Garfield installation issue

[hschindl]

Hi,
the square brackets are meant to indicate optional arguments. If you are happy with the default settings you can just type:
cmake $GARFIELD_HOME

[hschindl]

One more thing: from what I can see in the screenshot you sent, you set the environment variable $GARFIELD_HOME to /home/ahmer/Desktop/garfield, but then you cloned the repository to /home/ahmer/Desktop/garfield/garfield-2 and created your build directory in /home/ahmer/Desktop/garfield. I’m not sure if this is what you intended to do, but if it is, you need to modify the argument of the cmake command:

cmake /home/ahmer/Desktop/garfield/garfield-2

Ok, so you cloned the repository to the directory /home/ahmer/Desktop/garfield/garfield/garfield-2. If that is what you want, please do the following:

1. Source the thisroot.sh script. I’m assuming your root installation is located in /home/ahmer/Desktop/root. If this is not the case, please adapt the path accordingly.
   source /home/ahmer/Desktop/root/bin/thisroot.sh
2. Set the environment variable GARFIELD_HOME to point to the directory that contains the Garfield++ source tree.
   export GARFIELD_HOME=/home/ahmer/Desktop/garfield/garfield/garfield-2
3. Follow the usual instructions for building the project:

cd $GARFIELD_HOME
mkdir build
cd build
cmake ..
make
make install
. $GARFIELD_HOME/build/setup.sh

Or maybe you’d prefer your Garfield++ source directory to be /home/ahmer/Desktop/garfield (which I think is what you wanted in the first place)? Then please first clean out /home/ahmer/Desktop/garfield:

rm -rf /home/ahmer/Desktop/garfield/Build
rm -rf /home/ahmer/Desktop/garfield/garfield
rm -rf /home/ahmer/Desktop/garfield-2
rm -rf /home/ahmer/Desktop/garfield-v2
rm /home/ahmer/Desktop/garfield-v2.tar.gz

Then redo the git clone step

git clone https://gitlab.cern.ch/garfield/garfieldpp.git $GARFIELD_HOME

and follow the standard installation instructions.

Hi,
can you provide a bit more details? At which point during the installation did you get stuck?

[ahmer_k]

thank you for your time hschindl. i’ll do and let you know. and my root is definitely on the Desktop as you were saying. i have to source the thisroot.sh before cmake.

[ahmer_k]

i removed all the filed and directories to install and un tar the file again but now it is again giving error which should not be there. i export the file as shown.

[ahmer_k]

then i again make same directories ans source the thisroot.sh but on the other hand now again git clone making issue that directory is not empty. last time when i did it the issue was resolved this way.

[ahmer_k]

@hschindl

export GARFIELD_HOME=/home/ahmer/Desktop/garfield/garfield/garfield-2

i export this in bashrc as you told thats why issue is coming or i did something wrong?

[hschindl]

The problem is that you (1) keep changing paths and (2) try git cloning into a non-empty directory (which is not what I asked you to do). Let’s try to start from scratch, delete everything in /home/ahmer/Desktop/garfield/, and do a fresh clone. So, please, do the following:

rm -rf /home/ahmer/Desktop/garfield/
export GARFIELD_HOME=/home/ahmer/Desktop/garfield/
git clone https://gitlab.cern.ch/garfield/garfieldpp.git $GARFIELD_HOME
cd $GARFIELD_HOME
mkdir build
cd build
source /home/ahmer/Desktop/root/bin/thisroot.sh
cmake $GARFIELD_HOME
make
make install
source $GARFIELD_HOME/build/setup.sh

[ahmer_k]

oo… thanks dear i’ll do this according to your guidance.

[ahmer_k]
