Using version 4.0, I'm experience the same issue as #943

I'm trying to build it myself (i.e: without CMake provided by the cpputest project) on the target (ESP32 IDF)

I'm getting
undefined reference to `_ZN10UtestShell28assertUnsignedLongLongsEqualEyyPKcS1_jRK14TestTerminator

and it is the only that linker complains.

I tried this

#define CPPUTEST_LONG_LONG_DISABLED
#define CPPUTEST_USE_LONG_LONG 0
#include <CppUTest/TestHarness.h>
#include <CppUTest/CommandLineTestRunner.h>

Update:
I can build an empty test group

TEST_GROUP(Name_Group) {
  void setup() override {
  }

  void teardown() override {
  }
};

but as soon as I place an empty TEST it fails about
testShell28assertUnsignedLongLongsEqual

TEST(Name_Group, test) {
}

It looks there are two assertUnsignedLongLongsEqual functions with different signatures?
