Hi folks!
Maybe someone can help me.
I try to building lib through cinterop and there are complex numbers. On macosX64, macosArm64, mingwX64 everything is well, but on linuxX64 I get follow exception:

16:22:47   Exception in thread "main" org.jetbrains.kotlin.konan.KonanExternalToolFailure: The /mnt/agent/system/.persistent_cache/konan/dependencies/llvm-11.1.0-linux-x64-essentials/bin/clang++ command returned non-zero exit code: 1.
16:22:47   output:

At the same time, openblas has processing for different standards:

#if ((defined(__STDC_IEC_559_COMPLEX__) || __STDC_VERSION__ >= 199901L || \
      (__GNUC__ >= 3 && !defined(__cplusplus))) && !(defined(FORCE_OPENBLAS_COMPLEX_STRUCT))) && !defined(_MSC_VER)
  #define OPENBLAS_COMPLEX_C99
#ifndef __cplusplus
  #include <complex.h>
#endif
  typedef float _Complex openblas_complex_float;
  typedef double _Complex openblas_complex_double;
  typedef xdouble _Complex openblas_complex_xdouble;
...
#else
  #define OPENBLAS_COMPLEX_STRUCT
  typedef struct { float real, imag; } openblas_complex_float;
  typedef struct { double real, imag; } openblas_complex_double;
  ...
#endif
