Where can I find information about the meaning of compiler flags?

[majo]

Hey There,
I started with reading sources of simple plugins today, but I want to learn about all the gory hardware-specific details rockbox has to offer. It would be a great help to me if I knew where I could look up the meaning of all the compiler flags (such as HAVE_LCD_BITMAP).

Any hints where I could find information? In the code base or somewhere else (in the config script)?

Greetings,
majo

Hi,

Whilst I'm sure people here will help if they are able, more devs tend to hang out on IRC or read the developers mailing list than in the forums.

It would be a great help to me if I knew where I could look up the meaning of all the compiler flags (such as HAVE_LCD_BITMAP).

This is not a compiler flag, this is a preprocessor macro. Speaking of HAVE_LCD_BITMAP, this is defined if the target has a bitmap lcd. Macros (or constants definitions as this) are used to distinguish between players. Have a look at firmware/export/*-config.h

Thanks. This was exaclty the information I was looking for :-)
