$(PSPBIN) is not properly set.

[slasher101]

yea change it to the REAL path =P

Well, first of all thanks for all the aswers, but it still won't work. I now get the original errors that he (still) can't find "freetype/config/ftheader.h". As for the environment variables, if this is what you geht when you type "echo %PATH%" - the (right) bin path is there - twice!

Ok, here comes the cheap solution. Inside the includedirectory was a folder "freetype2", inside that a folder "freetype" with all the files in it. Copied "freetype" into the include directory, everything works. I could have tried that earlier -_-. Anyways, thanks for all the help.

do echo %PSPBIN% and see what it outputs

because.. ya know.. pspbin env variable is not the path variable..

[Lukeson]

It echos... wait for it... %PSPBIN% !

Where can I change that?

[_dysfunctional]

It's not a windows environment variable, you have to do it for cygwin.

Type (In a cygwin command prompt):

PSPBIN = /usr/local/pspdev/bin
or
PSPBIN = /usr/local/pspdev/psp/bin

Depending on the directory freetype-config is in.

Then try running it again.

could some1 please answer my question???

I'm having troubles with pgeFont. I use it with the graphics.c library from Psilocybeing that is included as a sample that comes with pgeFont.

When I print a font with pge to the screen and use blitAlphaImageToScreen from the library, the image is totally messed up. I can do that before I print the text of after that, the result is the same.

Does anyone have a clue?

I read the thread and you've been given plenty of help. Use sceDisplayGetFrameBuf to get the address to send to pspDebugScreenSetOffset. Theres not much more that we can say without giving you the code.

Is there any functions to open/read/modify an archive in the SDK? I need to use an archive (type not important) but I don't want to reinvent the wheel if theres a way already.

[slasher101]

Yea i know Aura but i still need help?
thanks to every1 =)

you can build libzip for zip files and there are loads of stuff for doing 'wad/pak' files etc.

Ok awesome, I'll check that out thanks.

any libs for unraring files?

~!SlasheR!~

[Auraomega]

Is there a way to list heap UIDs? I see functions for listing the UID of modules but I've not found anything for memory. Am I right in assuming the PSP_HEAP_SIZE_KB allocates a heap with a determinable UID also? Finally if I allocate a heap in a function using sceKernelCreateHeap does that remove the need for the PSP_HEAP_SIZE_KB macro and no extra additions, or would I then have to allocate from the heap each time using sceKernelAllocHeapMemory? I'm just not sure if the latter function is a method of using malloc with a heap?

Sorry for all the questions, I just stumbled across sysmem and become interested

there is an unrar lib but it only does rar2 not rar3.. rar is proprietary there is source out there but its not free.

google is your friend, seriously, did you even bother to try?

[slasher101]

yep i did i found the one that ur talking about (rar2)
but i was wondering if there was any rar3 ones out there

Thx 4 ur reply anyways

...rar is proprietary there is source out there but its not free.

In other words, probably not.

In other words, probably not.

no, the company/guy behind rar provides the code to decompress (but not create) but its not a free software license.

Is there any reason for a prx (as in, a module not an app on its own) to give me errors when its C++ and not C? Whenever I compile a module in C++ it gives me:

/usr/local/pspdev/lib/gcc/psp/4.1.0/../../../../psp/bin/ld: warning: cannot find
entry symbol module_start; defaulting to 0000000000000000
/usr/local/pspdev/psp/sdk/lib/prxexports.o.rodata.sceResident+0x8): undefined
reference to `module_start'
collect2: ld returned 1 exit status
make: *** [heaparea1.elf] Error 1

if the extention is C it works fine...

I'm compiling with -lstdc++ as well...

At the moment its no major biggy, I can get away with using C but when I want to introduce classes things are going to get hairy.

-Aura

[NoEffex]

I'm pretty sure there are some essential differences between the two, so you might have to use extern tags.

[BlackBurd]

Anybody know where theres some samples to how the vlf library works.

Like something simple i was only able to find one and i was to complex for my tiny brain to take in.

[slasher101]

what does that library do...?

ive heard of it but dont know what it does

~!SlasheR!~

its what dark_alex used to make dc7-dc8

with the waves.

it lets you use official sony style application gfx like the side menu update bar license agreement type text and a whole bunch of other stuff.

[slasher101]

thats KOOL as!!!

ill look into it if i figure out anything ill pm u

add -lpspctrl to your makefile

[malliet]

It's giving the same errors again.

[Auraomega]

*Facepalm*

Check the header file in the future please, it'll save us all so many headaches:

Your code:

...
sceCtrlBufferPeekPositive
...

header

...
sceCtrlPeekBufferPositive
...

Use the code tag it looks sloppy as a spoiler or quote.
