[Bug 1135254] New: libstdc++-v3's STL prettyprinters are not used by gdb
http://bugzilla.suse.com/show_bug.cgi?id=1135254 Bug ID: 1135254 Summary: libstdc++-v3's STL prettyprinters are not used by gdb Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Development Assignee: bnc-team-screening@forge.provo.novell.com Reporter: tdevries@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- So, by default we get: ... (gdb) p freqs $2 = {_M_t = { _M_impl = {<std::allocator<std::_Rb_tree_node<std::pair<char const, int> >
= {<__gnu_cxx::new_allocator<std::_Rb_tree_node<std::pair<char const, int> > = {<No data fields>}, <No data fields>}, <std::_Rb_tree_key_compare<std::less<char> >> = { _M_key_compare = {<std::binary_function<char, char, bool>> = {<No data fields>}, <No data fields>}}, <std::_Rb_tree_header> = {_M_header = {_M_color = std::_S_red, _M_parent = 0x0, _M_left = 0x7fffffffdb18, _M_right = 0x7fffffffdb18}, _M_node_count = 0}, <No data fields>}}} ... instead of: ... (gdb) p freqs $1 = std::map with 0 elements ...
Users can install this relatively easily (as described at https://sourceware.org/gdb/wiki/STLSupport), but it would be good to have a better out-of-the-box experience. Fedora does have this. -- You are receiving this mail because: You are on the CC list for the bug.

My reasoning was you'll unlikely be debugging a C++ program if you are not doing C++ development in which case you'd have libstdc++-devel installed. It's also possible to split out the python bindings into a separate package and having the supplements there (does lldb also use the same pretty-printers?). Note that libstdc++ is almost always installed on the system so you'd get the pretty-printers once you install gdb. Note there are different pretty-printers for each minor variant of libstdc++: libglib-2.0.so.0.4800.2-gdb.py libstdc++.so.6.0.22-gdb.py libgobject-2.0.so.0.4800.2-gdb.py libstdc++.so.6.0.24-gdb.py libstdc++.so.6.0.19-gdb.py libstdc++.so.6.0.25-gdb.py libstdc++.so.6.0.21-gdb.py but only _one_ shared library eventually prevails:
ls /usr/lib64/libstdc++.so.6* /usr/lib64/libstdc++.so.6 /usr/lib64/libstdc++.so.6.0.25
so splitting the pretty-printer apart and pulling it in via a supplements would eventually help that as well. Now I need to read up how Supplements work in face of package removal and how they relate to Recomments/Suggests. -- You are receiving this mail because: You are on the CC list for the bug.

So instead of adding an explicit Recommends into gdb, you add the Supplements to the pretty-printer aka, "If you can get this and also have foo, then you might want this too" It is only a soft dep, so can still be removed or skipped (default for small JeOS and container images). -- You are receiving this mail because: You are on the CC list for the bug.

When doing zypper in libstdc++6-gcc9 the pretty-printer package is not selected. Note that the Supplements above mentions the virtual package libstdc++6 the libstdc++6-gcc9 package provides (and the system currently has libstdc++6-gcc8 also providing it but in a non-matching version). So my conclusion is for the SLE12 Toolchain module this split is counter-productive since people will need to explicitely install libstdc++6-pp-gcc9 to debug C++. Michael - is the virtual package thing the issue here? If so it might in the end work (since the actual installed runtime _will_ have the bare libstdc++6 name on the Toolchain module, just installing an unsupported runtime would cause this issue). -- You are receiving this mail because: You are on the CC list for the bug.
