install flashplayer on Linux 64 machine
In linux 64 firefox, you can not browse flash content by default, you will have to download the linux 64 version library libflashplayer.so from http://labs.adobe.com/downloads/flashplayer10_square.html, then search libflashplayer.so in the computer and replace them with the 64 bit version.

graphic card driver problem on CentOS
I solved the graphic card driver problem today. There are some hints that let me know my graphic card is not working properly.
1)I ran 'bench' in Matlab, the result shows the 2D and 3D function is extremely poor (poor than my laptop) while other test figure are very good.
2)When I use firefox, I can not use WebGL as before. My firefox is the latest beta version, it should work.
3)When I ran OpenGL program, it reports error: extension "GLX" missing on display ":0.0".
4)I found my screen is not as shape as it supposed to be.
I googled the GLX problem and found it is related to the graphic card. Here is the article http://wiki.centos.org/HardwareList/Nvidia_Graphics. Followed the instruction, I have my graphic card driver installed. After the installation the screen became nice and shape. It also works properly on WebGL and OpenGL things. And I run the matlab bench again, it turns out to be super fast now.

Compile Opensees on CentOS
Here is a record of compiling OpenSees in CentOS. I edit my Makefile based on Makefile.def.LINUX_RedHat_ENTERPRISE and then start compiling. I posted my Makefile.def.CentOS in another blog.
First Error is:
After googling, I find SuperLU.h is a old version, change :
Second Error:
It seems to get stuck at /home/GL/OpenSees/SRC/tcl , so I go to this directory and type make, after making sure all '.o's are generated, I go back to opensees, type make. The error has gone.
Then I get the error about BJtensor.
I googled it and find it has something to do with C++Flags, which I don't know much about it so far. I change the flag to this:
Then I go back to home directory and type make. This time it compiled for a few minutes. After that, the compiler says all libraries are built and it is going to link them. While linking, some errors occur:
It has something to do with Tk library, since these functions are implemented in Tk. So just add TK library (libtk8.4.so) into this variable:
Another error is:
`amd_order' function is implemented in AMD library, which needs to be compiled. Do things below to get rid of this error:
1)add a line:
AMDdir = $(HOME)/OpenSees/OTHER/AMD
2)add $(AMDdir) to DIRS
3)add a line:
The error above tell us OpenSSL library needs to be linked. By adding -lssl to MACHINE_SPECIFIC_LIBS to get rid of the error. i.e:
The above is a brief record of the main compiling process. But there are many other tricky things:
My CentOS do have tcl/tk at 8.4 version. But it does not comtain a tk.h file, very strange... So I download it manually from some website and put it into the TCL_INCLUDES directory. Then the compiler report 'Tk_SafeInit' is not declared... So I edit the tk.h and declare 'Tk_SafeInit', although I have no idea what it is. I just copy the way they declare 'Tk_Init' and change the name. Then it will work.
Another tricky thing is when you use command g++ -l(library) to specify the library you want to link, it can only search for something with the file named *.so, it can not find something like *.so.0.0, so if the library file's name is *.so.0.0, you have to make a link *.so pointing to it. Use the command:
ln -s libraryname.so.0.0 libraryname.so.
First Error is:

After googling, I find SuperLU.h is a old version, change :

to
SUPERLUdir = $(HOME)/OpenSees/OTHER/SuperLU_3.0/SRC
Second Error:

Then I get the error about BJtensor.

I googled it and find it has something to do with C++Flags, which I don't know much about it so far. I change the flag to this:
C++FLAGS = -Wall -D_LINUX -D_UNIX -D_MYSQL -D_TCL84 $(GRAPHIC_FLAG) $(RELIABILITY_FLAG)\
$(DEBUG_FLAG) $(PROGRAMMING_FLAG) -O3 -ffloat-store -D_HTTPS
Then I go back to home directory and type make. This time it compiled for a few minutes. After that, the compiler says all libraries are built and it is going to link them. While linking, some errors occur:

......tkAppInit.cpp:(.text+0x37): undefined reference to `Tk_Init'
It has something to do with Tk library, since these functions are implemented in Tk. So just add TK library (libtk8.4.so) into this variable:
TCL_LIBRARY = /usr/local/tcl/lib/libtcl8.4.so
so it is now:TCL_LIBRARY = /usr/lib64/libtcl8.4.so /usr/lib64/libtk8.4.so
Another error is:
