Bug 153428 – gdk error, compiled for big endian, machine is little endian

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description slavko glamocanin 2006-10-30 04:03:09 UTC]

I have an AMD64 installation (freshly installed gentoo 2006.1), for which i emerged java and azureus. i got the beforementioned endiannes error and found a possible explanation on : http://bugs.scribus.net/view.php?id=1316 . after that i edited /usr/include/X11/Xarch.h and recompiled gtk+ which fixed the error. in Xarch.h i removed some ifdef and would supply it with this bug report if i knew how:)

What changes did you make to Xarch.h?  A diff would be a bit more useful.

i removed some architecture stuff not related to mine (which is amd64).

i think that this problem is handled with poor style and somehow some other arch gets precedence over amd64 for endiannes. its really hard to see anything in this coding /ifdef/ style, but ok, i guess its the easiest to handle it this way.

i will also add the diff you requested.

im not sure but the problem might be here:

> #if defined(__QNXNTO__)
> #if defined(i386) || defined(__i386__) || defined(__x86__)
> #define BYTE_ORDER LITTLE_ENDIAN
> #else
> #define BYTE_ORDER BIG_ENDIAN
> #endif
> #endif 

as i see it, the 386/x86 checks are for the x86 arch (x86_64 is obviously missing), but i dont think QNXNTO is defined.

the Xarch diff file

this works if you have and x86 linux machine but surely breaks some archs. well it works for me:)

I have an AMD64 install and I don't see this issue.  Perhaps there was something wacky with your configuration when you compiled gtk+ for the first time?  Can you use the default Xarch.h and see if you can reproduce this?
