Same failure with gcc11 too.

UPD. Boost 1.79 builds fine on identical setup with gcc12. Only Boost 1.80 fails.

grisumbras · 2022-10-18T16:44:06Z

We test gcc 11 and 12, although not on Apple. Can you give me the full list of compiler flags being used? b2 -d+2 prints commands being executed by the build system.

@grisumbras Here is the full log.

One thing to check here is whether an older Boost is in the include path. The above would happen in that case, as the older version of Boost.System won't support the necessary conversion from boost::system::error_code to std::error_code.

pdimov · 2022-10-18T22:49:39Z

MacPorts seems to have 1.76 (in /opt/local/include/boost), so if that's installed, it would be new enough for things to mostly work even if the 1.76 headers are picked up occasionally.

All Boost versions through 1.79 build fine. Only 1.80 errs out.

@pdimov I believe Macports takes care to keep Boost versions separated, but to be on the safe side, I can deactivate all Boost versions and try building 1.80 again.

UPD. No change, so it is not an older header problem.
boost180_gcc12.log

sdarwin · 2022-10-19T00:47:17Z

Including old versions of boost headers sounds like a possible explanation.

Searching on a test machine with xcode and brew gcc installed, there weren't any large boost directories. Used the locate command. The word "boost" appears, here and there, in the filesystem, but nothing resembling a full installation of boost, unless it was somehow compressed and hidden in another file.

pdimov · 2022-10-19T01:20:15Z

My other theory is that for some reason the macro BOOST_NO_CXX11_HDR_MUTEX is being defined on this configuration. This leads to Boost.System disabling the <system_error> interoperability: https://github.com/boostorg/system/blob/9a6d79b84147854aa919644b56b8553f5a2bedb8/include/boost/system/detail/config.hpp#L22-L24

This can happen when libstdc++ is compiled as single-threaded, but I have no idea why this would be the case.

Or, by looking at the Config source, it can also happen if timed mutexes aren't available: https://github.com/boostorg/config/blob/2543ff139707a32cc421b62c9d65bb4d9c965b3e/include/boost/config/stdlib/libstdcpp3.hpp#L462-L465

barracuda156 · 2022-10-19T01:23:45Z

My other theory is that for some reason the macro BOOST_NO_CXX11_HDR_MUTEX is being defined on this configuration.

@pdimov Is this something introduced with Boost 1.80? (No failure with any earlier version, I just rebuilt 1.79, 1.78, 1.76 and 1.71.)

pdimov · 2022-10-19T01:29:37Z

It is. Earlier versions implemented conversions to std::error_code differently, without needing std::mutex, but with a one-time allocation that caused problems with leak checkers. 1.80 uses a different mechanism.

barracuda156 · 2022-10-19T04:44:11Z

@pdimov Aha, apparently this is exactly what breaks 1.80: boostorg/config#399

grisumbras · 2022-10-19T08:28:43Z

The error is related to Boost.System. Apparently, there's a recurring issue on Apple that old version of Boost.System that's already installed on the system is picked up rather than the intended 1.80 version. Can you check that this is not what's happening?

@grisumbras I already did – deactivating all Boost versions prior to building 1.80. No change.
The problem seems to be related to the issue referred above with libstdc++.

grisumbras · 2022-10-19T08:47:49Z

Oh, my browser haven't pulled the discussion before I posted. Looks like you've figured it out!

barracuda156 · 2022-10-19T08:52:55Z

@grisumbras Yeah, just someone has to fix that now :)

pdimov · 2022-10-19T09:19:12Z

Until we figure out how to properly fix this, you should be able to compile Boost 1.80 by defining BOOST_SYSTEM_HAS_SYSTEM_ERROR manually by adding define=BOOST_SYSTEM_HAS_SYSTEM_ERROR to the b2 command line.

Users of Boost 1.80 however might have to do that as well, although it should mostly work.

pdimov · 2022-10-19T09:35:51Z

Maybe I can use BOOST_NO_CXX11_HDR_CONDITION_VARIABLE to check for <mutex> instead of the proper macro. It's ridiculous, but looks like it ought to work for this case.

Or maybe you could just patch Boost.Config and comment out https://github.com/boostorg/config/blob/2543ff139707a32cc421b62c9d65bb4d9c965b3e/include/boost/config/stdlib/libstdcpp3.hpp#L464, because it seems to be entirely wrong for GCC 11/12 as those should provide timed_mutex on MacOS. :-)

@barracuda156 is the problem still present?

pdimov · 2022-11-21T09:55:35Z

Boost.Config has been fixed, so it shouldn't be.

grisumbras · 2023-07-17T15:48:30Z

Closing this as it should be fixed now

Boost 1.81 certainly builds fine with GCC.
