@chapter Building the GNU Debugger

GDB is not currently RTEMS aware. The following configurations have been

successfully used with RTEMS applications:

@itemize @bullet

@item Sparc Instruction Simulator (SIS)

@item PowerPC Instruction Simulator (PSIM)

@item DINK32

@end itemize

Other configurations of gdb have successfully been used by RTEMS users

but are not documented here.

@section Unarchive the gdb Distribution

Use the following commands to unarchive the gdb distribution:

@example

cd tools

tar xzf ../archive/@value{GDB-TAR}

@end example

The directory @value{GDB-UNTAR} is created under the tools directory.

@c

@c  GDB GNAT Patch

@c

@section Apply GNAT Patch to GDB

@ifclear GDB-GNATPATCH

No GNAT specific patches are required for @value{GDB-VERSION} to

support @value{RTEMS-VERSION} and @value{GNAT-VERSION}.

@end ifclear

@ifset GDB-GNATPATCH

Apply the patch using the following command sequence:

@example

cd tools/@value{GDB-UNTAR}

zcat archive/@value{GDB-GNATPATCH} | patch -p1

@end example

Check to see if any of these patches have been rejected using the following

sequence:

@example

cd tools/@value{GDB-UNTAR}

find . -name "*.rej" -print

@end example

If any files are found with the .rej extension, a patch has been rejected.

This should not happen with a good patch file.

To see the files that have been modified use the sequence:

@example

cd tools/@value{GDB-UNTAR}

find . -name "*.orig" -print

@end example

The files that are found, have been modified by the patch file.

@end ifset

@c

@c  GDB RTEMS Patch

@c

@section Apply RTEMS Patch to GDB

@ifclear GDB-RTEMSPATCH

No RTEMS specific patches are required for @value{GDB-VERSION} to

support @value{RTEMS-VERSION}.

@end ifclear

@ifset GDB-RTEMSPATCH

Apply the patch using the following command sequence:

@example

cd tools/@value{GDB-UNTAR}

zcat archive/@value{GDB-RTEMSPATCH} | patch -p1

@end example

Check to see if any of these patches have been rejected using the following

sequence:

@example

cd tools/@value{GDB-UNTAR}

find . -name "*.rej" -print

@end example

If any files are found with the .rej extension, a patch has been rejected.

This should not happen with a good patch file.

To see the files that have been modified use the sequence:

@example

cd tools/@value{GDB-UNTAR}

find . -name "*.orig" -print

@end example

The files that are found, have been modified by the patch file.

@end ifset

@section GDB with Sparc Instruction Simulation (SIS)

@subheading Make the Build Directory

Create a build directory for the SIS Debugger

@example

cd tools

mkdir build-sis

@end example

@subheading Configure for the Build

Configure the GNU Debugger for the

Sparc Instruction Simulator (SIS):

@example

cd tools/build-sis

../@value{GDB-UNTAR}/configure --target-sparc-erc32-aout \

    --program-prefix=sparc-rtems- \

    --disable-gdbtk \

    --enable-targets=all \

    --prefix=

@end example

Where  is a unique location where the gdb

with SIS will be created.

@subheading Make the Debugger

From tools/build-sis execute the following command sequence:

@example

make all install

@end example

NOTE: The @code{make} utility used should be GNU make.

@section GDB with PowerPC Instruction Simulator

@subheading Make the Build Directory

Create a build directory for the SIS Debugger

@example

cd tools

mkdir build-ppc

@end example

@subheading Configure for the Build

Configure the GNU Debugger for the PowerPC

Instruction Simulator (PSIM):

@example

cd tools/build-ppc

../@value{GDB-UNTAR}/configure \

      --target=powerpc-unknown-eabi \

      --program-prefix=powerpc-rtems- \

      --enable-sim-powerpc \

      --enable-sim-timebase \

      --enable-sim-inline \

      --enable-sim-hardware \

      --enable-targets=all \

      --prefix=

@end example

Where  is a unique location where the gdb

with PSIM will be created.

@subheading Make the Debugger

From tools/build-ppc execute the following command sequence:

@example

make all install

@end example

NOTE: The @code{make} utility used should be GNU make.

@section GDB for DINK32

@subheading Make the Build Directory

Create a build directory for the DINK32 Debugger

@example

cd tools

mkdir build-dink32

@end example

@subheading Configure for the Build

Configure the GNU Debugger to communicate with

the DINK32 ROM monitor:

@example

cd tools/build-dink32

../@value{GDB-UNTAR}/configure --target-powerpc-elf \

    --program-prefix=powerpc-rtems- \

    --enable-targets=all \

    --prefix=

@end example

Where  is a unique location where the

gdb Dink32 will be created.

@subheading Make the Debugger

From tools/build-dink32 execute the following command sequence:

@example

make all install

@end example

NOTE: The @code{make} utility used should be GNU make.
