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

  • b2/src/tools/intel-linux.jam

    Line 216 in 3c0f563

    flags intel-linux.compile OPTIONS $(condition)/<optimization>speed : "-O3 -ip" ;

• -use-pch should be -include-pch or -pch-use

  • b2/src/tools/intel-linux.jam

    Line 262 in 3c0f563

    LD_LIBRARY_PATH="$(RUN_PATH)" "$(CONFIG_COMMAND)" -c -xc++ $(OPTIONS) $(USER_OPTIONS) -D$(DEFINES) -I"$(INCLUDES)" -use-pch"$(PCH_FILE)" -c -o "$(<)" "$(>)"

  • b2/src/tools/intel-linux.jam

    Line 273 in 3c0f563

    LD_LIBRARY_PATH="$(RUN_PATH)" "$(CONFIG_COMMAND)" -c -xc $(OPTIONS) $(USER_OPTIONS) -D$(DEFINES) -I"$(INCLUDES)" -use-pch"$(PCH_FILE)" -c -o "$(<)" "$(>)"

• pch-create should be -Xclang -emit-pch -o (https://www.intel.com/content/www/us/en/developer/articles/technical/building-boost-with-oneapi.html)

  • b2/src/tools/intel-linux.jam

    Line 293 in 3c0f563

    rm -f "$(<)" && LD_LIBRARY_PATH="$(RUN_PATH)" "$(CONFIG_COMMAND)" -x c++-header $(OPTIONS) $(USER_OPTIONS) -D$(DEFINES) -I"$(INCLUDES)" -c -pch-create "$(<)" "$(>)"

  • b2/src/tools/intel-linux.jam

    Line 303 in 3c0f563

    rm -f "$(<)" && LD_LIBRARY_PATH="$(RUN_PATH)" "$(CONFIG_COMMAND)" -x c-header $(OPTIONS) $(USER_OPTIONS) -D$(DEFINES) -I"$(INCLUDES)" -c -pch-create "$(<)" "$(>)"

• the Fortran compiler is called ifx, not ifort

  • b2/src/tools/intel-linux.jam

    Line 298 in 3c0f563

    LD_LIBRARY_PATH="$(RUN_PATH)" "ifort" -c $(OPTIONS) $(USER_OPTIONS) -D$(DEFINES) -I"$(INCLUDES)" -c -o "$(<)" "$(>)"

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.

Expected behavior summary

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