Boost.Regex is *extremely* ABI sensitive. If you get errors such as
undefined reference to `boost::re_detail_107200::cpp_regex_traits_implementation
<char>::transform_primary[abi:cxx11](char const*, char const*) const'
Then you need to recompile Boost and all its reverse dependencies
using the same toolchain. In general, *every* change of the C++ toolchain
requires a complete rebuild of the boost-dependent ecosystem.
See for instance https://bugs.gentoo.org/638138 |
Huh?
I guess users are just supposed to know how to do that, but I don't have a clue. The reference in bugs.gentoo.org wasn't helpful.

EDIT: this message is alway printed
| Code: | pkg_postinst() {
elog "Boost.Regex is *extremely* ABI sensitive. If you get errors such as"
elog
elog " undefined reference to \`boost::re_detail_$(ver_cut 1)0$(ver_cut 2)00::cpp_regex_tr

elog "requires a complete rebuild of the boost-dependent ecosystem."

I think that warn you if another package return this message error you can try rebuild boost

Thank you for replying.
But it doesn't read rebuilt boost. It reads: "requires a complete rebuild of the boost-dependent ecosystem." How does one
rebuild the boost-dependent ecosystem? Why wait for trouble after such a strong warning?

"If you get errors such as..."
Did you get such an error? |

The warning is there because you might have upgraded boost. A re-emerge is not an upgrade.
AFAIK the boost ecosystem is boost and boost-build

Very good -- thank you. I guess badly overstated warning. I'll stop worrying about it.

As I read it, that message talks about rebuilding Boost and reverse dependencies (stuff that links to Boost libraries, I assume) in case a C++ toolchain upgrade creates problems with it -which apparently isn't the case at the moment-. I suppose that means when e.g. GCC is upgraded (and therefore libstdc++).
An easy way to get an idea about what needs Boost is emerge -pcv | grep 'requires.*dev-libs/boost'. |

You can done this also with equery equery d boost | awk -F' ' '{print "="$1}' | xargs emerge -pv
