Support for Intel oneAPI missing

[MarDiehl]

I'm reposting the issue from bfgroup/b2#413 here because the lack of response.

Environment and version details

• Operating System+version: Arch Linux
• Compiler+version: Intel oneAPI 2024.2.1
• Shell: zsh
• B2 Version: B2 5.2.1 (OS=LINUX, jobs=8)
• B2 Configuration: Output of b2 --debug-configuration in your project.
  not added because it uses gcc.

Brief problem description

Options defined in https://github.com/bfgroup/b2/blob/3c0f5630157c3db1025b54c2f6da25cf234b8e20/src/tools/intel-linux.jam are incompatible with LLVM-based Intel compilers:

• -ip is not supported anymore
  • https://github.com/bfgroup/b2/blob/3c0f5630157c3db1025b54c2f6da25cf234b8e20/src/tools/intel-linux.jam#L216
• -use-pch should be -include-pch or -pch-use
  • https://github.com/bfgroup/b2/blob/3c0f5630157c3db1025b54c2f6da25cf234b8e20/src/tools/intel-linux.jam#L262
  • https://github.com/bfgroup/b2/blob/3c0f5630157c3db1025b54c2f6da25cf234b8e20/src/tools/intel-linux.jam#L273
• pch-create should be -Xclang -emit-pch -o (https://www.intel.com/content/www/us/en/developer/articles/technical/building-boost-with-oneapi.html)
  • https://github.com/bfgroup/b2/blob/3c0f5630157c3db1025b54c2f6da25cf234b8e20/src/tools/intel-linux.jam#L293
  • https://github.com/bfgroup/b2/blob/3c0f5630157c3db1025b54c2f6da25cf234b8e20/src/tools/intel-linux.jam#L303
• the Fortran compiler is called ifx, not ifort
  • https://github.com/bfgroup/b2/blob/3c0f5630157c3db1025b54c2f6da25cf234b8e20/src/tools/intel-linux.jam#L298

Steps to reproduce the issue

Install Boost with

./bootstrap.sh --prefix=/tmp/boost
./b2 install --without-python --without-graph_parallel --without-mpi cxxstd=17  toolset=intel-linux  link=shared address-model=64 architecture=x86 runtime-link=shared

Actual behavior summary

The compiler gives warnings and errors and installation of a few files fails.
A few example errors are shown

intel-linux.compile.c++ bin.v2/libs/log/build/intel-linux-linux/release/x86_64/cxxstd-17-iso/threading-multi/visibility-hidden/trivial.o
icpx: command line warning #10430: Unsupported command line options encountered
These options as listed are not supported.
For more information, use '-qnextgen-diag'.
option list: 
	-ip
	-wd177,780,2196,1782,193,304,981,1418,411,734,279

...skipped <pbin.v2/libs/math/build/intel-linux-linux/release/x86_64/cxxstd-17-iso/threading-multi/visibility-hidden>acoshl.o for lack of <pbin.v2/libs/math/build/intel-linux-linux/release/x86_64/cxxstd-17-iso/threading-multi/visibility-hidden>pch.pchi...

   intel-linux.compile.c++.pch bin.v2/libs/math/build/intel-linux-linux/release/x86_64/cxxstd-17-iso/threading-multi/visibility-hidden/pch.pchi

Expected behavior summary

b2 should support the most recent Intel C++ compiler (icpx)

-ip is not supported anymore
-use-pch should be -include-pch or -pch-use
pch-create should be -Xclang -emit-pch -o

These have been fixed in spack (patch). I've been meaning to push them upstream, but I guess now is a good time. I can submit a PR here, unless you're working on one.

the Fortran compiler is called ifx, not ifort

Huh. I don't know why that hasn't been encountered in spack builds. As of 4e62a3e , the ony Fortran file I can find is ./numeric/odeint/performance/fortran_lorenz.f90. Clearly, it's needed. I'll add that to my TODO for spack.

ifort exists in parallel and was the preferred compiler in the first oneAPI releases. But now, ifx is the default and iforts removal has been scheduled.

I can do that, but would mainly use code from your spack package. Let me know if that would be ok.

Ah, ok. That would explain it. Do you happen to know what version added ifx?

Of course! Let me know if you have any other questions about the patches there (there are lots).

It was there since the release of oneAPI (https://fortran-lang.discourse.group/t/intel-releases-oneapi-toolkit-free-fortran-2018/471). It reached feature parity with the old compiler in the 2023.0.0 release: https://fortran-lang.discourse.group/t/intel-fortran-2023-launch/4929

Closing, because boostorg/build#739 seems to be the right place for this issue
