Re: [Boost-users] [release] Boost 1.68.0 Beta 1 -> warnings in filesystem, locale, thread, stacktrace, container

Boost - Dev mailing list
Hi,

I have tested 1.68.0 on linux x86_64 with the following compilers:
- g++ 8.2.0,
- clang++ 5.0.2,
- mingw-w64 + g++ 8.2.0 cross compiling to windows 32 bits,
- mingw-w64 + g++ 8.2.0 cross compiling to windows 64 bits,
- clang++ 5.0.2 cross compiliing to OSX 10.9 32 bits,
- clang++ 5.0.2 cross compiliing to OSX 10.9 64 bits.

I did not find any major issue. Just those warnings while building the
libraries:

* filesystem (g++ 8.2.0 and clang++ 5.0.2 on linux x86_64):

libs/filesystem/src/operations.cpp: Dans la fonction « int
{anonymous}::readdir_r_simulator(DIR*, dirent*, dirent**) »:
libs/filesystem/src/operations.cpp:2126:18: warning: « int

            ^~~~~~~~~~

* locale (many more than that one about deprecated std::auto_ptr):
I wonder when auto_ptr will be removed but it would be nice to change
it to unique_ptr.

                            ^~~~~~~~

* thead with mingw w64 cross compiling to windows 32 bits on linux
x86_64 with g++ 8.2.0:
I guess this warning is due to the fact that time_t is 32 bits on
windows 32 bits so this looks dangerous to me.

libs/thread/src/win32/thread_primitives.cpp: Dans la fonction «

many locations with this warning:

Suggest filing issues in github for each repository affected in order to
track these to resolution.
