I have no idea whats going on. Haven't had a chance to play with any other compilers yet, dunno if its my computer, probably my code. I miss java :oops:
thanks

try g++

T-Dawg · 2005-09-13 00:48:01

sorry I should have been more clear...
g++ will compile c++ files while gcc is C.
when you do g++ nameoffile.cpp it spits out an a.out executable. If you want to change that you can do

g++ -o nameofoutputfile nameoffile.cpp

and the executable will be nameofoutputfile.

or you can just type make and it will use the correct gnu compiler for you

Doesn't that require writing a makefile??

Snowman · 2005-09-13 02:25:57

Another problem with your code is that you declare q as an integer:

int q;

but you give it a double value:

q = 1.0 * n / d;

ah crap, thats why it wasnt working. stupid me...

thanks for the help everyone, works now

awalk · 2005-09-13 11:27:53

Dusty: Yes, it requires a Makefile.

Euphoric Nightmare · 2005-09-13 14:04:01

Actually no, its not needed. you can just type make project2_1

I just tested it on a random c file:

[sgillespie@SG-Arch01 cApps]$ make strTest
cc     strTest.c   -o strTest

awalk · 2005-09-13 14:09:38

Well I'll be. I stand corrected

Dusty · 2005-09-13 14:23:55

wow, that's cool.

Who says you don't learn something new everyday?

I stole that idea from phrakture who responded with this a long time ago on a similar question.

I remember that too but I could never get it to work....didn't realize you had to leave off the extension.

Euphoric Nightmare · 2005-09-13 21:47:10

Yep, I figured that out earlier today.

It says that nothing can be done or something.

Yeah, it's cool... but be careful with it... you almost always want to compile with -Wall, but "make myprog" won't do that.... unless you do "make CFLAGS=-Wall myprog"
