Failed to compile the last version 2022.0.0 with MinGW under Windows 10 : Error in CMake "math cannot parse the expression"

[fdiedler]

Summary

Hi,

I was not able to compile the oneTBB library for the last version 2022.0.0 (it works fine with the previous version 2021.13.0)

Version

Version 2022.0.0

Environment

Windows 10
CMake 3.30.2
mingw64-13.2.0 for GCC and G++ compiler

gcc -v
Using built-in specs.
COLLECT_GCC=gcc

Expected Behavior

No errors in CMake

Steps To Reproduce

Just load the source file in CMake, press Configure and select "MinGW makefiles" and "Use default native compilers" (assuming you have in your PATH environment the right compiler otherwise select "Specify native compilers" and choose the path to GCC and G++)

Error similar to #1556. I guess the GAS version has a prefix or a suffix on MinGW.

@Jhuighuy Thanks for you reply :)
Is there any quick workaround for that ?
Thanks

@fdiedler Looks like I've made a misleading comment.

The issue is not related to the GAS version (no easy workaround here by the way, submitted a PR). It looks like there is no /dev/null on MinGW (or it does not behave like on Posix), but I am not very familar with MinGW generally and do not have a Windows machine to test, unfortunately.

For a quick workaround, I think, here you can replace

execute_process(
    COMMAND ${CMAKE_COMMAND} -E env "LANG=C" ${CMAKE_CXX_COMPILER} -xc -c /dev/null -Wa,-v -o/dev/null
    OUTPUT_VARIABLE ASSEMBLER_VERSION_LINE_OUT
    ERROR_VARIABLE ASSEMBLER_VERSION_LINE_ERR
    OUTPUT_STRIP_TRAILING_WHITESPACE
    ERROR_STRIP_TRAILING_WHITESPACE
)

with something like

set(_empty_file "${CMAKE_BINARY_DIR}/empty.c")
file(TOUCH "${_empty_file}")
execute_process(
    COMMAND ${CMAKE_CXX_COMPILER} -Wa,-v -c "${_empty_file}" -o "${_empty_file}.o"
    OUTPUT_VARIABLE ASSEMBLER_VERSION_LINE_OUT
    ERROR_VARIABLE ASSEMBLER_VERSION_LINE_ERR
    OUTPUT_STRIP_TRAILING_WHITESPACE
    ERROR_STRIP_TRAILING_WHITESPACE
)
file(REMOVE "${_empty_file}")
file(REMOVE "${_empty_file}.o")
unset(_empty_file)

If it helps, a PR can be submitted.

@Jhuighuy Thanks, seems to works just have a message :

[ 11%] Linking CXX shared library ....\gnu_13.2_cxx11_64_relwithdebinfo\libtbb12.dll
C:\mingw64-13.2.0\bin\ar.exe: CMakeFiles/tbb.dir/address_waiter.cpp.obj: plugin needed to handle lto object

What does it means ?

I also have an error while building tests :
