Hi Michael,

Sorry for not writing clearly.
I gave the configurartion as ppc-ibm-eabi and it took that configuration
the configure command was successful.

when i gave make
i got the same error as i mensioned yerterday i.e.

when it was trying to link all .o and libraries to get gdb.exe
it got unresolved reference to "_ _imp_ _ _ctype_ "
in file "readline.o"
this error is repeated many times for the same file.

I checked the file readline.c there is no refrence to "_ _imp_ _
 _ctype_ " present there. This symbol is generated by compiler while compiling
readline .c

Just now i tried the configuration with ppc-unknown-eabi and
i am getting same error after make.

i.e. unresolved refrence to "_ _imp_ _ _ctype".

Is the version gdb4.18 is compiling ? properly for pc as host and powerpc as
target ?.
Should i use some other release !!!


Thanks
Sudhanshu

Try:

     powerpc-eabi

or

     powerpc-unknown-eabi

since as you noted powerpc-ibm is treated as powerpc-ibm-aix.

You are having a problem with mismatched libraries due to downloading of
a cygwin snapshot.  You should either search the cygwin mailing list
archives to find out how to resolve this or send mail to
cygwin@sourceware.cygnus.com.

Alternatively, you could try downloading the new net release (check the
cygwin web page:  http://sourceware.cygnus.com/cygwin/ )

I could solve this problem.
There were some .h files make was picking up from /usr/local/include
that was causing the problem.

Thanks for the information.

Cross compilation with AIX as a target has never been supported in the GNU
tools (mainly due to nobody contributing the code).  What I suspect is
happening is the AIX tools are expecting to find the shared library information
in a fixed location, and since it doesn't find it, it assumes you have no
shared libraries.

As Eris says, powerpc-eabi is the mode for embedded PowerPC.  Note, it uses a
completely different ABI than the AIX compilers.  It also has the quirk that it
doesn't include newlib by default when linking unless you use one of the
supported board options such as -mmvme.

This isn't quite right.  Hopefully you aren't trying to run aix on your
target board (I really hope not).  The configuration you want is
target=powerpc-eabi, e.g. --target=powerpc-eabi.

GDB for PC windows NT

[Sudhanshu_Tewari]

Hi ,
Is anybody aware of any working release of
GDB for PC windows NT as host and IBM-powerpc as target board.

As with 4.18  I  tried compiling but getting some compilation as follows errors.

Set1:

config :
host = i686-pc-cygwin
target = i686-pc-cygwin

Then i got error at final linking stating some clipbpard functions are
unresolved.
I commented those functions and i could get working executable.

Set2:
config
host = i686-pc-cygwin
target = powerpc-ibm-aix
_
I am getting undefined refrence to aix_process_lineos
multiple undefined refrence to __imp__ctype  in readline.c ( Here problem is
that this __imp___ctype is generated by gcc it is present only in .o file )
So set2 is the one i require and i am stuck here.

Thanks
Sudhanshu
