Description
A few days ago I started having issues upgrading qBittorrent
, at the time the revision updated libtorrent-rasterbar @2.0.10_1+python312
was still not available. As the latter became available and I get the same errors trying to build that, I now note that I seem to have either an issue with boost181
or with both libtorrent-rasterbar
and qBittorrent
. Consequently, I tried a forced rebuild of boost181
and I also tried various +
options. I now have the following at my disposal:
port -v installed boost181 The following ports are currently installed: boost181 @1.81.0_10+clang13+cmake_scripts+no_single+no_static+python312+regex_match_extra requested_variants='+clang13+cmake_scripts+regex_match_extra' platform='darwin 19' archs='x86_64' date='2024-04-05T11:17:14+0200' boost181 @1.81.0_10+clang17+cmake_scripts+no_single+no_static+python312 (active) requested_variants='+clang17+cmake_scripts' platform='darwin 19' archs='x86_64' date='2024-04-09T12:51:37+0200' boost181 @1.81.0_10+clang17+cmake_scripts+no_single+no_static+python312+regex_match_extra requested_variants='+clang17+cmake_scripts+regex_match_extra' platform='darwin 19' archs='x86_64' date='2024-04-04T13:23:17+0200' boost181 @1.81.0_10+clang17+mpich+no_single+no_static+python312 requested_variants='+clang17+mpich+python312' platform='darwin 19' archs='x86_64' date='2024-03-25T14:39:17+0100'
Neither of which results in a working build of libtorrent-rasterbar
or qBittorrent
. However, since every single failed build point is making a reference to boost
, I have a strong feeling that this might indeed be mainly an issue with boost181
and not the dependent ports. I did see another user having an issue with building specifically libtorrent-rasterbar
at #69569 that was due to a python mismatch. It would be interesting to hear if that user had any luck after rebuilding with +python312
.
Searching for answers, another issue also popped up, as referenced in #68518 regarding C++11 or later. As can be seen here: https://en.cppreference.com/w/cpp/types/result_of, one possible culprit may be the deprecation of std::result_of
as of C++20 (if I managed to decipher the references correctly) and that instead something along the lines of std::invoke_result
should have been used instead. I am thus making a final test, rebuilding boost181
with +clang11
as I found some hints (https://github.com/opencv/opencv/issues/21109) at std::result_of
might be available if using pre-Clang 13, but as expected that did not help either. In the Portfile C++14 seems to be requested:
# ensure that compiler is using C++14 mode configure.cxxflags-append -std=c++14
so, as it is before C++20, I did not expect this to be a problem.
I am not really sure what changed between the revisions, as I have libtorrent-rasterbar @2.0.10_0+python312 requested_variants='' platform='darwin 19' archs='x86_64' date='2024-04-04T14:31:31+0200'
successfully built here.
An example of the multiple errors of the same type thrown for both ports, referencing boost:

Summary: | Boost181 provokes build errors in libtorrent-rasterbar and qBittorrent → boost @1.76: error: no member named 'result_of' in namespace 'boost' |
You are likely right that this is caused by you using a newer compiler that is capable of C++20. Note however that your error comes from the boost port @1.76, not the boost181 port. Everything using boost should be using the separate versioned boost ports, but for some reason we still have the unversioned boost port at an old version. It would be nice if we could get rid of that, since its mere presence can cause other port builds to fail.

That is somewhat odd though as both libtorrent-rasterbar
and qBittorrent
depend on boost181
:
# port -v deps libtorrent-rasterbar Full Name: libtorrent-rasterbar @2.0.10_1+python312 Build Dependencies: path:bin/cmake:cmake Library Dependencies: path:lib/libssl.dylib:openssl, port:python312, port:boost181 # port -v deps qBittorrent Full Name: qBittorrent @4.6.4_0+gui+webui Build Dependencies: path:bin/cmake:cmake, port:pkgconfig, port:clang-16, path:libexec/qt6/lib/QtUiTools.framework/QtUiTools:qt6-qttools, port:boost181 Library Dependencies: port:libtorrent-rasterbar, path:lib/libssl.dylib:openssl, port:zlib, path:libexec/qt6/lib/QtCore.framework/Versions/A/QtCore:qt6-qtbase, path:libexec/qt6/translations/qt_ar.qm:qt6-qttranslations, path:libexec/qt6/lib/QtSvg.framework/Versions/A/QtSvg:qt6-qtsvg
I guess the port could depend on boost181 @1.81.0_10
while the code itself references an unversioned boost @1.76
. I see that boost
indeed depends on boost176
, so that could potentially have something to do with the situation. However, I did also rebuild that one as well on the off chance that it did make an impact. I now have the following:
# port -v installed boost176 The following ports are currently installed: boost176 @1.76.0_10+clang14+no_single+no_static+python311 requested_variants='+clang14' platform='darwin 19' archs='x86_64' date='2023-12-20T12:36:44+0100' boost176 @1.76.0_10+clang17+cmake_scripts+no_single+no_static+python312+regex_match_extra (active) requested_variants='+clang17+cmake_scripts+regex_match_extra' platform='darwin 19' archs='x86_64' date='2024-04-04T12:33:15+0200'
and I have tried both variants to no avail. I guess I could build a version with an "older" Clang and +python312
and see what happens, but I do not hold very high hopes.

Replying to Gandoon:

libtorrent-rasterbar
andqBittorrent
depend onboost181
:
I am aware.
Back before we had versioned boost ports (boost176, boost181, etc.) that install their headers and libraries into nonstandard directories, we had the boost port which installed its headers and libraries into the standard directories. Gradually ports were migrated from the unversioned boost port to the versioned ones. However, because the boost port installs into standard directories, its headers and libraries might be found by build systems even though we were intending them to use a different versioned boost port's headers and libraries. The problem can be worked around by using trace mode (unless you use macOS 13 or newer on Apple Silicon) or by deactivating the boost port before building. The problem would go away if the boost port were deleted.

I see.
Unfortunately I have vtk @9.3.0_0+ffmpeg+python311+qt5+xdmf
installed that depends on the unversioned boost
, which is why it was installed in the first place. As I mentioned, I tried by building a version of boost176
with Clang-14, a configuration known to have worked historically for the mentioned for me broken ports. That solved the build issue for libtorrent-rasterbar
but it did still break qBittorrent
. I was unsure if it would have worked if I had deactivated the unversioned boost
, but as qBittorrent
still failed I tried that route with the currently active boost181 @1.81.0_10+clang17+cmake_scripts+no_single+no_static+python312
. With the unversioned boost
deactivated in the end qBittorrent
built as intended even though boost @1.81
was built with +clang17
. I expected that maybe I would have to revert to e.g. +clang14
for boost181
as well, but it worked. I guess I found a workaround. However, I was, and still am a little unsure if the current state will cause any trouble. As it hasn't before I guess it will be fine. To be sure I did force a rebuild of libtorrent-rasterbar
with a deactivated unversioned boost
and it seems to build as intended. It remains to be seen if it the ports works as intended.
This was somewhat unintuitive, but at least solvable. As it sounds as if the unversioned boost
should be deprecated, and that there are more than one port that boost
broke, maybe libtorrent-rasterbar
, qBittorrent
, and any other port that shows this behaviour should have their respective Portfiles report a conflict if an unversioned boost
is installed and active? And obviously, vtk +xdmf
(and possibly others) needs to change dependency to the versioned ports. I will have to check if I really need the vtk +xdmf
variant. If not, I could potentially get rid of the unversioned boost
and not run into this issue again.
Thank you for your input.

Two quick notes:
As there recently was made available an updated qBittorrent @4.6.5_0+gui
, I tried again and I got the same error as before with the unversioned boost
active. A deactivation of this let qBittorrent
build without problems.
In addition, it seems as if my vtk @9.3.0_0+ffmpeg+python311+qt5+xdmf
does not really care if the unversioned boost
is active or not, at least not during a rev-upgrade
despite that it lists port:boost
as a dependency. Thus I assume that any linking is working as it should, presumably against my installed boost176 @1.76.0_10+clang14+cmake_scripts+no_single+no_static+python312
. I assume that the next time vtk
is updated (which seems due), especially if the library dependency on port:boost
is still there, I will see what happens. I expect a complaint about dependencies not being met during build, but as the library is there and seemingly linked to, not having boost
there won't have any implications in real life. As far as I can see, the port just soft-links select /opt/local/lib/libboost*
instances to the boost176
installation anyway. I am guessing that it may be the presence of libraries and includes in /opt/local/lib
and /opt/local/include/boost/
in the top-level directories that throws qBittorrent
builds off. It expects boost181
but looks in the mentioned locations, finding boost176
content instead of /opt/local/libexec/boost/1.81/
. Anyway, this issue seem to be a minor inconvenience more than anything.
