I have a problem with compilation of calculator on C++ language. I use
Linux (Slackware 11) and GCC 3.4.6.
I taken example from Info-Help, wrote makefile. All program files base
on Info-Help. The log of compilation is in log file. There is one same
error. I guess that template class messages from standard library c++
use parameter type which not support some operations. But sources of
program not use this class explicitly. I don't know, what i must do.
