Cannot build GDB for arm-elf targets under cygwin...

Hello,

I'm trying to build insight and gdb for arm-elf targets from weekly
snapshots under cygwin-1.3.2, and it is impossible over the last one
month.

Host system: PC 'running' Windows 2000 (SP2) and with the lastest cygwin
release (cygwin-1.3.2, with gcc-2.95.3-5) installed.

The file .../insight+dejagnu-200106XX/gdb/remote-rdi.c doesn't compile.

The first error found was...

gcc -mwin32 -c -g    -I. -I/src/gdb/insight+dejagnu-20010619/gdb

This error is an obvious lack of parenthesis in the line 183 of the
host.h file...

But, even correcting the error, I get the following...

declaration of `arm_rdi_wait'
make[1]: *** [remote-rdi.o] Error 1

This error came because the prototype (line 80) and the implementation
(line 518) of the funcion 'arm_rdi_wait' in the "remote-rdi.c" file are
different.

In this point, before trying to modify the source code again, I decide
to ask to GDB list what is the most wise choice for my arm-elf debugger
(even because I'll need the RDI target!). Any sugestions???


Thanks in advance,

[Fernando Nasser]

Of course, you will need the patch... :-)

I have attached it this time.

I put together rproxy, which is in essense exteneded gdbserver, look at
gbd section on my web site http://world.std.com/~qqi

Also, if you are talking about threads support over remote GDB 
protocol there is some stuff there.

The only caveat there is that in the coming update I am going to change
licensing from GPL to BSD.

Dear Fernando,

After applying the patch in the "insight+dejagnu-20010619", it has
compiled fine!

Thank you very much!!!
