Codelite g++ 64 bit compile

[lucasart]

hello

i'm writing C++ code using codelite and g++ (installed CodeLite from the Ubuntu 10.10 repositries).

how do i compile the program for amd64 ?#

i tried to add -m64 to g++ -c command but it doesn't seem to work as sizeof(int) still equals 4.

thank you

Not sure how from that ide but you can compile using the terminal and g++.


in the terminal



g++ thenameofyourprogram.cpp



If you're running on a 64 bit machine, it will be compiled as such. If I'm not mistaken... I'm relatively new to the game.

On amd64, sizeof(int) is 4.

On amd64, sizeof(int) is 4.

thanks, i naively assumed it would be 8.

sizeof(long) is probably 8, though.

Indeed it is. So is type long long.
