Normally everything is fine with AllPix Squared, and without any modifications, sometimes the following two problems are suddenly encountered.
After running… /bin/allpix -c xxx.conf, the following error is displayed
can not load library /cvmfs/sft.cern.ch/lcg/views/LCG_101/x86_64-centos7-clang12-opt/lib/ibRio.so undefined symbol:_ZNK6TClass14NewObjo
After source etc/scripts/setup_lxplus.sh, the following error is reported
Detected CentOS Linux 7
Compiler type set to LLVM, version clang12.
-bash: /cvmfs/sft.cern.ch/lcg/views/LCG_99/x86_64-centos7-clang12-opt/setup.sh: No such file or directory
yes
both could be connected with (temporary) issues connecting to CVMFS. However, it’s interesting that in one case, LCG_101 is loaded while in the other there is a reference to LCG_99.
May I ask which version of Allpix Squared you are using (allpix --version) and how you installed it?
First,allpix --version
source /cvmfs/clicdp.cern.ch/software/allpix-squared/1.6.1/x86_64-centos7-gcc10-opt/setup.sh
allpix --version
Allpix Squared version v1.6.1
built on 2021-01-28, 17:30:48 UTC
Second, Install steps:
1.source /cvmfs/clicdp.cern.ch/software/allpix-squared/1.6.1/x86_64-centos7-gcc10-opt/setup.sh
2. git clone Cern Authentication allpix-squaredquared.git allpix-squared
3.cd allpix-squared
4.mkidr build
5.cd build
6.cmake …
7.make -j4 install
8.source etc/scripts/setup_lxplus.sh
Run simulations!
Are there any problems with the above steps?
The second part of your commands are basically the installation of your own version of Allpix Squared - in that case you used the very latest master version which is in active development. For simulations this is not recommended. So if you really need your own version to tinker with, I would recommend the following recipe:
git clone https://gitlab.cern.ch/allpix-squared/allpix-squared.git
cd allpix-squared
git checkout v2.1.0
source etc/scripts/setup_lxplus.sh
mkdir build && cd build
cmake ..
make install -j4
But mixing the two options will mix the dependencies - the Allpix Squared v1.6.1 has been built with different dependencies than the master development version you are then compiling.
I followed you steps,but have a question
when I source etc/scripts/setup_lxplus.sh
-bash: /cvmfs/sft.cern.ch/lcg/views/LCG_99/x86_64-centos7-clang12-opt/setup.sh: No such file or directory
yes
I may have found the problem, when make install -j4, it says Disk quota exceeded.
Maybe I can download the previous version instead of the latest one.
Do you have any recommendations for a historical version? How do I download it?
as stated above - if you are working on a machine that has CVMFS there is no need to download anything at all. Please just call the one single source command to load everything you need from CVMFS. No cmake, no make.
The disk space will however still be a problem because CVMFS caches files on your local disk and this can be several GB. Allpix Squared itself is only a couple of 10MB.
Thanks for your reply,I need to change the code so I need my own installation.I didn’t have problems with disk space when I installed versions 1.3 and 1.6.1 before, could it be because of the latest version? May I still install the previous versions?
And can Allpix Squared analogue the silicon microstrip detectors?
your disk space has nothing to do with Allpix Squared. The full repository is 10MB (!).
Yes, of course you can compile previous versions, either by downloading the respective tag or by cloning the git repository and checking out the tag. However, I strongly recommend staying up-to-date and instead to clear up some disk space (du -hs ~/* might help…)
