g++5 ABI test tool
|
|
||||||
==================
|
|
||||||
|
|
||||||
This is a simple tool to test a system for g++5's libstdc++ at runtime.
|
|
||||||
|
|
||||||
GCC5.1 introduced a new library ABI for the C++ standard library.
|
|
||||||
The old 3.4 .. 5.0 ABI is not compatible.
|
|
||||||
|
|
||||||
Some GNU/Linux distributions systems switched to the new ABI already
|
|
||||||
and compile plugins with the new gcc.
|
|
||||||
|
|
||||||
If a plugin uses a c++ library that is also shipped with ardour-bundles,
|
|
||||||
the ABI of that library must match. Currently known cases: gtkmm, glibmm.
|
|
||||||
|
|
||||||
e.g. Ingen or eq10q provided by a distro compiled with gcc5 will not
|
|
||||||
load in Ardour as provided by ardour.org compiled with gcc4 because ardour
|
|
||||||
ships an incompatible gtkmm, glibmm, cairomm, ...
|
|
||||||
|
|
||||||
The plugin will fail to load. For example:
|
|
||||||
|
|
||||||
```
|
|
||||||
suil error: Unable to open UI library /usr/lib/lv2/sapistaEQv2.lv2/gui/eq10qs_gui.so (/usr/lib/lv2/sapistaEQv2.lv2/gui/eq10qs_gui.so: undefined symbol: _ZN4Glib7ustringC1ERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE)

||||||

|
|
||||||
```
|
|
||||||
|
|
||||||
ie `Glib::ustring::ustring(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)`
|
|
||||||
|
|
||||||
|
|
||||||
Compilation
|
|
||||||
-----------
|
|
||||||
|
|
||||||
This tool must be compiled on a system with gcc5.1 or later.
|
|
||||||
|
|
||||||
make
|
|
||||||
|
|
||||||
will fail the resulting binary does not use the new __cxx11 ABI.
|
|
||||||
The resulting binary will *not* run on systems with only the old ABI.
|
|
||||||
|
|
||||||
For convenience (packaging gcc4 builds), pre-compiled binaries are included.
|
|
||||||
|
|
||||||
|
|
||||||
Check
|
|
||||||
-----
|
|
||||||
|
|
||||||
The idea is to include the precompiled binaries in the installer
|
|
||||||
|
|
||||||
- Ardour/gcc-4 installer must fail if the binary runs
|
|
||||||
- Ardour/gcc-5 installer must fail if the binary does not run
