Thank you, I think it may be a problem with my Linux system, the path name may have changed because I switched the system language, I plan to reinstall the system.

hello, Has your problem been solved? I had the same problem. Can you tell me how to solve this difficult problem? thank you .

#5

To be honest, I don’t know where the problem is. I used Ubuntu 19.04 for temporary learning. Recently I bought a new and bigger hard drive, so I reinstalled Ubuntu 18.04.3 and related software, and the problem was solved. Maybe you can solve the problem by reinstalling the software without reinstalling ubuntu.

thank you for youor answer

Hi
did you solve the problem? Or did you reinstall ubuntu as well?

Thanks

I had this issue, I would check the version of gcc and g++ you have. I had version 9 installed, but StaMPS needs version 7.
Install version 7 of both GCC and G++ as your default versions, then delete your StaMPS folder, and reinstall it.

Hi Matt,
I had the same problem. Your solution worked for me.

In my case, the default version of GCC and G++ was 8. I am working on a HPC system, and I do not have admin previledges to install new software. Luckily the system had version 7 of the software. So, I loaded them to replace the newer version.

Before the reinstall of StaMPS (with ‘make’ and ‘make install’) I made shure that I had version 7 for both GCC and G++.

I have tested the method in MATLAB version R2017b which also shown problem with libstdc++.so.6 package. I solved that by adding the following line in my ~/.bashrc file.

alias matlab=‘LD_PRELOAD=/usr/lib64/libstdc++.so.6.0.25 /cm/software/apps/matlab/R2017b/bin/matlab -desktop’

In future, I will test the solution in higer version of MATLAB.

Best regards,
Palash

Helllo everyone! I have problem with running this command mt_prep_snap. When I run “file name_mt_prep_snap_date_file name” does not recognize this command. Could it be because I installed StaMPS incorrectly? Thanks in advance!

#12

please read the instructions regarding the StaMPS_CONFIG file. Once this is sourced correctly, all commands will be recognized.

please see the solution provided here: Segmentation Fault (core dumped) error during mt_prep_snap

#15

For me worked after I run the folder of StaMPS in a Terminal, and then I run the command: source_StaMPS_CONFIG.bash.
Although I applied this when installing StaMPS, but every time I restart my Linux system this configuration was missed and I have to rerun source_StaMPS_CONFIG.bash.

open .bashrc file in /home/Username
Then enter the below line, at the end of the .bashrc file.

export PATH=path of stamps upto bin (/home/username/stamps/bin):$PATH

then run
source .bashrc

It will solve your problem.

dear matt, thanks for you sharing, I uninstalled my gcc and tried to reinstall the gcc -7 version, but I was prompted during the installation that the package was deprecated, how do I install gcc version7 now?
