Seems, select/FD_ISSET don't work with dgram sockets (psp)?
I've set the socket now to nonblock (fcntl(fd_dgram_listen, F_SETFL, O_NONBLOCK);) and I'm repeating recvfrom while nbytes > 0. Then it's ok.

bool getServerMessagesDgram() { begin: read_fds = master; timeval tv; tv.tv_sec = 0; tv.tv_usec = 0; if (select(FD_SETSIZE, &read_fds, NULL, NULL, &tv) == -1) { report_error("select failed.")...

never mind, forgot to call pspSdkInetInit...

Haven't found any information about this error (pspkerror.h was no help...)

Is anyone working with the gum texture matrix stack?

Manipulating texture coordinates with sceGuTexOffset is ok, but I couldn't get the texture matrix stack to work (see first post)

ufoz,

I think you are right, I must set the TexMapMode to GU_TEXTURE_MATRIX, but:
- when I leave the 2 other parameters 0, the texture matrix isn't correct
- seems I have to set something else (didn't find info, how to use the 2. and 3. parameter of sceGuTexMapMode)

Hi, I'm trying to manipulate the texture matrix stack with the same steps I use in OpenGL: ScePspFVector3 v; v.x = -0.5; v.y = 0; v.z = 0; sceGumMatrixMode(GU_TEXTURE); sceGumLoadIdentity(); sceGumTranslate(&v); sceGumDrawArray ... but this has no effect (texture is drawn at the same position as...

I have a (maybe stupid) question: Why are the adresses >>16<< byte aligned ? If the cache-line size is 64 byte, and some dirty cache lines get written, couldn't this overwrite some allocated memory (if it was allocated using an uncached pointer) ?? (or does it mean, never allocate 16 byte aligned me...

Ok, didn't make install libpng... Works now...

I installed libpng, the png.h is in c:\cygwin\usr\include\libpng10 and c:\cygwin\usr\include\libpng12, but can't be found when building the pspgl test. Seems I have to set a path somewhere ?

I downloaded pspgl as described in http://www.goop.org/psp/gl/ When trying to build the tests (make && make -C tests clean install), I get some errors, first is "screenshot.c:5:17: error: png.h: No such file or directory" I searched for png.h, it exists in C:\cygwin\usr\include\lib...

strange: I have installed cygwin now only with the packages listed in http://pspupdates.qj.net/lesson01.htm (so not the whole ‘Devel’ category) and get no more "operation not permitted" errors in the toolchain. When I reactivate my first cygwin installation (with full 'Devel'), I get the e...

I've tried to download the files manually and put them in the psptoolchain dir but later in the skript, I get some more "operation not permitted" errors (this time not related to downloading), and the skript stops.

the full error message is "Connecting to ftp.gnu.org|199.232.41.7|:21... failed: Operation not permitted."

I tried with disabled firewall and virusscanner, but same error.

After a new windows xp installation, I'm trying to install cygwin and the psp-toolchain again. I have done the steps as described in http://wiki.pspdev.org/psp:programming_faq. The cygwin installation was ok, but after starting the psptoolchain, I get an "operation not permitted" error (th...

I have made a few glut programs, that run on the pc but have problems on my psp with firmware 1.0. (example code see http://forums.ps2dev.org/viewtopic.php?t=3399) the main problems are: - program with many polygons freezes after a few seconds - depth buffer not working - polys drawn with glVertex a...

here ist the complete (modified) simple.c - if you move a few seconds with the triangle and x buttons the prog hangs, also the depth buffer doesn't work (don't know why) - I tested only on a psp with 1.0 #include <stdlib.h> #include <GL/glut.h> static float zPos = -2.5f; char keys[256]; /******* PSP...

I'm testing based on the pspgl glut-test sample (added some more polygons). I have 2 problems. - can't get the depth buffer to work (tried with glEnable(GL_DEPTH_TEST)) - after a few seconds the prog. freezes on the psp, it works o.k. when just the polygons of the original sample are rendered, any b...

chp,

you are right, sceGuEnable(GU_CLIP_PLANES) changes the behaviour. but how can I set the clip planes ?

it can be reproduced in the gu samples, so I don't think it is something special in my source.
(just take the cube sample, disable the animation, render only the top quad to y = -2 or so and make it bigger)

I'm trying to render some big triangles (2 for a floor). The problem is, that they disappear when they are rendered at a small distance. It is not that parts of them are clipped, they completly disappear. With small triangles no problem. Also no problem, when they are rendered in a greater distance.
