C++ Coding Magpi#66

[Brian Beuken]

I'm trying to follow along with these articles but ran into an issue with MagPi#66.

Where you describe adding the references to the libs in Code:Blocks, I was not able to locate the file names that are listed in the article.  I'm running a RasPi 3B+ with the latest Raspibian kernel 4.14.71-v7+.

This is what I found:
No GLESv2_static.a only libGLES_static.a
No EGL_static.a only libEGL_static.a
no vchiq_arm.a only libvchiq_arm.so
no vcos.a only libvcos.so


Also, when compiling the code (modified from MagPi #65) I get the following error:
-------------- Build: Debug in HelloWorld (compiler: GNU GCC Compiler)---------------

Oh, I got it.  I had to add -lpthread to the Other linker options.

the library names always start with libXXX 

we just refer to them without the lib in your project build options

take a look at this image attached to see how you set up the libs  and the other to see how you set up the search paths for the linker
