Hi Kolesar, > when compiled this test program with: > gcc -c test_library.c -o test_library1.o Okay, looks good. > g++ test_library1.o -o test_library1 -ldl Why are you using g++? Why are you not using gcc? Do you need g++? Unless there is more to your example than you are providing (e.g., it's C++ source, not C source), it seems that g++ should not be necessary here. > but, when i build with: > gcc -ldl test_library.c -o test_library Why are you specifying -ldl out of order? What happens when you do: gcc test_library.c -o test_library -ldl Does that make a difference? You used g++ before. Do you need g++? g++ test_library.c -o test_library -ldl Does that make a difference? HTH, --Eljay
