Below function calls are resulting in compilation errors in RHEL 7.6 with c++11 compiler option. But compiles successfully with RHEL 6. Please let me know what's the issue. Whether STL function definitions and templates has changed between RHEL 7.6 and RHEL 6 .Also please suggest how to resolve this compilation errors.
1. Funcation call:
outputSimArgMap->insert(std::make_pair($1, (SimArgList*) NULL));
Compilation error :
error: no matching function for call to ‘CommHandler::SimArgMap::insert(std::pair<char*, CommHandler::SimArgList*>)’
outputSimArgMap->insert(std::make_pair($1, (SimArgList*) NULL));
