You need to build Cross-GDB to debug remotely by running a gdb server on the Raspberry Pi device and controlling debug session using Eclipse on Windows.

 

1. Prepare to build GDB

Assign the following contents to the C:\MinGW\msys\1.0\opt\crosstool\src\build_cross_toolchain.sh:

#!/bin/bash
export PATH=.:/usr/local/bin:/mingw/bin:/bin
export PATH=$PATH:/c/WINDOWS/system32:/c/WINDOWS
export PATH=$PATH:/c/WINDOWS/System32/Wbem
export TARGET=arm-linux-gnueabihf
export PREFIX=/opt/crosstool/gcc-8.3.0-glibc-2.28/$TARGET

cd /opt/crosstool/src/build-gdb
find . -delete
cp -R ../gdb-8.2.1/. .
LDFLAGS="-Wl,-s -Wl,-static -static -static-libgcc" \
  ./configure --prefix=$PREFIX --target=$TARGET \
    --with-expat --with-libexpat-prefix=/usr/local
if [ "$?" -ne "0" ]; then
    echo "=== build script: failed to configure cross-gdb-client ==="
    exit 1
fi
make
if [ "$?" -ne "0" ]; then
    echo "=== build script: failed to make cross-gdb-client ==="
    exit 1
fi
make install
if [ "$?" -ne "0" ]; then
    echo "=== build script: failed to install cross-gdb-client ==="
    exit 1
fi

cd /opt/crosstool/src/build-gdb
find . -delete
cp -R ../gdb-8.2.1/. .
cd gdb/gdbserver
export CC=$PREFIX/bin/$TARGET-gcc
export CXX=$PREFIX/bin/$TARGET-g++
export AR=$PREFIX/bin/$TARGET-ar
export RANLIB=$PREFIX/bin/$TARGET-ranlib
./configure --host=$TARGET --target=$TARGET
if [ "$?" -ne "0" ]; then
    echo "=== build script: failed to configure cross-gdb-server ==="
    exit 1
fi
make
if [ "$?" -ne "0" ]; then
    echo "=== build script: failed to make cross-gdb-server ==="
    exit 1
fi
cp ./gdbserver $PREFIX/usr/bin
cp ./gdbreplay $PREFIX/usr/bin

echo "=== build script: OK ==="

 

2. Build GDB

• Run C:\MinGW\msys\1.0\opt\crosstool\src\build_cross_toolchain.cmd and wait until it completes.
• Replace TARGET=arm-linux-gnueabihf with TARGET=arm-linux-gnueabi in build_cross_toolchain.sh, then run & wait for build_cross_toolchain.cmd again.
• If there are no errors, shutdown the MinGW VM and make snapshot "SNAP-F".
