<DIV></DIV>Hi All, 
<DIV></DIV>
<DIV></DIV>I have just downloaded and installed MinGW 2.0 to upgrade my development 
<DIV></DIV>environment to the latest (easily available) GCC. The installation process 
<DIV></DIV>was surprisingly painless and getting it to work with Dev-Cpp was just as 
<DIV></DIV>easy. Good stuff so far. But... 
<DIV></DIV>
<DIV></DIV>I just wrote a command line program that does a little string manipulation 
<DIV></DIV>and spits out (read as cout &lt;&lt; (std::string)) a modified string (using the 
<DIV></DIV>command line parameters as input). The complete source is less 100 lines of 
<DIV></DIV>code and resides in a single file. I make use of the <IOSTREAM>and <STRING>
<DIV></DIV>headers. I compiled and found it worked perfectly, but the executable was 
<DIV></DIV>468KB in size! I was expecting something more along the lines of 10KB. So I 
<DIV></DIV>tried the following little program: 
<DIV></DIV>
<DIV></DIV>#include <IOSTREAM>
<DIV></DIV>#include <STRING>
<DIV></DIV>
<DIV></DIV>int main(int argc, char *argv[]) 
<DIV></DIV>{ 
<DIV></DIV>std::string s = "Hello, World"; 
<DIV></DIV>std::cout &lt;&lt; s; 
<DIV></DIV>return 0; 
<DIV></DIV>} 
<DIV></DIV>
<DIV></DIV>This simple "Hello, World" demo compiles to 442KB (using default compiler 
<DIV></DIV>settings, no optimization, no exception handling - and 156KB using the old 
<DIV></DIV>Dev-Cpp default compiler). This is a little extreme, don't you think? 
<DIV></DIV>
<DIV></DIV>So does anyone know of a way to reduce the file sizes generated by GCC 3.2? 
<DIV></DIV>The only thing that springs to mind is that the template class handling of 
<DIV></DIV>GCC is not that great. If we try the same demo using C-code (compiled as 
<DIV></DIV>C++): 
<DIV></DIV>
<DIV></DIV>#include <STDIO.H>
<DIV></DIV>
<DIV></DIV>int main(int argc, char *argv[]) 
<DIV></DIV>{ 
<DIV></DIV>char* s = "Hello, World"; 
<DIV></DIV>printf("%s", s); 
<DIV></DIV>return 0; 
<DIV></DIV>} 
<DIV></DIV>
<DIV></DIV>we get a program that compiles to 21KB (and 9KB using the old Default 
<DIV></DIV>Dev-Cpp compiler - even this shows a large increase in size using GCC 3.2)! 
<DIV></DIV>
<DIV></DIV>Regards, 
<DIV></DIV>Marc.
