When I make, with:

  • C++ Compiler: Version 13.1.6 (at /usr/bin/clang++)

  • Cores to use: 12
  • Memory limit: 16384 MB

And it remind me that

jdk11u-dev-master/src/hotspot/share/jfr/periodic/jfrNetworkUtilization.cpp:59:30: error: too many arguments provided to function-like macro invocation assert(interfaces != NULL, "invariant");

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX12.3.sdk/usr/include/assert.h:98:9: note: macro 'assert' defined here #define assert(e) \

Which means the source codes of jdk use two arguments assert, but my Mac just support one argument assert.

In ./test/hotspot/gtest/unittest.hpp in the jdk11u source there is this comment and redefinition of assert:

// gtest/gtest.h includes assert.h which will define the assert macro, but hotspot has its
// own standards incompatible assert macro that takes two parameters.
// The workaround is to undef assert and then re-define it. The re-definition
// must unfortunately be copied since debug.hpp might already have been
// included and a second include wouldn't work due to the header guards in debug.hpp.
#ifdef assert
  #undef assert
  #ifdef vmassert
    #define assert(p, ...) vmassert(p, __VA_ARGS__)
  #endif
#endif

Somehow this has been broken for test/hotspot/gtest/jfr/test_networkUtilization.cpp... it appears to be that assert is getting redefined in one of the includes after unittest.hpp.

You can fix the compile by moving the #include of unittest.hpp down a bit, see this diff:
