Re: [cpp-netlib-devel] cpp-netlib async server request - bad cast exception thrown

[Max M. <ma...@kt...>]

Hi!

I have now done a few tests regarding the ASyncProxy class I mailed about.

The original problem arised when compiling with MSVS 2010, using boost 1.44 installed with the boost pro installer package. This yielded a bad_cast exception thrown whenever a request was made.

Then I decided to test it on my Ubuntu machine. I installed boost 1.45 using bjam. Everything worked fine. I got no exception and the connection.write("hello") indeed sent that very response to my browser. I concluded that I should probably build boost 1.45 on my windows machine, which is what I did today. Following your advice I also checked out cpp-netlib from the master branch of the git repository, and used that instead of the download.

Originally I got a compile error, but once I included boost/or.hpp in the boost/network/version.hpp file it compiled. However, it still does not work on my windows distribution, while it does on my ubuntu distribution. I still get a bad_cast exception thrown.

Do you have any idea what might be the problem? Any known compiler weirdness regarding MSVC 2010 vs g++? I am using firefox both on windows and on my ubuntu machine, they both issued GET requests, difference was the user-agent header.

Thanks for any and all replies.

Best regards,
Max Malmgren

Dean has already spotted the problem in ASyncProxy::operator().
Apart of that please consider using master or 0.8-devel branch of
git://github.com/mikhailberis/cpp-netlib.git until 0.8.1 is released:
there are important fixes to async_connection.
