Help request: Linker error coming from entry.o

[Samwhamtymam]

Hi everyone,

I have been wanting to try out bgfx for a while now and have gone through the usual build process all okay. However, now that I come to try compile a simple main.cpp with all the release libraries linked, I run into a linker error which says the following.

Undefined symbols for architecture x86_64:
  "__main_", referenced from:
      entry::main(int, char const* const*) in libexample-commonRelease.a(entry.o)
ld: symbol(s) not found for architecture x86_64

I can see that this is one of the bgfx libraries complaining, but i'm not sure what I can do fix it as it doesn't seem to need any links to external frameworks. I'm sure this is just me being foolish so I posted it here rather than in the issues section. Please don't hesitate to ask for more information if needed.
Thanks a bunch.

You're missing ENTRY_IMPLEMENT_MAIN:

bgfx/examples/00-helloworld/helloworld.cpp

Lines 132 to 137 in f6e0db1

	ENTRY_IMPLEMENT_MAIN(
	ExampleHelloWorld
	, "00-helloworld"
	, "Initialization and debug text."
	, "https://bkaradzic.github.io/bgfx/examples.html#helloworld"
	);

Thanks for the help,

I tried to use this and the error still came. The solution was to also define ENTRY_CONFIG_IMPLEMENT_MAIN as 1 before as entry.h will automatically define it as 0, just in case anyone has the same issue.

Could I also ask, what is bgfx using as the working directory? I'm having trouble loading the shaders for the cubes01 example, it seems to be a filepath issue.

bgfx_proj[81646:2220561] ../../../examples/common/bgfx_utils.cpp(75): Failed to load shaders/metal/vs_cubes.bin.

Sorry for the trouble,
Thanks again :)

Working directory for examples is examples/runtime.
