I installed the latest ScipOptSuite (7.0.2) using the self-extracting archive (yes, after installing the required packages gcc g++ gfortran liblapack3 libtbb2 libcliquer1 libopenblas-dev libgsl23 as demanded at the SCIP download site) and if I navigate into the newly created directory (i.e., /home/stefan/SCIPOptSuite-7.0.2), I can start SCIP via ./bin/SCIP:

However, when I try to start GCG via ./bin/GCG, I get the following error:
./bin/gcg: error while loading shared libraries: libscip.so.7.0: cannot open shared object file: No such file or directory
If I navigate into the lib directory to check its content, here is what I get:

I think it should be possible to start GCG from an installation via the self-extracting archive, but I cannot get it to work. It seems to me that there is a reference to the file libscip.so.7.0.2.0 which does exist, but it does not seem to work. Where is my mistake? Thanks for any help!
I had the same issue and this fixed it for me (although my installation version was v7.0.3).
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/SCIPOptSuite-7.0.3-Linux/lib
Note this only applies to the terminal instance the line was run in (so once it's closed you have to run the line again in another terminal instance to reapply this change).
