Hi everybody,  
I have compiled my code based on the ALPS libraries () and CMake build system with IBM compiler xlC 11.1 on AIX 6.1 at the latest patch level running on an IBM SP Power 6 machine for high-performance computing.  
When I run the executable I receive this error message:

```nohighlight
-bash-3.2$ ./hubbardfly 
exec(): 0509-036 Cannot load program hubbardfly because of the following errors:

```

Can somebody help me ? I suspect something related to environment variables (setting the path for libalps.so does not work either) or maybe some compiler option to be passed.

Best regards,  
Jessica

Hi,

I am not a developer, just SA, but I asked around and this is what my developers are saying helped in the older versions - you may want to give it a try:

if "-G" and "-qtwolink" are failing, try "-brtl"

Thank you very much for your reply,  
unfortunately the -brtl option does not solve the problem, I'll try with the other two ones and I'll let you know.  
Best,  
Jessica
