Looking for a C++ compiler

[davideotape]

Hi, I am just starting to learn c++, but the book I am learning from only suggests windows compilers. The compiler needs to be able to compile .cpp files so they can be run under ubuntu 8.10.

All help appreciated :D

Ubuntu has a C++ compiler built in by default.

Assuming you have a file called main.cpp use this command line:

g++ main.cpp -Wall -o main

Hope it helps you!

To add to that, it may help to know what's going on with this command.

g++: the program name.
main.cpp: your file you are trying to compile
-Wall: a "flag" (an indicator) to G++ to print all warnings.
-o: a flag that says, "make the executable to the name provided."
main: the generated executable.

To run your newly-created executable, simply run the command line:

./main

Assuming you used cout or printf, it'll print in the terminal your output.

Not sure if it is in there by default you might need to install build-essential.

Thanks a lot guys, that works a treat :)

David,

Just remember if you book is making MS Windows API calls they will not compile on the Ubuntu System. Start of by making only POSIX (http://en.wikipedia.org/wiki/POSIX) compliant and Standard C++ (http://www.cplusplus.com/reference/) function calls. This will get you the basics of what you need to accomplish.

Other Libraries of note which I use:
Poco (http://pocoproject.org/)
Boost (http://www.boost.org/)
glib (http://library.gnome.org/devel/glib/2.18/)

Ubuntu Windowing API's which I use:
wxWidgets (http://www.wxwidgets.org/)

For C++ programming, I personally recommend, "The C++ Programming Language" (http://www.research.att.com/~bs/3rd.html) by Bjarne Strousstrupp

For wxWidgets programming, I personally recommend, "Cross-Platform GUI Programming with wxWidgets" (http://www.wxwidgets.org/docs/book/) by Smart and Hock.

Libraries like poco, boost and glib, posix and std::C++ can be cross compiled to different hardware architectures very easily... i.e. X86 to ARM-9 for example. And I don't need to change my code to make them work on the different architecture. [there are some caveats of course... ]

Hope this helps!
