boost 1.83.0 on macOS Sonoma doesn't build boost_locale.a

[pisajew]

I'm building on a silicon Mac and cross-compiling to x86_64 (however tried with arm target, and the result is the same). Output of b2 command:

The Boost C++ Libraries were successfully built!

but there is no libboost_locale.a in staging.

Noticed the same issue today on CentOS 6.

Worked around by patching file "libs/locale/build/Jamfile.v2", changing line

exe has_iconv : $(TOP)/build/has_iconv.cpp ;

to

obj has_iconv : $(TOP)/build/has_iconv.cpp ;

That is likely a different issue then as in the initial report iconv is found: - iconv (separate) : yes [2]
With your workaround you basically skip testing if it requires linking against libiconv. I Suspect for you both iconv (separate) and iconv (libc) are "no"? You might need to set ICONV_PATH as documented.

@pisajew Looks like the compiler you are using is lacking C++11 support. See e.g. cxx11_noexcept : no. Check the config.log as this looks odd as appearently Clang 15 is used which should default to a higher standard.

@Flamefire

I checked, the linking is OK: if I build it manually with gcc has_iconv.cpp -o has_iconv.cpp.exe, it gets the symbol iconv_open from /lib64/libc.so.6. I wanted to debug what happens inside the failing command configure.builds has_iconv : $(properties) : "iconv (libc)", but I couldn't figure out how can I do that. (Can you advice how to do that?)

I can submit a separate issue for this if preferred.

[pisajew]

Strange indeed. If I checkout master boost_locale builds correctly. It is just for version tag 1.83.0 where it's not being built (sad as I need that one compiled). For version 1.83.0 here is the relevant output from config.log:

but if I rerun the command manually adding correct standard option, it works:

I've ended up manually specifying -std=c++11 for cxxflags in project-config.jam, which does the job for me. As the problem doesn't exist on master I think this workaround is good enough and I'm closing this issue now.

[Flamefire]

Ok so I guess that Clang is older and/or has C++98 as the default standard.

Note that you can pass cxxstd=11 to b2 instead
