I am using amazon ec2 with vaa3d and am having trouble with the missing library files error. I have tried to follow the build linux instructions, but I am still having trouble. I am working as root user with v3d_external in that directory and have set the path as export LD_LIBRARY_PATH= ~/v3d_external/v3d_main/common_lib/lib/. I am getting an invalid identifier error. I am not sure if I have a path error or a syntax error, but any help would be appreciated.

The path looks OK.

Can you provide more information about the error?

This is what I was using and the error I got:

[root@ip... bin]# ./vaa3d
./vaa3d: error while loading shared libraries: libtiff.so.5: cannot open shared object file: No such file or directory
[root@ip... bin]# export LD_LIBRARY_PATH= ~/v3d_external/v3d_main/common_lib/lib/
-bash: export: '/root/v3d_external/v3d_main/common_lib/lib/': not a valid identifier

I wrote it into my bashrc as well and got the same error.

Thank you for the help!

No space between "=" and '~"

use this one instead: export LD_LIBRARY_PATH=~/v3d_external/v3d_main/common_lib/lib/

Thank you. Sorry it was such a simple mistake. 

Now I am getting a cannot connect to x server error. is that just an internet connection issue?

You may have to google it to find the solution. Should be very straightforward.
