sstream errors

I have a project that compiles and builds on VS2005 with two different SDKs(one for Windows CE5 and one for Windows CE6), was converted into VS2008 project, compiles and builds on these SDKs as well using Win EC7
Now, I want to compile the project using the Toradex Apalis SDK, and I end up with sstream errors.
I have added #include to my file, and can not get past 132 errors and 17 warnings.
Any suggestions on how to resolve?
Thank you.

Can you please post the build log, so we could understand those errors?
