Hi everyone,
I am going to install MRtrix on Linux. But, this does not compile on my systems due to following error which is related to memory error:
I am grateful if you could give me any suggestion in order to solve this problem and install it successfully.
Best,

Hi Benham,
Yep, that looks like a typical out-of-memory issue, as described in the documentation [here](http://mrtrix.readthedocs.io/en/latest/troubleshooting/compiler_error_during_build.html). Give the fix suggested in that page a try, and let us know if it works.
Rob
