Hi all,
first of all, sorry if I am posting to the wrong category. My problem is: I used to be able to debug my C++ programs using gdb pretty printing. If I had a program like:
#include <vector>
int main() {
std::vector<int> V;
V.push_back(2);
V.push_back(3);
return 0;
}
And used gdb, at the "return 0;" line if I do "p V" I would receive something like (I don't remember the exact format):
$1 = {2,3}: size = 2, capacity = 5
I haven't used it for a while, and today I tried again and got:
$1 = {<std::_Vector_base<int, std::allocator<int> >> = {
_M_impl = {<std::allocator<int>> = {<__gnu_cxx::new_allocator<int>> = {<No data fields>}, <No data fields>},
_M_start = 0x603030, _M_finish = 0x603038, _M_end_of_storage = 0x603038}}, <No data fields>}
Which is the internal representation of the vector. While I do know how to read this, and how to obtain the actual values, I would like to know how to revert to the pretty-printing state.
I am using gcc version 4.8.2 and gdb version 7.7 on a x86_64 installation.
Thanks in advance for your help!

Try to downgrade GDB.

I fixed this problem by installing gdb-c++-pretty-svn from AUR.
As I think this shouldn't be on AUR, but in the main repository (it is pretty stable), of course I can test for you, which version do you want me to downgrade to?

If reinstalling of gdb-c++-pretty-svn solves your issue, then there is no need to downgrade GDB.

m0rph, it's not "reinstalling gdb-c++-pretty-svn". I didn't have it installed in the first place!
The pretty printers are part of the gdb package, so technically you shouldn't need to install gdb-c++-pretty-svn from AUR. Just having gdb used to be enough, and suddenly it is not anymore. This solution worked for me, but I don't think it is the desired solution.
For completeness:
daniel@dfleischman ~ $ pacman -Ql gdb | grep pretty
