Wishlist: 64 bit on linux

[Russ Lewis]

I recently upgraded to an Athlon 64, and installed Fedora Core 5 with 
the AMD64 kernel.  This broke my D applications, because Phobos is 
released as a 32-bit library.  I am writing this partly as an FYI for 
anybody else who hits this problem, and partly as a request to Walter


TO MAKE THINGS WORK:

You need to pass -m32 to gcc.  Most importantly, you need to do that at 
the link step.  So, if you're like me, and you used to use dmd to link, 
then you'll see something like this:
	dmd ...FILES... -ofcebu
	gcc ...FILES... -o cebu -lphobos -lpthread -lm
	/usr/bin/ld: skipping incompatible /usr/lib/libphobos.a when searching 
for -lphobos
	/usr/bin/ld: cannot find -lphobos

Basically, you need to change your Makefile to call gcc directly, and 
pass it the -m32 argument:
	gcc -m32 ...FILES... -o cebu -lphobos -lpthread -lm

Also, if you link with any C files, then you need to pass -m32 to gcc 
when you build those as well.



FOR WALTER:

I don't know how much this would take, but it would be really nice if 
you released a 64-bit version of Phobos, as well as the 32-bit one.  I 
suppose that this would mean that the compiler would need to be able to 
produce 64-bit ELF files.

But, I realize that this is probably low on the priority list.  That is 
probably as it should be.
