How to compile in Linux for Windows
Hi! :) I just moved on linux few days ago and I want to compile something for Windows. I wrote the code in Code::Blocks thinking that it will compile it as an exe, it says it can't find conio.h windows.h etc... How can i solve this? I am thinking to open it with Wine, see if it works and then run it on a Windows PC. Thanks.
conio.h is not part of standard C++. You don't want to have it in your code.
Nevertheless, a compiler will by default compile binaries for the native platform. In order to compile for non-native platform, one must use a cross-compiler that has necessary libraries of the target platform. There should be (Windows) cross-compilers available for some Linux distributions. They might have "mingw" in their name.

get MinGW that is compiled for linux that target's win32 executables and use it
and get
http://sourceforge.net/projects/conio
then compile your project with it!

I tried to compile something using i686-w64-mingw32-g++ hello32.cpp -o hello32.exe
But when i run it on Win XP 32 bits i get the next error
This application has failed to start because libstdc++-6.dll was not found. Re-installing the application may fix this problem.

Try -static.
If that doesn't work, just go into your mingw32/bin folder and copy the dll's that the exe tells you into the folder with the exe.

It is not recommended to do optimizations during development, but when you do start caring about performance you can use optimization flags.
The speed performance flags are:
-O is the lowest optimization,
-O1 is more optimized than -O
-O2 is more optimized than -O1
-O3 is the highest optimization
And there are other optimization flags:
-s strip all binary symbols for size
-Os optimize for size
If you want a slightly faster compile you could put all the dll's with the exe, but it really isn't anything.
