Building from source, cmake fails because of mGBA errors

[Chuckaluphagus]

I'm on Ubuntu 20.04, so I build from source.  This has worked fine in the past.  I went to update and try out the fancy new Internal GBA functions, and cmake fails due to the absence of necessary files related to mGBA:

Code:

CMake Error at Externals/mGBA/CMakeLists.txt:3 (add_subdirectory):
 The source directory

   /home/charles/games/dolphin-emu/Externals/mGBA/mgba

 does not contain a CMakeLists.txt file.


CMake Error at Externals/mGBA/CMakeLists.txt:6 (target_compile_options):
 Cannot specify compile options for target "mgba" which is not built by this
 project.


CMake Error at Externals/mGBA/CMakeLists.txt:13 (add_library):
 add_library cannot create ALIAS target "mGBA::mgba" because target "mgba"
 does not already exist.

What would be the solution to this?

You'll have to run this in the Dolphin repo:

git submodule update --init

We'll try to get this added to the build instructions soon.

You rock.  Thank you, built and running now.

I was getting the following error and your git command fixed it!

Code:

CMake Error at Externals/spirv_cross/CMakeLists.txt:49 (add_library):
 Cannot find source file:

   SPIRV-Cross/GLSL.std.450.h

 Tried extensions .c .C .c++ .cc .cpp .cxx .cu .mpp .m .M .mm .ixx .cppm .h
 .hh .h++ .hm .hpp .hxx .in .txx .f .F .for .f77 .f90 .f95 .f03 .hip .ispc


CMake Error at Externals/spirv_cross/CMakeLists.txt:49 (add_library):
 No SOURCES given to target: spirv_cross

If you're getting "spirv" errors from the master branch from git (linux builds) run this:
as recommended by @JosJuice...

Code:

git submodule update --init
