先修改 /etc/X11/xorg.conf
Section "Screen"
Identifier "aticonfig-Screen[0]-0"
Device "aticonfig-Device[0]-0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Virtual 3600 1920
Depth 24
EndSubSection
EndSection
重启后，
xrandr --output CRT1 --off;
xrandr --output DFP2 --off;
xrandr --output CRT1 --auto --primary;
xrandr --output DFP2 --auto --right-of CRT1 |

编译时候没有问题
link时候出现
/usr/bin/ld: i386:x86-64 architecture of input file `/usr/lib/gcc/x86_64-
linux-gnu/4.3.3/../../../../lib/crt1.o' is incompatible with i386 output

发帖数: 6336 | 3 装了一个quantlib在mac os x上，然后运行那个example，结果得到下面一堆。请教应
该link或者编译？
谢谢！
instruction在这里：
http://quantlib.org/install/macosx.shtml
run example
g++ -I/opt/local/include/ -I/opt/local/include/boost BermudanSwaption.cpp
-o bermudanswaption -L/opt/local/lib/ -lQuantLib
以后的error：
Undefined symbols for architecture x86_64:

g++ -I/opt/local/include/ -I/opt/local/include/boost BermudanSwaption.cpp \
-o bermudanswaption -L/opt/local/lib/ -lQuantLib
得到i686-apple-darwin10-g++-4.2.1: BermudanSwaption.cpp: No such file or
directory。
然后到/opt/local/include/boost目录下，再次运行上面的命令行，显示下面的内容
g++ -I /opt/local/include/ -I /opt/local/include/boost BermudanSwaption.cpp
-o bermudanoption -
L/opt/local/lib/ -lQuantLib1.0.1
