I managed to build gdb-4.17 in FreeBSD 4.0, here's how to do it:
1) gdb-4.17/configure --host=i386-unknown-freebsdelf4.0
Have to specify the host explicitly, otherwise it doesn't realize
it needs to use ELF.
2) in gdb-4.17/Makefile, add "-DSVR4_SHARED_LIBS" to definition of CFLAGS
3) in gdb-4.17/gdb/solib.c, add #include "elf/common.h"
(after #include "elf/external.h")
4) in gdb-4.17/gdb/infptrace.c, add #define U_REGS_OFFSET 0x1fa8
I figured out this number the hard way by searching all the valid PT_READ_U
addresses and comparing the results with PT_GETREGS - found locations
where eip and esp values matched up. Doubtless there's a better way to
get the right value.
Then it should all build (and perhaps work). The same hacks probably apply
to gdb-4.18 and gdb-current (but so far gdb-4.17 is the most useful version
I've seen for debugging C++).
