Error loading shared libraries: libsystemc-2.3.1.so #125

Closed amitrokade47 closed 3 years ago

amitrokade47 commented 3 years ago

I get the following error when I try the wget command error while loading shared libraries: libsystemc-2.3.1.so: cannot open shared object file: No such file or directory

I have systemc on my machine Distributor ID: Ubuntu Description: Ubuntu 20.04.2 LTS Release: 20.04

Can you please let me know how to fix it?

davidepatti commented 3 years ago

Hi, are you sure your are using the automatic script installation, as suggested in the first page? I just used it on ubuntu 21.10 and it worked (...also tried on previous versions)

davidepatti commented 3 years ago

Be sure to remove any pre-existing noxim directory before trying again, I also update the script to avoid a small problem occurrin when repeated installation attempts are made.

amitrokade47 commented 3 years ago

Actually I have systemc-2.3.1 but not systemc-2.3.1.so file? The systemc-2.3.1 I have is in a dir different than /usr/lib . Does the script install systemc library as well ?

davidepatti commented 3 years ago

yes, the install script automatically compiles the required systemc libs and also put the path so that the runtime can find it. Use the script, look at the main page, it's a single command line.

I have used the wget command at the github page, it fails in the end with the same error error while loading shared libraries: libsystemc-2.3.1.so: cannot open shared object file: No such file or directory

davidepatti commented 3 years ago

what is the content of : noxim/bin/libs/systemc-2.3.1/systemc.conf ? that file indicates the path, but it is automatically copied into: /etc/ld.so.conf.d/noxim_systemc.conf

so you should have both file, with the same content.

amitrokade47 commented 3 years ago

Both the files contain <MY_NOXIM_DIR_PATH>/noxim/bin/libs/systemc-2.3.1/lib-linux64 (BTW I am doing all of this on the server, not on my local machine, I dont think that should affect it though)

davidepatti commented 3 years ago

Can you post the log of your compilation? I need only from the last lines, around something like: Libraries have been installed in: <YOUR_PATH_HERE!!>noxim/bin/libs/systemc-2.3.1/lib-linux64

davidepatti commented 3 years ago

what's the content of your noxim/bin ?

amitrokade47 commented 3 years ago

build | libs | Makefile | Makefile.deps | noxim | power.yaml

davidepatti commented 3 years ago

go there, and type "ldd noxim", show the output

if you confirm that looking at file: /etc/ld.so.conf.d/noxim_systemc.conf it contains a path inside which you can find libsystemc-2.3.1.so then type: "sudo ldconfig" it's strange because it's what the script does.

amitrokade47 commented 3 years ago

I added the path you mentioned to LD_LIBRARY_PATH and it started working. Thanks!
