OpenSees 64 Ubuntu

[MDSmith526]

I'm brand new to Linux. I'd like to install a 64 bit version of OpenSees, but I can't find a very clear instruction guide on how to do that with the latest version.

I know I need some dependencies, and some of those have to be 64-bit version. I know that I also need to modify the makefile.def. I'm not very confident I know how to do either one of those things correctly. Could someone give me guidance? I found the link for installing OpenSeesMP on Linux. Is it the same, except not the MP version?

Thanks

You need to compile the opensees source code to a 64 bit binary on a linux system. To do that, you have to modify the makefile.def to set things such as source code directory, compilers, and quite few flags. Then you can type 'make' in the opensees main directory and will see compiling informations and/or errors.

Of course. I can compile OpenSees in general. What I'm asking is, which dependencies are needed in 64 bit. For instance, I know I need the 64 bit version of TCL8.5. Do I need a special BLAS or LAPACK or anything else?

if you look at the Makefile.def.EC2??? there is a list of packages that need to be installed if you have a plane minimal operating system w/o compilers and other needed items. tcl is one of the packages that gets installed.

I built opensees using the instructions in the makefile.def, but the text when I run it says OpenSees blah blah (rev 6248) 32-Bit. I ran OpenSees and asked tcl what it's pointer size was and it was 8, so at least tcl is 64 bit. Did I miss something else?

I just ran a fairly large model and it is using 3.9GB of memory, so I'm guessing it is 64-bit, whether it says it is or not...? Also, if anyone is interested, I built it using the new Windows 10 Ubuntu and it ran like a charm.

ignore the text posted to the screen .. the compiler nor exe is actually obtaining info from the MAkefile or system about whether the 32 or 64 bit version being compiled .. if you want to change it it is in SRC/tcl/tclMain.cpp
