Building Cross-GDB in the MinGW VM
You need to build Cross-GDB to debug remotely by running a gdb server on the Linux PC 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_gcc_cross.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=i586-linux-gnu
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
cp ./libinproctrace.so $PREFIX/usr/lib
echo "=== build script: OK ==="
2. Build GDB
- Run C:\MinGW\msys\1.0\opt\crosstool\src\build_gcc_cross.cmd and wait until it completes.
- Replace TARGET=i586-linux-gnu with TARGET=x86_64-linux-gnu in build_gcc_cross.sh, then run & wait for build_gcc_cross.cmd again.
- If there are no errors, shutdown the MinGW VM and make snapshot "SNAP-F".
