Hello, You seem to compile SDL in a static manner, and did not include the sdl static library in your project. Do include "sdl_1_3.lib" in your project. Another way in to use the "dynamic" compilation version and use SDL.dll file. Let me know if it work for you, Michael --- On Fri, 11/11/11, ??? <zhaojingda8866 at gmail.com> wrote: From: ??? <zhaojingda8866@xxxxxxxxx> Subject: Errors when compiling the vidgui of pjproject-2.0-alpha2 To: pjsip at lists.pjsip.org Date: Friday, November 11, 2011, 12:12 AM Dear all, I have got the following errors when I'm compling the vidgui: ----------------------------------------------------------------------------------------------------------------------- vidgui.o: In function `main': /root/project/voip/pjsip/pjproject-2.0-alpha2/pjsip-apps/src/vidgui/vidgui.cpp:640: undefined reference to `SDL_InitSubSystem' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjsip-apps/src/vidgui/vidgui.cpp:641: undefined reference to `SDL_GetError' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `put_frame': sdl_dev.c:(.text+0xd7): undefined reference to `SDL_UpdateTexture' sdl_dev.c:(.text+0xe5): undefined reference to `SDL_RenderClear' sdl_dev.c:(.text+0x111): undefined reference to `SDL_RenderCopy' sdl_dev.c:(.text+0x11f): undefined reference to `SDL_RenderPresent' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `get_cap': sdl_dev.c:(.text+0x185): undefined reference to `SDL_GetWindowWMInfo' sdl_dev.c:(.text+0x1b2): undefined reference to `SDL_GetWindowFlags' sdl_dev.c:(.text+0x1dd): undefined reference to `SDL_GetWindowPosition' sdl_dev.c:(.text+0x1fd): undefined reference to `SDL_GetWindowSize' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `sdl_destroy': sdl_dev.c:(.text+0x2c7): undefined reference to `SDL_DestroyTexture' sdl_dev.c:(.text+0x2e3): undefined reference to `SDL_DestroyRenderer' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `sdl_create_rend': sdl_dev.c:(.text+0x430): undefined reference to `SDL_CreateRenderer' sdl_dev.c:(.text+0x46c): undefined reference to `SDL_CreateTexture' sdl_dev.c:(.text+0x4df): undefined reference to `SDL_CreateWindowFrom' sdl_dev.c:(.text+0x554): undefined reference to `SDL_CreateWindow' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `sdl_destroy_all': sdl_dev.c:(.text+0x605): undefined reference to `SDL_DestroyWindow' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `sdl_quit': sdl_dev.c:(.text+0x697): undefined reference to `SDL_Quit' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `find_stream': sdl_dev.c:(.text+0x747): undefined reference to `SDL_GetWindowID' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `sdl_init': sdl_dev.c:(.text+0x7ae): undefined reference to `SDL_Init' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `resize_disp': sdl_dev.c:(.text+0x1007): undefined reference to `SDL_RenderSetViewport' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `set_cap': sdl_dev.c:(.text+0x1072): undefined reference to `SDL_HideWindow' sdl_dev.c:(.text+0x1084): undefined reference to `SDL_ShowWindow' sdl_dev.c:(.text+0x10a7): undefined reference to `SDL_SetWindowSize' sdl_dev.c:(.text+0x10d9): undefined reference to `SDL_SetWindowPosition' /root/project/voip/pjsip/pjproject-2.0-alpha2/pjmedia/lib/libpjmedia-videodev-i686-pc-linux-gnu.a(sdl_dev.o): In function `handle_event': sdl_dev.c:(.text+0x116d): undefined reference to `SDL_PollEvent' collect2: ld returned 1 exit status make: *** [vidgui] ?? 1 -------------------------------------------------------------------------------------------------------------------- The pjproject-2.0-alpha2 has been compiled successfully and the pjsua can be used.I have also installed the latest version of SDL1.3.
