first code won't run

[sephris]

I hope it's okay to dig this thread out, as I'm encountering follow-up issues after adding pthread to the library names in the Visual GDB settings (maybe that's the problem?). Here's the output from VS:

So there are errors regarding everything that starts with "vc_dispmanx_..." and then there's "C:\Dev\GameProgrammingPi\Project1\main.cpp(325): error : undefined reference to `bcm_host_init'" ... I'm completely clueless with Linux, so I could use a hint about what goes wrong here.

Using Visual Studio 2017. The "Hello World" text program already worked.

Thank you in advance!


EDIT:
Okay, I solved it, I thought that all I had to enter in the library names were those:

• GLESv2_static 
  
• EGL_static 
  
• vchiq_arm 
  
• vcos 
  
• khrn_static 
  
• pthread
  

But that's not all of it, because I forgot to add bcm_host, so the whole thing now looks like this: 



And after that, I finally saw the triangle in all its glory!

Great to hear you fixed it.

Well done
