Used VMD 1.9.1 today and the process is as follows:
1. Download the installation package
The download address is http://www.ks.uiuc.edu/Research/vmd/, select the installation package suitable for your system.
My system is Centos 6.3, so the downloaded installation package is: vmd-1.9.1.bin.LINUXAMD64.opengl.tar.gz
2. Unzip the package
tar -zxvf vmd-1.9.1.bin.LINUXAMD64.opengl.tar.gz , the vmd-1.9.1 folder will be generated in the current directory
3. Enter the directory configuration
cd vmd-1.9.1
./configure LINUXAMD64
(The system does not prompt)
./configure
System prompt: using configure.options:LINUXAMD64
Note: If you do not execute ./configure LINUXAMD64, directly executing ./configure system will report an error:
LINUX OPENGL FLTK TK ACTC IMD SPACEBALL LIBTACHYON VRPN NETCDF TCL PYTHON PTHREADS NUMPY SILENT
4. Compile
cd src
make install
5. Modify environment variables
VMD is installed under /usr/local/bin by default, so modify the ~/.bashrc file, add /usr/local/bin to the PATH, and source ~/.bashrc to ensure that the modification takes effect
6. Install the freeglut library if needed
The operation of VMD requires the OPENGL library. Before running VMD, make sure that the relevant libraries have been installed correctly. I'm generally used to using freeglut, so my install command is:
yum install freeglut*
7. Run VMD
Just type vmd in the terminal.
The most perplexing problem today is that after the installation on the first machine, core appears when running vmd. Since the machine is running a test program, it is inconvenient to troubleshoot. For the second machine, the same steps are installed, and it runs successfully!
The systems of both machines are Centos6.3.
Hope to find out why soon.
