[Nix-dev] TeamViewer process ends with "undefined symbol: _ZN10__cxxabiv120__unexpected_handlerE"

[Christoph-Simon Senjak]

Hi.

On my installation, the teamviewer GUI will start, but when trying to 
connect to a remote host, the main window of the GUI minimizes, but 
otherwise, nothing will happen, no error message, it is as if the 
connection was successfull, but it never starts.

I have found one possible cause of this being the fact that a subprocess 
which TeamViewer tries to call (and successfully calls on a Debian 
Machine where I tested it) is in the directory share/teamviewer/tv_bin 
and called TVGuiDelegate. When I try to run it, it doesn't even get to 
the main method, but just outputs

./TVGuiDelegate: symbol lookup error: ./TVGuiDelegate: undefined symbol: 
_ZN10__cxxabiv120__unexpected_handlerE

and in fact, no library in the rpath contains this symbol. On my Debian 
machine, it uses this function from a subdirectory "RTlib", which 
apparently is there to make it more system independent. However, in the 
nix package

https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/networking/remote/teamviewer/default.nix

on line 39, this directory is deleted, probably because these libraries 
should be provided from other nix packages. But the ones from nix do not 
expose the symbol _ZN10__cxxabiv120__unexpected_handlerE, according to 
readelf, while the ones in RTlib do.

Maybe it would be a good idea to add an option to the packge to use its 
own library rather than system packages.

Any help on this issue would be appreciated, especially by the maintainers.
