How to run this DFB image example on Ubuntu 12.04 64-bit with DirectFB 1.6.3? -

this same illustration runs no problem in older ubuntu 10.10 directfb 1.4.11 , shows yellowish line in center of black screen:

#include <iostream> #include <stdio.h> #include <unistd.h> #include <directfb.h> using namespace std; static idirectfb *dfb = null; static idirectfbsurface *primary = null; static int screen_width = 0; static int screen_height = 0; #define dfbcheck(x...) \ { \ dfbresult err = x; \ \ if (err != dfb_ok) \ { \ fprintf( stderr, "%s <%d>:\n\t", __file__, __line__ ); \ directfberrorfatal( #x, err ); \ } \ } int main(int argc, char **argv) { dfbsurfacedescription dsc; dfbcheck(directfbinit (&argc, &argv)); dfbcheck(directfbcreate (&dfb)); dfbcheck(dfb->setcooperativelevel (dfb, dfscl_fullscreen)); dsc.flags = dsdesc_caps; dsc.caps = dfbsurfacecapabilities(dscaps_primary | dscaps_flipping); dfbcheck(dfb->createsurface( dfb, &dsc, &primary )); dfbcheck(primary->getsize (primary, &screen_width, &screen_height)); dfbcheck(primary->fillrectangle (primary, 0, 0, screen_width, screen_height)); dfbcheck(primary->setcolor (primary, 0xff, 0xff, 0x00, 0xff)); dfbcheck(primary->setsrccolorkey(primary, 0xff, 0xff, 0x00)); dfbcheck(primary->setblittingflags(primary, (dfbsurfaceblittingflags) ( dsblit_blend_alphachannel | dsblit_src_colorkey))); dfbcheck(primary->drawline (primary, 0, screen_height / 2, screen_width - 1, screen_height / 2)); primary->flip(primary, null, dfbsurfaceflipflags(0)); sleep(3); primary->release(primary); dfb->release(dfb); cout << "done!\n"; homecoming 23; }

but same illustration show black screen, no line, in ubuntu 12.04, using directfb 6.3.

the console output is:

any thought why line not drawn? wonder if it's problem 64-bit system?

you meant 1.6.3 version. dont know configure options. illustration mmx support. can reconfigure , reinstall --enable-debug and/or --enable-trace run programs --dfb:debug more info. directfb lot of system call while running can see them strace. old question lately these suggested methods find related problems run directfb apps. goog luck.
