Try changing the "a smallgame" folder to "a_smallgame".

Just tried, and no go.

"command not found"

You're using a Mac? Macs have the which command. WTF. Are you sure you spelled it right?

Yep, even tried again by copying n pasting what you wrote. Maybe because I have PPC version, not intel?

Um, try typing

man which

to see if that gives you a manual entry






My manwich!

man which DESCRIPTION which takes a list of names and looks for the files which would be exe- cuted had these names been given as commands. Each argument is expanded if it is aliased, and searched for along the user's path. Both aliases and path are taken from the user's .cshrc file. FILES ~/.cshrc source of aliases and path values DIAGNOSTICS A diagnostic is given for names which are aliased to more than a single word, or if an executable file with the argument name was not found in the path. BUGS Must be executed by a csh(1), or some other shell which knows about aliases. HISTORY The which command appeared in 3.0BSD. 3rd Berkeley Distribution April 23, 1991 3rd Berkeley Distribution

Okay, I'm officially confused.

what is the output of

echo $path

Also, I see that I've been sigged again.

...you know I was referencing Futurama there, right?

path /bin /sbin /usr/bin /usr/sbin

and yea, I did. I couldn't stop laughing though :ROFL:

I'm very lost.

Where is the cc1plus that you found located?

I've been considering releasing an updated version of Slash-N-Flash to be compatible with newer firmwares.

The flashing works, but once it hits a folder that's hidden, ERROR :/
I was just wondering what I should do about the hidden folders(or maybe read only?) problem that sony has done to the recent firmwares? Is there some way to disable that through a program?
I've tried disabling it through windows, but it doesn't work.

What should I do? Is it even possible to fix?

I will have to check later, but, I am pretty sure that it was in the original gcc 3-3 folder. I will be back on in about 3 hours to double check that though. Very interesting how complicated this is getting for me... :down:

Since it seems like my computer can not compile at all, would it really be a request if I asked in the open forums for people to help me to compile?

I guess it probably would, but I was just curious if that would work.

Does compiling, and creating the actual compiler, usually take this long? Because doing it on a Mac is very time consuming, its like constant hitting and missing the mark.

Sorry to interupt your problem spike...

Is there anyway I can find UIDs from things in modules not by me? Finding a threads UID in a Sony module for example, I do want to be able to find all UIDs, so files, threads, heaps, pretty much everything if possible.

Also, is there a program out there that handles formatting of C functions without having the compiler? I'm looking for something IDE wise, without the integrated bits (DE?), just to highlight things such as comments, data types, etc, so I can carry it around when I go to college? Dev-C++ was what I was using, but it seems to take too much resources for some of the computers :down:

Thanks.

I've still not had any problems with hidden folders.

The only problems I had was for files which I managed to sort out by using sceIoChstat.

hey i have a quick question, is there a way to get a string from a file off the internet, like i want to get a line from blackbelttcon.com/test.txt. is that possible. if not what should i use to do that. thanks

Use sockets/libhttp/libcurl to GET it.

LTE's (irrlicht 1.0 for psp really) 12th example download's an image off their site and displays it. Looking at the code it's very simple (well, depends who reads the code i guess) and I recommend it if you intend to use Irrlicht for rendering.

I used to use Dev C++ too, then I discovered Notepad++. Way better in my opinion. Has all the features of Dev C++ (minus the compiler) plus more. My favorite is the macro function, for those tasks that have to be repeated over and over again. Also, uses only about 10 MB of ram, and very little hard drive space. I have it installed on my jump drive.

alright ill try the sockets, and i have LTE installed, the tutorials they have are having problems compiling, there are diff errors and stuff.

thanks guyx

I have tried installing the toolchain again on my computer via http://forums.ps2dev.org/viewtopic.php?t=5391

But this error keeps showing up for the last bit,

5. Checkout the psptoolchain script from subversion, and run it.
Open a terminal and type:

Code:

svn co svn://svn.ps2dev.org/psp/trunk/psptoolchain
cd psptoolchain
sh ./toolchain.sh

---

code ERROR: Set $PSPDEV before continuing. ../depends/check-pspdev.sh: Failed.

Just in case you didn't know, you don't need to type 'cd ~', just typing 'cd' without the ~ will take you to the same place.

hey im having a hard time understanding the code from the LTE and from the GET tutorials, can you give me like a sample code or something, i want to get a string from the file test.txt located under blackbelttcon.com

What has too many arguments now?

Are you back in the folder psptoolchain before running sh ./toolchain.sh?

Also, seeing as you're on a Mac and not Cygwin, you should type this instead:

sudo ./toolchain-sudo.sh

I don't know if toolchain-sudo.sh calls sudo itself...all I know is that it works, so I'm happy.

So far it says:

code sudo ./toolchain-sudo.sh --18:07:17-- ftp://ftp.gnu.org/pub/gnu/binutils/b...2.16.1.tar.bz2 => `binutils-2.16.1.tar.bz2' Resolving ftp.gnu.org... done.

Logged in! ==> SYST ... done. ==> PWD ... done. ==> TYPE I ... done. ==> CWD /pub/gnu/binutils ... done. ==> PORT ... done. ==> RETR binutils-2.16.1.tar.bz2 ...

Now it says:

You must Set $PSPDEV before running the toolchain script.

First type...

Code:

---

nano .bash_profile

---

Paste this into .bash_profile:

Code:

---

export PSPDEV=/usr/local/pspdev
export PATH=$PATH:$PSPDEV/bin

---

Press [CTRL] + [X], then type [y], then hit enter,

Then type...

Code:

---

source .bash_profile

---

Then run the toolchain script.


-edit-
nevermind, lol

:Cry: doesn't work, I saw that off of google and tried, but nope.

Really?

Did you do it like this...

nano .bash_profile <--Correct way

or

$ nano .bash_profile <--Wrong way

Copy and pasting the '$' is a common mistake,

I need some more help. Im trying to make a program that will dump flash0, flash1. It has a menu, but some things dont work how they are supposed to.

When I select to dump flash0, or flash1, it dumps both, even though I only selected a specific one. When I scroll down using Dpad it goes past the "Exit". Exit dumps flash0 I think but Im not sure. Pressing D_Pad down 1 or 2 times after Exit and then pressing cross exits the game. Selecting "Exit" is meant to exit the game.

I hope that made sense.

Here is my main.c:

Well guys, thanks for the help with my computer, but I think that it's time to move this conversation to another thread, probably this one. That way I don't get in trouble for getting off topic. But I will be back if more errors occur when I can finally compile ;)
