Hi, ok, talking to myself here...
It seems that the problem is that the symbol is redefined incompatibly. It's bound to get redefined, as gdb sources include both core windows headers and core native platform headers. Since I'm building on x86_64, the size_t is defined 64 bit in platform headers, hence the conflict. While that speaks about obviously improper use of headers, I've added "-m32" to the gdb CFLAGS, and that seems to have fixed that problem. However. On some mixed i386/x86_64 systems, there is this preprocessor code in asm header files: #ifdef __x86_64__ # include <asm-x86_64/errno.h> #else # include <asm-i486/errno.h> #endif On mine(CentOS), it's more complicated: # if defined __x86_64__ # include <asm-x86_64/errno.h> # elif defined __i386__ # include <asm-i386/errno.h> # else # warning This machine appears to be neither x86_64 nor i386. # endif Since the gdb building process undefines any __ix86__ defines, a lot of asm includes just don't get included. Not sure the reason for undefining those __ix86__ defines, but I ended up having to define a lot of missing constants, like EINTR, SOL_SOCKET, etc. (so, yeah, I get a lot of those neigher 64 nor i386 warnings during compilation). Funny, how both asm/errno.h come from the same kernel version 2.6.18, but first one was quoted from 2.6.18-6-k7 on debian, and mine is 2.6.18-92.1.10.el5 on CentOS 5.1 Not sure what the proper course of actions there is for all that. Thanks, Pawel.
