trying to solve the pytango FTBFS with gcc5

Show all headers | View raw

Hello, guyes,

I am working on this bug report[1], and I would like your opinion.
this package depends on the tango library which was rebuilt with gcc5 and updated for the libstdc++6 transition.

Now as you can see in the bug report, pytango FTBFS with a missing symbol.
and indeed the missing symbol correspond to a c++11 string.

I would like to understand why pytango expect old abi string instead of the new c++11 even if during the build -std=cxx01 is given to gcc.
For information the files are in fact c++ files.

I also tryed with c++11 and I got the same error.

So I do not understand what is going on.
Is there something special done by distutil when compiling an extension ?
is it a problem with gcc (the C compiler) which doesn not use correctly the -std:cxx flag when compiling c++ files ?

any help would be appreciate.

thanks

Frederic
