./configure --host=arm-linux-gnueabihf --with-sysroot=/path/to/sysroot make && make install DESTDIR=/path/to/sysroot Then execute Valgrind with the correct library path:
# Check Valgrind version and installation path which valgrind valgrind --version ls -l $(dirname $(which valgrind))/../libexec/valgrind/vgcore Test library dependencies of vgcore ldd $(dirname $(which valgrind))/../libexec/valgrind/vgcore how to fix unable to load vgcore error code 127
ulimit -c unlimited ./your_program gdb ./your_program core Scenario : Embedded Linux developer using a custom toolchain (glibc 2.28) on a host with glibc 2.31. Running Valgrind produces: disable vgcore generation:
cd /tmp cp $(dirname $(which valgrind))/../libexec/valgrind/vgcore vgcore.orig sudo gcc -static -o /usr/local/libexec/valgrind/vgcore /usr/src/valgrind/coregrind/vgcore.c Note : Requires Valgrind source tree. This forces a statically linked vgcore , eliminating library dependencies entirely. If the error persists and core dumps are not essential, disable vgcore generation: how to fix unable to load vgcore error code 127
