It's fantastic that you continue working on this project Brunni.
Keep up the good work !

edit: I just tested 2.0 alpha
- the install .bat files don't work, you have to copy includes and libs manually, in pspsdk and visual studio for the PC version
- filenames are now case sensitive when you load a file with an OSLib function, I took 1 hour to understand why my 1.0 code wouldn't work ;)

Thanks for your support and your bug reports ^^

I'm confused when you are saying that oslLoadImageFile is now case sensitive... there is no reason at all.
I'm using sceIoOpen and so on. Maybe fopen (like I was using before) wasn't? But fopen was a wrapper to sceIo anyway. That's something to investigate ^^
At least putting './directory' won't work because of a bug that I will correct (I take the first '.' to detect the extension instead of the last one). You don't need putting a . before the path anyway.

nDEV> What are the errors?

goebish> Which files are missing?

I think you are mixing java objects and C structures (which are completely different)...
OSLib is C only, so setting a pointer to NULL won't free the associated memory (of course), it will just... set this pointer to NULL (which is usually a bad idea if your object hasn't been freed first because you'll loose any reference to that object, making a memory leak).
You HAVE to do oslDeleteImage, and maybe later set the pointer to null. If you want a clean way to eventually delete objects that may not have been loaded, you could do something like this:

I'm thinking about automatically swizzling images upon loading but I need your advice. You'll have to specify OSL_UNSWIZZLED to make sure it isn't swizzled, else it will be. Does this seem better to you?
Thanks in advance for your opinion

That sounds good to me! What would be the disadvantages?

You can't modify swizzled images ;)

Oh, you can absolutely modify swizzled images... It's just a tiny bit trickier :)

Oh thank you. Now oslGet/SetImagePixel take swizzling in account. This is just a problem for people who are using the old method (raw access to image->data) but they will be warned (in the breaking changes section): if they want their old code to work, just put an oslSetImageAutoSwizzle(0) in the beginning of the code. For new projects, you can just specify the OSL_UNSWIZZLED flag at image loading.
I think this behaviour is ok. Many thanks for your advice ^^

How to use oslib2 pc version with "emu.h"?

Brunni · Joined: 08 Oct 2005 Posts: 186

Hmm it's like the first version (OSLib 1.0). What is the problem?
No I'm not pspdonkey. Other people can use the logo if they want because the source is available on my site ;)

LOREK> Ok, now I can answer you precisely ^^
I'm sorry, I'll have to do something more about this PC version, I haven't tested it at all since the 2.0 release (I always use PSPLink, it's a bit more handy). I'll try to fix it and improve a bit for the next release. For now, here is what you can do if you want to begin from zero (you can also use the OSLib pack from Yodajr, which includes cygwin, pspsdk, OSLib, tools and everything you need; but it's always good to know how to do):
- Install Visual C++ Express 2008.
- Modify the Install.bat in the PC directory of the OSLib zip to make it point to C:\Program Files\Microsoft Visual Studio 9.0 instead of 8. Also, the script is missing to copy some files, so modify the lines that copy individual .h files with:
copy *.h "%VCDIR%\include\oslib"
- Execute that Install.bat.
- Create a new, empty Win32 project.
- Add a main.cpp file,
- Paste your sample code in it.
- Right click on your project (just below the solution, containing 1 project),
- Select Properties,
- In the left treeview, select Linker, Input. In the additional dependencies rightwards, add oslib.lib libpng.lib libz.lib opengl32.lib glu32.lib
- Compile with F7, it will probably give an error that "GL/GlExt.h" not found, double click on that error, it will bring you to the line #include "GL/glext.h", which you can comment out.
- Press Ctrl+F5 to compile and launch it directly.
Tip: For a better compilation time, you may try to put the following libraries in the linker, input, additional dependencies section: advapi32.lib gdi32.lib user32.lib oslib.lib opengl32.lib glu32.lib libcmt.lib libpng.lib libz.lib and set Yes (/NODEFAULTLIB) in the Ignore All Default Libraries section.
Hope it helps,
Brunni

Btw I'm sorry if this topic seems dead, I'm still developping this library actively but most people ask their questions on playeradvance and not here.

Has anyone found bugs, ideas or something that can help me for further development? :)

Thank too answer Brunni! I needed this solution when I bricked my PSP because I couldn't test my games. Currently my PSP is OK and I can continue work over game already.
OSLib is the best for creation 2D games like GBA games! I wish you success in farthest deployment this library! I write on your library shooter game like Contra(NES).

PS.
I use devkitPSP from DevKitPro + Dev-Cpp + MinGw on the Win32 platform.
In the nearest future I will upload alpha demo to this topic.

Hi! :)

Sorry to bother, but: is it possible to have the source code of OSLib version 2.10?
It seems only 1.0 source code has been released...why?

Many thanks
Ciaooo
