How to disable the check of flags (-fPIC)

[fripSide]

The fPIS flag is unsupported in embedded GCC and generates error messages. There is no meaning to check it. Can I disable the -fPIC check and suppress the error message?

checking for the linker (ld) ... arm-none-eabi-gcc
checking for flags (-fPIC) ... no
> arm-none-eabi-gcc "-fPIC"
checkinfo: @programdir\core\sandbox\modules\os.lua:249: d:/tools/iot/eclipse/gnu-mcu-eclipse/arm-none-eabi-gcc-9.2.1-1.1/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld.exe: d:/tools/iot/eclipse/gnu-mcu-eclipse/arm-none-eabi-gcc-9.2.1-1.1/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/lib\libc.a(lib_a-exit.o): in function `exit':

Here are my policies. I failed to find a correct policy to disable the compiler flags checks.
I have tried to disable the "check.auto_map_flags" in rules but it does not work.

$ xmake l core.project.policy.policies
{
  "platform.longpaths" = {
    description = "Enable long paths when building target or installing package on windows.",
    default = false,
    type = "boolean"
  },
  "check.target_package_licenses" = {
    description = "Enable check the compatibility of target and package licenses.",
    default = true,
    type = "boolean"
  },
  "check.auto_map_flags" = {
    description = "Enable map gcc flags to the current compiler and linker automatically.",
    default = true,
    type = "boolean"
  },
  "package.requires_lock" = {
    description = "Enable xmake-requires.lock to lock required packages.",
    default = false,
    type = "boolean"
  },
  "build.across_targets_in_parallel" = {
    description = "Enable compile the source files for each target in parallel.",
    default = true,
    type = "boolean"
  },
  "build.merge_archive" = {
    description = "Enable merge archive intead of linking for all dependent targets.",
    default = false,
    type = "boolean"
  },
  "check.auto_ignore_flags" = {
    description = "Enable check and ignore unsupported flags automatically.",
    default = true,
    type = "boolean"
  },
  "package.precompiled" = {
    description = "Enable precompiled packages.",
    default = true,
    type = "boolean"
  }
}

check.auto_ignore_flags

Thanks. I have solved it now. This option needs to be enabled. I used to keep it disabled in order to force add ldflags.

target:set("policy", "check.auto_ignore_flags", true)

-- force load flags
target:add("ldflags", cflags, {force = true})
target:add("ldflags", ldflags, {force = true})
