Hi Adam,
I tried to compile the c++ program using stl map class with only uclibc++ libraries outside the l4env and got the same compilation error. I have posted the compilation error both from l4env and non l4env below.
=================================================================================================================================
1) Compilation error from non l4env compilation (i.e just compiling on a linux box with uclibc++ libraries only and excluding the standard c++ libraries)

2) Compilation error from l4env compilation (i.e normal compilation during the creation of l4 packge in tudos/l4/pkg). I have shown only the compilation error from the long log file.

=================================================================================================================================
From the logs I think the error is due to uclibc++ library than l4Env. It would be great it if you could give me some pointers on what is going wrong there. The source file is the same mymap.cc file discussed in the previous posts.
Thanks for your time,
karthik
