Building gdb on 64bit solaris

Building gdb on 64bit solaris

[Chu, Josh]

I have compiled gcc for 64bit solaris and attempted a compile of gdb.
I ran ./configure followed by 'make' and the compilation stops when trying
to compile core-sol2.c.
Here's my output :
...

Any idea why I am getting these errors?  Is this a known problem when
compiling 64bit solaris?
Thanks!

Could you please download than try GDB 5.2 or better a current snapshot 
of GDB.  See http://sources.redhat.com/gdb/current/ .  From other 
comments, it apparently doesn't build.  However, if you can post the 
details or look closer, it may be possible to figure out what is going 
wrong.

Ok, I downloaded 5.2, and everything built fine for 64-bit (although I'm
still going to have to modify source code to make this work with EDG
demangling)
Here's the steps I followed (ksh):

1) export CC='gcc -m64'
2) ./configure --prefix=<INSTALL DIR>
3) make
4) make install

This worked just fine.  I will be working on getting 5.2 to work with the
Kai C++ compiler so it can demangle the names properly, and I will mail that
to the Intel/Kai folks so they can hopefully post that on a website
somewhere for any Kai C++/KCC users
Thanks again

RE: Building gdb on 64bit solaris

[Chu, Josh]

Well one thing I did try was to comment out the offending lines in
core-sol2.c :
(from function fetch_core_registers, commenting out lines 63-87) :

...
      /*
      else if (core_reg_size == sizeof (struct regs))
        {
#define gregs ((struct regs *)core_reg_sect)
          *(int *) &registers[REGISTER_BYTE (0)] = 0;

          memcpy (&registers[REGISTER_BYTE (G1_REGNUM)], &gregs->r_g1,
                  15 * REGISTER_RAW_SIZE (G1_REGNUM));
          *(int *) &registers[REGISTER_BYTE (PS_REGNUM)] = gregs->r_ps;
          *(int *) &registers[REGISTER_BYTE (PC_REGNUM)] = gregs->r_pc;
          *(int *) &registers[REGISTER_BYTE (NPC_REGNUM)] = gregs->r_npc;
          *(int *) &registers[REGISTER_BYTE (Y_REGNUM)] = gregs->r_y;

          {
            int sp;

            sp = *(int *) &registers[REGISTER_BYTE (SP_REGNUM)];
            if (0 != target_read_memory (sp,
                                      &registers[REGISTER_BYTE (L0_REGNUM)],
                                         16 * REGISTER_RAW_SIZE
(L0_REGNUM)))
              {
                warning ("couldn't read input and local registers from core
file
\n");
              }
          }
        }
      */
...

I then tried to rebuild and it compiled and linked just fine.  Of course
these lines are very critical to gdb, and it is unable to read the 64-bit
executable if the lines are commented-out.
Does anyone know if this code could be altered so the below error doesn't
occur?

Andrew, I'll give a shot at the latest, but in any case I'll be in bad shape
since I'm using a patched version of gdb for the KAI c++ compiler, which
happens to only support gdb 5.0...worst case is I'll have to modify the new
source myself.
Thanks again
