To reproduce, on a fresh install: $ cat test.cpp #include <vector> int main() { std::vector<int> v; v.push_back(1); return 0; } $ g++ test.cpp -g $ gdb a.out -ex start Reading symbols from a.out...done. Temporary breakpoint 1 at 0x400956: file test.cpp, line 3. Starting program: /home/emaisin/a.out Traceback (most recent call last): File "/usr/lib/debug/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.19-gdb.py", line 63, in <module> from libstdcxx.v6.printers import register_libstdcxx_printers ImportError: No module named 'libstdcxx' Temporary breakpoint 1, main () at test.cpp:3 3 std::vector<int> v; (gdb) It seems like the fixup for multiarch actually adds an extra "..": if not os.path.basename(os.path.dirname(__file__)).startswith('lib'): backdirs += 1 # multiarch subdir Removing these two lines almost makes it work: $ gdb a.out -ex start Reading symbols from a.out...done. Temporary breakpoint 1 at 0x400956: file test.cpp, line 3. Starting program: /home/emaisin/a.out Traceback (most recent call last): File "/usr/lib/debug/usr/lib/x86_64-linux-gnu/libstdc++.so.6.0.19-gdb.py", line 63, in <module> from libstdcxx.v6.printers import register_libstdcxx_printers File "/usr/lib/x86_64-linux-gnu/../../share/gcc-4.8/python/libstdcxx/v6/printers.py", line 54 raise ValueError, "Cannot find type %s::%s" % (str(orig), name) ^ SyntaxError: invalid syntax Temporary breakpoint 1, main () at test.cpp:3 3 std::vector<int> v; That last problem is tracked in bug #1256419, which is still a pending issue in Trusty.
