Compilation with Intel oneAPI: Many warnings #244
Description
When installing boost with Intel oneAPI using the recommended way (bootstrap), the compiler gives the following warning
These options as listed are not supported.
For more information, use '-qnextgen-diag'.
option list:

For CMake, this is not an issue because the new, LLVM-based compiler identifies as IntelLLVM, not Intel (https://cmake.org/cmake/help/latest/variable/CMAKE_LANG_COMPILER_ID.html) and, hence, the options are not added here:

As far as I can see, Boost.Build does not discriminate between the legacy Intel compiler and the newer LLVM-based one - both are identified as
intel-linux(on Linux platform). So there is no way I could add these flags for the legacy compiler but not the newer one.I can see you've already created an issue for
b2to support the new compiler. Until that issue is resolved, there's nothing I can do in Boost.Log.In the meantime, you can patch your local Boost by removing the compiler options that don't work.

yes, unfortunately the PR at
b2is stuck because there is no test setup for Intel compilers.As far as I see, the flags specific to
boost.logonly disable warnings. So my suggestion would be to simply remove them to reverse the behavior: Instead of showing warnings for new compiler versions, show (other) warnings for old compiler versions. Unfortunately, one would still get the warning about-ipwhich is caused byb2.
