    Compiling is OK and able to create .o files , but when we link those files using g++ -o
    It is giving us errors like

    we are using the commands :-

    g++ -c sample1.cpp

    g++ -c sample2.cpp

    g++ -o out sample1.o sample2.o -L/usr/mqm/lib64 -limqb23ia -limqb23ia_r -limqs23ia.a -limqs23ia_r.a

    The required lib files exist in both /usr/mqm/lib64 and current working dir .

    It seems the complier not able to find mqlibraries

    Can you guys able to help on this ?

    Ex- g++ -c -Wl, -berok sample1.cpp
