Compiling the Source

[stryke3]

I'm interested in playing around with the source and compiling it to see if I can't learn a bit about how emulators work. I've never worked on an emulator before, so I'm not sure exactly how to go about it. I downloaded the source to SNES9x, and it looks like I'd need about half a dozen different graphics/audio dev. packages to compile it.

I'm curious to know what yoyofr and the wonderful people behind TYL use to develop the emulator. Which IDE, compiler, dev tools, etc? I'm currently running Win XP, but I'll be switching over to Linux/BSD in the next month, so tools for either platform is fine for me.

SNES is not something to start learning on. Chip 8 is a good CPU to start with.

Thanks for the advice. I've been working on a Virtual Machine for the last 2 years, actually. Part of a research project, but I was curious to look at how something was emulated. I'll take a look into the Chip 8 emulator. Thanks.

I've personnaly started emulation with nes.
I think the nes module of ljp (and ljgp32) should probably have still some code from it (about 6years ago... :-) ).

dang it man.

after downloading the source from you i just had to download VIM(need my markup)

sigh.

as for the OP what software tools do you use?

[yoyofr]

OP ? what's this ?

[predanuke]

ohh sorry, different message boards different acronyms

OP = original poster ;D


so what do you use to edit the C++ files, compile them, etc?

[laxer3a]

Cygwin under XP, a text editor, makefile... standard stuff

[yoyofr]

ultraedit is nice as a text editor for C/C++/HTML/...

[stryke3]

I've been using Bloodshed's Dev-C++ with the cygwin port of the g++ compiler.

i just tried to compile the 0.1 source, but i don't have the included "jpeglib.h".
which one are you using, or where can i get this one?

[laxer3a]

Hi,

Get it from the pspsdk from ps2dev...
Actually every include that are not in the source package of TYL are from the PSPSDK.

So if you look well, in their SVN they have it.

[obake]

okay, i guess i got the missing files now.
i am using devkitPRO r15 with devkitPSP r4

but i still cant make the project, i get an error:
c:\devkitpro\devkitpsp\bin\..\lib\gcc\psp\4.0.1\..\..\..\..\psp\bin\ld.exe: cannot find -ljpeg

what exactly is that -ljpeg?

it's from the makefile:
#USE_PSPSDK_LIBC=1
LIBS = -lm -lpspaudio -lpspgu -lpsppower -ljpeg

but i don't know, how to solve this prob...

[smiths]

gotta get libjpeg from the svn repository

svn co svn://svn.pspdev.org/psp/trunk/jpeg I believe

[obake]

what is that svn actually?

i find it very confusing. do you have to copy and paste all of the entries and save them manually? or is there a possibility of downloading the files somewhere?

[laxer3a]

SVN is a tool like CVS : archiving, source file management system.

In my case and yoyo case, we download the whole SVN tree and recompile the whole tool suite each time.
(takes roughly 3 hours of compile...)

(actually the v0.1 source may be broken with the latest version of the SVN then)

you would better go to :
www.ps2dev.org

Get the whole stuff of the SVN over there, READ THE FORUM before asking... All the info you need is there if you look... Time and patience are the key !!!

I dont think it is our role to support the PSPSDK here.
Once you have a problem after you got the PSPSDK working, we can help you.
