[OT] unbelievable: #ifdef _OTHER_LIB_H

[Adam D. Ruppe via Digitalmars-d]

So my computer died on me again last week and I had to buy new 
hardware. I was forced to update the software to run the new 
hardware... and it is painful.

I hate all software and have learned that if I want a job done 
right, I have to do it myself. Rarely, I find other people's 
software is OK with some slight modifications, so I try to do 
that.

xterm is one example. I basically like it but it is ugly and 
stupid so needs a few fixes. As such, I maintain my own private 
fork of it.

I went ahead and compiled that on the new thing today.... and it 
failed. wait what?!


#ifndef _XLIB_H_
#error Please include <X11/Xlib.h> before "xutf8.h"
#endif


That's in the xterm source code. Yes, it depends on the presence 
of a particular include guard.

The X11 source apparently recently changed to:

#ifndef _X11_XLIB_H_
#define _X11_XLIB_H_


thereby breaking xterm... and blackbox... and who knows what 
else. This one was brought to my attention thanks to the #error 
directive. But there's certainly other things silently being 
compiled out now, as the program does not work correctly after 
fixing this.

Unbelievable.


Praise D's modules.


PS the fonts are all hideous on the new linux too. I should have 
just bought a Windows license.
