cannot find string element /int8_t in registry

[AlexanderFabisch]

I am trying to load a logfile with pocolog_cpp. I get the following exception:

terminate called after throwing an instance of 'std::runtime_error'
  what():  cannot find string element /int8_t in registry

This is the backtrace:

Does anybody have an idea? The logfile can be loaded in rock-replay and I could not find any port that uses int8_t.

@hemker

Maybe you could have an idea? Do I have to load an additional typekit? How can I do that?

[hemker]

Hey,
could you please provide me your source code? I think it has something to do with missing typekits. If you want to, take a look into https://github.com/rock-cpp/rock_replay/blob/master/src/ReplayHandler.cpp especially method loadStreams (directly at the beginning). There is some general typekit (not on demand) loading stuff.

This line here is crashing: https://git.hb.dfki.de/InFuse/pocolog2msgpack/blob/master/src/Converter.cpp#L35

I am trying to add

orocos_cpp::PluginHelper::loadTypekitAndTransports("orocos");

I hope that is all. tools/orocos_cpp seems to have a lot of dependencies... I pushed it to another branch: https://git.hb.dfki.de/InFuse/pocolog2msgpack/tree/orocos_cpp . I still have the problem with the logfile that I am working on.

Maybe the logfile is just broken. Loading a specific stream with pocolog (ruby) crashes with another error:

Okay, could you provide the logfile via Fileserver/Temp please?
