<div dir="ltr">Hi Sharon,<div><br></div><div>It looks like your system ran out of RAM. Or you've made a lot of CPU cores available to the VM...? If the latter, you can try to restrict how many cores 'build' will use while compiling using the NUMBER_OF_PROCESSORS environment variable, like this:<br></div><div><br></div><blockquote style="margin:0px 0px 0px 40px;border:none;padding:0px"><div><font face="monospace, monospace">$ NUMBER_OF_PROCESSORS=1 ./build</font></div></blockquote><div><br></div><div>If that's not sufficient, you'll need to increase the amount of RAM your VM is set to use. Unfortunately, some of the code is very demanding on the compiler, and it ends up using gigabytes of RAM in the process. Thankfully, you should only need the extra RAM during the 'build' cycle - although the chances are if it's struggling to build now, it'll probably struggle with large datasets like the HCP...</div><div><br></div><div>On a different note: this mailing list is really for the old version of MRtrix (0.2.X), and will eventually be phased out.

<div>Hi,</div>
<div> </div>
<div>I am trying to install mrtrix3 on a neurodebian machine (Oracle VM virtual box). I have all requirements and I successfully installed dependencies and did Git setup. I then try to build mrtrix, but after typing ./configure it runs up to 51/432 and then
stops, giving me the following error message: </div>
<div> </div>
<div> </div>
<div>ERROR: ( 51/432) [CC] release/cmd/mrregister.o</div>
<div>ERROR: ( 51/432) [CC] release/cmd/mrregister.o</div>

<div>failed with output</div>
<div>virtual memory exhausted: Cannot allocate memory</div>
<div> </div>
<div>I am not sure how to solve the issue…</div>
<div> </div>
<div>Thanks,</div>
