How to require only the extensions my system supports?

Hi,
If I use the Web service and I "add all" of the extensions - when I use the resulting file does the header #define macros for only the extensions available on my system?

In other words, If i try to do #ifdef GL_EXT_memory_object and I requested that extension but it is not available on my platform, will it be defined (incorrectly)?

The defines just allow you to check at compile time which extensions (and opengl versions) are potentially available. After loading/initilaizing glad you can check with GLAD_<name of extension> if the extension is available at runtime (= supported by the driver and loaded).

In your example:

// [initialize glad]
// ...

if (!GLAD_GL_EXT_memory_object) {
    die("GL_EXT_memory_object not supported!");
}

I hope this answers your question.
