Linux Cimg链接eclipse错误

在ubuntu eclipse中，我想使用img库：

我的g++选项：

   -I"/home/lukas/Desktop/ressss/resolution_F/re_fol/CImgLib"
    -I"/home/lukas/Desktop/ressss/resolution_F/re_fol/Eigen" -O0 -g3 -Wall
   -c -fmessage-length=0 -L/usr/X11R6/lib -lm -lpthread -lX11   -lX11
  -ltiff -ljpeg -lpng -llapack -lGLU -lGL -ldc1394  -L -lXext -pthread

仍然会收到此错误：

我尝试了一切。重启，许多选项，…gcc 4.6或gcc 4.7…

您需要将代码与X11和pthread库链接起来。 可能您只需要在项目首选项的某个位置添加这些编译器选项：

-lpthread -lX11
