I didn't have “ (!) Direct/Modules: Unable to dlopen“ error, did you start your program with "sudo"? and I also have have some errors, but directFB test(attachment) can pass on my pc. You may alse need direcfbrc file to configure directFB, and init it with command 'echo -e "mode=1366x768\nwm=default\ndepth=32\nsystem=x11" > ~/.directfbrc'. 在 2015-10-23 05:24:32，"Albert Freeman" <[email protected]> 写道： >On 22 October 2015 at 15:35, Albert Freeman <[email protected]> wrote: >> On 22 October 2015 at 15:31, Albert Freeman <[email protected]> wrote: >>> On 22 October 2015 at 12:25, 刘涛 <[email protected]> wrote: >>>> Attachment need approval and main output see below: >>>> >>>> Build options: >>>> Version 1.7.6 >>>> Linux powered yes >>>> Install prefix /usr >>>> Config files in /usr/etc >>>> Build shared libs yes >>>> Build static libs no >>>> Module directory ${exec_prefix}/lib/directfb-1.7-6 >>>> CC gcc >>>> CXX g++ >>>> LD /usr/bin/ld -m elf_x86_64 >>>> CPPFLAGS -D_REENTRANT >>>> CFLAGS -Wall -Wstrict-prototypes -Wmissing-prototypes >>>> -Wno-strict-aliasing -Werror-implicit-function-declaration -O3 -g2 >>>> -ffast-math -pipe -D_GNU_SOURCE -std=gnu99 >>>> -Werror-implicit-function-declaration >>>> CXXFLAGS -Wall -Wno-strict-aliasing -std=c++0x -g -O2 -O3 >>>> -g2 -ffast-math -pipe -D_GNU_SOURCE >>>> LDFLAGS >>>> LIBS -ldl -lrt -lpthread >>>> DYNLIB -ldl >>>> RTLIB -lrt >>>> THREADFLAGS -D_REENTRANT >>>> THREADLIB -lpthread >>>> >>>> Misc options: >>>> Multi Application Core no >>>> Fusion Kernel Device yes >>>> Fusion message size 16384 >>>> Fluxed args size 1024 >>>> One (IPC) no >>>> Voodoo (network support) no >>>> Pure Voodoo (net only) no >>>> DiVine (virtual input) no >>>> FusionDale no >>>> Debug supported yes >>>> Debug enabled no >>>> Trace support no >>>> MMX support yes >>>> SSE support yes >>>> GCC Atomics usage no >>>> Network support yes >>>> Include all strings yes >>>> Software Rendering yes >>>> Smooth SW Scaling no >>>> Dithering none >>>> Dithering 565 none >>>> zlib compression no >>>> Using setsockopt yes >>>> >>>> Building Tests no >>>> Building Tools yes >>>> >>>> Building System Modules: >>>> Linux FBDev support yes >>>> Generic /dev/mem support yes >>>> Mesa/DRM/KMS support yes -I/usr/include/libdrm >>>> -lGLESv2 -lEGL -ldrm -lgbm >>>> DRM/KMS support no >>>> PVR2D no >>>> EGL no -I/usr/include/libdrm -lGL >>>> -lEGL >>>> X11 support yes -lX11 -lXext >>>> X11/VDPAU support no >>>> OSX support no >>>> SDL support no >>>> VNC support no >>>> >>>> Building Window Manager Modules: >>>> Default yes >>>> UniQuE no >>>> SaWMan no >>>> >>>> Building Image Provider Modules: >>>> GIF yes >>>> JPEG yes -ljpeg >>>> PNG yes -I/usr/include/libpng12 >>>> -lpng12 >>>> Imlib2 no >>>> PNM yes >>>> SVG no >>>> BMP yes >>>> WEBP no >>>> JPEG2000 no >>>> MPEG2 yes >>>> TIFF no >>>> >>>> >>>> >>>> Building Video Provider Modules: >>>> GIF yes >>>> Video4Linux yes (v2: no) >>>> MNG no >>>> Gstreamer no (v1: no) >>>> with FusionSound no >>>> AviFile no >>>> Flash no >>>> Libmpeg3 no >>>> OpenQuicktime no >>>> Xine no >>>> Xine/VDPAU no >>>> Swfdec no >>>> FFmpeg no >>>> >>>> Building Font Modules: >>>> FreeType2 yes -I/usr/include/freetype2 >>>> -lfreetype >>>> LinoType no >>>> Default font yes >>>> >>>> Building FusionSound no >>>> >>>> Building Graphics Drivers: >>>> 3Dfx Voodoo yes >>>> ATI Mach64 yes >>>> ATI Rage 128 yes >>>> ATI Radeon no >>>> Cirrus EP9X yes >>>> Intel i810 yes >>>> Intel i830 yes >>>> Matrox yes >>>> NeoMagic yes >>>> NSC Geode yes >>>> nVidia yes >>>> PVR2D no >>>> PXA 3xx yes >>>> Renesas R-Car GP2D no >>>> Renesas SH7722/SH7723 no >>>> S3 Savage no >>>> SiS 315 yes >>>> TI Davinci no >>>> TI OMAP no >>>> TVIA CyberPro no >>>> VIA CLE266 no >>>> VIA UniChrome no >>>> VMWare no >>>> VDPAU no >>>> -- >>>> OpenGL yes (GLX: yes) >>>> OpenGL ES 2.0 yes (Mesa: yes, PVR2D: no) >>>> -I/usr/include/libdrm -DGLES2_MESA >>>> -lGLESv2 -lEGL -ldrm -lgbm >>>> >>>> IDirectFBGL-EGL yes -I/usr/include/libdrm -lGL -lEGL >>>> >>>> Building Input Drivers: >>>> DBox2 Remote no >>>> DreamBox Remote no >>>> Dynapro Touchscreen no >>>> ELO Touchscreen no >>>> Gunze Touchscreen no >>>> H3600 Touchscreen no >>>> Input Hub yes >>>> Joystick yes >>>> Keyboard yes >>>> Linux Input yes >>>> LiRC yes >>>> MuTouch touchscreen yes >>>> Zytronic touchscreen yes >>>> PS/2 Mouse yes >>>> Serial Mouse yes >>>> SonyPI Jogdial yes >>>> tslib yes -lts >>>> ucb1x00 Touchscreen no >>>> WM97xx Touchscreen yes >>>> >>>> >>>> >>>> >>>> 在 2015-10-22 20:14:41，"刘涛" <[email protected]> 写道： >>>> >>>> Sorry , add attachment for this time. >>>> >>>> >>>> 在 2015-10-22 20:13:36，"刘涛" <[email protected]> 写道： >>>> >>>> I use "./configure --prefix=/usr --enable-idirectfbgl-egl" to configure >>>> DirectFB-1.7.6 and please see attachment config.log for output. >>> I was really really wrong about what DirectFB can support.
