Re: [MirageOS-devel] Problems building mirage-skeleton stackv4

[David Scott <scott.dj@xxxxxxxxx>]

Hi,

The problem is triggered by the "mirage" command-line tool attempting to replace its own binary:

> stackv4      # cp: cannot create regular file `/root/.opam/system/bin/mirage': Text file busy

As a workaround, try running "opam upgrade mirage" and then try "make all" again -- by pre-upgrading mirage you should bypass the problem.

I had a quick scan through the mirage/mirage issues list on github and couldn't spot this one. It's probably worth filing this as a bug so we don't forget. Perhaps we could fix it by changing mirage/mirage opam install to "mv mirage mirage.bak; cp newmirage mirage".

Cheers,

Dave

Hi there! Any pointers on the following error I'm getting when trying to build mirage-skeleton on a fresh build server? Ubuntu precise, 12.04.1 LTS.

Thanks!
