This fork requires C++17.
Embed binary files and resources (such as GLSL Shader source files) into C++ projects.
Include this repository in your CMake based project:
git submodule add https://github.com/cyrilcode/embed-resource.git lib/ embed-resource
Then add to your CMakeLists.txt for your project:
include_directories(lib/embed-resource)
add_subdirectory(lib/embed-resource)
Now you can add your resources, by calling the provided embed_resources() function in your CMakeLists.txt file. In this fork you have to choose a name after the path (e.g. to avoid name collisions with the same file names from different directories):
embed_resources(MyResources
shaders/vertex.glsl shader
shaders/frag.glsl shader
)
Then link to your binary by adding the created variable to your add_executable statement:
add_executable(MyApp ${SOURCE_FILES} ${MyResources})
In your C++ project you can access your embed resources using the Resource class
provided in Resource.h. Here's an example:
#include <iostream>
using namespace std;
#include "Resource.h"
int main() {
Resource text = LOAD_RESOURCE(frag_shader);
cout << string(text.data(), text.size()) << endl;
return EXIT_SUCCESS;
}
NB: In this fork to reference the file, use the the chosen name and the file name without extensions (- will be replaced with an underscore _).
So, in this example, the symbol name is frag_shader.
This uses ideas from
this blog post
which included the Resource class and macro idea. Unfortunately, the use of ld command didn't work on OSX.
So, instead, I've used a simple C++ executable that does the same conversion, based on ideas from
this Stack Overflow question.
