Hi Xiaozhu, I have double checked and both libraries that you pointed out were of the same version. I have tried to run the program with one or the other and none of them are found by Dyninst (the same error persists). Also, maybe it's very obvious but, I have noticed if I delete *DYNINST_API_RT_LIB* and/or *DYNINSTAPI_RT_LIB* environment variables, the error does not change either.
Finally, I have also installed Dyninst 9.3.0 in a Lubuntu v17.10 32 bit VM and my application seems to work (I haven't been able to make v9.3.2 work with the Counter Mutator example in Lubuntu) however, I would like to make it work on the CentOS 7. All of that makes me think that maybe the problem stems from the dependencies or something that I am not doing well, but I am definitely not sure as I could install Dyninst in both machines without any errors. What would you recommend me that I try next? Thanks again for your help, Alberto Olmo. 2018-04-25 17:27 GMT+02:00 Xiaozhu Meng <[email protected]>: > Hi Alberto, > > From your log for the successful run, it seems like you have multiple > instances of Dyninst installed: one in > /home/aolmo/soft/dyninst-9.3.2/install/lib/ > and the other one in /usr/local/lib/.
