GRX2.4.5 and MinGW/Cygwin
by Demmer, Thomas 15 Jan '03

15 Jan '03

Hi all, I have managed to compile GRX under Cygwin with gcc -mno-cygwin (this is essentially just using MinGW and MinGW-Runtime). gcc is version 3.2, just for the record. After some minor changes, it also compiles and links without warnings as a native cygwin application. It just doesn't run and hangs somewhere in GrSetMode(). Can anybody enlighten me what is missing to complete the port to native Cygwin?

Transparent PNG
by Tamas Levente 01 Jan '03

Hey, did anybody try to have two transparent pngs displayed over each other? I tried to load the second over the first one, after bitblt ing the first to the screen, but it seems somehow the second one is not loaded perfectly it has noise in the background. I'm using it on linux with vesa. Can anybody help me?

Hi, I have a Linux Framebuffer working OK with 256 colors (8bpp). The great thing is that support is already built in the library. The odd thing is that it is not 'activated', and I don't know why. File vd_lnxfb.c, function build_video_mode, add this: ... switch( fbvar.bits_per_pixel ) { case 8: mp->bpp = 8; ep->mode = GR_frameSVGA8_LFB; ep->flags |= GR_VMODEF_LINEAR; ep->cprec[0] = fbvar.red.length; ep->cprec[1] = fbvar.green.length; ep->cprec[2] = fbvar.blue.length; ep->cpos[0] = fbvar.red.offset; ep->cpos[1] = fbvar.green.offset; ep->cpos[2] = fbvar.blue.offset; break; ..... And that's all. Now you have support for 8 bpp framebuffer. I have a 4bpp (16 colors) framebuffer too. If anyone is interested ask me directly. Some time ago I offered it to be included as standard driver in grx, but nobody was interested. I've added support for palette too, and is working for me. But this is an embedded hardware, and I'm not sure that it works for everyone: static void loadcolor( int c, int r, int g, int b ) { __u16 red, green, blue, transp; struct fb_cmap cmap; red = (r << 8); green =(g << 8); blue = (b << 8); transp = 0; cmap.start = c; cmap.len = 1; cmap.red = &red; cmap.green = &green; cmap.blue = &blue; cmap.transp = &transp; ioctl(fbfd, FBIOPUTCMAP, &cmap); } For this function to be called, in the function build_video_mode replace ep->loadcolor = NULL; with ep->loadcolor = loadcolor; Excuse me, Mariano. I wanted to talk with you about those things, but I've been (and I am) VERY pressed and I simply forgot it.

need help
by Wolfgang Schilling 07 Dec '02

Dear sirs, my first trial with GRX245 failed. After making and installing without svgalib-support the Linux console framebuffer driver cannot be found. But the direct access to the fb device (/dev/fb0) works fine. Setting with GrSetDriver(drvspec) with drvspec="linuxfb gw 800 gh 600 nc 256" dosn't make anything. Also setting of GRX20DRV. What must I do? Do I need a separate driver? Where can I get it? Looking forward to your answer. Thanks for your trouble. Wolfgang Schilling

GRX is at > version 2.4.5 now. See http://www.gnu.de/software/GRX/ for more. Perhaps I was too lazy to screem ... (and I didn't want to peek into much details at that time) I also got similar problem when building grx-2.4.5 for Linux using gcc-3.2 although for different files. I workarounded it by specifying optimization -O1 for file where I had it. This seems to be GCC problem the problem appeared for me with -O2 but not with -O1. I haven't tried to build grx-2.4.5 for DJGPP yet, but anyway one can try to specify decrease optimization level for files where failure happens as workaround. Andris
