Question

How to use valgrind in xterm with gdb on Linux (redhat) ?

The command open a xterm terminal, which disappears immediately.

xterm -e gdb valgrind --tool=drd --read-var-info=yes ./star &

I need it to do debugging for C++ code.

Thanks

Answer 1

If you really want to debug valgrind , the procedure is:

1. Run xterm -e gdb valgrind &
2. In the xterm , set up your breakpoints and such
3. Start the program with run --tool=drd --read-var-info=yes ./star

Answer 2

This should work:

xterm -e gdb --args valgrind --tool=drd --read-var-info=yes ./star &

assuming you want to debug valgrind itself (which seems unlikely, given the question).

If what you really want to do is debug ./star , while it is running under DRD , that used to be pretty much impossible, but became possible with recent valgrind versions, which have embedded gdbserver.

To do that, you'll want two xterms:

xterm -e valgrind --tool=drd --read-var-info=yes --vgdb-error=1 ./star &
xterm -e gdb -ex 'file ./star' -ex 'target remote | /path/to/vgdb' &
