Installation of GATE

Getting Started
1

Hi, I am trying to install GATE on WSL but I am stuck at the step of
ccmake ../Gate-9.4 , and before this step, I am not sure if I should build the directory of gate-build and gate-install within the GATE directory or out of it. When I run the command in the gate-build directory, there is:

 CMake Error: The source directory
 "/~/Geant4/Gate-9.4" does not exist.

Do I have to make my own Gate-9.4 directory?

_Geant4 Version:geant4-11-02-patch-02
_Operating System:WSL (Ubuntu 22.04.3 LTS)
_Compiler/Version:gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0
_CMake Version:cmake version 3.22.1

GATE is a third-party product, so nominally you should contact its support channels for help.

Where are you running ccmake from in relation to the GATE source directory? If you have done, e.g.

$ cd Gate-9.4
$ mkdir gate-build
$ cd gate-build
$ ccmake ../Gate-9.4

then that should work. The error:

would indicate that you ran ccmake /~/Geant4/Gate-9.4 or similar, or that WSL is somehow resolving the path incorrectly.

I see, when I run what you suggested, then the error becomes

CMake Error: The source directory  "/~/Geant4/Gate-9.4/Gate-9.4" does not exist.

so does that mean another Gate-9.4 directory should exist in the gate-build directory?

No, the problem is the path that CMake has been passed as the source directory is somehow getting expanded from a relative path, in your original post cmake ../Gate-9.4 to an absolute path /~/Geant4/Gate-9.4 that doesn’t exist (or maybe isn’t readable).

It’s not clear why that’s happening. Could you post the absolute path on your system to the Gate-9.4 source directory please? Could you also check if there truly is a directory named /~/Geant4/Gate-9.4 present?

Hi, the absolute path is /home/username/jingsyuen/Geant4/Gate (I recloned it and did not rename Gate to Gate-9.4), and in my directory, ~/jingsyuen/Geant4/Gate is present. In the original post, the /~/ was a typo. I am wondering if the error is due to Gate not being in the home directory directly.

O.k., given the paths you have now, I’d expect the following to work:

$ cd  /home/username/jingsyuen/Geant4
$ cmake -S./Gate -B./Gate-build
$ cmake --build ./Gate-build

If it doesn’t please post the full output, and make sure to avoid typos.

In cmake -S./Gate -B./gate-build , I since the directory created was named gate-build, so I changed the command, I am not sure if this is correct, but it created a directory gate-build at the same level as the Gate directory, the output is as follows:

Please, see and follow the Gate install guide here: 2. Compiling GATE V9.4 — GATE documentation where it notes the need to install ROOT.
