Problem with 'Hello World'

[pacman2323]

Ok, I'm following this tutorial: http://www.psp-programming.com/tutorials/c/lesson02.htm

And I've gotten all the way to here-
"Now open up a CYGWIN Bash Shell and "cd" into your "projects/helloworld" directory. Type "make" and your shell should output some stuff to you. It will tell you if your source code had any errors that made it uncompilable. Generally, if it gives you a few warnings, it's not a big deal. Errors are what you want to watch out for, warnings are just possible points that could cause bugs. Note: if you have Firmware Version 1.50, you can automatically generate your two folders by typing "make kxploit" instead of "make.""

But when I do that I get this-
make: *** No rule to make target 'main.o', needed by 'hello.elf'. Stop.

What went wrong?

ask the one who wrote that tutorial and/or the makefile for that helloworld. he screwed it up :=)

[pacman2323]

What did he screw up?

[pacman2323]

Oops, I mispelled the filename. My bad. I noticed it made 'hello' and 'hello%' to put on the PSP, but it also made 'hello.elf', 'main.o' and 'PARAM.SFO'. What do I do with those?

Got a problem with Lesson 3 though:

here's my code-

Code: Select all

&#125;

printf&#40;"Counter Finished."&#41;;
printf&#40;"Final Count&#58; %i", counter&#41;;

And here's the error I'm getting-

The link at the top of the page where that tutorial was found leads to their own forums:

http://www.psp-programming.com/dev-forum/

Perhaps you'll find better support there?

[dot_blank]

all after this is outside main function so code is
incorrect

Code: Select all

return 0;
    }
while(1) {
         sceCtrlReadBufferPositive(&pad, 1); 

[pacman2323]

So how would I rewrite it?

what oopo said, those ppl should know a lot better, since they made that stuff :)
