Hi Roberto,
Great that you are looking at this, I am afraid I don’t know any of the
specifics of compilation under windows. Sam Gillingham did the work on the
spdio library so the viewer could be built. However, we have been discussing
how useful it would be to get the python binding available for windows so I’m
very happy to help you in what ever way I can.
For the error you’ve put in the email could you wrap the outDir.native() into a
std::string:
std::string outMess = std::string("Directory \'") +
std::string(outDir.native()) + std::string("\' was not present. Did you build
the directory structure?”);
It compiled OK on my mac.
Cheers, Pete
