Hi,
I am working on gcc version 3.4.4. I successfully compiled all the
source files and able to build .exe and .dll. I am able to debug the
code properly using gdb/ddd. But while I tried to simulate the code, I
am facing problems. It is not able to simulate. .dll is not even
loading into simulator. What might be the problem.
Are you getting a compiler/linker error or a runtime error? Sounds like,
from the above, that you are able to compile but the program fails to
find the dll. If that is the case you need to make sure the
LD_LIBRARY_PATH environment variable is setup so that it has the
location of the DLL in it.
