Dear Xiaozhu, Thanks to your advice I have managed to know in what lines the problems stems from and, as you pointed out, the error comes from these two lines:
bool result = SymtabAPI::Symtab::openFile(symt_obj, fileName); > if( !result ) return false; Apparently, the var *result* becomes 0 after the *openFile* function fails. The value that *symt_obj* has is *0 *(after the call ends) and the *fileName *is just the name of my app. Maybe I am missing something... In addition, I have tried to install the PR that you sent me but I am getting another error while executing the cmake: it cannot find *ddb.db*, *params.db* nor *unistd.db *from *unstrip_src*. I am attaching the whole configure log to this email in the event you wanted to see it. Thank you !
